Vireo caribaeus |
The St. Andrew Vireo (Vireo caribaeus) is a critically endangered endemic species. Studies for this species have been developed in recent years, focused on assessing the population status and learn some ecological aspects, but there was a need to fill information gaps in their reproductive biology in order to cover all aspects that can generate guidelines for adequate protection to ensure the survival of the species in the long term on the island of San Andres, an ecosystem which is as vulnerable as the island territory.
Through banding of the species on the island of San Andrés data has been obtained like this species is restricted to an extremely small range and endemic to an island where it is susceptible to stochastic events and could be rapidly affected. However it has been found to be one of the most common species on the island, tolerant of habitat degradation and apparently there is no evidence of a significant population decline.
It feeds mainly on caterpillars and small arthropods. The preferred nesting habitat is sparse forest, because of the diversity of plants and animals found there and which represent important food source especially for juveniles.
It is found in almost all habitats on the island, sparse forest, dense forest, wetlands, mangroves and coastal vegetation. Less common in pastures.
