The U.S. Neotropical Migratory Bird Conservation Act sponsors an annual competitive grants program to support the conservation of neotropical migratory birds and their habitats in the USA, Canada, Latin America, and the Caribbean. At least 75 percent of funding supports projects outside the USA. Grant requests have to be matched by partner contributions at no less than a 3-to-1 ratio. Eligibility to compete for funding is unrestricted. Applications should be submitted in English, but the program will accept accompanying versions of the application in Spanish and Portuguese. The application deadline is 31 October 2024. Find instructions
