Overview

Distribution

Range Description

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.

Habitat and Ecology
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).

Justification
This species is classified as Vulnerable because it has a very small range and population. Introduced herbivores are degrading forests in its range, but it appears to tolerate some habitat modification and there is (as yet) no evidence of a decline in its range or population. Regular surveys are required so that trend data can be collected, and if it is found to be in decline it may warrant uplisting to Critically Endangered.

Population

Population
The total population is probably significantly below 1,000 individuals (F. G. Stiles in litt. 1999). It is placed in the band 250-999 mature individuals, equating to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.

Threats

Major Threats
Cats are potential predators of adults, fledglings and nests, whilst rats are potential nest predators. Feral deer, pigs and goats graze suitable habitat. Pigs especially devastate the lower strata and understorey of native forests and inhibit forest regeneration (Sherry 1985, F. G. Stiles in litt. 1999). On many other islands, this combination of feral mammals has caused the extinction of numerous endemic plant and animal species. There is also low-level disturbance from increasing tourism (Sherry 1985). Global climate change might pose a threat in the future, perhaps through the effects of changes in weather patterns (T. Sherry in litt. 2007).

Management

Conservation Actions

Conservation Actions
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.
