The thick- nosed parakeets ( Bolborhynchus ) are a genus of the New World parrots . Today the genus contains only three species, all of which occur in Central and South America. In the past, the Egyptian Parakeet and the Lemon Parakeet were added to this genus. However, these are now assigned to the genus Psilopsiagon .
In the ornamental bird attitude especially playing Katharinasittich a role. For decades it was the only species of the thick-nosed parakeet that was kept in human care.
Appearance and behavior
Fat-billed parakeets are small parakeets whose characteristic feature is their thick, laterally distended beak. The tail is tiered and shorter than the wings in all species. Wax skin and eye ring are not feathered. There is no gender dimorphism. They are cave-breeders that not only breed in tree hollows, but also partly in burrows in the ground. To do this, they create corridors up to two meters long, at the end of which there are one or two chambers with a diameter of 20 to 30 centimeters. The clutch comprises four to six eggs. The incubation period is 20 to 23 days. The young birds fledge after six to seven weeks.
species
The three-nosed parakeets are classified as follows:
- Katharinasittich ( B. lineolea )
- Andean Parakeet ( B. orbygnesius )
- Red-fronted Parakeet ( B. ferrugineifrons )
