White-tailed Blue Flycatcher

Distinctive antbird with pale blue eyering and snowy white underparts and rusty upperparts. Black eyebrow and cheek extends through neck sides and down flanks. Occurs in lowland rainforest east of the Andes; no range overlap with similar Bicolored Antbird. Most often seen in the vicinity of army ant swarms, perched on vertical branches or vines close to the ground. Several individuals may gather at a large ant swarm. Listen for harsh descending “churr” calls that might be a clue that there’s an ant swarm nearby.

Plump ground-dwelling dove, quite bright and colorful compared with other quail-doves. Body is grayish, wings are rich brownish-purple, and nape is suffused with iridescent green. Like many quail-doves, face is whiter with dark mustache line, but note buffy forehead. Pinkish-red legs. Sexes alike. Prefers forests, usually on the ground unless flushed up into the lower levels of a tree. Like most quail-doves, often best seen by quietly walking along trails at dawn and dusk.

Massive seabird of warm tropical oceans and coastlines. Overall black with extremely long, deeply forked tail and angular wings. Male completely black with inflatable red pouch on throat (not seen away from breeding colonies) and bluish eyering. In good light, black coloration can show purplish sheen. Adult female has white chest and golden bar on shoulder. Young birds have white head and breast. Often soars for long periods and flies with slow wingbeats. Steals food from other seabirds. Surprisingly acrobatic during aerial chases despite its large size. Limited range overlap with Great Frigatebird (mainly offshore western Mexico and in the Galapagos); identification is complicated by age and sex variation. Adult males are extremely similar; females and immatures best identified by exact pattern of white on head and breast, bill color, and eyering color.
