Channel-billed Cuckoo |
The juvenile Channel-billed Cuckoo being fostered by a hapless Pied Currawong in our Sunshine Coast garden at Ninderry continues to thrive.

But there's a curious twist. The Pied Currawong feeding the cuckoo is bald. It appears to have lost the feathers from its head.

There are two currawongs, presumably the breeding pair, but only the bald one appears to do the feeding.

At feeding time, the much smaller currawong inserts it head quite a way into the mouth of the cuckoo (deeper than in the image above, but you get the picture). The extent of feather loss appears to approximate the area of currawong head that enters the cuckoo's mouth. So the question: Is the currawong bald because its feathers have been lost in the cuckoo feeding process?

Glossy Ibis |
Elsewhere, at the Parklakes Wetlands, the Australian Painted Snipe (1), Australian Little Bittern (2), Baillon's Crake (3) and Spotless Crake (1) were all spotted yesterday morning. At a small pool nearby, a party of 15 Glossy Ibis was present. At Dunethin Rocks on the way home, a Nankeen Night Heron was roosting in the mangroves.

Eastern Grey Kangaroo |
Saturday was the hottest day on record in much of the Sunshine Coast, with the temperature reaching 42 at Yandina and 39 at Ninderry. The big adult male Eastern Grey Kangaroo made good use of the birdbaths, as did the obviously heat-stressed birds.
