Male Brandt's Cormorant Skypointing, Courtship Display, Breeding Plumage with blue throat and a few white pin-feathers, La Jolla. Skypointing is an interesting courtship behavior that many birds practice. Among Brandt's Cormorants the male performs this, likely as a way of attracting a mate to the nest he has built by showing off his striking blue throat. He tips his head backward showing off his striking blue throat, and partially raises his wings. Seen here on seacliffs above the ocean.
