Crews Mark Eastern Washington Geese In Ongoing Study Of Nesting Declines

OLYMPIA, Washington –-( State biologists and a team of volunteers plan to fit up to a thousand Canada geese with leg bands this month in a study by the Washington Department of Fish and Wildlife (WDFW) of goose population trends in eastern Washington.

Now in its fourth year, the study is designed to develop a better understanding of nesting declines, hunter harvest patterns and the birds’ use of urban and rural habitat, said Mikal Moore, a WDFW waterfowl specialist.

“Goose nesting counts have been declining for over a decade in most rural survey areas, while complaints about urban geese have been rising,” Moore said. “This study will help us determine if urban birds are year-round residents or migratory, and to what extent they are hunted.”

Moore said urban goose numbers can rise dramatically when they do not migrate, or are not exposed to predators, hunting or other factors that normally limit populations. Geese may become habituated to urban areas that are closed to hunting or when people feed them, she said.

The marking project runs June 13 through June 21, when geese are molting and thus unable to fly. WDFW crews will capture, band, and collar the geese, using boats and portable trapping panels at urban and rural locations in or near Wenatchee, Moses Lake, Yakima, the Tri-Cities, Spokane, and Sprague Lake.

The age and sex of each captured goose will be recorded, and all will be marked with numbered aluminum leg bands. Some adult geese also will receive white neck collars with number and letter codes.

Moore asks that waterfowl hunters report leg band information if they harvest a marked goose. Anyone who spots a goose with a white neck collar is asked to report band or collar codes, along with locations and dates, to the U.S. Geological Survey Bird Banding Laboratory at 1-800-327-BAND or online at

To date, biologists have banded 2,523 geese from eight distinct areas in eastern Washington, Moore said. Of that number, 406 were observed with neck collars and 359 marked geese were taken by hunters.

“Several of the band returns came from as far away as northern Alberta and Saskatchewan, although most were local,” Moore said.
