Standing on the pier in Naples and watching the pelicans dive for their food is fascinating.
Pelicans are very well taken care of in Florida and their population has increased since the use of DDT was banned in 1972. There are three types of pelicans in America all known under the name of brown pelican. But only two of these species dive into the waters for their food.
The brown pelican mainly feeds on fish, but occasionally eats amphibians, crustaceans, and the eggs and nestlings of birds. It nests in colonies in secluded areas, often on islands, vegetated land among sand dunes, thickets of shrubs and trees.
Females lay two or three oval, chalky white eggs. Incubation takes 28 to 30 days with both sexes sharing duties. The newly hatched chicks are pink, turning gray or black within 4 to 14 days. About 63 days are needed for chicks to fledge. Six to 9 weeks after hatching, the juveniles leave the nest, and gather into small groups known as pods.
On this particular day, there were several pelicans flying around on the pier, all diving in and grabbing fish. I can honestly say they were much more successful in catching their meal in comparison to the fishermen who wee standing around with several fishing poles and coming up empty handed. (source)
