Conspicuous coloration is often seen as the evolutionary consequence of either sexual
selection or warning predators visually about prey defences, although not all conspicuous …

Birds, and especially raptors, are believed to forage mainly using visual cues. Indeed,
raptors (scavengers and predators) have the highest visual acuity known to date. However …

In this study, we assessed eye morphology and retinal topography in two flamingo species,
the Caribbean flamingo (Phoenicopterus ruber) and the Chilean flamingo (P. chilensis). Eye …

La Tierra está repleta de imágenes y texturas, sonidos y vibraciones, olores y sabores,
campos eléctricos y magnéticos. Pero cada individuo está encerrado dentro de su burbuja …

The anatomical and histological features of the foveae in a gull, Larus michahellis, were
investigated combining immunofluorescence and transmission electron microscopy. In an …

Many falcons (Falco spp.) exhibit a distinct dark plumage patch below the eye, termed the
malar stripe. This stripe is hypothesized to reduce the amount of solar glare reflected into the …

The cathode ray tube (CRT) is a common and important tool that has been in use for
decades, with which behavioral and visual neuroscientists deliver specific visual images …

We present a method to analyse visual attention of a bird in flight, that combines motion
capture data with renderings from virtual cameras. We applied it to a small subset of a larger …

We describe for the first time the visual fields of the largest tropical raptor, the Harpy Eagle
(Harpia harpyja), a powerful keystone species that hunts almost exclusively in forested …

Raptor cognition has received limited research attention, despite the importance of
comparative investigations for reconstructing the evolution of complex cognition. Field …
