Plumbeous Black-Tyrant

Scarce arboreal antbird found in cloud forest along the east slope of the Andes. Its brown and buff plumage, facial pattern, and behavior make it much more likely to be confused with a foliage-gleaner than with other antbirds, but note the stout bill with a hooked tip. Found at middle levels of the forest, and usually encountered with mixed-species flocks. Gives a series of about 8 shrill whistles as well as a faster, rising chatter. No overlap with Russet Antshrike, from which this species was recently split.

A tiny, inconspicuous flycatcher that is best told by combination of small size, relatively large bill, and dense scrub habitat. If seen well, note pale buffy spectacles and yellowish wing bars. Almost always heard before seen. Occurs in dense thickets and scrub, particularly in areas with sandy soils; may be found more generally in forest edge and disturbed habitats within its limited range, where it is uncommon but probably overlooked. Voice is a stuttering purr with a distinctive hollow quality, similar to other Poecilotriccus. Told from Slate-headed Tody-Flycatcher by much duller plumage.

Stout shorebird with a stubby bill. Note orange legs, often bright on spring adults. Breeding plumage has bold black-and-white head and breast pattern; nonbreeding has subdued and browner pattern. Bill is bright orange with a dark tip when breeding, dark otherwise. In flight shows bold white wing stripe. Mellow whistled “poo-ee” call quite distinct from call of more slender and "spectacled" Little Ringed Plover. Breeds on sandy and stony substrates from beaches and lakeshores to moorland above treeline. Winters coastally, where often roosts with other small waders such as Dunlin.
