Would like confirming if this is an immature Pacific Swallow or it is just due to fluffed up feather? Was taken in a windy cooling overcast morning. I can see quite a number of white feathers on its red face & throat. It seems still yet fully build plumage if I got it right.

Thanks.

Moulting adult. Rich rufous colour + contrasting old outer primaries + lots of feather-bases exposed.
