|Comments are welcome on the identity of this frigatebird, photographed on Michaelmas Cay in the Great Barrier Reef, Queensland, Australia, in early August 2009.|
|The dark head and throat suggest Lesser Frigatebird, though that species should typically show a more pointed white 'spur' on the axillaries, with the black on the lower underparts protruding more into the white breast.|
Seeking closure on the ID, I emailed images to a friend in Queensland for comment. To my surprise, he felt unsure too, so here I throw the question open to anyone who feels suitably qualified to give a firmer view. Doubtless it's more straightforward for those with frequent experience of both species, so I look forward to learning.
In the meantime, here's a few more images from that trip to Michaelmas Cay:

|Greater Crested Terns on the beach - what price one of these in Europe?|
