Weighing in at around 10 lbs with a wingspan of up to 8 feet, the brown pelican (Pelecanus occidentalis) is an impressive bird. Sure, it's the smallest of the pelican species, but it hardly lacks in size. Along the shores of Florida and the Gulf Coast, these birds are common. They swarm docks and piers wherever fish are being caught and cleaned, and their acrobatic fishing techniques often catch the eyes of tourists and locals alike.
But it wasn't always so easy to see these large birds in action. DDT use decimated the pelican population to such low numbers that in 1970, it was placed under the protection of the Endangered Species Preservation Act, the first version of the current Endangered Species Act. DDT interfered with the shell formation in pelican young, making their shells too thin and unable to support the growing chick. Pelicans were one of the many species that DDT damaged, leading to a nation-wide ban of the pesticide's use in 1972. Since then, pelican populations have been fighting back to regain their numbers.
The removal of this species from the Endangered Species Act is a huge success for conservation efforts. While fewer laws now watch over the pelicans, it's important to note that they are not completely unprotected. Additional federal laws, such as the Migratory Bird Treaty Act and the Lacey Act, will continue to protect the brown pelican and its nests and eggs. U.S. Fish and Wildlife will also continue to keep a watchful eye via their Post-Delisting Monitoring Plan, which is designed to monitor and verify that the recovered, delisted population remains secure from the risk of extinction once the protections of the ESA are removed. If the pelican shows significant declines, they won't hesitate to relist them.
