A quick qualification, I do acknowledge that the occasional female Lesser
Frigate can have a blue eye-ring off the east coast but it's not the normal
appearance. So the ID should rest on the shape of the white breast patch
without tabs onto the under-wing and lack of a sharply demarcated hood with
white collar.

 

Cheers Jeff.

G'day Dominic,

 

The first impression from looking at your bird is a darkish throated female
Great Frigatebird and that's what I think it is. Shifting the levels around
on your two images shows a blue eye-ring and the bird is lacking white tabs
into the underwing, none of this is good for Lesser in the Coral Sea. I
would say that the darkish throat, which is probably the reason for your
caution, is not a problem and within the spectrum for female Great
Frigatebird.

 

Cheers Jeff Davies.

I guess, seeing as Dominic didn't post it directly here, any thoughts could
be ccd to him as well as to birdingaus - his email address below.

Hi all

 

 

 

Back in August 2009 I photographed a frigatebird at Michaelmas Cay in the
Great Barrier Reef, Queensland, Australia. At the time I was uncertain as to
whether it was Greater or Lesser, and an experienced Queensland birding
friend also felt unsure about the ID. Having posted about it on my blog I
then solicited opinions on the Seabird-News Google group, but no one there
committed to a firm ID either. If anyone on ID-Frontiers with relevant
experience would be interested in commenting, I'd appreciate the feedback.

 

Images of the bird can be viewed here:

Thanks in anticipation,

 

Dominic Mitchell
