Bluethroat

Summer plumage: Males have brown upperparts, underparts have a blue bib with a rufous crescent at the base of the throat, below is a blue bib bordered by black, white and rufous bands across the breast.

The white band is only a narrow line separating the two other colors. Lower breast and belly are white. Flanks are buffy- white and undertail coverts have a reddish base.

Their head is brown, with a conspicuous white eyebrow extending from the forehead to the rear of their eye. Eyes are dark brown. Legs and feet are gray-brown. 

Winter plumage: There are some whitish feathers that invade the blue bib.

Females are different, with broad whitish mustache bordered by narrow black malar stripe. They have a whitish throat and breast, with a band of black spots across the upper breast, like a necklace.

Some may have blue and rufous on the lower breast, but most of them lack these colors.

Juveniles have a spotted brown plumage, giving a scaly look, but have the reddish pattern of adults on the tail, just less extended.

The first winter resembles adult females with buff tips on wing feathers.

Juvenile males have some blue on the sides of the throat.
