Costa Rica Bird Communities: Neotropical Migrants and Resident Birds
Since 1994, we have conducted research at Tortuguero, Costa Rica, in association
with the Costa Rica
Bird Observatories, Sea
Turtle Conservancy (formerly Caribbean Conservation Corporation), Instituto
Nacional de Biodiversidad Costa Rica (InBIO), Partners in Flight-Costa Rica,
and other cooperators. Our primary objective is to conduct long-term
monitoring for the study of neotropical migrant and resident
landbirds with the collaboration of Costa Ricans to further the knowledge
and understanding of Costa Rican birds through bird banding and census. When
the station was begun, it was the only operation to our knowledge regularly
monitoring the landbirds of the country on a consistent basis. Costa
Rica Bird Observatories has expanded these operations to five monitoring
sites in varied habitats across Costa Rica.
Internships available: If you are
interested in being an intern for our project, please read our
information for interns.
Costa Rican Birds
Costa Rica has a wealth of resident birds, along with seasonal migrants from
North America that either migrate through or stay the winter in Tortuguero.
"Checklist to the birds of Tortuguero"
is a compiled listing of birds seen or banded at our station. One intern wrote
about his experiences at the banding station in "A
season of bird monitoring in Costa Rica."
In November 2008, Jared Wolfe and the interns participated in a Bird-a-Thon
in and around the Tortuguero station, including a trip to the Tortuguero National
Park. His account, "Tortuguero
Integrated Bird Monitoring Project Bird-a-Thon", also contains a list
of the species observed during the trip.
