Field Notes
Description:
More commonly known as an Osprey (but this spotting is within the Seattle city limits). Its breast and belly are mostly white, with some dark streaks. The white extends out the wings, but the primaries, secondaries, and tail feathers are mottled black-and-white. The back is mostly black or dark brown. The head is distinctive with a white crest, a face bisected by a dark eye-stripe, and yellow eyes. While there is much variation, the female tends to have a streakier breast than the male. The Osprey's talons are uniquely adapted for catching and carrying fish: their surfaces are rough, and their toes can be held with three forward and one back, or with two forward and two back, an arrangement seen in owls but not in other diurnal raptors.
Habitat:
Spotted in a dead snag tree at Discovery Park in Seattle, Wa. Ospreys are common near large bodies of water at lower elevations throughout Washington. They generally return to Washington in late March or early April; most of the population leaves in August or September.
Notes:
The Osprey suffered great declines in the past century as a result of DDT and other eggshell-thinning pesticides. Since the ban of DDT in 1972, the Osprey has made, and continues to make, a strong comeback in much of North America. Range expansion into formerly occupied areas has been slow due to their strong philopatry to nesting areas. Artificial nest platforms have significantly increased nesting in many areas. The Breeding Bird Survey has reported a significant increase in the Osprey population in Washington.
