Carnaby’s Cockatoos are endangered parrots endemic to the south-west of Western Australia, usually seen around Perth from late summer through to winter, when they move inland to breed. So it was a big surprise last summer when observant students discovered two pairs of these iconic birds breeding on a local university campus. As mentioned in this article, this is the first record of Carnaby’s breeding in Perth since European settlement.
As part of ongoing monitoring of Carnaby’s Cockatoos by conservation agencies, both chicks were extracted from their hollows, weighed, measured and banded on one leg with special stainless steel bands bearing unique identifying numbers. The university students set up camera traps facing the hollows to record the parents’ comings and goings and hopefully the timing of the chicks fledging. I was very lucky to be able to take some photos as part of the monitoring. The first chick, known as Chappie, was in a hollow that was difficult to see clearly, particularly in the evening. The parents come in to feed the chicks quite late in the day, when the light is very low on the horizon.
Ronnie’s hollow was in a much better spot and I was able to get some lovely images of him peeking out of his hollow and of his Dad coming in to feed him just before sunset. Anyone familiar with Carnaby’s will know that usually you hear their distinctive call well before you see them; when they are coming in to an active nest they are much more discreet and can suddenly appear as if from nowhere.
It was such a privilege to watch the last few days of Ronnie’s time in his hollow – the parents would call to him and he would think about leaving and then change his mind, and get his wings in a tangle trying to get back in to the hollow. I was expecting that when he fledged he would climb out of the hollow and spend some time on one of the nearby branches before flying away but he didn’t. His parents called to him a few times and he just launched himself out of the hollow over our heads (one of the students was with me) and disappeared over the campus.
Sadly there was no happy ending for Ronnie’s story. A few months later, we found out that he had been found injured on the side of a major road. He was taken to the Perth Zoo but was too badly hurt (probably hit by a car) and had to be euthanised. Car strikes are a major problem for Carnaby’s in urban areas – they often feed on native shrubs planted on roadsides and their tendency to take off low to the ground puts them in harm’s way. Hopefully Chappie will be luckier.
