The significance of ACG's mid-elevational Caribbean forest habitat cannot be overstated, as it provides a contiguous block of undeveloped and unbroken habitats critical to the survival of many migratory bird species from the north during the winter months. Sadly, habitat loss, pesticide use and climate disruption pose significant threats to these birds, making the efforts of the BioAve team all the more crucial.

ACG’s innovative migratory bird research project, dubbed BioAve, has already tagged three Wood Thrush, a species included on the Partners in Flight Yellow Watch List for birds at most risk of extinction, and it aims to tag over 65 more migratory birds over the next year. The data collected will enable the project to understand better the challenges facing migratory birds and aid in developing conservation efforts.

The research program has been in development since 2014 and has brought together various research partners and parataxonomists at several ACG biological stations. The two MOTUS tracking towers currently in use at Maritza and Pitilla stations, with the hope of getting more online, enable the team to track these birds’ migration patterns and behavior as they traverse Central and North America to and from their breeding grounds. Two individuals tagged just this year in ACG have already flown back to their spring breeding grounds in the USA, recorded as they pass over U.S. MOTUS towers.

The BioAve project is at the forefront of efforts to conserve migratory bird species by utilizing innovative technologies to study their behavior and habitat use while collaborating with researchers and organizations across the globe to help preserve these creatures and their unique habitats.
