Robins will also nest in manmade nest boxes, favouring a design with an open front placed in a sheltered position up to 2 metres (6 ft 7 in) from the ground. [43] Nests are generally composed of moss, leaves and grass, with fine grass, hair and feathers for lining.
Recent research suggests that this species and some other East Asian members of Luscinia should be classified in a new genus, together with the Japanese and Ryūkyū robins. [2] The genus name Larvivora comes from the Neo-Latin larva meaning caterpillar and -vorus meaning eating (vorace to devour), and cyane is Latin for "dark-blue". [3]
The open cup nest is built by the female and is usually placed less than 5 m (16 ft) above the ground in a hole or crevice in a tree trunk. Sometimes the nest will be placed on the ground. The three eggs in the clutch are pale blue, blue-green, olive-green or olive-brown.
Cape robin-chat (at right) feeding a red-chested cuckoo parasite chick. The Cape robin-chats are monogamous and highly territorial nesters. [19] A pair's territory usually comprises some fraction of a hectare, but its extent varies considerably depending on the habitat. [18] The nest site is within 5 feet (regularly 0 – 2 feet) from the ground.
Like all Australian robins, the eastern yellow robin tends to inhabit fairly dark, shaded locations, and is a perch and pounce hunter, typically from a tree trunk, wire, or low branch. Its diet includes a wide range of small creatures, mostly insects .
The flame robin (Petroica phoenicea) is a small passerine bird native to Australia. It is a moderately common resident of the coolest parts of south-eastern Australia, including Tasmania. Like the other two red-breasted Petroica robins—the scarlet robin and the red-capped robin—it is often simply called the robin redbreast.
The Australasian robin family was first introduced in 1888, as a subfamily with the spelling Petroecinae, by the English ornithologist Alfred Newton. [1] Although named after true robins, the Australian robins, along with many other insect-eating birds, were originally classified as flycatchers in a huge family Muscicapidae. [2]
The same nest site may be reused in subsequent years. [32] [41] An old anecdotal record of these birds laying their eggs in the nests of Turdoides babblers has not been supported by later observers. [42] Laboratory studies have demonstrated cyclic changes in the melanin pigmentation of the tissue surrounding the testes. The dark pigmentation is ...
