I was driving down to Upolu for my usual walk when I saw a few Great Frigatebirds off in the distance. They seemed to be heading my way, so I pulled over and waited. As I did so, more appeared. They glided down towards the coast, then banked left to cross the road, which is when I took these photos.

I counted 17 in all, though there might have been more. Usually, I see these birds in ones and twos, but larger flocks like these are, apparently, not unusual. Such gatherings can be simply social, but can also improve their chances in the search for food, as well as for spotting predators, not that they have a lot of those while flying.

My bird book notes that most Great Frigatebirds seen in Hawaii are females or juveniles, but I regularly see males, which are easily identified by the red gular sac on their throat. This sac can be impressively inflated during courtship.

Thanks Brian. I meant to post this a couple of months ago and then it got lost in the abyss that is my photo files.

Beautiful shots, Graham, particularly of the red sac. You’d never get that detail with a phone. I regularly try to capture flicks of pelicans and get an average result.

I think it depends on the phone. Some are very good these days, but mine isn’t one of them. I only use it if my camera isn’t handy, which it usually is.

gorgeous birds, Graham, they do look they fly effortlessly. We saw similar frigates in Baja Mexico years ago, but not as many.

Majestic birds. Lovely shots you got of them.
Interesting how close they stay to the equator. I live pretty deep in the tropics, but I have to go even further south to see them.

They are majestic! I’m at around 20°N and they can be seen here pretty regularly.

Interesting, I’m on a more southerly latitude, but I have to go further south to see them. Maybe it is because of the large landmass
