Sounds and Vocal Behavior

Vocabulary considered to be somewhat limited.

Vocalizations

Vocal Array

Call  (perhaps the song, as it is sometimes given from a treetop) a very characteristic angry hard rattle , tcccccccch, often repeated several or even many times, e.g., chrr-crrk-crrk-crrrrk-crk-crk, similar to the call of Chabert Vanga (Leptopterus chabert) and can be either slower or faster, with the first note usually slightly higher-pitched; also a harsh  teea teea teea or a short, harsh, medium-pitched scheet, which is believed to be given in alarm (1). On the Comoros, C. m. comorensis has a similar vocabulary to that of C. m. madagascarinus, but gives a lower-pitched and harsher craak crkkcrkk, or a ‘coarse frog-like croak’ (23, 24), while the presumed song comprises a grating erch-chhh-crkk-chh-chhh-chhh-crrk, or occasionally a marginally less harsh crew-crew-crew, delivered somewhat haltingly, with the entire sequence lasting 10–30 seconds (1). No information concerning voice of C. m. bensoni (1).
