El arasarí crespo (Pteroglossus beauharnaisii) es una especie de tucán sudamericano cuya principal característica es el plumaje rizado de su cabeza. Se le encuentra en las selvas amazónicas de Perú, Brasil y Bolivia.
Hábitat y área de distribución
El área de distribución del arasarí crespo se encuentra en el sudoeste de la cuenca del Amazonas, los ríos Amazonas al norte y el río Madeira conforman sus límites al norte y al este respectivamente. Al sur limita con el río Xingu. Aunque es un ave poco común su avistamiento es común en ciertas localizaciones como la reserva de Tambopata-Candamo en Perú, el parque nacional Noel Kempff en Bolivia y el Parque Estatal de Cristalino cerca de Alta Floresta en Brasil.
Su hábitat natural son los bosques húmedos de las tierras bajas de la cuenca del Amazonas. Es primordialmente frutívoro, pero también puede alimentarse de polluelos de otras aves como el
Características
El arasarí crespo es un tucán de mediano tamaño con un pico relativamente cordo y cola larga. Estos animales alcanzan un tamaño de unos 42 a 46 cm y pesan entre 164 y 280 gramos. El dimorfismo sexual es limitado, las hembras tienen un pico más corto que los machos. El lomo es de color rojo y el resto de la parte trasera es de color verde oscuro. El plumaje del pecho es amarillo y blanco con puntas negras brillantes. Debajo del pecho tiene una banda de color rojo.
La característica más llamativa son las plumas de la parte superior de la cabeza que se encuentran rizadas. La piel alrededor de los ojos es azul y el iris rojo. Al contrario del resto de tucanes el pico superior es más oscurlo que el inferior.
Curl-crested aracari
The curl-crested aracari or curl-crested araçari (Pteroglossus beauharnaisii) is a near-passerine bird in the toucan family Ramphastidae. It is found in Bolivia, Brazil, and Peru.
Taxonomy and systematics
The curl-crested aracari was first described by Johann Georg Wagler in 1831 but the spelling of its specific epithet was not corrected until 2020. It had at times been placed in the monotypic genera Beauharnaisius and Ulocomus.
The curl-crested aracari is monotypic.
Description
The curl-crested aracari is 42 to 46 cm (17 to 18 in) long and weighs 164 to 280 g (5.8 to 9.9 oz). It gains its English name from unique curly, shiny, black feathers on the top of its head and nape; they resemble pieces of plastic or enamel. Males and females are alike except that the female has a shorter bill. Their bill has a brown-orange line at its base. The mandible is ivory becoming orangey at its tip. The maxilla has an orangey culmen and a maroon stripe along its lower part that is wider at the base. Between them the maxilla is green or bluish. It has indistinct ivory colored «teeth» along the tomium. Bare blue skin surrounds their eye, and their cheeks and throat are whitish with black speckles. Their upper back and rump are red and the rest of their upperparts are dark green. Their underparts are yellow with a wide red band across the lower breast. Their undertail coverts can have a red wash. Immatures are a duller version of adults.
Distribution and habitat
The curl-crested aracari is found in the southwestern Amazon Basin south of the Amazon River. Its range extends from northern Peru south of the Marañón River east into western Brazil to the Madeira River and southeast to the Xingu River. From Peru the range also extends south into northern and central Bolivia and into Brazil as far as northern Mato Grosso. It inhabits the interior, clearings, and edges of wet forest both well-drained and swampy. It mostly occurs at elevations below 500 m (1,600 ft) but is found as high as 900 m (3,000 ft) near the Andes.
Behavior
Movement
The curl-crested aracari apparently makes short-distance or local movements but is otherwise a year-round resident.
Feeding
The curl-crested aracari usually forages in groups of up to 12 individuals, and usually in the canopy. It does feed at fruiting bushes near the ground. Its diet has not been detailed but is known to be mostly fruit. Its diet also includes eggs and young of other birds, and it is known to tear apart the nests of yellow-rumped caciques (Cacicus cela) to obtain them.
Breeding
The curl-crested aracari’s breeding season appears to be mostly May to August but it may start earlier and extend longer. Its nest, eggs, and the rest of its breeding biology are not known.
Vocalization
The curl-crested aracari’s calls include series of «deep ‘rrek’ notes, soft ‘rrr’ to hard, even grunting ‘grenk’ notes». It also makes a «softer ‘et-et'» when settling into a roost. Another author adds a «low, raucous ‘cha-cha-cha cha wruh cha–‘.»
Status
The IUCN has assessed the curl-crested aracari as being of Least Concern. It has a large range, but its population size is not known and is believed to be decreasing. No immediate threats have been identified. It occurs in Tambopata National Reserve in Peru. It is hunted, and more data on this species’ biology are essential, in case it becomes necessary to protect it».
