Visual abilities in two raptors with different ecology
TLDR
Differences in visual acuity, foveal specialization and visual field between Harris's hawks, Parabuteo unicinctus, and black kites, Milvus migrans, may reflect differences in the perceptual demands of their foraging behaviours.
Visual configuration of two species of Falconidae with different foraging ecologies
TLDR
Differences in visual field configurations and foveal characteristics reflect different foraging demands, suggesting that the extraction of visual information is finely tuned to the demands of their foraging tactics.
Visual adaptations of diurnal and nocturnal raptors.
Visual Adaptations in Predatory and Scavenging Diurnal Raptors
TLDR
The diversity of visual system specializations according to the foraging ecology displayed by these birds suggests a complex interplay between visual anatomy and ecology, often unrelatedly of phylogeny.
Olfaction in raptors

TLDR
Evidence that raptors in general have functional olfactory systems that they may use in a range of different contexts is provided and the available evidence suggests that olfaction may be a more important sensory modality in these birds than previously thought.
Eye Size, Fovea, and Foraging Ecology in Accipitriform Raptors
TLDR
The results suggest that the visual system of raptors within the order Accipitriformes may be highly adapted to the foraging strategy, except for the foveal depth, which seems mostly dependent upon the eye size.
Sight or smell: which senses do scavenging raptors use to find food?
TLDR
Olfaction could be the predominant sense in Turkey vultures while olfaction and sight could play an equivalent role in Southern caracaras, and the experiments suggest that both species are able to use olfactory cues for foraging.
Neoptile feathers contribute to outline concealment of precocial chicks
TLDR
The results suggest that thin skin appendages such as neoptile feathers improve camouflage, which is a widespread strategy to increase survival and may apply to many organisms.
Structure and function of the bird fovea
TLDR
This review gives an overview of the cellular composition of the bird fovea, with special regard to Müller glial cells that provide the mechanical stability of the foveal tissue.
Commentary: Defining Raptors and Birds of Prey
TLDR
This work defines raptors as species within orders that evolved from raptorial landbirds (Telluraves) in which most species maintained raptorial lifestyles, and believes that seriemas (Cariamiformes) should also be considered raptors.

Topography and morphology of retinal ganglion cells in Falconiforms: A study on predatory and carrion‐eating birds
TLDR
The topographic distribution of retinal ganglion cells and their cell body size have been studied in five Falconiform species, including predatory and carrion‐eating birds, and an afoveate temporal area is present in chimango, condor, and vulture.
Hawk Eyes I: Diurnal Raptors Differ in Visual Fields and Degree of Eye Movement
TLDR
Between-species differences in visual field configuration in these diurnal raptors are consistent with prey searching strategies and degree of visual obstruction in the environment and variations in the degree of eye movement between species appear associated with foraging strategies.

TLDR
The data demonstrate that higher visual acuity in mammals is associated with: (1) diurnality and (2) predatory habits once the effects of eye size and phylogeny have been statistically controlled.

TLDR
How birds, particularly birds of prey, see is understood by reviewing pertinent anatomy and physiology of the eye, color vision, visual fields, visual acuity, accommodation, and flicker-fusion frequency.

Scaling of visual acuity with body size in mammals and birds
TLDR
Scaling analyses suggest that subjective visual distances for intraspecific social interactions are size dependent, and a positive association between body size and viewing distance has implications for the scaling of coat pattern features.
