Spring migration monitoring began on May 1 and ran continuously until June 11. A total of 1900 individuals of 87 species/forms were banded. There were 9 recaptures of birds banded at TCBO in previous years and one foreign recapture of a Blue jay banded in Minnesota the previous fall. A cabin was constructed this July to provide housing for the Program Coordinator and hiw wife (John & Maureen). Among other activities this season feather samples were collected from migratory songbirds to contribute to the project: Population, Structure and Conservation of Neotropical Migrant Birds.
