There are dozens of birds in the National Zoo's flamingo flock, some of which have been living at the Zoo since 1965! You may notice smaller, gray birds among the adult flamingos, these are flamingo chicks which hatched in the spring.
The Zoo is home to many apes. Orangutans and western lowland gorillas can be found at the Great Ape House. Smaller primates, including golden lion tamarins, Geoffroy's marmosets, and howler monkeys, can be found in the Small Mammal House.
