Olive Long-tailed Cuckoo
Cercococcyx olivinus
Dark gray cuckoo with an unusually long tail and barring on the underparts. Found in forest and thick woodland. Shy and retiring, and most easily found by voice. There are two main vocalizations. One is a long series of slurred “treow” calls which become more emphatic. This sometimes leads into the second call type, which is a three-noted “toot twet tow.” Very similar to Dusky Long-tailed Cuckoo, and best separated by voice, but also identified by paler upperparts, narrower barring on the underparts, and paler rufous on the undertail.

Santa Marta Screech-Owl
Megascops gilesi
Small owl restricted to cloud forest in Colombia’s Santa Marta Mountains. Plumage is almost identical to that of Tropical Screech-Owl, with which it was confused until differences in voice were noted. Color is variable and ranges from dull brown to rusty. Typical song is a rapid series of soft notes that rises and then falls in pitch; it is much longer and steadier than the song of Tropical Screech-Owl, which is found in lower and drier parts of the mountains. Regularly encountered in and around El Dorado Nature Reserve.

Variegated Flycatcher
Empidonomus varius
Medium-sized flycatcher commonly found in the canopy and border of forests, woodlands, savannas, and urban areas where it usually perches on exposed branches. Note the complicated head pattern with a black mask and crown, and a broad white eyebrow and mustache. The black crown also has a central yellow patch, which is often concealed. The body is streaky with a cinnamon rump and tail. Similar to Piratic flycatcher, but Variegated Flycatcher is larger and paler, with cinnamon on the tail and rump and with more boldly-marked wings. The call is nasal “pseeeu.”

Brown Trembler
Cinclocerthia ruficauda
A bright-eyed, hefty billed bird of forests and scrublands. Tends to hold its tail cocked up and wings drooped, especially when feeding. Typically appears almost entirely warm brown; dark above and paler below with some gray on head. Gray Trembler lacks the brown hues of Brown Trembler and has some degree of white below. White-breasted Thrasher has largely bright white underparts and a dark red eye (not yellow as in Brown Trembler). Song is a slow jumble of rich whistles and high-pitched sibilant notes. Calls include scattered whistles and harsh scolding notes.
