Contrast sensitivity (CS) is the ability of the observer to discriminate between adjacent stimuli on the basis of their differences in relative luminosity (contrast) rather than their absolute luminances. In previous studies, using a narrow range of species, birds have been reported to have low contrast detection thresholds relative to mammals and fishes. This was an unexpected finding because birds had been traditionally reported to have excellent visual acuity and color vision. This study… 
The contrast sensitivity function of a small cryptobenthic marine fish.
TLDR
It is concluded that the optokinetic reflex seems to be adapted to process low spatial frequency information from stimuli in the peripheral visual field and show that small marine fish can feature excellent contrast sensitivity at optimal spatial frequency.
Current views on vision in mammals
TLDR
Current views on mammal vision based on two cone pigments and rods are discussed and data on spectral sensitivity peaks that characterize visual pigments in different species and orders are provided, as well as the data on spatial contrast sensitivity.
Electrophysiological measures of temporal resolution, contrast sensitivity and spatial resolving power in sharks
TLDR
It is suggested that sharks have retinal adaptations that enhance contrast sensitivity at the expense of temporal and spatial resolution, which is beneficial for vision in dimly lit and/or low contrast aquatic environments.
Spatial Vision in Birds: Anatomical investigation of spatial resolving power
TLDR
This thesis presents four studies on different aspects of spatial vision in parrots, procellariiform seabirds and birds of prey, and indicates, that single cones, not double cones, mediate the high spatial resolution in the raptor fovea.
High resolution of colour vision, but low contrast sensitivity in a diurnal raptor
TLDR
It is revealed that Harris's hawks have high spatial resolving power for both achromatic and chromatic vision, suggesting the importance of colour vision for foraging, and similar to other bird species, Harris's hawk have low contrast sensitivity possibly suggesting a trade-off with chromatic sensitivity.
Chromatic and achromatic vision: parameter choice and limitations for reliable model predictions
TLDR
It is suggested that both chromatic and achromatic contrasts in studies of visual ecology should be examined using calibrated model parameters, and a compilation of what is currently known on visual thresholds and corresponding noise estimates is provided.
Anatomical investigation of spatial resolving power
TLDR
This thesis presents four studies on different aspects of spatial vision in parrots, procellariiform seabirds and birds of prey, and indicates, that single cones, not double cones, mediate the high spatial resolution in the raptor fovea.
Disparity sensitivity in man and owl: Psychophysical evidence for equivalent perception of shape-from-stereo.
TLDR
This study characterized for the first time the spatial disparity-contrast sensitivity function in a non-human species, viz. the barn owl, and discovered a close relationship between the owl and human ability to detect shape-from-stereo.
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

Life-Span Changes in the Visual Acuity and Retina in Birds
TLDR
A series of anatomical, behavioral and electrophysiological studies on pigeons and Japanese quail, investigating life-span changes in cellular components of the retina in birds of known visual acuity, are described.
Visual sensitivity of ground squirrels to spatial and temporal luminance variations
TLDR
The results show that ground squirrels are maximally sensitive to lights flickering at a rate of about 18 Hz, and that the highest rates that are still discriminable are slightly above 60 Hz.
Contrast sensitivity in pigeons: a comparison of behavioral and pattern ERG methods
TLDR
The findings suggest that the PERG is an acceptable alternative to behavioral measurement of CS functions, especially in animal psychophysics, if one takes into account the underestimation of CS by the PERg method and the small changes in peak spatial frequency and bandwidth.

TLDR
Visual acuity thresholds for grating targets were determined for three pigeons and it was concluded that, while the fovea serves the lateral field of view, its presence is not necessary to the static acuity characteristics of this system.

TLDR
The acuity of six pigeons was measured in an apparatus that required the birds to make visual discriminations at a distance of 28.75 in (73 cm) from the stimulus targets, and retinal histology revealed shallow, centrally located foveae in the three pigeon breeds used.

Ultraviolet colour perception in European starlings and Japanese quail.
TLDR
A UV 'colour blindness' test is developed, which is given to a passerine and a non-passerine species and concludes that the output of the violet/UV cone is involved in a chromatic colour vision system in these two species.
Four spectral classes of cone in the retinas of birds
TLDR
The retinal spectral sensitivity functions are consistent with the presence of (at least) four types of cone, but indicate as well that many of the cones that are maximally sensitive in the blue and violet likely contain oil droplets that attenuate the deep violet and near uv.
