Lesser Kestrel (Falco naumanni)
Treecreeper (Certhia familiaris)
Easily confused with Kestrel, especially in female and immature plumage. Adult male with clean, grey cheeks, no moustache-stripe and no streaking on crown. Upper wing, greater coverts are grey, contrasting with brick red forewing and back without dark spots. Belly sparsely spotted. Underside of wings paler with less barring than Kestrel, and with more pronounced dark wing tips and trailing edge. This is also more or less visible in females and young birds. Female and young birds has a less stern look than Kestrel, due to more faint facial markings. Mask do not extend behind the eye. Tail slighty shorter than Kestrel, usually with central feathers slightly elongated (rare in Kestrel). Talons pale, not black. Flight light and fast, with shallow wing-beats. Hovers less than Kestrel, but soars on up-winds. Identification of female/immature birds requires a combination of plumage, structural and behavioural (flight action) characters.
Sound:Contact call diagnostic, and quite different from Kestrel. A di- or trisyllabic "che che che", resembling Partridge in timbre, with two first syllables accentuated. Frequently used in colonies an din flocks. Also a Kestrel-like, plaintive trill "vriiiiii".

CCUnmistakable, except in areas where it coexists with Short-toed Treecreeper. Differs from said species in pure white flanks (sub-species macrodactyla has faintly buff flanks but not as marked as in Short-toed), shorter and only moderately curved bill, hind-claw as long as hind-toe and "notched" wing-bar (uneven "steps"). Tips of primaries with buffish/white tips/fringes extending along inner web. Mostly distinguished from Short-toed by call, and identification exclusively by plumage characters difficult in areas where both species occur.
Sound:Contact call a drawn, high-pitched "tzreeee". Similar to Goldcrest in timbre, but of longer duration with a vibrating and slightly rolling tone. Generally repeated in evenly paced, slow series (unlike Goldcrest). Song a short, continuous three-part phrase. Each phrase starts with a few contact call-like notes followed by a Willow Warbler-like descending part, which then jumps to a few descending high notes to form a marked conclusion. Note that "mixed singers" are not uncommon in areas where both species of treecreepers occur.
