Behavioral thermoregulation in chicks: The best nest

Developmental Psychobiology, 1997
The ability of prehomeothermic chicks to thermoregulate behaviorally was studied in chicks with continuous access to heated nests, running wheels, and separate sources of high and low protein. In Experiment 1, cold-reared groups with heated or unheated transparent nests ate the same amount and selected the same dietary fractions, but chicks with heated

First Description of Nest and Nesting Behavior of the Nightingale Wren

The Wilson Bulletin, 2000
Nests and nesting behavior of the Nightingale Wren (Microcerculus marginatus) in Panama are described. Two nests were found at the ends of horizontal burrows in dirt banks, presumably excavated by other species. The nest chambers were lined with dead leaf fragments. Clutch sizes were two and three eggs. Incubation period was 19 or 20 days for one nest,

Prolactin and nesting behavior in phalaropes

General and Comparative Endocrinology, 1967
Abstract Adenohypophyses of male Wilson's phalaropes ( Steganopus tricolor ), collected during the incubation period, contained about 3.5 times as much prolactin as the gland of females of the species. It is suggested that a deficiency in prolactin may be responsible for the absence of incubation and brooding behavior in the females.

Simulation of Nest Assessment Behavior by Ant Scouts

2002
The scouts of Leptothorax albipennis colonies find and assess new nest sites, when their current nests become uninhabitable. Observations of these scouts have suggested that they assess, among other things, the integrity of the internal periphery and the size of the potential nest site.

Unusual Behaviors at a Robin's Nest

The Condor, 1982
Three unusual behaviors were seen at the nest of an American Robin (Turdus migratorius) on the Saint Bonaventure University campus, New York, in the spring of 1980. Once, a spotted young robin incubated eggs of a later brood, and on several occasions recent fledglings begged for food at the nest and received food from the incubating adult female.

A note on pterosaur nesting behavior

Historical Biology, 2007
Based on examination of eggshell structure and predicted vapor conductances in eggshells in recently described material from Argentina and China we conclude that pterosaurs buried their eggs. Egg-burying imposes theoretical restrictions on the distribution of pterosaurs, both geographically and spatially, raises the possibility of thermal sex ...

On the Nesting Behavior of T-splines

2011
Abstract : We establish rigorously the fundamental nesting behavior of T-spline spaces in terms of the topology of the T-mesh. This provides a theoretical foundation for local refinement algorithms based on analysis-suitable T-splines and their use in isogeometric analysis. A key result is a dimension formula for smooth polynomial spline spaces defined
