Hawk-Owl (Surnia ulula)
Short-toed Treecreeper (Certhia brachydactyla)
Hawk-like, partly diurnal owl with long tail and barred underparts. Plumage gives black and white impression. White face framed in bold, vertical black stripes. Eyes bright yellow. Wings fairly short, but not rounded. Tail long and graded. Flight pattern hawk-like, with rapid series of bursting wing-beats followed by glides. Often perched in the open, exposed in tree-tops.
Sound:Seldom heard outside breeding ground. Alarm call a sharp, merlin-like "kwitt kwitt kwitt", or "ki-ki-ki". Song a 10 second rapid pulse of shivering notes with a bubbling quality. Rising slightly in pitch and then slowly falling.

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.
