Photoregulatory functions drive variation in eye coloration across macaque species
Primates, the most colorful mammalian radiation, have previously served as an interesting
model to test the functions and evolutionary drivers of variation in eye color. We assess the …

Preliminary evidence that eye appearance in parrots (Psittaciformes) co-varies with latitude and altitude
E Duran, JO Perea-García, D Piepenbrock… - Scientific Reports, 2024 - nature.com
External eye appearance in avian taxa has been proposed to be driven by social and
ecological functions. Recent research in primates suggests, instead, that, photoprotective …

The difficult challenge of accurately recording iris colour in birds revealed through the lens of specimens of Australia's Spinifex Pigeon (Geophaps plumifera)
Museum collections of birds are a key source of data on the colours of 'soft parts', eg legs,
feet, bill (maxilla, mandible), wattles, periocular skin and, our focus here, the iris of the eye …

Multimodal signalling in manakins: lack of correlated evolution between acoustic, visual and behavioural traits
S Ariznavarreta, AM Campo, V García‐Navas - Ibis, 2024 - Wiley Online Library
Sexual traits, such as visual adornments, sound‐based cues and courtship dances, are
frequently displayed in combination as multimodal signals. Some hypotheses propose that …

Does the diversity of anuran iris patterns have an ecological function or is it just beauty in the eye of the beholder?
Iris patterns in the animal kingdom are incredibly variable, with anurans having some of the
most diverse and intricate patterns. Although the shape and colouration of anuran eyes …

Eye colour is geographically variable in Lesser Roadrunner Geococcyx velox (Wagner, 1836)
All modern avian world taxonomies currently treat Lesser Roadrunner Geococcyx velox as
monotypic. Since its description in 1836, however, five subspecies have been described …
