It is well established that the lunar cycle can affect the behaviour of nocturnal animals, but its potential to have a similar influence on diurnal species has received less research attention. [] Key Result When the moon was above the horizon at dawn, males began singing on average 10 min earlier, if there was a full moon compared with a new moon, resulting in a 67% mean increase in performance period and greater total song output.

Dupont’s Lark males start to sing earlier but reduce song rate on full moon dawns
Moon phase affects the ecology and behaviour of animals and may thus affect both circadian and circannual rhythms. Its influence on nocturnal and dawn bird behaviour is known, but fewer studies have
The effect of variation in moonlight on nocturnal song of a diurnal bird species
TLDR
It is demonstrated that nocturnal songs are from chorusing males during the breeding season exclusively and thatNocturnal song rate increases with lunar illumination, contrasting with previous research on other diurnal species that sing at night.
Seasonal singing of a songbird living near the equator correlates with minimal changes in day length
TLDR
It is shown that the seasonal timing of dawn-song of male silver-beaked tanagers in the equatorial lowland Amazonas was highly regular between years, and was strongly correlated with slight increases in day length, suggesting songbirds can use day length variation to time singing.
More than noise: light, moon phase, and singing behavior in a passerine
TLDR
This study highlights the importance of considering several pollutants along with moon phase to better understand how they influence animal signals, links light at night with birdsong structure, and provides additional evidence of a circa-lunar rhythm of song output.
Seasonal and diurnal variation of vocal behaviour in duetting White-browed Sparrow Weavers
TLDR
The increased singing rate at the time point wake-up, when all birds are present in the territory, suggests that these songs might convey information about territory ownership, group size as well as sex and status of the individuals.
Seasonal patterns of nocturnal singing by ovenbirds and white-throated sparrows
Recent research suggests that many diurnal songbirds also sing at night. The functions of nocturnal singing by diurnally active birds are not well understood. We used automated recorders to record
Addicted to the moon: vocal output and diel pattern of vocal activity in two Neotropical nightjars is related to moon phase
TLDR
This is the first study comparing the vocal behavior of two Neotropical nightjars over different moon phases and shows that the impact of moonlight may differ between species and at a daily scale when analyzing the periods with the highest and lowest illumination.
Seasonal and daily patterns of nocturnal singing in the Field Sparrow (Spizella pusilla)
TLDR
The seasonal pattern of simple and complex songs suggests that they may have a similar function at night and during the day, with simple songs used for inter-sexual interactions and complex Songs used for intrasexual functions Consequently, the role and function of nocturnal song may be more important for reproductive activities than previously assumed.
Nocturnal singing by diurnal birds in a temperate region of central Europe
Most bird species sing by day, with two distinct peaks of vocal activity—around sunrise and sunset. However, even typically diurnal birds also sing during at night what is for them an atypical part

The dawn chorus in the great tit Paras major is directly related to female fertility
TLDR
It is shown here that changes in the duration of male dawn song are closely related to changes in female fertility.
Experimental manipulation of the dawn and dusk chorus in the blackbird Turdus merula
TLDR
Experimental and correlational data demonstrate that both the nutritional state of the male and his mate's fertility affect the timing and intensity of dawn and dusk song in the blackbird (Turdus merula).
Chronobiology by moonlight
TLDR
The ecological and behavioural evidence showing the effect of moonlight on activity is reviewed, the adaptive value of these changes are discussed, and possible mechanisms underlying this effect are described.
Song in the cold is ‘hot’: memory of and preference for sexual signals perceived under thermal challenge
TLDR
Temperature and song activity of Lincoln's sparrows are recorded on a high-elevation meadow, and it is determined that song behaviour is concentrated around the coldest time of the day, at dawn.
Phylogenetic and ecological determinants of the neotropical dawn chorus
TLDR
This is the first comparative study of the dawn chorus in the Neotropics, and it provides the first evidence for foraging strata as the primary determinant of scheduling participation in the sunrise chorus of birds.
Eye size in birds and the timing of song at dawn
TLDR
It is found that songbirds with large eyes started to sing at lower light intensities (and therefore earlier) than species with smaller eyes, and these relationships were stronger when differences in body size were controlled for statistically, and were consistent between two phylogenies.
The twilight zone: ambient light levels trigger activity in primitive ants
TLDR
It is suggested that the reason for restricting the foraging onset to twilight and measuring light intensity to trigger activity is to optimize the trade-off between predation risk and ease of navigation.
Honest advertisement and song output during the dawn chorus of black-capped chickadees
TLDR
The findings suggest the dawn chorus can provide an accurate signal to females of the relative quality of their mate compared to neighboring males.
