This study provides the first experimental evidence of the use of visual cues for parent—offspring communication in a nocturnal bird. Received Sep 23; Accepted Oct 5. However, recent studies have provided support for a possible role of visual communication in nocturnal birds. Kilner ; Saino et al. Introduction Parent—offspring communication in altricial birds often depends upon perception of coloured visual signals. Abstract Visual signals are crucial for parent—offspring communication, although their functioning has been neglected for nocturnal birds. We found evidence of parental bias in favour of lighter offspring: Gape coloration can provide parents with information on nestling level of satiation or health e. We then studied whether UV light reflected by the cere of offspring correlates with nestling weight while they are in the nests. Also, control owlets were in better condition than owlets with brightness-reduced mouths during the post-fledging dependence period Penteriani et al. Parents may also respond to changes in chromatic characteristics of the body skin Jourdie et al. We assessed how parents allocated food during the night in relation to a manipulation of ultraviolet UV reflectance of the cere skin above the beak of their offspring. Reflectance of the cere shows a marked peak in the UV part of the spectrum, and location of the UV peak is related to nestling body mass i. Finally, we experimentally assessed how parents allocated food in relation to a manipulation of UV reflectance of the cere of their offspring. Kilner For instance, there is widespread evidence that nestling gape coloration influences parental feeding decisions e. So far, all evidence of parental favouritism based on visual cues have come from studies with diurnal bird species. Indeed, Penteriani et al. UV-reduced nestlings gained more weight during the night than their control siblings. Here, we investigated parental preference for nestling coloration in nocturnal conditions—a question hitherto unexplored—in a nocturnal raptor, the scops owl Otus scops. Here, for the first time, we explored under nocturnal conditions the influence of nestling coloration on parental preferences in a nocturnal predator raptor, the scops owl Otus scops. Sex scops
