Guatemalan Tyrannulet

A small, stocky, martin-like swallow that has dark upperparts mottled around the hindneck and back, rusty throat with an indistinct partial dark collar, and a paler buffy belly. In flight, rusty rump and white blotches in the tail are distinctive. Pairs and small flocks are residents and partial migrants foraging over open grassland and rivers, often nesting on cliffs, buildings, or bridges. Calls include a high-pitched twittering, especially at colonies. During May to August overlaps with intra-African migrant South African Swallow, which is very similar to Red-throated Swallow, but is larger and bulkier, lacks white in the tail, and has dark breast mottling forming a smudgy collar.

Small nightjar of savanna and grassland with scattered bushes and palmettos. Spends the day roosting cryptically on the ground, but at night may be found beside quiet roads and tracks. Like all nightjars, eyes reflect amber-red in lights. Plumage similar to other nightjars, but note the pale buffy eyebrow, buffy V-shaped stripe on the back, and bold wing spotting. Male has small white tail tip, lacking in female. White spots on male’s tail usually only visible in the hand. Song is high and insectlike, unlikely to draw attention.

A small bird of lowland and foothill forest midstory. Olive upperparts, yellowish-olive below and brighter yellow throat. Note the split yellow eye-ring and bicolored bill, black above and orange below. Similar to Yellow-legged Flycatcher but Olive Flyrobin has a yellow rather than white throat. Also similar to Lemon-bellied Flycatcher but Olive Flyrobin has a distinct eye-ring and is found in forest rather than savanna. Voice, and up-and-down, medium-pitch, whistled song and a thin “tseep” call.
