A pair of Beach Stone-curlew Esacus magnirostris has bred regularly on Dowardee Island in Port Stephens, New South Wales since 2011. I provide details and describe various behavioural and plumage-related observations, made in studies of the adult birds and their chicks.

 

 


INTRODUCTION

 

Since May 2011 a pair of Beach Stone-curlew Esacus magnirostris have been resident in Port Stephens.  The pair’s activity has been centred around Soldiers Point.  Soldiers Point is geographically central within the Port Stephens estuary with tidal flats for feeding and nearby undisturbed islands for refuge.  During six of the seven summers following their arrival the birds have successfully raised a single chick that has appeared to reach adulthood. The breeding activity has occurred on Dowardee Island to the west of Soldiers Point.

 

I first saw two birds that I did not recognise, on 20 May 2011 late in the afternoon on the western side of Soldiers Point opposite Dowardee Island.  A beachside resident commented to me “they have been around for a couple of days”. So this would be very close to their actual arrival date.  I photographed them a short while later and established their identity as Beach Stone-curlew.  This was the beginning of seven years thus far of observation of these birds during which time they have successfully raised six young. The bird’s status as Critically Endangered under the Biodiversity Conservation Act 2016 (NSW) has seen them feature on local and national television as their presence focused a major conservation effort to protect their habitat.  

 

Marchant & Higgins (1993) is an excellent source of background information on this species, then known as the Beach Thick-knee, although the distribution information for NSW is out of date.  In 1993 the range was limited to northern Australia including northern parts of New South Wales. Queensland continues to be a stronghold (Freeman 2003) but the range has expanded southwards (Rohweder 2003; Roderick & Stuart 2016; Mo 2016). The breeding range also has extended southwards (Clancy & Christiansen 1980; Hole et al. 2001).

 

The first confirmed record for the Hunter Region was of a single bird at Manning Point in 1993 (Stuart 1994), with the first confirmed breeding for the Region in 1998 at Harrington (Hole et al. 2003). Hunter Bird Observers Club (HBOC) records show that breeding or breeding attempts have continued annually in the Manning River estuary to this date (Stuart 1999-2018).  Although records from the Hunter Estuary remain infrequent (single birds present in December 2002 and October-November 2015) there have been many records from around Port Stephens after a single bird was first recorded (on Corrie Island) in February 2006 (Stuart 2007). Since I first saw a pair of Beach Stone-curlew at Soldiers Point in 2011, I and others have recorded them many times in the Soldiers Point area or on Dowardee Island which is situated c. 350 m offshore from Soldiers Point. Mo (2016) reported that the pair bred in the area, citing in evidence some articles by me which had appeared in HBOC newsletters. In this article, I present details in relation to breeding by the Soldiers Point / Dowardee Island pair, and I describe some aspects of their behaviour which I have observed during seven years of study.

 

METHODS

 

Study Area

 

Soldiers Point (32.70S 152.06E) extends northward from the southern shoreline of the Port Stephens estuary. Soldiers Point is extensively developed with residential, commercial and community facilities. Its shoreline habitat includes sand and mudflats that support populations of invertebrates including Soldier Crab Mictyris longicarpus. Dowardee Island (32.70⁰S, 152.06⁰E) is situated approximately 350 m offshore to the west off Soldiers Point. Referred to as Oakey Island by some local Aboriginal people, the island is now controlled by the Worimi Land Council. The island had a long history associated with the oyster industry and is littered with debris from that era. Its shoreline is a mixture of mangroves (mostly Grey Mangrove Avicennia marina), some small sand beaches and rock. Sunset Beach, which I will refer to subsequently, is the beach on the western side of Soldiers Point extending from the Soldiers Point Marina to the southern end of Pearson Park.

 

Observations

 

Since 2004 I have been fortunate to reside close to the shoreline of Soldiers Point. I have had the free time and interest to enjoy countless hours of casual observation of the natural life of Soldiers Point. I have also kayaked extensively around the study area. Much of my bird observations have been associated with a strong interest in photography. I trained in the navy as a photographer and have taken many photographs to record the Beach Stone-curlew’s presence and behaviour during its time here. When attempting to establish the birds breeding on Dowardee Island I have made visual observations aided by binoculars while on the island and also from my kayak. I have always tried to minimize my impact on
the pair, especially when the pair is on Dowardee Island.

