Red-legged Partridge (Alectoris rufa)
Ferruginous Duck (Aythya nyroca)
Resembles Rock Partridge, Chukar and Barbary Partridge, but these can generally be excluded due to little overlap in range. May be confused with Partridge in flight, but note evenly coloured upperparts, larger size and white supercilium. Differs from all other Alectoris by the combination of broad, speckled collar and marked, black eyestripe. The white throat ends much higher than in congeners, and the upperparts are darker and more brownish. The barring on the flanks is less marked, and seems evenly coloured at a distance.
Sound:Song very similar to Chukar and Rock Partridge. Differs from the latter by fuller and deeper tone and timbre, and more even rhythms. Harder to tell from Chukar, but note Red-legged's tendency to end phrases with a di- or trisyllabic "ka-kaaa" or "ka-ka-kaaa" with a drawn and accented last note. Similar rhythm may be heard in Chukar, but then as a main rhythmic motif. Other calls include hoarse, screeching short utterances.

CCShape resembles both diving and dabbling ducks. Characteristic head profile with long bill, long sloping forehead and rather high rear crown (not unlike Pochard). White undertail usually visible also when on the water. Broad, white wing-bars and white underwing conspicous in flight. White undertail separated from white belly by brown band. Male with shining white eyes. Female with brown eye and less bright rufous tones to plumage. Immature similar to female, but with even less rufous. Immatures told from immature Pochard by by darker back, no facial markings and white (not grey) wing-bars. Note that Tufted Duck sometimes have white (but more diffuse) undertail. Beware also of hybrids with Pochard (note bill-pattern).
Sound:Female call similar to female Tufted Duck's "kerr kerr", but thinner and with a strong, peculiar bi-tone. Male display call mostly consists of various short "chk" sounds.
