Western Olivaceous Warbler
Iduna opaca

Turquoise Tanager
Tangara mexicana
Fairly widespread across northern Amazonia. Striking tanager found in the canopy in forest, edges, plantations, and gardens. Mostly seen in pairs or small single-species groups. Depending on the light can look quite dark, but has a mostly blue head and breast with black on the crown and around the bill, and blue flanks with black spots. Upperparts are mostly black with some blue highlights. Yellow belly. The call is a series of fast and high-pitched “psii” notes.

African Piculet
Verreauxia africana
A tiny woodpecker of forest and forest edge, more likely to be mistaken for a crombec than for another species of woodpecker. A squat bird with a round body, a large head, a short, stout bill, and a very short tail. Body is gray overall with greenish wings, white markings around the ears, and orange around the eyes. Males have an orange forehead. Voice is a weak trilling “si-si-si-si-si.”

Ceara Woodcreeper
Xiphorhynchus atlanticus
Small, slim woodcreeper with a thin slightly decurved bill. Found in humid forests, where it regularly follows mixed-species flocks. The rufous-brown body is heavily marked with drop-shaped spots on the breast, head, and back. Separated from Lesser Woodcreeper by range, blurry streaks on belly, and olive-yellow eyering, eyestripe, and throat.
