Common Yellowthroat
Geothlypis trichas
Small warbler, dull olive overall with intense yellow throat. Adult males have black mask bordered above by a white band. Females and immatures are duller but always have contrasting yellow throat and undertail coverts. Common and widespread breeder throughout North America. Found in shrubby wet areas, including marshes, forest edges, and fields. Often hides in thick vegetation, but males often perch conspicuously when singing. Listen for ringing “witchity-witchity-witchity” song and low, harsh call notes. Very short, rounded wings, which equates to it being a short-distance migrant: winters from the southern U.S. to Central America.
识别特征
Common yellowthroats are small songbirds that have olive backs, wings and tails, yellow throats and chests, and white bellies. Adult males have black face masks which stretch from the sides of the neck across the eyes and forehead, which are bordered above with white or gray. Females are similar in appearance, but have paler underparts and lack the black mask. Immature birds are similar in appearance to the adult female. First-year males have a faint black mask which darkens completely by spring.<p>There are 13 races of this bird. These races differ mainly in the males' facial patterns and the brightness of the yellow underparts. The southwestern forms of this bird are the brightest and the yellowest below.<p>Measurements:

Roadside Hawk
Rupornis magnirostris
Well-named, the common roadside hawk in tropical lowlands of East Mexico and Central and South America. Often seen on wires, phone poles, posts out in fields. Adult has staring pale eyes, streaked breast contrasting with barred belly. Immature streaked below, much like many other immature hawks, but its tail has broad and fairly even bands. Flies with rather quick, stiff wingbeats, recalling a Red-shouldered Hawk or an Accipiter; noisy flight display mainly in late winter-spring.
Scarlet-breasted Fruiteater
Pipreola frontalis
Plump, colorful bird of cloud forest along the east slope of the Andes. Plumage is mostly green and yellow, and male has a red throat and breast. Female may have a yellow or orange chin patch, but this feature is often absent on Ecuadorian birds. Female is similar to female Fiery-throated Fruiteater but larger and with an orange (not black) bill. Plucks berries at mid-levels in the forest, and often found in pairs. Gives high-pitched chips and whistles, sometimes followed by a trill.
Cuban Trogon
Priotelus temnurus
A splendid medium-sized inhabitant of woodlands; often found in pairs. Its iridescent blue-green back, smooth gray chest, and brilliant red belly easily distinguish it from all other species in range. Usually sits motionless near the middle level of the forest, but when feeding (typically on flowers and fruit) hovers conspicuously. Often found by its loud calls, which are somewhat varied. One common call is a “cu-cu-cu-cu-cu-cu,” often accelerating; another is a resonant quavering “cu-u-low,” given several times in succession.
