Immature Plumages.<\/em><\/strong>\u00a0 Juveniles have black bills and extensive black markings on the upperparts.<\/p>

The head has a gray shadow on the hindcrown, with a blacker auricular spot, and the back of the neck is predominantly black\u2014a wide black half-collar.\u00a0 These markings sometimes appear as two black collars.<\/p>

The wings have thick black bars on the secondary coverts and outer primaries, which contrast with a large white triangle on the trailing edge of the wing.\u00a0 In flight, these markings form a bold black \u201cM\u201d visible at long range.<\/p>

The tail has a pronounced black terminal band.<\/p>

During the first winter, the black markings on the head and wings lighten.\u00a0 First-summer subadult plumage resembles nonbreeding adult, often with traces of the juvenile markings.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
