Birds people confuse

Turkey vulture or Black vulture?

Turkey vulture Not stated

No confirmed photo of Black vulture

Black vulture Not stated

Black vulture: grayish-black head, shorter tail, a white patch near the wing tips (seen from below), and wings held nearly horizontal when soaring, with frequent flapping (Missouri). Tennessee and NPS Everglades say the same: black head, white patch at the wing tips, wings held flat. Turkey vulture: red head (adults), two-toned wings held in a V, rarely flaps. Note: juvenile turkey vultures also have dark heads.

Turkey vulture or Eagle?

Turkey vulture Not stated

Eagle Not stated

An eagle holds its wings flat and they are uniformly black; a turkey vulture's are held in a slight V and are two-toned.

Bald eagle or Golden eagle?

Bald eagle Not stated

No confirmed photo of Golden eagle

Golden eagle Not stated

Young bald eagles lack the white head and tail and are often mistaken for golden eagles. Bald eagles have unfeathered lower legs and hold their wings flat when soaring; TWRA says golden eagles have feathered legs, limited white under the wing, and lift the outer wing in a slight V.

Red-tailed hawk or Red-shouldered hawk?

Red-tailed hawk Not stated

No confirmed photo of Red-shouldered hawk

Red-shouldered hawk Not stated

A red-tail's rust-colored, broad, short tail distinguishes it from the smaller red-shouldered hawk (North Carolina). Tennessee: the red-shouldered hawk has a black and white banded tail and appears more uniformly colored.

Northern cardinal or Summer tanager?

Northern cardinal Not stated

Summer tanager Not stated

MDC: the adult male summer tanager is entirely rosy red, slightly darker on wings and tail, and is a summer resident; the adult male northern cardinal has a crest and a black area around its large red bill and is present year-round. TWRA says the summer tanager is the only other all-red songbird in Tennessee.

Photos show typical adults; individuals vary. Never get close to compare.

When birds are active in Maine

Records of birds in Maine peak in April to August. They show when people record birds, not how many there are (about month bars).

If you see one

Official advice from Maine Department of Inland Fisheries and Wildlife:

• Bears: bring in bird feeders and remove food attractants while bears are active (April 1 to November 1). Maine Department of Inland Fisheries and Wildlife
