The rainbow lorikeet has often included the red-collared lorikeet (T. rubritorquis) as a subspecies, but today most major authorities consider it separate. [14] [15] Additionally, a review in 1997 led to the recommendation of splitting off some of the most distinctive taxa from the Lesser Sundas as separate species, these being the scarlet-breasted lorikeet (T. forsteni), the marigold lorikeet ...
The orange-winged amazon (Amazona amazonica) has been introduced to Tenerife in the Canary Islands, where it has been observed successfully hybridizing with a feral scaly-headed parrot (Pionus maximiliani) and also attempting to breed with feral monk parakeet (Myiopsitta monachus) and rose-ringed parakeet (Psittacula krameri), even involving ...
Abnormal behavior of birds in captivity has been found to occur among both domesticated and wild birds. [1] Abnormal behavior can be defined in several ways. Statistically, 'abnormal' is when the occurrence, frequency or intensity of a behaviour varies statistically significantly , either more or less, from the normal value. [ 2 ]
The group consists of the lories and lorikeets. Traditionally, they were considered a separate subfamily ( Loriinae ) from the other subfamily ( Psittacinae ) based on the specialized characteristics, but recent molecular and morphological studies show that the group is positioned in the middle of various other groups.
Bagemihl's research shows that homosexual behavior, not necessarily sex, has been documented in about 500 species as of 1999, ranging from primates to gut worms. [ 2 ] [ 3 ] Homosexuality in animals is seen as controversial by social conservatives because it asserts the naturalness of homosexuality in humans , while others counter that it has ...
This allofeeding behaviour is suggested to be adaptive because the male is indirectly investing in its offspring. [4] The male uses its energy to forage and retrieve food, and to feed the female. [4] This behaviour of the male reduces the nutritional stress of the female, because it reduces the amount of time the female spends foraging. [4]
Loriinae is a subfamily of psittacine birds, one of the six subfamilies that make up the family Psittaculidae.It consists of three tribes, the lories and lorikeets (), the budgerigar (Melopsittacini) and the fig parrots (Cyclopsittini), which are small birds, mostly of bright colors and inhabitants of Oceania and the islands of Southeast Asia.
The yellow wattlebird is Australia's largest honeyeater and an endemic Tasmanian species. A total of 383 species of bird have been recorded living in the wild on the island of Tasmania, nearby islands and islands in Bass Strait. Birds of Macquarie Island are not included in this list. Twelve species are endemic to the island of Tasmania, and most of these are common and widespread. However ...
