Fundamentals of spatial vision in the barn owl (Tyto alba pratincola) : ocular aberrations, grating acuity, contrast sensitivity, and vernier acuity
TLDR
Optical quality in barn owl eyes is presented in terms of measuring the ocular wavefront aberrations with a standard Tscherning-type wavefront aberrometer under natural viewing conditions and the results suggest that image quality in Barn Owl eyes is excellent.
Visual adaptations of diurnal and nocturnal raptors.
Spatial contrast sensitivity and grating acuity of barn owls.
The eyes of barn owls (Tyto alba pratincola) display very little aberrations, and have thus excellent optical quality. In a series of behavioral experiments, we tested whether this presumably
Analysis of retinal image quality for peripheral vision in humans and pigeons (Columba livia)
TLDR
Astigmatism of the eye for increasing eccentricity is consistently lower then expected theoretically and when compared with humans, demonstrating that the visual optics of the pigeon are more fully corrected for peripheral vision than in humans.
Visual insignificance of the foveal pit: reassessment of foveal hypoplasia as fovea plana.
TLDR
It is shown that a foveal pit is not required for foveAL cone specialization, anatomically or functionally, and this helps to explain the potential for good acuity in the absence of a pit and raises questions about the visual role of the fovea plana.
Comparative neurophysiology of spatial luminance contrast sensitivity
The luminance contrast sensitivity function has been investigated using behavioral and electrophysiological methods in many vertebrate species. Some features are conserved across species as a shape
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.

Falcon visual sensitivity to grating contrast
TLDR
It is reported that the cut-off frequency (a measure of visual acuity) is twice the expected value and is the same for kestrel and human eyes.

Telephoto lens system of falconiform eyes
TLDR
It is shown here that the presence of a spherical depression in the deep fovea of falconiforms may act like the negative lens component in a telephoto lens system or opera glass, thus providing the relatively large images necessary for more complete image reconstruction in a localised region of the retina.
