A Synthesis of Sleep in Wild Birds

  title={A Synthesis of Sleep in Wild Birds},
  author={Charles J. Amlaner and Nigel J. Ball},
In this synthesis we have attempted to survey and reanalyse the current literature concerning bird sleep. This was achieved by first reviewing present theory describing functions of sleep. Two general models surfaced which encompass many of the specific sleep theories, namely homeostatic and ecological theories. The terminology used to describe sleep and other associated behaviour was organized into an operational hierarchy. We defined loafing behaviour as a general state of immobility. This… 
Functions of Sleep Architecture and the Concept of Protective Fields
  • U. Voss
  • Biology, Psychology
    Reviews in the neurosciences
  • 2004
The author postulates that one function of the non-cyclical succession of sleep stages is the erection and maintenance of a protective field around the sleeper, minimizing the chances for an intruder to enter the field without detection.
Animal sleep: A review of sleep duration across phylogeny
Energy conservation characterizes sleep in sharks
Low metabolic rate and a flat body posture reflect sleep in draughtsboard sharks, whereas eye closure is a poorer indication of sleep, and the idea for the conservation of energy as a function of sleep in these basal vertebrates is supported.
Variation in sleep behaviour and its underlying causes: a study in a free-living blue tit population
The results indicate that sleep patterns are individual-specific traits in blue tits, and it is suggested that the observed sex difference in sleep duration is caused by sexual selection.
The Phasing of Sleep in Animals
To explain the variety of the phasing of sleep is to confront both the reasons for sleep and the principles behind the scheduling of behavior.
The Evolution of Sleep: A Phylogenetic Approach
The electrophysiological hallmarks of mammalian sleep are often used as the ‘‘gold standard’’ for sleep in nonmammals, while sleep in other vertebrate classes has largely been neglected.


Bioenergetic functions of sleep and activity rhythms and their possible relevance to aging.
It is proposed that sleep constitutes a period of dormancy in which energy is conserved to partially offset the increased energy demands of homeothermy and disruptions of circadian rhythms of sleep and wakefulness in humans produce impairments in mood and performance independent of total amounts of sleep obtained.

Sleep in mammals: ecological and constitutional correlates.
The interrelationships between sleep, ecological, and constitutional variables were assessed statistically for 39 mammalian species. Slow-wave sleep is negatively associated with a factor related to
Irrelevant behaviour, information processing and arousal homeostasis
  • J. Delius
  • Psychology, Medicine
    Psychologische Forschung
  • 1970
A new hypothesis on the causal mechanisms underlying irrelevant behaviour is expanded, and it is argued that over-arousal may occur when information handling exceeds the limited channel capacity of the system, with a consequent loss of efficiency.
The First Morning Song of Some Birds of Washington, D. C.; Its Relation to Light
  • H. Allard
  • Environmental Science
    The American Naturalist
  • 1930
The present paper is intended to be more or less supplementary to an earlier historical contribution (1928) dealing with opinions and theories of bird migration from the point of view of light and changes in the seasonal length of day.
Changes in Sleep Pattern After Sleep Deprivation
The total sleep time increased on the first recovery night compared to the baseline, but it decreased significantly on the second and third recovery nights.
Variation in the Morning Awakening Time of Some Birds in South-Central Michigan
There are many papers in the literature on the roosting times and flights of several species, but the present paper deals only with the awakening time of ten species of birds.
Daylength and the Hummingbirds' Use of Time
The temporal aspects involved in attainment of energy balance by a diurnal bird include duration of adequate light for effective foraging, cyclic availability of food, flight time to a food source or successful prey capture, duration of the nocturnal fast, and the daily environmental temperature cycle that will influence the overall energy cost.
