Barred parakeet

The barred parakeet (Bolborhynchus lineola), also known as lineolated parakeet, Catherine parakeet or 'linnies' for short, 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:^[2]

• Bolborhynchus lineola (Cassin 1853)^[2]
  • Bolborhynchus lineola lineola (Cassin 1853)^[2]
  • Bolborhynchus lineola tigrinus (Souance 1856)^[2] – which has more prominent dark stripes^[3]

Description

The barred parakeet is about 16 cm (6.5 in) in length and has a weight of about 42 to 52 grams.^[3] It is mostly green and has black stripes (or bars) over its upper-parts except on the top of the head.^[3] Its lower-parts are olive-green with very dark green stripes on its sides.^[3] The shoulder of its wings are 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.^[3] Its legs are pink.^[3] 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.^[4] Usually, however, there is no discerning trait to differentiate genders and sexing must be done surgically or through blood tests. The two subspecies differ in the prominence of the dark stripes.^[3]

Habitat and status

Their habitat is the forests and mountains up to 2000 m above sea level or so. 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.^[1]

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.^[4]

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 calm dispositions and peculiar postures. Unlike many birds, lineolateds typically rest in a near horizontal position with their heads almost in line with their tails. They are generally very calm birds and typically mumble quietly, and their calls are not high-pitched or piercing to the ear.

Aviculture

Barred parakeets are popular as pets because of their quiet and even-tempered disposition, and also because many colour mutations are available.^[4] Blue, cobalt, turquoise, mauve, lutino, creamino, cinnamon, golden, pied, silver and violet birds are bred in aviculture. Their average lifespan is about 10 years, but individual birds have been known to live up to 15 years. They are talented mimics of human speech.

Common colors are mainly greens (olive, dark), cobalt, turquoise, grey (also known as mauve), and yellow (or lutino). Dilutes are also available, which generally mark the presence of lighter colors and lighter stripes.

One of the most recognizable and entertaining characteristic of barred parakeets is that they enjoy bathing and being misted with water. Barred parakeets notably enjoy these mist baths; they will hang upside down and open their wings eagerly. Pet linnies are also known to have a unique trait of liking to burrow or hide in or under clothing for hours on end and will sometimes fall asleep in their found hiding places.

Learning to talk

Linneolated parakeets are known for their soft chatter and low noise levels making them ideal apartment pets. They can sometimes make louder noises but this is normally due to distress or their food dish running low. These birds are also known for their ability to talk and imitate noises. Not all individuals will speak and normally the male of the species is more vocal but there are ways to increase the chance of a bird learning words or sounds including:

Starting when the birds are young. Normally they learn the most words while they are less than two years old or moved into a new environment.

Using imitation games which start by rewarding the bird after it imitates a noise that the bird is already known to make and then moving on to words or noises once the bird has caught on to the game.

Saying phrases in an excited noise or when the bird is in an excited state.

Having the bird spend time with a bird that is a known talker, especially if it is the same species.

Sometimes they will mimic a specific person’s tone, normally the person they spend the most time with. They might additionally learn to imitate noises that are undesirable for them to repeat. Unwanted vocalizations can be minimised by not rewarding the bird with laughter or attention or redirecting by getting the bird to perform another known trick.^[5]

Food for pets

Pellets are an ideal base for not only lineolated parakeets, but for many other pet birds as well as it contains many of the essential vitamins and nutrients birds need. Seeds should be fed as a branch of the diet but not as a staple, as a seed-based diet can cause obesity, malnutrition, and kidney failure. Green-leaved vegetables such as kale, collard greens, and turnip greens, as well as broccoli, carrot, and cauliflower are readily consumed. Common fruits that are offered include banana, papaya, apple, apricot, and orange. Eggs, scrambled or boiled (along with the shell) are an excellent source of protein and calcium. Hemp, roasted soybeans, potatoes, green peas, strawberries, coconut, pumpkin seed, alfalfa, and sunflower seeds are other foods that are consumable. It is good to offer different foods to keep the diet balanced and it keeps them from getting bored.

Toxic foods

Owners avoid feeding their birds anything high in salt, sugar, and fat. Common toxic foods include avocado and guacamole, caffeine, fruit pits and apple seeds (contain amounts of cyanide), persimmons, onions (prolonged exposure can lead to a blood condition called hemolytic anemia), mushrooms (cause digestion problems and can induce liver failure), dried/uncooked beans (contain hemaglutin, toxic to birds), the stems, vines, and leaves of tomatoes (the actual fruit is fine), and eggplant.
