Disfigured bill on sulphur-crested cockatoo at Lyneham

[Maryanne Gates <>]

The bird in the picture does not appear to have beak and feather disease.  It is more likely that it damaged its beak at some time causing the irregular growth.

A disfigured bill on a sulphur-crested cockatoo is generally beak and
feather disease. It probably is on this one, but the feathers appear normal
on these photos.

I spotted this bird near the Lyneham wetlands pond.

Its bill seems to be in three parts. The top part looks like the what should
have been the top part of the bill, but below it is a second top bill, which
has a distorted growth growing straight outwards.
