Cuban Gnatcatcher
Polioptila lembeyei
A small, energetic, gray-and-white bird that tends to waggle its long tail. Typically feeds low in dense scrub. Endemic to Cuba and offshore islands. Calls include a repeated “da-JIP,” a rapid squeaky “ji-ji-ji-ji-ji,” and a more classic gnatcatcher “zheee.” Note white face outlined with a thin black line, which readily distinguishes Cuban from Blue-gray Gnatcatcher.
识别特征
The Cuban gnatcatcher is 10 to 11 cm (3.9 to 4.3 in) long and weighs 4.5 to 5 g (0.16 to 0.18 oz) and is among the smallest members of genus Polioptila. Like most members of the genus, the male is blue-gray above and white below. It has a unique black crescent behind the eye and ear coverts and a long black tail with white outer feathers. The female is similar but paler, and its facial crescent is thinner. The juvenile is olive-gray above and has buffy flanks, a creamy belly, and only a faint facial crescent.

行为
The Cuban gnatcatcher's diet has not been thoroughly documented; it is assumed to be small insects and spiders. It forages actively among the lower branches of vegetation.<p>The Cuban gnatcatcher's breeding season extends from March to July. Its nest is a deep cup constructed by both sexes using hair, vegetable fibers, and small leaves and lined with softer material. It hangs from a fork in a small branch of a spiny bush up to 6.4 m (21 ft) above the ground. The clutch size varies from two to five but is usually three. In a detailed study cited by Atwood et al (2020), 35 of 38 clutches were predated before the young fledged.<p>The Cuban gnatcatcher's song is "a sustained rambling, disorganized series of warbles, whistles and chattering notes" [1].

Lesser Spotted Woodpecker
Dryobates minor
Very small (sparrow-sized) and easily overlooked woodpecker, often encountered foraging quietly on smaller branches and twigs high in the canopy. Note bold white barring on back and wings, whitish underparts with no red blush under tail; male has red crown patch. Varies subtly across range, especially in the coloration and patterning of the breast and belly; more northern birds tend to have paler, less patterned underparts. Inhabits deciduous woodlands, parkland, and larger gardens. Gives high-pitched squeaky calls and long, even drums.
Cozumel Wren
Troglodytes beani
Small brownish wren found only on Cozumel. Rather plain overall, with dark barring on the wings and tail. Lacks white eyebrow. Generally more arboreal than mainland “House Wrens”, occurring in dense brushy woodland throughout the island. Often perches conspicuously when singing, but otherwise fairly secretive. Listen for loud song of chatters and clearer trills, as well as harsh scolding calls.
Itatiaia Spinetail
Asthenes moreirae
Small, plain, long-billed and long-tailed spinetail with a restricted range. Found in bamboo thickets and clearings in montane forests with grass and shrubs where it forages in the understory. Note the rufous chin contrasting with a dull-brown body. The song is a high-pitched ascending and descending trill.
