by John Woodcock
Fall migration monitoring began on August 1 and ran continuously until October 26. August was the busiest month on record at the Cape with 2,605 birds banded; an average of 84 birds per day. An invasion of warblers on August 27 occurred so rapidly that we did not have time to close the nets before becoming completely swamped with birds to process. About 300 birds were released un-banded at the nets as we tried to get them closed before capturing even more.
A total of 6,817 individuals of 97 species/forms were banded in the fall of 2005 at Thunder Cape Bird Observatory.
