Australian Brush-turkey

Bushfire had ravaged Crows Nest National Park just a few days before I followed this Australian Brush-turkey around as it foraged amongst the ash.

This odd looking megapode had a remarkable start in life. It hatched from an egg that weighed 12% of its mother’s weight. It was snuggled in a large mound of organic matter built by its father and containing about 50 eggs laid by several different females. Its gender depended on the temperature in the mound while the egg was developing. The father attempted to keep the mound at about 33-38 degrees Celsius which he did by digging into the mound and checking the temperature by poking his bill into the compost. He added more organic matter if the temperature was low, and removed some if the temperature was high. More eggs develop as male if the temperature is low. Each egg has a large yolk which enabled the chick to be very well developed when it hatched. It wasn’t a helpless, featherless, scrawny, pink-skinned hatchling when it dug its way out of the mound but a strong, well feathered chick that could fly within hours.

The turkey raked vigorously at the ground in search of invertebrates and seeds. My shutter speed was not fast enough in the image above to freeze the movement of its leg. Evidence of the bushfire can be seen along with new shoots that are already emerging. Bushfires have a devastating impact on Australian wildlife, people often talk about how quickly the bush regenerates but it takes far longer for fauna to reestablish itself.

It took the turkey quite a few tugs to pull this shoot from the ground. I like the scalloped edges of the turkey’s feathers and the way its tail is held laterally. The bare red skin of its head and the saggy yellow throat wattle are striking features of this bird that is 70cm long and weighs over 2 kilograms.

The image above is a close up of the turkey’s huge foot as it rakes through the ashes of the bushfire; it looks reptilian.

Looking at the camera settings, shooting in aperture priority with no exposure compensation, I’m puzzled by the slow speeds despite the varying ISO and wide open aperture. If you can explain what was happening please let me know, either via comments (below) or email (see contact page).

After having had images stolen I am experimenting with slightly lower resolution images this week but expect to return to higher resolution images next week.

If you are one of the readers who is concerned about the annual Australian harvesting of hundreds of thousands of Short-tailed Shearwater chicks (see Short-tailed bundle of fluff) please contact RSPCA Tasmania to ask about a campaign: rspca@rspcatas.org.au  NB the Tasmanian Parks & Wildlife link in last week’s post details how to catch and kill chicks, including methods that are not condoned but are used, please do not access the link if you will find it upsetting – not everyone needs to know the gory details to know that chick harvesting is inappropriate in the 21st century.

Happy birding, Kim

  • Kim, this is a fascinating bird and post! Thoroughly delightful.

  • He is a colorful dude! Great shots!

      The red and yellow really stood out with so much of the area blackened from the bushfire. Actually a long distance shot would have been worthwhile … too late now.

    Brilliant Kim – a real look into the ancient world of the small dinosaur, or this land before we arrived!
    Not sure about your query on exposure/shutter speeds – they look pretty much what I’d expect, besides, you’re the master in this field. I spend a lot of time shooting birds up Chandler Hill and surrounding areas but can rarely match the clarity of your wonderful shots.
    Suggest you stick with the lower resolution on the web if you want to stop serious pirates. The detail is still superb for on screen viewing.
    Best wishes
    John

      Thanks heaps for the feedback John! It’s good to know that the lower res images are okay to stick with and I appreciate your thoughts on exposure/shutter speeds. I haven’t walked in that area for years, hmmm, time for another visit I think 🙂

  • Wow, love the pic of the foot digging 🙂 You are really getting some good shots Kim
