Author's notes

Thought this was a juvenile crested tern at first, but seems too small. Was very vocal like a young one waiting to be fed. Approx 25-30cm in length, ? little tern

Hi Helen, It fits the images of a Crested Tern in non-breeding plumage in our CSIRO field guide pretty closely, with that hint of a crest, and the fact that the plumage on the back is uniform grey, not speckled. So maybe not being vocal about feeding, but being aggressive towards other birds nearby? The book gives body weight, not length, but Little Terns are much smaller than Crested Terns (42-65 grams compared with 275-371g) so just being a bit small isn't going to make it a Little!

Also, the fact that it has black legs shows that it is a Crested Tern. Little Terns have yellow legs, at least when as an adult in breeding mode. If it was a Little Tern in non-breeding mode it wouldn’t have a yellow bill.

Thanks Jackie and Paul, that all makes sense now. I had better brush up on terns! Helen

Good luck with that one - they're subtle. Nine times out of ten they'll be cresteds, but just occasionally something more interesting turns up, and it's good to be able to pick up on that.
