SummaryThe schematic eye ofStrix aluco, a nocturnal owl species, is described. A comparative and ecological context is used to examine the relationships between optical parameters of the eye and its light gathering and resolving powers. It is concluded that the essentially ‘nocturnal’ feature of the owl eye does not lie in either its light gathering power or the sensitivity of individual rod receptors. Differences in visual performance at low light levels between the owl and the diurnal pigeon… 

From optics to attention: visual perception in barn owls

Orientation based saliency was demonstrated in a visual-search experiment, and higher cognitive abilities were shown when the owl’s were able to use illusory contours for object discrimination.

Sensory capacities and the nocturnal habit of owls (Strigiformes)

Behavioural studies show that in the eye of the Tawny Owl Strix aluco both absolute visual sensitivity and maximum spatial resolution at low light levels are close to the theoretical limit dictated

Eye Shape and Retinal Topography in Owls (Aves: Strigiformes)

In conclusion, eye shape and retinal topography in owls vary among species and this variation is associated with different activity patterns and habitat preferences, thereby supporting similar observations in other vertebrates.

Through a barn owl’s eyes: interactions between scene content and visual attention

Investigation of visual attention properties of freely behaving barn owls, using a miniature wireless camera attached to their heads, revealed that during an active search task, owls repeatedly and consistently direct their gaze in a way that brings objects of interest to a specific retinal location.

Visual adaptations of diurnal and nocturnal raptors.

Visual fields and their functions in birds

Among birds there are considerable interspecific differences in all aspects of visual fields. However, it is hypothesised that the topography of the frontal binocular portion of fields are of only

What is binocular vision for? A birds' eye view.

It is proposed that with the possible exception of owls, binocularity in birds does not have a higher order function that results in the perception of solidity and relative depth. Rather,

Quantitative estimates of visual performance features in fossil birds

The stringent correlations between avian eyeball morphology and optical function render this system ideal for the analysis of form–function relationships and allow for an accurate estimate of optically significant eyeball soft‐tissue dimensions such as diameter, axial length, and LD in fossil species.

Barn owls (Tyto alba) use accommodation as a distance cue

The results demonstrate that the accommodative effort necessary to fixate the target is one of the parameters by which the owls can estimate distance, at least under monocular viewing conditions.



Absolute visual threshold and scotopic spectral sensitivity in the tawny owl Strix aluco

It is reported that in at least one highly nocturnal owl species, visual sensitivity is only slightly higher than that of man, and that the increased sensitivity can be attributed to optical factors rather than to any increase in sensitivity at the retinal level, suggesting that retinal mechanisms in both man and owl have reached the ultimate in sensitivity for the duplex retinas of terrestrial vertebrates.

Ocular Optical Filtering

The purpose of this chapter is to review the effects of optical filtering on eye function emphasizing such unresolved issues, for example, as the function of optical filters in the eyes of animals with high (suprahuman) visual acuity.

Visual acuity in the tawny owl (Strix aluco).

It is shown that a minimal retinal area in the fovea, which can mediate all the steps in such functions as visual acuity, intensity discrimination, and color vision, contains about 540 cones and certain suggestions with regard to a quantitative mechanism for color vision are correlated with these findings.

A comparative study of deep avian foveas.

Comparisons of foveal cell densities across species showed an increase in the average number of cells/visual degree2 with increasing eye size; similarly, an increase occurred in receptor nuclei relative to ganglion cell density; thus, smaller eyes showed a coarser retinal grain and a lower 'concidence ratio' of receptors toganglion cells than was found in the largest eyes.

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.
