Barn Swallow (Juvenile)
Is it a Barn Swallow and House Swift Hybrid? It was flying within a group of House Swift at Hung Fa Leung on 2017-06-05.

I can't see why this isn't just a juvenile Barn Swallow. Also, bear in mind that swallow are passerines and swifts are non-passerine and as such are not even closely related. Bird hybrids in the wild tend to be between closely related species. Such a hybrid pair (between individuals in two different orders) is probably unprecedented, at least within birds.

Thanks very much for such a clear explaination.
