Frigatebirds are the "Pirates of the Air" because they steal food from other seabirds as they are flying. I even saw 3 Frigatebirds trying to steal pieces of fish from at large Sea Lion! In the late afternoons we enjoyed seeing several Frigatebirds soaring above the bow of our catamaran taking advantage of the air uplift.
The female Frigatebird has a white breast.
This female Frigatebird landed on our boat to rest her wings.
