Many birds see in the ultraviolet (300–400 nm), but there is limited evidence for colour communication (signalling by spectral shape independently of brightness) in this ‘hidden’ waveband. Such data are critical for the understanding of extravagant plumage colours, some of which show considerable UV reflectance. We investigated UV colour vision in female social responses to the male UV/violet ornament in bluethroats, Luscinia s. svecica. In an outdoor aviary at the breeding grounds, 16 females…

Ultraviolet coloration and colours communication in blue tits PARUS CAERULEUS
TLDR
Reflection measurements in wild breeding blue tits revealed a strong sexual dimorphism in UV/blue crown plumage, indicating that blue tits are substantially more sexually dichromatic to blue tit than to human eyes, and structural UV/ blue coloration was correlated between patches, suggesting indirect or direct sexual selection.
Ultraviolet reflectance influences female preference for colourful males in the European serin
TLDR
It is shown that females preferred yellower males and that male attractiveness was lost when the UV colouration was blocked, with either of the UV-blocking techniques used.
Ultraviolet colour variation influences blue tit sex ratios
TLDR
Experimental evidence that females skew the sex ratio of their offspring in response to the ultraviolet plumage ornamentation of their mates is reported, suggesting that chromosomal sex determination may not constrain the sex ratios of multiparous vertebrates.
Plumage Colours and the Eye of the Beholder The Ecology of Colour and its Perception in Birds
TLDR
This work shows that human colour vision is inadequate for judging animal coloration, and that there is much more going on in bird colour signalling than meets the authors' eye.
ULTRAVIOLET REFLECTANCE OF COLOR PATCHES IN Gallotia galloti LIZARDS FROM TENERIFE, CANARY ISLANDS
TLDR
It is concluded that G. galloti are sexually dichromatic in their own visual world and large interindividual differences in the reflectance of blue patches in lizards from the same sex and population are found, most marked in the UV region of the spectrum.
Ultraviolet vision and foraging in terrestrial vertebrates
TLDR
The possible role of UV cues and existing light conditions should be taken into account when food selection of vertebrate animals is studied, particularly, in experiments with artificial food items.
Ultraviolet colour perception in European starlings and Japanese quail.
TLDR
A UV 'colour blindness' test is developed, which is given to a passerine and a non-passerine species and concludes that the output of the violet/UV cone is involved in a chromatic colour vision system in these two species.
Ultraviolet reflectance patterns of male guppies enhance their attractiveness to females
TLDR
It is shown that UV-reflective components of male colour patterns enhance male attractiveness to females and thus may be elaborated through sexual selection.
Ultraviolet reflectance of colored plastic leg bands
-The bright coloration of plastic leg bands used in avian research has been shown to affect the social interactions of birds by augmenting the ornamentation that traditionally mediates intersexual
Extreme ultraviolet sexual dimorphism in jumping spiders (Araneae: Salticidae)
TLDR
This is the first full UV characterization of a salticid spider and the first study to demonstrate an extreme sexual UV dimorphism in jumping spiders, and provides evidence that UV reflectance may comprise important sexual signals in jumping spider.

Bright ultraviolet colouration in the Asian whistling-thrushes (Myiophonus spp.)

TLDR
The first example of nearly pure UV colouration in passerines, the Asian whistling-thrushes (Myiophonus spp.), is presented and the barb-born UV-structure seems to be a modification of the taxonomically widespread ‘spongy structure’ producing blue and violet feather colours.
Colour discrimination of two passerine bird species in the Munsell system
TLDR
The Bluethroat's better hue discrimination in the short wavelength end of the spectrum (violet and blue) may be connected with the fact that this species has a larger proportion of cones sensitive to shorter wavelengths, while in the Yellow Wagtail about 50% of the cones have red or yellow-orange oil droplets transmitting light efficiently only in the long wavelength part of the Spectrum.
On the measurement and classification of colour in studies of animal colour patterns
TLDR
New methods make it practical to measure the colour spectrum of pattern elements (patches) of animals and their visual backgrounds for the conditions under which patch spectra reach the conspecific's, predator's or prey's eyes.
Coloured leg bands affect male mate-guarding behaviour in the bluethroat
TLDR
It is concluded that colour bands affect the trade-off between mate guarding and advertisement behaviour in a way that is consistent with the hypothesis that bands with ornamental colours improve a male's attractiveness.
Ultraviolet vision and mate choice in zebra finches
TLDR
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.
Ultraviolet vision in birds: What is its function?
Sexual Selection and the Mismeasure of Color
TLDR
It is argued that the error in this assumption that birds see color patterns as humans do may well be a major reason that support for various evolutionary hypotheses involving color is an area of controversy, and suggests methods for overcoming the shortcomings of existing studies.
