The brown areas on the chest and flanks of the bird in the photo seem to
rule out the other species which don't seem to have noticeable areas of
brown plumage. I am sticking with Ascension Frigatebird.

Hello Steve. Juvenile/immature Frigatebirds are notoriously difficult to
separate, but the white around the armpits leading into the wings suggests
Lesser Frigatebird to me. I think Ascension Frigatebird would be well out of
range. According to Pizzey and Knight, Juvenile Great Frigatebirds are "not
safely separated" from other Frigatebirds.

G'day all
My friends on the Tanzanian equivalent of birding-aus are currently
wrestling with the identification of a frigatebird that has been frequenting
some of the nicer beach-side suburbs of Dar es Salaam. They have asked me
to post some photos on birding-aus for the Australian experts to examine.
So there are four photos here:

I'll pass on any opinions that emerge.
Cheers
Steve
