The Brown and Peruvian Pelicans
10,000 Birds
OCTOBER 8, 2015
The Brown Pelican and the Peruvian Pelican are closely related and once were considered the same species. Some pesticides killed pelicans directly, while DDT contamination led to thin-shelled eggs that broke under the weight of the parents. The species reached pre-pesticide numbers by the late 1990s and was fully delisted in 2009.
