Crested Goshawk calling and preening

on 26th February 2017

According to Wells (1999), the only call recorded locally of the Crested Goshawk (Accipiter trivirgatus) “is a high-pitched, sunbird-like squeak, chiuo, from an anxious captive adult.” Strange (2000) report another call, “a shrill, prolonged scream he-he-he-he-he.”

Jeremiah Loei’s video of the call, although not too audible against the loud background noise, conforms more to Wells’ than to Strange’s.

Most members of the Accipitridae are quite vocal during the breeding season (Thiollay (1994). These vocalisations are associated with reproduction, copulation, brood care, aerial displays, pair bonding, territorial defence and aggression. Outside the breeding season this raptor is usually silent.

The video of preening is shown below.
