Rock Sparrow (Petronia petronia)
Treecreeper (Certhia familiaris)
Heavily streaked sparrow with diagnostic combination of broad, strong supercilium and white spots at end of tail. Bill deep and cone-shaped with yellow to pinkish base. Primary projection very long. End of under tail coverts pale, giving the bird a broadly barred rump. The white pearls on the short tail and the long wings are conspicuous in flight. Adults with yellow throat-patch, although this is often hidden in many postures. Agile flight, much superior to Passer with regards to both speed and maneuverability.
Sound:Large repertoire of calls of which many recalls Passer, but all with a nasal timbre. Main contact call a nasal "peey-u", rising sharply in pitch and then ending one note lower on the last syllable. Recalls alarm call of Serin in timbre. Sometimes given with only the first syllable. Also a short and explosive "pit", and many less distinct calls when interacting.

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.
