Costa Rican Swift

Large antbird, mostly dark olive-brown with black-and-white bars on the chest. Look for the conspicuous white-crested forehead. Both sexes look similar. Found in the understory of humid forest, where it is an obligate ant-swarm follower. The song is a series of slow descending whistles.

A mid-sized, chunky, drably colored babbler. Has a white throat and pale gray underparts, often with some darker olive-brown on the breast. Found in the understory of rainforest at low and middle elevations, usually in pairs. Shy and skulking, and rarely seen unless searched for. Similar to other illadopsises, and best located and distinguished by voice. Visually most similar to Puvel’s Illadopsis, but found in different habitat, slightly smaller, and grayer, less buffy, on the underparts. Paler below than Brown or Pale-breasted Illadopsises. Most often detected by distinctive voice: a series of several whistles in an up then down pattern that is weirdly reminiscent of trying to start a car. 

Massive snipe found in flooded savanna and grasslands where it usually flushes at close range, showing rounded wings and trailing legs. Has a very long broad-based bill. Yellowish head with two large black streaks. Breast and belly are quite pale and heavily streaked, contrasting with the bold rufous and black lines on the back. Usually detected by sound. On the ground sings a nasal mechanical “aga-aga-aga,” whilst in flight produces an eerie “Hori-go, Hori-go”.
