Brown Pelican



The Brown Pelican is a comically elegant bird with an oversized bill, sinuous neck, and big, dark body. Squadrons glide above the surf along southern and western coasts, rising and falling in a graceful echo of the waves. They feed by plunge-diving from high up, using the force of impact to stun small fish before scooping them up. They are fairly common today—an excellent example of a species’ recovery from pesticide pollution that once placed them at the brink of extinction.

This photograph was taken in Tampa Bay in 2012. but Susanne and I saw numerous brown pelicans in Charleston but we were able to capture the best photo that reflected this birds true beauty.

While the Brown Pelican is draining the water from its bill after a dive, gulls often try to steal the fish right out of its pouch—sometimes while perching on the pelican's head. Pelicans themselves are not above stealing fish, as they follow fishing boats and hang around piers for handouts. Pelicans incubate their eggs with the skin of their feet, essentially standing on the eggs to keep them warm. In the mid-twentieth century the pesticide DDT caused pelicans to lay thinner eggs that cracked under the weight of incubating parents. After nearly disappearing from North America in the 1960s and 1970s, Brown Pelicans made a full comeback thanks to pesticide regulations. During a dive, the Brown Pelican tucks its head and rotates its body to the left. This maneuver is probably to cushion the trachea and esophagus—which are found on the right side of the neck—from the impact.
