Expression of cell markers and transcription factors in the avian retina compared with that in the marmoset retina
- BiologyThe Journal of comparative neurology
- 2021
It is demonstrated that the expression of transcription factors is a defining feature of cell types not only in the retina of mammals but also in the Retinal ganglion cells of birds.
Deep vascular imaging in the eye with flow-enhanced ultrasound
- Biology, MedicinebioRxiv
- 2021
A high-frequency ultrasound technique with flow-enhancement to image deep vascular beds of the eye with a high spatiotemporal resolution is described and generates non-invasive three-dimensional angiographies without the use of contrast agents that is independent of blood flow angles.
CUDA-Optimized real-time rendering of a Foveated Visual System
- Computer ScienceArXiv
- 2020
This paper demonstrates how a GPU, with a CUDA block-wise architecture, can be employed for radially-variant rendering, with opportunities for more complex post-processing to ensure a metameric foveation scheme.
Possible link between brain size and flight mode in birds: Does soaring ease the energetic limitation of the brain?
- BiologyEvolution; international journal of organic evolution
- 2022
Testing the relationship between brain size, flight modes with different energetic costs (flapping and soaring), and migratory behavior, using published data on the whole‐brain mass of 2242 species provides further support for the energetic tradeoff of the brain with flight and migrating movements in birds and advances the idea that a locomotion mode with lower energetic cost could be a driver of encephalization during the evolution of thebrain.
Birefringence Analyses Reveal Differences in Supramolecular Characteristics of Corneal Stromal Collagen Fibrils Between Falconiformes and Strigiformes.
- BiologyIntegrative and comparative biology
- 2021
It is possible that the supraorganizational differences reported in this study may be sources of variation in the visual quality of Falconiformes and Strigiformes.
Raptors observed (1983–2016) in National Chambal Gharial Sanctuary: semi-arid biogeographic region suggestions for parametric studies on ecological continuity in Khathiar-Gir Ecoregion, India

Hawk Eyes I: Diurnal Raptors Differ in Visual Fields and Degree of Eye Movement
- BiologyPloS one
- 2010
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.
Night vision in barn owls: visual acuity and contrast sensitivity under dark adaptation.
- BiologyJournal of vision
- 2012
It is argued that the visual system of barn owls is designed to yield as much visual acuity under low light conditions as possible, thereby sacrificing resolution at photopic conditions.

Specialized photoreceptor composition in the raptor fovea
- BiologyThe Journal of comparative neurology
- 2017
It is concluded that not only double cones, but also single cones may contribute to high‐resolution vision in birds, and that raptors may in fact possess high-resolution tetrachromatic vision in the central fovea.
Eye Shape and Retinal Topography in Owls (Aves: Strigiformes)
- Biology, Environmental ScienceBrain, Behavior and Evolution

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.

Corrigendum: Retinal transcriptome sequencing sheds light on the adaptation to nocturnal and diurnal lifestyles in raptors
- BiologyScientific reports
- 2016
Strong positive selection for low-light vision genes in owls is found, which contributes to their remarkable nocturnal vision and suggests the adaptive evolution of vision genes reflect differentiated activity time and distinct hunting behaviors.
