Tetrachromatic colour vision, based on four ‘main’ colours and their combinations, is probably the original colour vision in terrestrial vertebrates. In addition to human visible waveband of light (400–700 nm) and three main colours, it also includes the near ultraviolet part of light spectrum (320–400 nm). The ecological importance of ultraviolet (UV) vision in animals has mainly been studied in the context of intra- and inter-sexual signalling, but recently the importance of UV vision in…

Ultraviolet (UV) light perception by birds: a review
The ability to perceive the near ultraviolet part of the light spectrum (the wavelength 320-400 nm) has been detected in many bird species and the signalling and communication role of the UV perception is very important.
Ultraviolet vision and foraging in dip and plunge diving birds
Evidence of extended UV vision only in gulls (Laridae) is found, and it is more probable that this trait is associated with their terrestrial foraging habits rather than piscivory.
Ultraviolet Vision May be Widespread in Bats
Seven insectivorous species of bats, representing five genera and three families, showed a statistically significant ‘escape-toward-the-light’ behavior when placed in the Y-maze, providing compelling evidence of widespread dim-light UV vision in bats.
Ultraviolet visual sensitivity in three avian lineages: paleognaths, parrots, and passerines
The results suggest ubiquitous ultraviolet SWS1 sensitivity (UVS) in both paleognaths and parrots, including the nocturnal and flightless kakapo (Strigops habroptilus), and in most, but not all, songbird (oscine) lineages, and confirmed violet sensitivity (VS), and preliminary phylogenetic analysis and ancestral character state reconstructions of key spectral tuning sites along theSWS1 opsin based on sequence data.
Retention and losses of ultraviolet-sensitive visual pigments in bats
Ultraviolet (UV)-sensitive visual pigment and its corresponding ability for UV vision was retained in early mammals from their common ancestry with sauropsids. Subsequently, UV-sensitive pigments,
Pygmy owl Glaucidium passerinum and the usage of ultraviolet cues of prey
It is suggested that pygmy owls can detect near UV and use UV to gain information about prey like other diurnal raptors.
Male Attractiveness Is Influenced by UV Wavelengths in a Newt Species but Not in Its Close Relative
Interestingly, male spectral characteristics and female preferences were consistent with the differences in habitat observed between the two species as L. helveticus often breeds in ponds containing more UV blocking compounds, which is the first report of functional UV-based communication in Amphibians.
Spectral shifts of mammalian ultraviolet-sensitive pigments (short wavelength-sensitive opsin 1) are associated with eye length and photic niche evolution
It is discovered that diurnal mammals and species with longer eyes are more likely to have violet- sensitive pigments and less likely to possess UV-sensitive pigments, and ultraviolet pigments are common in mammals.
The fiddler crab Uca mjoebergi uses ultraviolet cues in mate choice but not aggressive interactions


Behavioural evidence for ultraviolet vision in a tetraonid species – foraging experiment with black grouse Tetrao tetrix
Black grouse preferred UV-reflecting berries when UV light was used for illumination, but showed no preference in the absence of UV light, establishes a potential UV sensitivity in this species; such a sensitivity should be considered in behavioural experiments with this species.
Limits to the salience of ultraviolet: lessons from colour vision in bees and birds.
The relative importance of ultraviolet vis à vis other primary colours in trichromatic or tetrachromatic colour spaces is discussed, and it is concluded that ultraviolet is, in most cases, no more important that blue, green or red reflections.
Ultraviolet cues affect the foraging behaviour of blue tits
Behavioural experiments using wild–caught blue tits foraging for cabbage moth and winter moth caterpillars found that the blue tits tended to find the first prey item more quickly when UV cues were present, suggesting that UV vision offers benefits to birds when searching for cryptic prey, despite the prey and backgrounds reflecting relatively little UV.
Ultraviolet colour vision and ornamentation in bluethroats
In 13 of the 16 trials, the female associated most with the NR male, a preference that implies that UV colour vision is used in mate choice by female bluethroats, suggestive of a UV colour cue in age–related mate preferences.
Ultraviolet vision and mate choice in zebra finches
It is found that the ultraviolet is used, and that it probably contributes to hue perception in avian mate-choice decisions, and supports one hypothesized function of avian ultraviolet vision.
The effects of the light environment on prey choice by zebra finches.
The removal of long-wavelength information had a greater influence than the removal of shorter wavelengths, including ultraviolet wavelengths for this foraging task, which has important implications for predator-prey interactions and suggest that future studies of natural foraging should consider variations in the light environment.
Ultraviolet vision in birds: What is its function?
Ultraviolet reflection of berries attracts foraging birds. A laboratory study with redwings (Turdus iliacus) and bilberries (Vaccinium myrtillus)
It is shown, for the first time, that UV wavelengths are used when birds feed on fruit, and inexperienced birds showed no preferences, suggesting that age and/or learning may affect frugivore preference for UV reflectance.
Blue tits are ultraviolet tits
Reflectance spectrophotometry reveals that blue tit plumage shows considerable reflection of UV light, and sexually dichromatic for multiple regions of plumage, including the crest, which has implications for both intra– and interspecific studies of sexual selection.
