Data to: Opportunities for the conservation of migratory birds to benefit threatened resident vertebrates in the Neotropics

Neotropical countries receive financing and effort from temperate nations to aid the conservation of migratory species that move between temperate and tropical regions. If allocated strategically, these resources could simultaneously contribute to other conservation initiatives. In this study, we use novel distribution maps to show how those resources could aid planning for the recovery of threatened resident vertebrates.
Using eBird-based relative abundance estimates, we first identified areas with high richness of Neotropical migrant landbirds of conservation concern (23 species) during the stationary nonbreeding period. Within these areas, we then identified threatened species richness, projected forest loss, and conducted a prioritization for 1,261 red-listed vertebrates using Terrestrial Area-of-Habitat maps.
Richness for migrants was greatest along a corridor from the Yucatan peninsula south to the northern Andes but also included southwest Mexico and Hispaniola. Protected areas a...
