Cocky Count

I participated in the Red-tailed Black-Cockatoo Recovery Project annual count today. The South Eastern Red-tailed Black-Cockatoo sub-species occurs only in SE South Australia and SW Victoria. With an estimated population of approx. 1400 birds it is in danger of extinction.

Except for the short period of the year when Buloke is fruiting (Jan-Mar), Red-tailed Black-Cockatoos feed almost exclusively on stringybark fruits, so the search concentrated on areas of stringybark forest. My allocated search area was a patchy area of stringybark forest, river red gum woodland and swampy grassland in SW Victoria north of Casterton and west of Dergholm.

The cockatoos can most easily be found by listening for their characteristic calls and searching for evidence of feeding on the ground - the birds tear off leaves and small branches, chew the fruit then drop the remains on the ground.

I did manage to find two small flocks during the nearly 6 hours and 67.5 km of searching the tracks. Not a great shot but the primary purpose was to find and count the birds not photograph them. These were part of a flock of 16 birds.

Dryandra Woodlands

Had a quick trip to Perth this week for work and the cheapest flight home was the Sunday morning "red-eye", which gave me the opportunity to visit the Dryandra Woodlands for the first time. Dryandra is approx. 170km SE of Perth (see map). Driving down Highway 30, I got to Jarrahdale State Forest and Midgegoroo National Park just after sunrise and found a flock of Red-tailed Black-Cockatoos high in the trees. Still low light and they were moving around a lot but managed a few shots of this pair

The road also passes through farmland and the roadside vegetation was full of early morning avian activity with this Brown Falcon a highlight.

It was still early morning when I reached the Dryandra Woodlands

and one for the life-time list:

On the drive back to Perth I headed out to the coast to visit Point Peron. There was an approaching storm so didn't stay long but there were lots of cormorants, pelicans and gulls flying past the lookout.