 

 

RESULTS

 

Birds’ Range within Port Stephens

 

I will concentrate my comments to the area around Soldiers Point; however, the Beach Stone-curlew has been observed over a wide area of the Port Stephens estuary. Sightings have been made by members of HBOC individually and also during the twice-yearly shorebird survey conducted with the support of NSW Office of Environment and Heritage. The Beach Stone-curlew pair can be observed around Soldiers Point and the wider estuary for much of the year, but from late spring for several months they are not sighted on the ‘mainland’.

 

Breeding

 

On six of the seven summers since their arrival, the Beach Stone-curlew pair has successfully produced a chick able to make the flight from Dowardee Island to Soldiers Point, feed independently and grow toward maturity. I have photographed adults with a chick in most breeding seasons. Figure 1 is a collage of such photos taken over this period.

Plumage transition

 

Clancy (1986) described some of the plumage changes observed when a juvenile bird at Red Rock transitioned to adult plumage. His work is thorough and follows a chick from newly hatched to flying and I would commend this article to the reader wanting to know more. He notes that, “by week 7 the juvenile more closely resembles an adult” and further notes the bird cannot fly at this stage (Clancy 1986).

 

My observations at Soldiers Point were of birds capable of sufficiently strong flight to have made the journey there. I did not see the juvenile that I photographed on Dowardee Island in 2018 fly; however it looked similar in size and appearance to other juveniles I had seen in February of prior years. There is a gap in the literature regarding the timeframe towards adult plumage. A composite image showing the 2014–15 chick (Figure 2) reveals some information.  Some areas to note as the bird ages are: more marked definition between the yellow and dark areas of the bill; decreasing size of the white patch on the side of head; decreasing amount of light brown colour and flecking in the feathering; changing presence and definition in the white ‘shoulder’ wing markings.

 

 

 

Figure 2. Three views, taken at 4-5 week intervals in 2015, showing changes to the 2014–15 chick’s plumage.

 

The illustration of a juvenile Beach Stone-curlew in Marchant & Higgins (1993, Plate 55) shows two distinct white areas on the bird’s head – a supercilium and a large white auricular spot, whereas in the illustrations of the adults the two areas of white are joined. The accompanying text noted that only one Australian individual juvenile had been available and that juveniles from the Philippines did not have that characteristic. Figure 2 clearly shows the 2014–15 Port Stephens juvenile to have a single large area of white. Inspection of available close-up head images of juveniles from the 2011–12, 2013–14, 2015–16 and 2017–18 breeding seasons revealed similar head  patterns to the 2014–15 juvenile (Figure 3). This suggests that the juvenile illustrated in Marchant & Higgins (1993) may have been aberrant. However, for the 2015–16 and 2017–18 chicks there was narrowing of the white area and the odd darker feather was present.

Behavioural Observations

 

I strongly commend Marchant & Higgins (1993) to anyone who wants to garner information on this species.  In this section I will occasionally quote from that reference and compare that to some of my local observations.

 

Feeding

The Beach Stone-curlew in Port Stephens feed predominantly on Soldier Crabs on the exposed tidal flats.  I have seen them hunting for other crab species amongst rocks on occasion. The name ‘magnirostris’ means ‘big beak’ in Latin (Marchant & Higgins 1993). The beak, although big in profile, is a relatively narrow wedge when viewed from above. The feeding style varies from simply grabbing Soldier Crabs when they are above the sand, to plunging their beak deep in the sand to catch their prey. Individual birds quickly eat up to six Soldier Crabs and then rest or roost. On the southern end of Sunset Beach, a storm-water drain pipe usually has at least a trickle of fresh water coming from it. If the Beach Stone-curlew pair is on Sunset Beach they usually end up near the drain pipe where I have regularly seen them drink, and if enough water is present they bathe.  I believe the birds feed at night; however when I have attempted to observe them they have taken flight even when I used a red light source to view them.

 

Roosting

Under this heading Marchant & Higgins (1993) record that during one period of study, one group of 3 birds “sat, squatted or stood for 67% of the time and that the birds spend 58% of their time in the sun”.  My local observations support this. When Soldier Crabs are walking about in large numbers these birds can grab their food very quickly and so have plenty of time to rest. Anyone wishing to view Port Stephens Beach Stone-curlew would be advised to look for locations sheltered from the wind and preferably where there is sunshine. I have observed them squatting in warm dry sand high up on beaches and sheltering from the wind near eroded embankments. They appear to value warmth which probably would help them conserve their energy resources.

