Game and Fish Conducts Bald Eagle Survey

The 21st annual mid-winter bald eagle survey was conducted Jan. 12 along an aerial survey route of the Missouri River stretching from Bismarck to the Garrison Dam. Altogether, 43 bald eagles - 30 adults and 13 immature - and one golden eagle were counted.

Each winter biologists nationwide conduct similar surveys to estimate the number of bald eagles wintering in the lower 48 states, said Patrick T. Isakson, nongame biologist for the North Dakota Game and Fish Department. "Each state completes the survey as close to the target date as possible to make certain that birds are not counted twice," he said.

The number of bald eagles wintering in the state depends on the amount of open water and availability of prey - fish and waterfowl. This year's figure is above-average in North Dakota, Isakson said, but down significantly from last year's record of 75. "Most were counted in the Washburn area and along the Garrison Dam, where a large number of ducks and geese are using open water," he said.

Eagles are relatively easy to spot as they prefer to perch in large cottonwood trees along the river. Adult bald eagles have a white head and tail and a dark brown body, while immature bald eagles are brown with irregular white plumage. Golden eagles have a gold cap on their head.
