Magnificent Frigatebird (Male)

Frigatebirds soar effortlessly over the ocean rarely flapping their long, pterodactyl-like wings and using the long tail to steer. Though they are frequently seen soaring, they are masters of pursuit. They chase other birds including frigatebirds, forcing them to regurgitate their recent meal, which they scoop up before it hits the water. Their gracefulness ends as soon as they head towards land, where they awkwardly perch in low shrubs and trees. Their strong toes help them hold onto branches, posts, and boat masts, but their small feet in combination with their short legs makes it nearly impossible for them to walk on land. On land, males often flutter the balloonlike throat sac (or "gular pouch") to cool off. Males and females also regulate their body temperature by holding up their wings up to sun themselves. To get airborne, they flap a few times and use the wind to help lift them into the air. Male Magnificent Frigatebirds gather in groups to court females. They perch in low trees and shrubs with their red throat sac inflated like a balloon and clatter their bills, waving their heads back and forth, and calling at females flying overhead. Females choose a mate and begin building a nest on the male's display perch. The pair stays together for up to 3 months, after which the male leaves and the female raises the chick alone for up to 1 year.
