Fiery-billed Aracari
Pteroglossus frantzii
Aracaris are medium-sized toucans, rather slender and long tailed. Fiery-billed is distinctive: the top half of the bill is bright orange. Also note the red belly band. Most often found in small flocks; favors any sort of forested area including edges and gardens.
识别特征
The fiery-billed aracari is about 45 cm (18 in) long and weighs 225 to 280 g (7.9 to 9.9 oz). Like other toucans, the fiery-billed aracari is brightly marked and has a large bill. The adult's bill has a vertical ivory line at its base. Its mandible is black. Its maxilla is mostly red, with a black culmen, yellow tip, and greenish base. Adults have a black head, neck, and throat with a chestnut collar on the nape. Bare red skin surrounds the eye. Their back is blue-green and their rump is red. Their underparts are bright yellow with a red band across the belly and a black spot in the center of the breast. Their thighs are chestnut. Females differ from males only in having a darker chestnut collar and a shorter bill. Immatures have duller plumage overall; its pattern and that of their bill are indistinct.
分类信息
Major taxonomic systems have long treated the fiery-billed aracari as a species that is closely related to the collared aracari (P. torquatus). At least one 20th century author treated it as a subspecies of the collared aracari.<p>The fiery-billed aracari is monotypic.<p>The species' specific epithet commemorates the German naturalist Alexander von Frantzius.[citation needed]

分布与栖息地
The fiery-billed aracari is found from the Gulf of Nicoya on Costa Rica's Pacific coast south into Panama's western Chiriquí Province. It formerly occurred as far east as Veraguas Province. It inhabits the interior and edges of wet primary and secondary forest. In elevation it mostly ranges from sea level to 1,200 m (3,900 ft) but is occasionally found as high as 1,800 m (5,900 ft).

行为
The fiery-billed aracari is considered a year-round resident throughout its range.<p>Fiery-billed aracaris typically travel in groups of about six or more individuals that sometimes include other toucan species. They also roost communally; several may occupy a cavity overnight.<p>The fiery-billed aracari's diet is mostly fruit but it also feeds on large insects, the eggs and nestlings of other birds, and other small vertebrates. It mostly forages in or close under the canopy but will feed on fruits in the understory. They glean fruit by stretching from a perch, bending, and even hanging upside down.<p>The fiery-billed aracari's breeding season in Costa Rica is January to April and may extend later in Panama. The typical clutch size is two though sometimes more are laid. It typically nests in a woodpecker hole, either abandoned or from which they evict the woodpeckers, and which may be as high as 30 m (100 ft) above the ground. The incubation period and time to fledging are not known. Both parents incubate the eggs and provision the nestlings and fledglings. They are often helped by one or more other adults that may be from the previous season's brood. Young nestlings are fed mostly insects.<p>The fiery-billed aracari's calls include high pitched "'pseep' to 'sis-sik' in series" that are essentially the same as those of the collared aracari. It also makes "a croaking call, and soft rattle."

Green-throated Mango
Anthracothorax viridigula
Large, dark hummingbird found in coastal regions and along large rivers. Use caution eliminating the more widespread Black-throated Mango, which often occurs in the same habitats; female-plumaged birds in particular may not be safely separable. Found in mangroves, abandoned plantations, swampy forests, and urban areas, often at higher levels in flowering trees, where it feeds on nectar and hawks for tiny flying insects. In proper light, green throat of male is diagnostic. Tail color is useful if bird can be studied at length; Green-throated’s tail is mostly purple, with brownish central tail feathers (tail of Black-throated is more chestnut, but subject to variation depending on light).
Indian Roller
Coracias benghalensis
A brightly colored bird with various shades of blue on the wings, tails, and belly that are often more prominent in flight. Note the longitudinal white streaks on the throat and breast. Indochinese Roller has a purple-blue breast, a darker olive back, and is generally darker blue. Generally silent, but more vocal in breeding season with harsh calls. Prefers open areas, including agricultural landscapes, sitting on exposed perches including electric wires, occasionally pumping its tail slowly. Practically a resident roller with some movements in the western parts of its range.
Brown Prinia
Prinia polychroa
A dull and poorly marked prinia with a strong bill and a long, graduated tail. Light brown above with faint dark streaking. Pale below, sometimes with some dark smudging along the sides of the breast. Found at low and moderate elevations in open dry forest, shrubby areas, and forest or agricultural edges. Can be retiring and difficult to see in dense vegetation. Sings two different song types: a dry rolling trill and a repeated two-syllabled “tulip.” Separated from other prinias by its overall plainness and lack of contrasting head markings.
