Sixth visit to incipient Caspian tern colony at the abandoned Georgia Pacific mill site at the Port of Bellingham (WA); high counts of 2,345 adults and 764 chicks were observed on the colony this week; the area that is being used by nesting terns is fenced, providing some protection from mammalian predators; some of the terns colonizing this new site are likely from the failed colony at Dungeness Spit, WA, however, resightings of previously banded terns suggest that terns are also coming from colony sites in the Columbia River estuary, San Francisco Bay, Interior Oregon, and the Columbia Plateau; this completes our weekly reporting of field research activities at the Port of Bellingham Caspian tern colony for 2010
