Yellow-billed Cacique

Unmistakable large noisy tern, with a long, thick yellow bill, black crown, three-toned wings (black outer wing, pale middle, and gray inner wing), and a gray tail. Juveniles have a browner crown and wings. Found along large rivers and lakes and seasonally on the coast.

Small buoyant tern. Breeding adult has distinctive dark smoky gray body and contrasting white cheeks (can look like broad white "whiskers" in flight) underneath a black cap. Nonbreeding plumage pale silvery gray overall with a faded shadow of the cap; juvenile has dark-checkered back. Note rather stout bill (albeit thinner than Gull-billed Tern) and square tail; compare to Common, Roseate, and Arctic Terns. Feeds by picking from surface, not splash-diving like typical terns. Common around wetlands, lakes, and rivers.

Small, distinctive nightjar, pale gray overall with dark brown spots. Note the white eyebrow and moustachial stripe. In flight, males exhibit white underwings and undertail and black flight feathers. Found at a precious few open savanna grassland sites with scattered trees, especially those with numerous termite mounds known as earthmound fields.
