Lories and lorikeets are small to medium-sized arboreal parrots characterized by their specialized brush-tipped tongues for feeding on nectar and soft fruits. The species form a monophyletic group within the parrot family Psittacidae. Traditionally, they were considered one of the two subfamilies in that family (Loriinae), the other being the subfamily Psittacinae, but new insights show that it is placed in the middle of various other groups. To date, this issue has not been resolved scientifically. They are widely distributed throughout the Australasian region, including south-eastern Asia, Polynesia, Papua New Guinea, Timor Leste and Australia, and the majority have very brightly colored plumage.

Morphology[మార్చు]

Tongue of a Lory

Lories and lorikeets have specialized brush-tipped tongues for feeding on nectar and soft fruits. They can feed from the flowers of about 5,000 species of plants and use their specialised tongues to take the nectar. The tip of their tongues have tufts of papillae (extremely fine hairs), which collect nectar and pollen.

Lorikeets have tapered wings and pointed tails that allow them to fly easily and display great agility.[ఆధారం కోరబడినది] They also have strong feet and legs. They tend to be hyperactive and clownish in personality both in captivity and the wild.[ఆధారం కోరబడినది]

Classification[మార్చు]

Traditionally, lories and lorikeets are either classified as the subfamily, Loriinae, or as a family on their own, Loriidae.[1] Neither traditional views is confirmed by molecular studies. Those studies show that the lories and lorikeets form s single group, closely related to the fig parrots (Cyclopsitta and Psittaculirostris) and the budgerigar.[2][3][4][5][6]

Within the lories and lorikeets, two main groups are recognized. The first group consist of the genus Charmosyna[2][3] and the closely related Pacific Ocean genera Phigys and Vini.[2] All remaining genera, except Oreopsittacus are in the second group.[2][3] The position of Oreopsittacus is unknown, although one study suggests it could be a third group next to the other two.[6]

Nomenclature[మార్చు]

The usage of the terms "lory" and "lorikeet" is subjective, like the usage of "parrot" and "parakeet". Species with longer tapering tails are generally referred to as "lorikeets", while species with short blunt tails are generally referred to as "lories".[7]

Conservation[మార్చు]

The Ultramarine Lorikeet is endangered. It is now one of the 50 rarest birds in the world. The Blue Lorikeet is classified as vulnerable. The introduction of European rats to the small island habitats of these birds is a major cause of their endangerment.[8] Various conservation efforts have been made to relocate some of these birds to locations free of predation and habitat destruction.

Colors[మార్చు]

The multi-colored Rainbow Lorikeet was one of the species of parrots appearing in the first edition of The Parrots of the World and also in John Gould's lithographs of the Birds of Australia. Then and now, lories and lorikeets are described as some of the most beautiful species of parrot.

Diet[మార్చు]

In the wild, lorikeets feed on nectar and pollen from plants and flowers. A companion lorikeet however requires a special diet, which makes them less than ideal for a beginner bird owner. A companion bird's diet should consist of a nectar replacement diet, which are available commercially or can be made by the owner. There are two main types of nectar replacement, namely wet mix and dry mix. These mixes come in powder form, the former requires to be mixed with water to create a porridge-like consistency, the latter is to be fed as is. If feeding dry mix, plenty of fresh drinking water needs to be made available for the bird. If the bird is fed on wet mix, their requirements for drinking will be reduced, as the feed contains a large amount of water, however fresh drinking water should still be made available.

Companion lorikeets also need their diet supplemented with fresh fruit and vegetables on a daily basis. A variety of different coloured fruit and vegetables should be made available. A favourite of lorikeets appears to be spinach or silverbeet leaves, and will provide calcium for the bird. Due to the shape of their beak and tongue, rarely will a lorikeet use a cuttlefish for calcium intake. Other kinds of fruit and vegetables frequently enjoyed by lorikeets include apple, pear, corn on the cob, berries, grapes (only feed in small amounts as the high iron content in grapes can cause liver damage), pumpkin, sweet potato, and citrus fruit once a week. Honey is also a favourite of lorikeets, and can be used as a treat or a reward when training a bird.

Do not feed a lorikeet (or any other bird) avocado, onion, chocolate, caffeine or alcohol. These foods contain chemicals which are lethal to a bird.

Due to the largely liquid diet of lorikeets, their droppings are also of a very liquid nature, making them one of the messier companion birds to keep.
