Hi David,

Thank you for your reply!  I have come to the conclusion that Frigatebird
identification is very challenging!  After analyzing 100's of photographs
of this bird (which is still here), the white patch on the chest looks
very different from various angles.  Some have suggested it is Christmas
Island Frigatebird while others say it is looking more like a Lesser
Frigatebird, but after reading your comments I found posted online, I am
wondering if it is immature Greater? In some photos, the front margin
looks straight, while in others it looks pinched and more diamond shape on
front and back margins (without the spurs).  I also noticed in a few
pictures with the light straight on, there is a bit of brownish/reddish
colour on the throat area.  The bill does look quite long from some
angles.  Attaching a few more photos to show the coloration as well as
other views of chest. I am so curious as to what it is doing here and how
long it will stay.  Amazing to watch it fishing on the shallow reefs!

Thank you for your assistance if you have time to look at the photos and
help me identify this one!  :-)
Kind regards,
