Rimatara Reed Warbler

Long-tailed little bird of dry forest and scrub in northwest Mexico. Found as singles, pairs, or family groups, usually foraging at low to middle levels. Breeding plumage male (March–August) has black cap, but other plumages very similar to Blue-gray Gnatcatcher, a common migrant throughout the range of Black-capped. These species best separated by call note: Black-capped has lower and rougher call than mew of Blue-gray. Also note Blue-gray often has a pinkish base to its smaller bill (gray on Black-capped), a more distinct white eyering (face a little more "open" on Black-capped), and a shorter, less strongly graduated tail.

A slim, cool-gray flycatcher with an upright posture, a white eye-ring broken by a dark stripe through the eye, and a short pale eyebrow. Individuals, pairs, and small groups prefer forest edge, dense woodland, and plantations, where they may join mixed-species flocks foraging in the mid-canopy. The species makes sallying flights to catch insects and small vertebrates, returning to a regular perch. The Ashy Flycatcher lacks the white outer tail feathers and horizontal posture of the otherwise similar Gray-Tit Flycatcher.

Large, rare, enigmatic terrestrial cuckoo, typically very difficult to find. Has a long tail, a strong pale bill, and a black crest. Told from regionally-occurring subspecies of Rufous-vented Ground-Cuckoo by its pale loral region and throat. Often attends army-ant swarms, but also often follows herds of peccaries, groups of monkeys, or mixed flocks of birds. The song is deep and hollow, recalling a dove. Also produces bill snaps, possibly mimicking peccaries.
