Short-toed Treecreeper (Certhia brachydactyla)
Merlin (Falco columbarius)
Very 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.

Smallest falcon. Male with slate grey upperparts, and pinkish buff, speckled underparts . Female dark brown above and heavily speckled below. Due to the extensive markings, the underparts give a darker impression than in Kestrel. Tail of female with dark broad bands, tail of male with broad black terminal band. Diffuse facial markings. Short wings. Silhouette similar to Peregrine, but the much faster wing beats are diagnostic. Acrobatic flight with sharp twist and turns when chasing prey. Alternating glides and bursts of wing-beats gives undulating flight.
Sound:Series of harsh "kwik-wik wik". Coarseness similar to Peregrine, but pace much quicker. Female call harsher than male. Lacking the clearer tones and attack of Kestrel.
