Eye Size, Fovea, and Foraging Ecology in Accipitriform Raptors
Brain, Behavior and Evolution, 2017 Birds with larger eyes are predicted to have higher spatial resolution because of their larger retinal image. Raptors are well known for their acute vision, mediated by their deep central fovea. Because foraging strategies may demand specific visual adaptations, eye size and fovea may differ between species with different foraging ecology.

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)
Journal of Anatomy, EarlyView.Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

Medical and Veterinary Entomology, EarlyView.A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

Analysis of skull morphometric characters in diurnal raptors (Accipitriformes and Falconiformes) [PDF]
Ornis Hungarica, 2019 Abstract Diurnal birds of prey (Accipitriformes and Falconiformes) has traditionally been known as comprising a single order. Recently, this classification has been used in the non-taxonomic sense as referring to a convergent group of birds that are largely classified as predatory birds.
