Carnaby’s chicks on campus

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.

Crested Terns on Penguin Island

Catch of the day

Every time I’ve been to Penguin Island, I’ve been fascinated by the Crested Terns (Sterna bergii). The first time I visited with my camera, I watched for ages as a group of terns splashed about in the small waves on the more protected side of the island.

In late November last year, the terns were busy raising their families. They started out with the young hidden in the vegetation and the poor parents battling to get fish to the chicks without losing their catch to the very determined Silver Gulls.

Two weeks later, the colony had moved down onto the beach.

The gulls were still very much in evidence but not seeming as much of a threat, probably as the chicks were older. I’m not sure how the parents find their offspring in amongst all the chaos.

Hopefully those chicks are all grown up now, and in juvenile plumage like the bird on the left below.

Penguin Island

Penguin Island is one of my favourite places to visit near Perth. It’s a bit of a drive from home south to Rockingham but then just a short ferry ride to the island, which forms part of the Shoalwater Islands Marine Park. Bridled Terns breed here in summer – it is an awesome experience visiting when they are in residence as they are so close and flying all around you.
The birds and other animals are so much more relaxed than on the mainland making it easier to get close to them (sometime they get too close). I would love to be able to get over to Penguin Island early to get the soft light but as the first ferry is at 9 am I may have to learn how to kayak (and be brave enough to take my camera!).

If you’re lucky you’ll spot a wild Little Penguin – the smallest penguin species, found on the southern coast of Australia and around New Zealand. In summer, you sometimes see a couple of penguins hiding under the boardwalks but most of them disappear early in the morning to fish all day, returning at sunset. The island is closed to visitors in winter when the colony (about 1000 pairs) gets into breeding mode. The Little Penguin below is a late fledgling I spotted in the middle of the day – he probably tired of waiting for his parents to return and decided to try fishing for himself. Hopefully he made it to adulthood.

Another unusual sight I came across was this pair of Mute Swans in the sea near the jetty. Mute Swans are an introduced species in Australia; there is a breeding colony at Northam (about 100 km away) but this pair were seen in the Rockingham area for a while.
