The barred parakeet (Bolborhynchus lineola), also known as the lineolated parakeet or the Catherine parakeet, is a small parrot found disjunctly in highland forests from southern Mexico to Panama, in the Andes from western Venezuela to southern Peru and Bolivia, the Santa Marta Mountains in Colombia and the Venezuelan Coastal Range. Its plumage is mostly green with multiple black and dark green stripes or bars, and it has a pale-horn coloured beak. The dark stripes vary in prominence between its two subspecies. Several colour mutants are available in aviculture. Taxonomy There are two subspecies of the barred parakeet: Bolborhynchus lineola (Cassin 1853) Bolborhynchus lineola lineola (Cassin 1853) Bolborhynchus lineola tigrinus (Souance 1856) – which has more prominent dark stripes Description The barred parakeet is about 16 cm (6.5 in) in length and has a weight of about 42 to 52 grams. It is mostly green and has black stripes (or bars) over its upper-parts, except on the top of the head. Its lower-parts are olive-green with very dark green stripes on its sides. The shoulder of its wings is black, there is some blue on the under-side of its wings, and its tail is dark green. The irises are dark brown and its beak is horn coloured. Its legs are pink. Juveniles have less-marked dark stripes, which darken with age. Males and females are generally similar in external appearance, but males may sometimes have more marked black stripes than the female. Usually, however, there is no discerning trait to differentiate sex and sexing must be done surgically or through blood tests. The two subspecies differ in the prominence of the dark stripes. Habitat and status Their habitat is the forests and mountains up to an elevation of roughly above sea level. They spend some of their time on the ground, but sleep high in the trees. They are tolerant of cold and have been seen taking snow baths. The barred parakeet has a large population that is thought to be stable. Behavior and breeding There are usually two to four eggs in a clutch, which hatch after about 18–21 days of incubation. Chicks leave the nest at about five weeks after hatching. Lineolated parakeets are found in the wild in groups of six to thirty, although bigger groups (up to 150 birds) are known. They eat fruit, dried and germinated seeds, and insect larvae. Lineolated parakeets are known for their
