Nice to see the Glossy Black Cockatoos passing through again. These are vulnerable birds with a very restricted diet of casuarina seeds. We were fortunate to see them a few days ago, a pair with 2 young ones probably from this season. Glossy Black's are much smaller than the more common Yellow-tailed Black Cockatoo. Males have the distinctive red tail, while the females have yellow face and neck patches. Another species that require the rare big tree hollow to breed.