 

Mobility

Although not mentioned in Marchant & Higgins (1993) the Beach Stone-curlew can walk at a very brisk pace and appear to do so easily. I have to walk quickly to keep pace with them. The pair’s ‘standard’ day on Sunset Beach is to fly straight across from Dowardee Island by the shortest route to the beach, then feed and rest alternately during the course of the low tide. During this time they usually walk approximately 450 m south to finish up near the before-mentioned drain. They do not take flight during this transit unless significantly threatened, seemingly preferring to walk.

 

Response to human activity

Marchant & Higgins (1993) states the birds are “shy in areas where often disturbed” and thereafter “often remarkably confiding and inquisitive in remote areas”.  The local pair would have regular exposure to humans in much of the Port Stephens estuary, and particularly so around Soldiers Point. It is not known what exposure to human activity the local birds had prior to their arrival. Two observations merit specific mention. On one occasion when I went to pump for fishing bait (Pink Nippers Trypaea australiensis) there were no birds in the area. On my first action with the bait pump (where sand and possibly crustacean are ejected) a single Beach Stone-curlew landed about 5 m from me.  On another occasion I observed a Beach Stone-curlew standing unperturbed whilst a family played with a soccer ball nearby.

 

Some social observations

·         I was observing a single bird on Sunset Beach. The bird looked toward Dowardee Island and called a few times fairly quietly (to my ears at least). After a short interval another bird flew across from the island and joined it. If the second bird had responded to the call it apparently had done so from at least 450 m away.

·         Recognising some threats is a learned skill. I observed a pair of adult birds with a grown but immature chick, stare upward at a White-bellied Sea-Eagle Haliaeetus leucogaster soaring well overhead, while the immature bird showed no interest in the potential threat.

·         Immature birds are easily identified by behaviour as well as plumage. They can often have a stooped submissive posture (as shown by the February 2015 chick in Figure 1) when near parent birds. Parent birds will run at the chick and strike with their beaks to ‘check’ the chick’s behaviour.

·         There seems to be a period after fledging where the parents drive the young, maturing chick away. Later (after a period of possibly some months) the nearly adult-looking bird seems to be accepted and tolerated.

·         Head bobbing was noted to be an indication of nervousness /agitation /alarm (Marchant & Higgins 1993). I have observed this behaviour locally also.

 

 

DISCUSSION

 

Breeding

 

As stated previously the Beach Stone-curlew pair has successfully reared a chick until it was able to make the flight from Dowardee Island to Soldiers Point and feed independently, on six of the seven summers since their arrival.  The Beach Stone-curlew pair can be observed around Soldiers Point and the wider estuary for much of the year, but from late spring they are not sighted on the ‘mainland’.

 

The first summer that the pair vanished from mainland Port Stephens I did not pay particular attention. The local yacht club has most of its fleet moored in between Dowardee Island and Sunset Beach. Their newsletter covering that first summer spoke in glowing terms of members witnessing the rearing of a Beach Stone-curlew chick on the beach on the eastern side of Dowardee Island. I was delighted when the pair returned to Soldiers Point with a young bird in early February, and this has been their pattern ever since. They appeared to be unsuccessful over the 2016–17 summer.

 

Since that first breeding year I have made several careful visits to Dowardee Island with the permission of the Worimi Land Council. I have also observed them from my kayak. The Beach Stone-curlew pair was always present, usually near the southwest corner of the island. The birds were head-bobbing when I first sighted them from a distance of about 80 m. When not in breeding mode they would tolerate a much closer approach whilst feeding or roosting.

 

The island, as previously stated, has much debris and relics from the heyday of the oyster industry and much plant undergrowth that provide ideal cover for nesting and also shelter for a young chick. It is not ideal territory to move about in or to spot a nest or a very young chick. Additionally my first priority has been to minimize disturbance to the birds.  As such, to this date I have not seen a confirmed nest or chick below fully-fledged development.  During some visits, I have noted the parent birds flying off and circling back quickly around the beach on the eastern side. This is a behaviour reported as being associated with breeding (Marchant & Higgins 1993).

 

On 21 February 2018, as no new chick or the adult pair had returned to the mainland, I kayaked over to Dowardee Island with camera gear. I had only just dragged my kayak up on the southeast corner beach when a single adult Beach Stone-curlew emerged from cover and postured differently to any way I had witnessed previously. Shortly after this the second adult and a fledged chick with immature plumage emerged from the same cover.

 

I have no doubt from the reports of the Yacht Club members in the first year, and from my observations since, that the resident pair of Beach Stone-curlew has bred on Dowardee Island each year.  The pair’s presence and breeding success on Dowardee Island was a very significant factor in seeing an attempt by a nearby marina to extend closer to the island blocked by the Land and Environment Court.

