Galah x Little Corella

It may not be possible to determine from the photo which species of Corella was involved with this hybrid.  One person suggested Little Corella but without providing rationale.  Mark now informs us that this bird was with a flock of about 1000 Litlle Corellas which seems quite good circumstantial evidence in support of Little Corella involvement, though it may well be that a Galah x Western Corella hybrid would look extremely close to this.

  1. Wow, what an awesome bird.

    So in WA there is both little corella as well as western corella (a split from long-billed corella). These two birds are pretty much identical except in the amount of red on the front of the bird, and the length of the "hook" on the upper mandible (hence long-billed corella).

    The only way to separate a bird like this would be a clear picture of the bill that isn't hidden, so we can analyze the bill better. Maybe western corella does not occur in the part of WA this was taken though?

  2. Thanks for this (and sorry for the delay). I can't add much but maybe someone else might be able to comment on the status of Western Corella here.

  5. Thanks Mark - I guess that's quite strong circumstantial evidence that Little Corella is the Corella species involved. I think I'll upgrade the "possible" qualifier to "probable".
