Habitat:
It frequents second growth forest, Hibiscus thickets and streamside vine-tangles, feeding on large insects and lizards Anolis sp. (Stiles and Skutch 1989). There are apparently no published observations of the species nesting (T. Sherry in litt. 2007).


Range:
Coccyzus ferrugineus is endemic to Cocos Island, c.500 km from the coast of Costa Rica. It is widespread and probably under-recorded in suitable habitat, but the extent of such habitat is very limited (F. G. Stiles in litt. 1999). The total population is probably significantly below 1,000 individuals, and it is the least common of the endemic land birds on the island.


Conservation:
Conservation Actions Underway
Cocos Island has been designated as a national park, but no substantive measures have been taken to reduce populations of introduced mammals (F. G. Stiles in litt. 1999).

Conservation Actions Proposed
Conduct surveys to estimate the population, perhaps using call play-back and mist-netting (T. Sherry in litt. 2007). Monitor population trends through regular surveys. Carry out research into the species's breeding biology (T. Sherry in litt. 2007). Study the impact of introduced mammals. Begin to eradicate introduced mammals where feasible.