 

In October 2017, there was a breeding attempt by Beach Stone-curlew on the northern side of Port Stephens (Fraser & Stuart 2018).  A nest with a single egg was located on a sand dune on the southwest end of Corrie Island (32.68⁰S, 152.13⁰E). This probably represents another pair attempting to breed at Port Stephens, since the Dowardee Island pair bred again in 2017–2018.

 

 

CONCLUSION

 

It is early summer as I complete this short article. It has been two months since I sighted a lone Beach Stone-curlew on Soldiers Point. Those with the interests of these birds at heart can only hope that there is more successful breeding of this species in Port Stephens this summer.

Note added in proof: On 31 January 2019, I saw the Beach Stone-curlew pair and a submissive young bird fly from Dowardee Island and land on Sunset Beach. Thus it appears that the pair has bred again on Dowardee Island in the 2018–19 season.

Many of the photographs shown on my website have been made from 2 or more photographs.  There are lots of reasons for doing this,  but for me the two main ones are; to extend the focus in macro shots and to extend the dynamic range in landscape shots and at other times where an image goes from really dark to really bright.  I'll expand a little bit on these ideas.

Macro. With close up photography,  the higher the magnification and the closer you get to the subject the narrower the band of focus ( referred to as depth of field DOF ) becomes. To overcome this and maiintain sharp detail across the subject, multiple imges are carefully taken with a tripod mounted camera at different focus points through the area where you want to show optimal detail.  With something like a single fungi only 2 shots might be required. The 2 shots can be processed manually in software like photoshop where you place the 2 shots into aligned layers ove each other, then use masks to simply reveal the the bits of detail you want. For some insect and other  shots where multiple shots are taken I use 'stacking software'. The one I use is called Zerene Stacker, very clever software with excellent scaling and aligning ability to even align handheld shots. Zerene Stacker can be purchased from the developer - Zerene Systems. There is a free trial period to check it out, there are also tutorials on the web.  I have also used focus stacking with some landscape shots to get sharp focus from the front to the back of the image.  I'll post a few examples of different subjects below taken using focus stacking. 

 

                                                                                                               

This photo of the fungi Entoloma hochsteteri was taken with a 180mm Macro lens. 6 images were 'stacked' to get detail across the parts of the subject where I wanted it.

 

                                                                                          

This is a dead wasp that I photographed with a MPE-65mm Macro lens at around 3X lifesize. Depth of field with this set up is very thin, focus stacking of 35 images has allowed more of the subject to be shown at optimal detail.

                                                                            

This scene is taken in a fairly remote part of Dorrigo National Park - we walked some klms that day. Focus stacking 3 images from memory allows sharp detail from foreground to background.

Extending Dynamic Range.  Even the best camera sensors can't capture detail across a scene as well as our eyes. A good example of a scene that benefits from using this technique would be a shot at sunset where the sky is still relatively bright, but some foreground elements are quite dull. If you were trying to capture the scene in one shot you would have to make a choice whether to keep detail in the shadows or the highlights. The answer is to take 2 or more photos using tripod mounted equipment, expose one shot for the highlights and one for the shadows and then blend them together in photoshop using layers and masks or some special software.

                                                        

                    This photo taken at sunset would have much less foreground detail, or too bright a sky with no detail if the scene had been captured with a single photegraph.

 

                                                        

                                                                    A single exposure would not have shown detail in the darkest parts of this chasm and the sky.

I think the techniques I use give fairly natural looking results. The techniques can be pushed much further utilising techniques known as high dynamic range HDR for short. Some cameras also include the ability to use some of these techniques 'in camera' automatically.  Another area where multiple frames can be used is in night sky photography. I have done this a bit experimenting with minmising digital noise, but now don't use it as I don't find noise too big an issue if photos are taken well.  Full on astro photgraphers take literally hundreds of images and blend them in designated software to get the single frame they are after.

So once again digital photography can allow us to use techniques that would only been dreamed about in the days of film and darkroom processing. I hope I've given you some ideas to have a play with.

I went out around dawn a week or so back to photograph some insects. I found a few obliging dragonflies. As the wind picked up gradually, I needed to start using flash to freeze the movement the breeze created.

I thought it would be interesting to show the way different lighting can effect the look of a subject.  Below are 3 images of the same dragonfly taken over a couple of minutes with a little bit of information below each as to the technique used and my opinion on the result. The shots were all taken with a tripod mounted Canon5D3 with sigma 180mm Macro lens attached and cable release used to avoid camera movement. Where used the flash illumination was provided by a single 430EX flash in the hotshoe with a homemade diffuser attached.

