Horned Lark (Eremophila alpestris)
Hen Harrier (Circus cyaneus)
Breeding plumage: Yellow face with broad black moustache stripes and black lores. Black forecrown and thin black horns. Black breast band with blunt vertical extension towards throat (sometimes connects to moustache stripes). Black tail with white sides. Juveniles covered in small pale spots with only faint facial markings. May be confused with juvenile Skylark, but note shorter bill and yellowish face of young Shore larks.
Sound:Song a stream of thin and tinkling, squeaking notes with a recurring, drawn, ringing and slightly ascending chirp. Timbre resemblant to Lapland Bunting. Often given from high in the air, being difficult to locate. More hesitantly when given from the ground with a stumbling introduction. Flight call quite similar to Meadow Pipit's "tseep" call, but less anxious.

CCIn all plumages: Glides with wings raised in shallow V. Shows 5 primaries. This makes the wing tip broader than in Pallid- and Montague's Harriers, and the wings seems shorter. (Note that moulting individuals may show only 4 primaries). Male; grey with black primaries, white rump and underparts, and broad black trailing edge to underwing. Note that subadult males may show partly black primaries like Pallid. Female; brown with white rump, barred tail and streaked underparts.
Sound:Mostly heard at breeding ground. Calls with quite soft series of "ke-ke-ke-ke". Also a wailing, squealing whistle, with emphasized first syllable.
