Enderbury ;:ere first recorded by POBSP personnel, 
t The avifauna is very similar to that found on Howland Island, 300 miles 
to the northwest. Most differences are probably caus^ed by those environmental 
features by which Enderbury differes from Howland (e.g. presence on a central 
lagoon, larger size and larger number of trees). Phoenix: Island, only 40 miles 
southwest of Enderbury, has six more breeding s ecies than Enderbury despite the # 
absence of any trees. Two procell-rids formerly nested on Enderbury and five of th<

Enderbury 1 s present lack of procell ..rid species is probably the result of the 
introduction of cats in the late 1930 ? s 
The island was mined in the 1880 for the guano deposits and also supported a 
small American colony from 1938-1942. Both occupancies undoubtedly resulted in lower 
populations of nesting species.
