Formerly known as the Green-backed goldfinch, this species was either not present or overlooked during the 19th century by most Oregon ornithologists. The male's black forecrown contrasts smartly with the greenish back and bright yellow underparts. Females lack the clear contrasting colors of the males, though the tips of the secondary coverts and the base of the primaries are white in both sexes. Often the plaintive tee-yee call reveals the presence of the bird long before it is seen. In the north Willamette Valley the Lesser goldfinch is a fairly common breeder along the western fringe. Scattered and local in…

This sturdy-looking bird has a large head, short tail, and massive conical bill adapted for seed eating. The male plumage features bold patches of lemon yellow shading into olive, then brown and black, with white secondaries creating a flashy wing-patch easily seen in flight. The male's bill is chalky white in winter, but changes in early spring to a pale green that matches the new growth at the tips of spruce boughs, where they often nest. Many encounters with this species are of individuals heard flying high overhead, leaving the observer with little else to note. The Evening grosbeak is…

This large bird of prey is dark above, white below, and has a visible dark spot at the wrist of the wing when flying. The head is black and white. Juveniles have buffy-tipped dark feathers above. In flight, the wings have a noticeable angle or "crook." This highly migratory fish-eating species is frequently found nesting along larger rivers, lakes, and reservoirs. A large bulky nest at the very top of a live, broken top,or dead tree and more recently on utility poles, channel markers, pilings, and cell phone towers near fishable waters is good evidence of Ospreys. The Osprey breed…
