“…[15]). In addition, sleep in birds has been implicated in two types of developmental learning, namely filial imprinting in chicken chicks [44][45][46] and song learning in zebra finches [47][48][49][50]. In addition, sleep plays a role in processing auditory memories in adult starlings [51,52 ].…”

“…They develop their songs at an early age by first forming a template of a tutored song, then practicing by imitation and auditory feedback until the song becomes an accurate imitation of the tutor song. By the time of sexual maturity, the song crystallizes, which is characterized by stereotypy [ 102 , 103 , 104 ].…”

Light, Sleep and Performance in Diurnal Birds

Sleep has a multitude of benefits and is generally considered necessary for optimal performance. Disruption of sleep by extended photoperiods, moonlight and artificial light could therefore impair performance in humans and non-human animals alike. Here, we review the evidence for effects of light on sleep and subsequent performance in birds. There is accumulating evidence that exposure to natural and artificial sources of light regulates and suppresses sleep in diurnal birds. Sleep also benefits avian cognitive performance, including during early development. Nevertheless, multiple studies suggest that light can prolong wakefulness in birds without impairing performance. Although there is still limited research on this topic, these results raise intriguing questions about the adaptive value of sleep. Further research into the links between light, sleep and performance, including the underlying mechanisms and consequences for fitness, could shed new light on sleep evolution and urban ecology.

“…Songbirds communicate through singing 39 ; their songs develop early in life by imitation and auditory feedback. By the time of sexual maturity, the songs of many passerines crystallize 40 – 42 . The ability of young songbirds, such as juvenile zebra finches ( Taeniopygia guttata ), to ultimately mimic adult song is a sleep-dependent process 43 , 44 .…”

Sleep maintains optimal brain functioning to facilitate behavioural flexibility while awake. Owing to a historical bias towards research on mammals, we know comparatively little about the role of sleep in facilitating the cognitive abilities of birds. We investigated how sleep deprivation over the full-night (12 h) or half-night (6 h) affects cognitive performance in adult Australian magpies (Cracticus tibicen), relative to that after a night of undisturbed sleep. Each condition was preceded and followed by a baseline and recovery night of sleep, respectively. Prior to each treatment, birds were trained on an associative learning task; on the day after experimental treatment (recovery day), birds were tested on a reversal learning task. To glean whether sleep loss affected song output, we also conducted impromptu song recordings for three days. Ultimately, sleep-deprived magpies were slower to attempt the reversal learning task, less likely to perform and complete the task, and those that did the test performed worse than better-rested birds. We also found that sleep-deprived magpies sang longer yet fewer songs, shifted crepuscular singing to mid-day, and during the post-recovery day, song frequency bandwidth narrowed. These results collectively indicate that sleep loss impairs motivation and cognitive performance, and alters song output, in a social adult songbird.
