Spring migration monitoring began April 27th and ran continuously until June 11th. This was the fifth busiest banding season of 14 spring seasons at the Cape with 2,801 birds banded of 80 species/forms. These figures are somewhat misleading however since two species represent more than 50% of the total catch: 37% of all birds banded were Pine Siskins (1,041 banded) and 17% were Chipping Sparrows (473).
