Fiery-billed aracari

The fiery-billed aracari or fiery-billed araçari (Pteroglossus frantzii) is a toucan, a near-passerine bird. It breeds only on the Pacific slopes of southern Costa Rica and western Panama. The binomial commemorates the German naturalist Alexander von Frantzius.

Taxonomy and systematics

The fiery-billed aracari is similar to the closely related collared aracari, with which it is sometimes considered conspecific.[2] Frantz's aracari is an alternate name for this species.

Description

Like other toucans, the fiery-billed aracari is brightly marked and has a large bill. The adult is typically 43 cm long and weighs 250 g.

The sexes are alike in appearance, with a black head and chest and dark olive green upperparts, apart from a red rump and upper tail. There is reddish collar on the rear neck. The underparts are bright yellow, with a round black spot in the centre of the breast and a red band across the belly. The thighs are chestnut.

The bare facial skin is black, becoming ruddy behind the yellow eye. The upper mandible of the bill is bright orange, the lower mandible is black, and the legs are green.

Juvenile fiery-billed aracaris are much duller, with sooty-black head and brownish green upperparts. The red rump and yellow underparts are paler, and the breast spot, belly band and bill pattern are indistinct.

It differs from the collared aracari in the orange upper mandible, red belly band, and larger dark breast spot.

The call of the fiery-billed aracari is a loud, sharp pseek, or keeseek, similar to that of collared, but more often two-noted.

Behaviour

Small flocks, usually consisting of up to 10 birds, move through the forest with a rapid direct flight. This species is primarily an arboreal fruit-eater, but will also take insects, lizards, eggs, and other small prey.

Reproduction

The fiery-billed aracari is a common resident breeder in lowland forests and clearings. The two white eggs are laid in an old woodpecker nest, 6–30 m high in a tree. Both sexes incubate the eggs for about 16 days, and the toucan chicks remain in the nest after hatching. They are blind and naked at birth, and have short bills and specialised pads on their heels to protect them from the rough floor of the nest. They are fed by both parents, assisted by up to three other adults, probably from a previous brood, and fledge after about 6 weeks, with feeding by the adults continuing for several weeks after leaving the nest.

The aracaris are unusual for toucans in that they roost socially throughout the year, up to five adults and fledged young of this species sleeping in the same hole with their tails folded over their backs.

gollark: I see you like red turtles.

gollark: Actually, you should give me money so I can pay for useful things like an actual domain for my website.
gollark: I mean, you were going to spend it on discord nitro a few minutes ago, you're clearly desperate to `consume` and waste it on *something*.
