Hi Laurie

Looking at your photos, there does seem to be whitish flecked feathers between its eyes but it looks different i think because of being fluffed up. The juveniles start out alot whiter so i would assume that it is an older bird rather than younger. But i am certainly no expert! I have just been looking at some of my own photos for confirmation. I have photos of a young bird which show the body and head all white except for large grey "goggles".
Love to hear others thoughts too.

Cheers
Dave

A mate of mine wanted to see a Powerful Owl, so yesterday we went out to JC Slaughter Falls [Mt Coot-tha, Brisbane]. We found one of the two owls that have been regularly seen in the vicinity, and were quickly joined by Chris Barnes. We all took plenty of photographs, from several angles.

The bird in question was quite "puffed up", particularly around its chest. The feature that took my attention, however, was its particularly dark head and face - colourwise, rather like a dark morph Wedge-tailed Eagle. It totally lacked the pale feathers I would have expected to see on its forehead / between its eyes. In some respects, this made the bird look more hawk-like.

It's plumage was also a bit thin around the base of its lower mandible, so the yellow colour was readily apparent.

I have placed an image on ABID - you can see it at http:// www.aviceda.org/abid/newimages.php

I would be interested in people's interpretation of this bird's plumage - is it a youngish bird?

Regards, Laurie.
