There are two recognised subspecies of the greater ground robin: [2] A. s. sclateriana - The nominate subspecies, found in the mountains of the Huon Peninsula. A. s. occidentalis - Found in the Oranje Mountains in central New Guinea. It has browner and more mottled underparts than the nominate subspecies does. [2] [3]
The nest is a neat cup made of bark and grass. Spider webs, feathers, and fur are used for binding or filling, and the outside is decorated by lichen or bits of bark . The nest is generally placed in a tree-fork or hanging vine, a few metres above the ground. A clutch of two eggs is laid.
The Zero Gravity Research Facility was built in 1966 as part of NASA's Centaur upper-stage rocket development program. In order to ensure proper firing and functioning of upper-stage rockets, NASA needed to understand the behavior of fluids (importantly, the liquid gases fueling the rockets), in the reduced gravity where they would fire.
The rufous-tailed scrub robin is a bird of dry open country with bushes and shrubs. It builds its nest a few feet off the ground; there are three to five eggs in a typical clutch. The rufous-tailed scrub robin is larger than the European robin. It has brown upper parts, whitish under parts, and a prominent whitish supercilium and a dark eye-stripe.
The white-browed robin-chat (Cossypha heuglini), also known as Heuglin's robin, [2] is a species of bird in the family Muscicapidae. Found in east, central and southern Africa, [3] its natural habitats include riverine forest and thickets, and it is also found near humans. The IUCN classifies it as a least-concern species.
Nest predation by introduced common starlings is the most common cause of nesting failure for black robins on Rangatira Island, with almost 21% of nests failing due to starlings. Incidents of failure caused by starlings are more common when black robins nest in cavities compared to open nests. [14]
The position of the red-capped robin is unclear; it and its relatives are unrelated to European or American robins, but they appear to be an early offshoot of the songbird infraorder Passerida. The red-capped robin is a predominantly ground-feeding bird, and its prey consists of insects and spiders. Although widespread, it is uncommon in much ...
The western yellow robin (Eopsaltria griseogularis) is a species of bird in the Australasian robin family, Petroicidae, native to Australia. Described by John Gould in 1838, the western yellow robin and its Australian relatives are not closely related to either the European or American robins, but they appear to be an early offshoot of the Passerida group of songbirds.
