Voice
In a group, birds give a 3-4 note creaking whistle 'kruik, kruik, kruik, kruik', which lasts 2-3 seconds. This call is occasionally followed by a melodious two-note whistle, descending and then ascending: 'whu, weeeeeeee', lasting 2-3 seconds, and sometimes preceded by a metallic 'tong'. Also, a whistled 'kriuuk . . . kriuuk', lasting 0.8-1.5 seconds, is mostly given in flight. Creaking and trilling notes are also uttered. Juveniles give a repeated soft cawing 'wree-eek'.

Subspecies
No subspecies.

Forms a species pair with Piping Crow (Corvus typicus), which it resembles closely in structure. Until recently, both were thought to belong with the "Slender-billed Crow (Corvus enca) complex", but differ from that in their behaviour and vocalizations.

Similar Species
Slender-billed Crow (Corvus enca) which is larger with more massive bill and proportionately longer tail, and can superficially resemble Slender-billed Cicadabird (Edolisoma tenuirostre) when perched.
