Horned Lark (Eremophila alpestris)
Short-toed Treecreeper (Certhia brachydactyla)
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.

CCVery similar to Treecreeper C. familiaris, and id by sound generally easier than by appearance in areas where both species occur. Primaries with small, almost pure white tips restricted to outer web. Hind-claw shorter than hind-toe. Wing-bar usually with even "steps", but often difficult to determine. Underparts less white and more brownish than in continental C. familiaris (which again is browner than the pure white northern subspecies). Bill longer and with a stronger curved tip.
Sound:Contact call very similar to C. familiaris. A thin "sreee" often repeated in an even rhythm, perhaps with slighly shorter pauses. Flight call a short and sharp "wit" used freely when moving about. Song diagnostic, and introductory notes often used singly when interacting. Full song starts with one or two staccato introductory notes, the first higher pitched than the second, followed by a rapid, ascending crescendo ending in a drawn-out, less pure "sree". The tone is loud and much more penetrating and clear than C. familiaris. Timbre recalls wet rubber-boots on vinyl flooring. Note that "mixed singers" of C. familiaris are not uncommon in areas where both species of treecreepers occur.
