ProAves supports the Cerulean Warbler (Dendroica cerulea) in various ways. One avenue is through Grupo Cerúleo, which is developing a conservation strategy for the species on its non-breeding grounds. The Foundation participates through conservation and research in Colombia.

Grupo Cerúleo was formed in December 2002, to develop a conservation strategy for the Cerulean Warbler on its non-breeding grounds in Colombia, Venezuela, Ecuador, Peru, and Bolivia. Known as the Non-breeding Season Group, it is a subcommittee of the Cerulean Warbler Technical Group (CWTG), which promotes a multi-species focus on wintering ground habitat conservation, including at-risk species that may coincide with the Cerulean Warbler.

The problems facing the species are related to the size and conditions of the non-breeding grounds and habitat changes on them. A solution is considered to be a priority for the future conservation of the species.

Fundación ProAves is part of this initiative, offering support through species conservation and research in Colombia.
