ハシリカッコウ Carpococcyx radiceus

Secretive pheasant-like cuckoo that is more often heard than seen; listen for its dove-like “coo-KOO” song and odd sneeze-like call. Beautiful if seen well: iridescent purple-green wings, long dark tail, finely barred underparts, black head, and pale blue-green face and bill. Forages on the ground, often following ant swarms or Bornean bearded pigs as they flush out potential prey. Favors pristine lowland rainforests, particularly in riverine or swampy areas.
