NORTHERN GOSHAWK Pl. 13
Accipiter gentilis

Description
The Northern Goshawk, our largest accipiter, is a breeding resident
in northern and western mountain forests. Wings are long for an
accipiter, rather buteo-like. Tip of folded tail is wedge-shaped.
Sexes are almost alike in plumage, with females separably larger than
males. Juvenile plumage is different from that of adults. Cere is
greenish yellow to yellow. Legs are yellow. On perched birds,
wingtips extend halfway to tail tip. Widespread race atricapillus is
described below.

ADULT: Head is black except for wide white superciliary lines and
whitish throat. Eye color varies from orange to red to mahogany,
darkening with age. Back and upperwing coverts are blue-gray and
average darker on females; they contrast with blackish uppersides of
flight feathers. Underwing coverts and underparts are pale blue-gray
with fine black vermiculations and some vertical black streaking.
Females usually have coarser, darker barring and more vertical black
streaking. Primaries show dusky banding on undersides; secondaries
show, at most, faint banding. Tail is blue-gray, with three or four
incomplete blackish bands. Undertail coverts are white and fluffy.
