Lesser Frigatebird

Lesser Frigatebird, also known as Lesser Frigatebird, has three subspecies.

Lesser Frigatebird is a resident bird, wandering over long distances during some non-breeding seasons. Like other frigatebirds, the white-spotted frigatebird also has pirate habits, often snatching and forcing other seabirds to spit out their captured food, and then grabbing it for themselves. The white-spotted frigatebird is also a living weather instrument. When they rest on the mangroves by the sea, it indicates that a storm is coming. After the weather clears up, they often spread their wings and turn up and down to bask in the sun.

The white-spotted frigatebird mainly feeds on fish, and mainly snatches and forces other seabirds to spit out the fish they catch in a pirate-like manner, and then snatches them away before these foods fall into the sea. They also prey on crabs and other crustaceans on the beach. Sometimes they also prey on squid on the sea surface.

The white-spotted frigatebird breeds on islands in tropical oceans. The breeding season is from May to December. They nest on island trees or bushes, and rarely nest on the ground. The nest is made of plant branches and leaves. Each nest lays one egg, which is white and 60-64 mm × 43 mm in size. The incubation period is about 40 days. The chicks are late-maturing.