The above photo was taken using just natural  morning light, camera setting 1/20thsec @ f8 ISO500.  Natural soft light images can look really beautiful with minimal shadows. This morning was a bit overcast so the light is a bit cool, ie a bit blue and green. Even though this was taken toward the end of the session at about 0800 the shutter speed is still low, so any wind movement blurrs detail.

In this shot taken at 1/25thsec @ f8 ISO500 I have used flash on lowish power to introduce some fill light to the photo. The colour of the dragonfly has changed a bit due to its partial illumination by the flash. The flash has also partially revealed the presence of a spider web. Fill flash ie using powered down flash is an excellent technique to eliminate or soften harsh shadows. 

In this photo flash illumination is the dominant light. The short duration of the flash freezes motiion in the image. Camera was set at 1/200th @ f11 ISO640. Because the background is further from the flash it is darker. interestingly the spiderweb is more visible in this shot as it is closer to the flash and catching more light.   Flash illumination often doesnt give as nice a 'look' to an image as natural light, but often conditions determine the technique that needs to be applied if you want to capture optimal detail.

The title to this little article is a question that people sometimes ask.  The answer will vary depending on the subject and the situation. You dont want to appear to be a predator, so dont try and sneak directly toward say a stationary bird or anything for that matter.  If trying to approach a subject a zig-zag approach with pauses is far better.

If shorebirds obviously can see me on say a tidal flat, I pick up a little bit of stick ( so my hands dont get sandy to touch my camera gear ) and stop and dig in the sand as I close the distance to the bird. I deliberatly flick sand and water about with the stick so I look like anything but a predator. I look like I'm interested in anything but birds. I've used this technique with a lot of sucess, you can often see the intended subject immeadiately relax and go back to its feeding or preening. With Red-rumped Parrots I modified the technique by pulling our bits of grass and tossong them about. While using these techniques i'm keeping low and squatting.  Often birds will come towards you. There is a limit to how close some birds will allow you to approach, so be observant for signs of nervousness and stop your approach. I know of many bird photographers who slide along on their stomachs in a sort of commando crawl on the tidal flats, often with a bit of cammo fabric on them. This certainly works, but my back ( and motivation ) is not up to it. So play to your individual strengths.

A technique that is easy, is to sit still with a log, rock or something breaking up your outline in a place where wildlife want to come to, ie where they drink or to a food tree. I think most animals are colour blind, but dont wear your brightest or most contrasty colours if you want to be inconspicuous. I have also made a simple cloth hide that goes over me and my gear which I use sometimes.

A really good way to get close to birds is to establish a bird bath of some type. Make sure it is up high enough to discourage cats. I have maintained a bird bath in bush near my home for some years and it has provided lots of good photo opportunities as well as providing safe water for birds.

Some small animals will freeze motionless as a defence. If say a reptile or amphibian chooses to do this, if you make a smooth approach and don't shake or break anything near them you can get very close.

Insect life can be approached fairly easily by using an alarm clock, ie early morning, particularly after dew or rain they can be photographed while still cool and 'sleeping'. Insects are also more photogenic when covered in dew drops. If the sun is up try not to let your shadow come on your subject, often a sure way to scare wary insects.

So there isn't one answer on how to get close, become an observer and think about the situation.  Long lenses are good but there is no substitute for closing the distance as much as possible. This will lessen the effect of camera shake and atmospherics to help you get the highest quality photos possible.

 

 

There is much to be said for creating and preserving some habitat around our homes. Its nice to be able to see birds, predatory insects and the odd lizard eating insects that may otherwise be a problem.   Quite a few of the photographs on this website have been taken in or very near our yard.   We have a very small block, but it is on a corner so I've planted some bird attracting plants on our nature strip areas. There is a series of grafted eucalypt trees that have wonderful colours. They use beautiful West Australian types grafted onto rootstock more tolerant of eastern Australian conditions.  These plants have the additional benefit of not growing very big, so ideal for suburbia. The ones we have are called Summer Red, Summer Orange, and Summer Pink. When these plants are in flower birds and bees take advantage of the abundant nectar and pollen and in the process present as reasonably obliging subjects.

