Red-legged Partridge (Alectoris rufa)
Lesser Black-backed Gull (Larus fuscus)
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.
