ACS recently returned from the Yucatan where we are working the Cornell Lab of Ornithology and CONABIO (Comisión Nacional para el Conocimiento y Uso de la Biodiversidad). Over the next six months, we will be helping CONABIO understand what influences participation in their community-based avian monitoring program. One of the longest-running programs of its type, the program consists of a network of dozens of community groups monitoring birds across all of Mexico.
