Sombre Tit

A small, sharp-billed warbler-like bird that is saturated with yellow. Note the yellow underparts, olive-yellow back, and bold white spectacles around the eyes. Found in forest, scrub, gardens, moist woodland, and plantations, usually in hyperactive flocks that can contain many individuals. Often joins mixed flocks with other small birds. Most common call is a high-pitched rising rattle. Song is a quiet, chatty sequence of “chew” notes. Similar to Northern Yellow White-eye, but slightly darker and greener, and usually separated by range and habitat. Also similar to Pale White-eye, but usually separated by range; shows more yellow above the bill, is more richly-colored overall, and prefers moister habitats.

Small, pale plover with broken collar. In breeding plumage, black ear patch is distinctive. Thin black bill separates from other small plovers at all times of year. Also note relatively long, grayish legs. Typically uncommon. Found on sandy beaches on the coast and inland; usually singly or in small loose flocks. Larger numbers gather at key sites after breeding in summer and fall. Quickly darts around searching for invertebrates in the sand.

Rather local large sparrow of foothills and highlands in Chiapas and northern Central America. Found in brushy woodland and edge and overgrown clearings; usually on or near the ground and often in pairs. Like other ground-sparrows, spends most of its time skulking in shady and often dense cover. Head pattern is distinctive: rusty cap, white face with a beady dark eye, and dark sideburn patch.
