Very retiring and elusive cuckoo of tropical forest, heard far more often than seen. Sings mainly in spring and summer, and at other times appears absent from areas where it may actually be fairly common. Feeds mostly on the ground, walking stealthily, but usually sings from mid-upper levels in trees, when it is most likely to be seen. Oddly shaped, with small head (rusty crest often raised and lowered) and very long, fan-shaped, (‘pheasant-like’) tail.
