Buff-sided robin nests are located close to water in dense vegetation, and are established on a horizontal or vertical fork of a tree or shrub, commonly at a height of 1 to 3 m (3.3 to 9.8 ft), [13] [15] [16] [27] and occasionally at greater heights. [31]
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 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 nest is a shallow cup made of bark, grass, and dry leaves. Spider webs are used for binding or filling, and strips of fern and palm for lining; the outside is decorated by dried vegetation. The nest is generally placed in a lawyer vine up to 10 m (30 ft) above the ground. A clutch of one or two eggs is laid.
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 South Island robin is a small passerine, 10–18 cm in length and weighing around 35 g. North Island robins do resemble both females and juveniles of the South Island robins, as well as all the Stewart Island robins, which can sometimes make it difficult to distinguish between the three.
In addition, an examination of reactions that are slowed by low gravity and temperatures will give scientists a deeper understanding of superconductivity. [9] The study of materials science is an important ISS research activity, with the objective of reaping economic benefits through the improvement of techniques used on the ground. [10]
