Bird colour vision – from cones to perception
Sign Up to like & getrecommendations! Published in 2019 at "Current Opinion in Behavioral Sciences"
DOI: 10.1016/j.cobeha.2019.05.003
Abstract: Birds use spectral information for circadian control, magnetic orientation and phototaxis but most importantly for discriminating the colours of important objects such as food items or mates. Their tetrachromatic colour vision is based on four… read more here.

DOI: 10.1016/j.heliyon.2017.e00479
Abstract: Extant birds have an extensive spectral range of colour vision among vertebrates, but evidence of colour vision among extinct birds has hitherto been lacking. An exceptionally well-preserved extinct enantiornithine fossil bird from the Early Cretaceous… read more here.

DOI: 10.1016/j.jfo.2020.09.004
Abstract: Given the latest trend in light sources, and in particular, the widespread use of LED lamps, we began to rethink the old lighting standards for colour vision testing. We (J. Leid) therefore conceived a new, easy… read more here.

DOI: 10.1080/13651501.2019.1711421
Abstract: Abstract Background: Abnormalities and contrast sensitivity have already been studied in schizophrenia. However, the relationship between symptom severity in schizophrenia and colour vision sensitivity has not been studied systematically. Aim: Our objective was to evaluate… read more here.

DOI: 10.1093/molbev/msz269
Abstract: The diversity of colour vision systems found in extant vertebrates suggests that different evolutionary selection pressures have driven specialisations in photoreceptor complement and visual pigment spectral tuning appropriate for an animal's behaviour, habitat and life… read more here.

DOI: 10.1098/rstb.2016.0338
Abstract: The evolutionary relationship between signals and animal senses has broad significance, with potential consequences for speciation, and for the efficacy and honesty of biological communication. Here we outline current understanding of the diversity of colour… read more here.

Colour, vision and coevolution in avian brood parasitism
Sign Up to like & getrecommendations! Published in 2017 at "Philosophical Transactions of the Royal Society B: Biological Sciences"
DOI: 10.1098/rstb.2016.0339
Abstract: The coevolutionary interactions between avian brood parasites and their hosts provide a powerful system for investigating the diversity of animal coloration. Specifically, reciprocal selection pressure applied by hosts and brood parasites can give rise to… read more here.

DOI: 10.1098/rstb.2021.0273
Abstract: Colour vision allows animals to use the information contained in the spectrum of light to control important behavioural decisions such as selection of habitats, food or mates. Among arthropods, the largest animal phylum, we find… read more here.