So I've been taking photos of living things fairly regularly for about 10 years now at Port Stephens.  While doing this ( unless you are completely unobservant ) you see the patterns of life that present as the seasons change. Its no good looking for some insects and most migratory shorebirds in winter because they just aren't there. Reptiles are more active in the warmer months, though I did see 2 snakes a few years back on the shortest day of the year. That day was particularly wet with lots of frogs about, so maybe food had brought the snakes out. So a local event can over-ride the normal.  Winter and spring are the times for our native orchids to bloom. Winter can often be when the best sunsets occurr.   As I type this in mid November I can hear a Dollarbird outside - another summer fly in visitor

I consider myself to be a bit of an opportunistic photographer and look foward to the opportunities that come with each season. One of the spring events I look foward to is the flowering of Coral Trees. These are not native and dangerously brittle. Some of the larger Honeyeaters particularly enjoy feeding on the Coral Tree flowers. When they do some nice photos can be had particularly of Blue-faced Honeyeaters.

As I mentioned earlier local conditions can overide normal seasonal events.  This year for whatever reason the local Coral trees did not bloom. Oh well, maybe next year God willing.

It is so nice to take macro photographs using natural light, particularly early in the morning at first light. Unfortunately this requires near windless conditions, a bit of a rare commodity when you live near the coast.  The alternative is to use flash as the main light source. The short duration of the burst of flash illumination freezes motion. Using my Canon 430EX flash in manual mode on 1/16th power gives a burst of light that lasts about 1/8000th of a second, fast enough to freeze most action. The flash is set in manual mode, because if ETTL mode is used this fires a short preflash to calculate the main burst required.  Human eyes dont see this brief preflash but many insects and some birds have no trouble reacting to it in a millisecond.

Today I went out to some beachside weeds that have yellow flowers and are insect magnets. A very strong wind was blowing, but using flash and the very short working distance of my MP-E65mm lens I was able to take sharp photos with ease. The technique used is to hold the plant stem with your left hand and then rest the lens on that hand also. Subject and lens are thus 'locked together' and maintain sharp focus.

When you look through the insect galleries most of the higher magnification photos have been taken using this technique. The method is also quicker than setting up a tripod and suprisingly when approached smoothly a lens and flash a few cms away scares less subjects than setting up a tripod up at a much greater distance.  

The Blue-banded Bee shown above was photographed using the technique described in this little article.  On a thin springy little perch like this there would always be movement so no chance of sharp images without flash. The background to this photo is a leaf I'm holding between my middle and ring finger while holding the stem the bee is on with thumb and index finger. The dew drops reveal the time of day and show why this insect hasn't flown off.                                      

 

 

So yeh, one goes in the bush or long grass and occasionally you find a tick or 2 on you afterwards. No big deal, pull it out, maybe a bit red and itchy for a few days.

About a year ago all this changed for me. I had a tick attach to my inner forearm, it hurt, I was able to pull it out immediately  with my fingers. Pain continued at the location and a warm pinkness quickly  developed around the area.  The pain and redness continued to develop over the day and I eventually presented to our local Polyclinic where competent staff diagnosed cellulitis ( infection ) at the site. I was put on oral antibiotics and sent home. The condition worsened by morning and so I spent 3 days in hospital on IV antibiotics followed by ongoing oral treatment post discharge.  My doctor later confirmed what I already knew that untreated the infection would have turned to septicaemia with fatal results.  From talking with hospital staff infection post tick ‘bite’ is quite common.

I have a bit of a medical background so after this event did a fair bit of reading regarding ticks and tick-borne disease.

Here is a link to the Australian Association of Bush Regenerators page where there is all sorts of  information, and lots of useful links within    http://www.aabr.org.au/learn/publications-presentations/ticks-and-tick-borne-diseases-protecting-yourself-2/

Here is a link to an ABC  Catalyst episode on ticks and tick allergy, you can watch the video or read the transcript. http://www.abc.net.au/catalyst/stories/4177191.htm

So what do I do differently after my bad episode.  I don’t go into dense bush, you can see and photograph plenty from tracks and firetrails.  When I get home I strip off and check myself and my clothes for ticks. I wear gumboots quite a bit, long sleeves, hat and I spray insect repellant on as well.  I’ve only had one tick in me since the hospitalization ( I was lazy and didn’t do a strip search that day ) I used ‘Wartner’ freezing spray to kill the tick and had an uneventful recovery. I also keep antiseptic cream in my little bush pack and some fine tweezers.

So still enjoy the Aussie bush but be aware of the serious problems that ticks sometimes cause.  Have a look at the links above, be alert to the issues and have a plan of management worked out before you find the next tick in you.
