Appearance:

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.

Appearance:

Falcon or cuckoo-like, nocturnal bird with long tail and slender, pointed wings. Unmistakable when seen in areas where no other species of nightjars occur, or when singing. Hard to distinguish from Red-necked Nightjar in the field, but smaller size, smaller head compared to body and shorter tail give indications. If plumage is seen clearly, note general tone (grey brown), dark front edge of arm, broader upper wing-bar and small white throat patch.

Sound:

Song unique among birds, but quite similar to Mole cricket. A mechanical, continuous slur, like the sound of a distant motorbike. As opposed to the Mole Cricket, it often "shifts gear" by changing pitch to a note approximately a fourth below the drone. Flight call a peculiar "kew-eek", with a nasal and frog-like timbre.
