Бурый рогоклюв Corydon sumatranus

Strange-looking bird with predominantly dark plumage, a pale “bib,” and an enormous, deep-set pink bill. Its long body and bulky build makes it seem more like an aberrant roller than a large broadbill. Forages like a roller, frequently making forays from a perch, but much more social, often being encountered in noisy medium-sized groups. Found in forests from lowlands up into the highlands, typically in wetter areas. Gives many different calls, including an ascending series of squeaky notes, as well as mellow single notes and less pleasant-sounding croaks and rattles.
