Rufous-fronted Antthrush
Formicarius rufifrons
Range-restricted antthrush of river’s-edge habitats and bamboo. Grayish brown, with an orange forehead. Found in successional forest with dense understory, including areas with bamboo or dense heliconia thickets. Listen for its song, a long, rising-falling series of musical whistles. Voice is similar to the slower song of Buff-throated Woodcreeper, but ascends faster in the middle of the song.

Southern Rough-winged Swallow
Stelgidopteryx ruficollis
Plain brownish swallow, common and widespread through the Neotropics. Very similar to Northern Rough-winged Swallow, but look for contrasting pale rump in flight and tawny throat; also, note that ranges only overlap in Central America. Found in open habitats including fields, rivers, and lakes, often in small loose flocks.

Gray Petrel
Procellaria cinerea
An appropriately named chunky petrel, distinctive in its bland coloration and lack of patterning. Silvery gray-brown above, with a white belly and pale throat. Underwing is dark and unmarked. Bill is pale yellowish with dark contours. Simple bicolored coloration separates this species from other petrels, and chunky proportions and stubby-billed profile distinguish it from similar-looking shearwaters. Follows cold-water currents throughout the southern seas, flying rapidly and directly on stiffly-held wings. Breeds on islands in the southern Atlantic, Pacific, and Indian Oceans, favoring steep slopes with ample ground cover.

Roseate Spoonbill
Platalea ajaja
Unique pink wading bird with long, flat, spoon-shaped bill. Adults are mostly pink overall, with scarlet wing patches, orange tail, and bare pale-green head. Immatures are duller than adults but still washed with pale pink. Sometimes mistaken for a flamingo, but note spoonbill's distinctive bill, shorter legs, and shorter neck. Occurs in freshwater and saltwater wetlands from the Gulf Coast of the U.S. through much of South America. Feeds by sifting side-to-side through shallow water. Often in small loose groups, sometimes with other wading birds like storks and herons.
