Short-toed Snake Eagle (Circaetus gallicus)
Short-toed Treecreeper (Certhia brachydactyla)
Only eagle in WP with whitish underparts and dark hood and chest. Underparts variably barred with 2-3 tail-bands, but leaves an overall pale impression. May be confused with Osprey, but outer wing is much broader and carpal patches is absent. Dark individuals may resemble Honey Buzzards, but note 6 fingers and lack of carpal patches. Pale individuals may show pale throat and chest. Soars on flat or marginally raised wings, with hand stretched slightly forward. Tail slender with straight cut end and sharp corners.
Sound:Quite vocal, especially at breeding ground. A wailing "keeeeaaaaaa" with marked register breaks, or a soft "pjuu-pjuu-pjuu". Male purer and more resonant than female.

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.
