Bornean Ground-Cuckoo
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.
Identification
The Bornean ground cuckoo (Carpococcyx radiceus) is a large, terrestrial species of cuckoo in the family Cuculidae. As suggested by its common name, it is endemic to the island of Borneo, being found in the sections belonging to Brunei, Malaysia, and Indonesia. It is restricted to humid forest. It is threatened by habitat loss. It was formerly considered conspecific with the Sumatran ground cuckoo.
Taxonomy
The Bornean ground cuckoo was described as Calobates radiceus by the Dutch zoologist Coenraad Jacob Temminck in 1832 based on a female specimen from Pontianak district in Borneo. In 1840, George Robert Gray established it as the type species of a new genus, Carpococcyx, because Calobates was similar to the fly genus Calobata. Additionally, it is also a junior homonym of the genus Calobates, established by the German naturalist Johann Jacob Kaup in 1829. The specific name, radiceus, is either from the Neo-Latin radius (rod or staff) or radicis (foundation). It is thought to be an error for radiatus or radiosus, with Temminck himself referring to the species by those names in other writings, but the original description does not provide enough evidence to emend the name. Nevertheless, some authorities use radiatus as the specific epithet.

Mountain Scops-Owl
Otus spilocephalus
Small brown owl of hilly and montane broadleaf forests, rarely in parks and gardens. Dark brown above, paler on the underparts and face, with bright yellow eyes. Prominent bright white stripe between back and wings is more contrasting than in other owls in its range. Brows are frosty white, as in larger Collared Scops-Owl, but ear tufts much shorter in Mountain. Song is a long series of soft double hoots, with 5-10 second pauses between each pair of notes.

Mottled Owl
Strix virgata
A common, fairly large owl of tropical lowlands and foothills. Found in forests, woodlands, plantations, gardens, and towns. Roosts during the day at all levels in dense cover of taller trees, but at night it often hunts from low perches such as fence posts and road signs. Note the rounded head, brown eyes framed with whitish crescents on either side of the bill, and overall brown plumage that is streaked below. Varied gruff hoots can suggest a dog barking.

Coiba Spinetail
Cranioleuca dissita
Lives only on Coiba Island off the Pacific coast of Panama, where identification should not be an issue. Look for rusty upperparts and tail, buffy underparts, and pale buffy eyebrow. Occurs in wooded areas with dense vine tangles and thickets, often in pairs. Listen for excited sputtering chatters.
