You Snooze, You Lose Sleep serves restorative and memory functions, but it does not always operate analogously across species. Deferral of sleep may be possible when selection strongly favors the awake. Lesku et al. (p. 1654; see the Perspective by Siegel) show that sleep may be deferred without cost or impairment in pectoral sandpipers. These birds breed collectively in the high Arctic, and male competition is intense. Competing for, and displaying to, females are both physically and… 
Sleep and vigilance linked to melanism in wild barn owls
It is concluded that different strategies of the regulation of brain activity have evolved and are correlated with melanin‐based coloration and Owlets from heavily spotted mothers might invest more in vigilance, thereby possibly increasing associated costs due to sleep fragmentation.
Suppression of Sleep for Mating
On page 1654 of this issue, Lesku et al. (3) show that in one species of bird, those that sleep the least gain an advantage—they produce the most offspring.

Sleeping on the wing
The ability to interface adaptively with the environment despite sleeping very little challenges commonly held views regarding sleep, and therefore serves as a powerful system for examining the functions of sleep and the consequences of its loss.
Shining evolutionary light on human sleep and sleep disorders
Findings from human sleep studies, the ethnographic record, and the ecology and evolution of mammalian sleep are integrated to better understand sleep along the human lineage and in the modern world.
The cost of deep sleep: Environmental influences on sleep regulation are greater for diurnal lemurs.
It is proposed that sleeping site security was an essential component of sleep regulation throughout primate evolution and may have been an important factor associated with the evolution of sleep in early and later hominins.
The social evolution of sleep: sex differences, intragenomic conflicts and clinical pathologies
How relatedness between social partners may modulate sleeping strategies, depending upon whether sleep sacrifice is selfish or altruistic, is investigated and the potential for intragenomic conflict between maternal-origin versus paternal-origin genes regarding an individual's sleeping behaviour is identified.


Migratory Sleeplessness in the White-Crowned Sparrow (Zonotrichia leucophrys gambelii)
Songbirds exhibit an unprecedented capacity to reduce sleep during migration for long periods of time without associated deficits in cognitive function, in direct contrast to the decline in accuracy and responding observed following as little as one night of experimenter-induced sleep restriction in the same birds during the nonmigratory season.
Sleep deprivation impairs precision of waggle dance signaling in honey bees
It is shown that sleep-deprived honey bees (Apis mellifera) exhibit reduced precision when signaling direction information to food sources in their waggle dances, which is expected to reduce the foraging efficiency of nestmates.
Ostriches Sleep like Platypuses
The findings reveal a recurring sequence of steps in the evolution of sleep in which SWS and REM sleep arose from a single heterogeneous state that became temporally segregated into two distinct states, and suggest that forebrain activation during REM sleep is an evolutionarily new feature, presumably involved in performing new sleep functions not found in more basal animals.
Cetacean sleep: An unusual form of mammalian sleep
Daytime micro-naps in a nocturnal migrant: an EEG analysis
Electrophysiological evidence is provided that short episodes of sleep-like daytime behaviour are accompanied by sleep- like changes in brain activity in an avian migrant and part of this physiological brain response manifests itself as unihemispheric sleep, a state during which one brain hemisphere is asleep while the other hemisphere remains essentially awake.
Local sleep homeostasis in the avian brain: convergence of sleep function in mammals and birds?
After staying awake watching David Attenborough's The Life of Birds with only one eye, SWA and the slope of slow waves increased only in the hyperpallium—a primary visual processing region—neurologically connected to the stimulated eye, providing the first electrophysiological evidence for local sleep homeostasis in the avian brain.
Seasonal influences on sleep and executive function in the migratory White-crowned Sparrow (Zonotrichia leucophrys gambelii)
Birds showed dramatic changes in sleep duration across seasons, related to day length and migratory status, whereas duration of sleep in the non-migratory periods was largely influenced by the light-dark cycle.
