The written assari ( Pteroglossus inscriptus ) is a species of bird from the toucan family. The species is widespread in the northern half of South America. The IUCN classifies the text assassin as safe ( least concern ). Exact population figures are not available for this species, but it is said to be relatively common. The name written arassari is derived from the irregular black markings on the beak.
There are two subspecies.
Appearance
Adult font assaris reach a body length of 33.0 to 37.0 centimeters. The males of the nominate form reach a wing length between 11.9 and 12.5 centimeters. The beak has a length of 6.80 to 8.87 centimeters. Females tend to be a bit smaller and, more importantly, have a shorter beak. The beak length is 5.90 to 7.90 centimeters.
The males of the nominate form have a completely black head and an equally colored throat. The top of the body is black with a green-bluish tinge. The hull is bright red. The underside of the body is yellow from the breast to the under tail coverts with an individually variable proportion of light cinnamon-colored body parts. These are usually found on the lower chest, the middle of the abdomen is yellowish white. The featherless eye area is turquoise blue and turns into a red towards the ear area. Females differ from males in that their chin, throat, and sides of the neck are colored differently. You are chestnut colored here.
The bill is yellow and black, in the subspecies Pteroglossus inscriptus humboldti the lower bill is completely black. The eyes are red to brownish red. The legs and feet are blue to green or olive green.
Distribution area
The distribution area of the writing rassari are the tropical lowlands in the northern half of South America. The distribution area extends from the northwest of Metas , from Caquetá and the Departamento de Amazonas along the Andes over the east of Ecuador and Peru to the north of Bolivia and in the southwest of the Brazilian Mato Grosso . In an easterly direction, the distribution area extends to the east coast of Brazil . In Brazil, the distribution area extends from the Amazon in the south to Maranhão and Piauí .
Habitat and way of life
The habitat requirements of the written archer have so far only been insufficiently researched. Among other things, it colonizes secondary forest if it borders on primary forests, forests along rivers, palm forests, forest edges and densely vegetated river banks. It is mainly observed in pairs and small groups. The birds look for food mainly in the treetops. Fruits make up a large part of their diet, but they probably also eat insects. In the Peruvian national park Manú , written arassaris have been observed trying to get to the eggs and nestlings of yellow-bridged front-end birds . Attacks on the nests of the red-backed pigeon are also documented. In some places its range of Lettered Aracari is observed is that he in large fruit-bearing trees together with other toucans such as Weißbrusttukanen , Dottertukanen , Krauskopfarassaris and Braunohrarassaris looking for food. In other regions it is described as a bird that avoids the company of other toucan species. Its flight is characterized by short, powerful wing beats and occasional short gliding flights.
The reproductive biology of the writing rassari is largely unexplored. What is certain is that young birds accompany their parent birds over a longer period of time.
Scripture assaris and people
Written arassaris are hunted as a food resource by the indigenous peoples of South America . It is documented that after an individual was shot, the remaining squad of four other written assaris hated the people . They came within three meters of the hunters. This behavior was also shown by the last bird after three more Arassaris of the troop had been killed.
