Raptors have always fascinated mankind, owls for their highly sensitive vision, and eagles
for their high visual acuity. We summarize what is presently known about the eyes as well as …

The cellular structure and functional relevance of the bird fovea are still incompletely
understood. This review gives an overview of the cellular composition of the bird fovea, with …

Birds are renowned for their exceptional vision and the way that this enables them to survive
and navigate the world in such a unique way. However, it is now recognised that avian …

Diurnal raptors (birds of the orders Accipitriformes and Falconiformes), renowned for their
extraordinarily sharp eyesight, have fascinated humans for centuries. The high visual acuity …

Sensory capacities and perceptual challenges faced by gillnet bycatch taxa result from
fundamental physiological limits on vision and constraints arising within underwater …

The turkey vulture (Cathartes aura) is a widespread, scavenging species in the Western
Hemisphere that locates carrion by smell. Scent guided foraging is associated with an …

Despite its prevalence, the importance of scavenging to carnivores is difficult to ascertain in
modern day forms and impossible to study directly in extinct species. Yet, there are certain …

Differences in visual capabilities are known to reflect differences in foraging behaviour even
among closely related species. Among birds, the foraging of diurnal raptors is assumed to …

Birds with larger eyes are predicted to have higher spatial resolution because of their larger
retinal image. Raptors are well known for their acute vision, mediated by their deep central …

Many researchers highlight the role of urban ecology in a rapidly urbanizing world. Despite
the ecological and conservation implications relating to carnivores in cities, our general …
