Prey species increase activity in refugia free of terrestrial predators
The decline of terrestrial predator populations across the globe is altering top-down pressures that drive predator–prey interactions. However, a...

Red-tailed monkeys (Cercopithecus ascanius) prey upon and mob birds in the Issa Valley, western Tanzania
Interactions between monkeys and birds are rarely observed and, consequently, rarely described in the scientific literature. We recorded two...

Playing it by ear: gregarious sparrows recognize and respond to isolated wingbeat sounds and predator-based cues
The ability to detect an incoming attack provides a final opportunity for an animal to avoid predation. In birds, vision is the main sensory mode in...

Auditory performance in bald eagles and red-tailed hawks: a comparative study of hearing in diurnal raptors
Collision with wind turbines is a conservation concern for eagles with population abundance implications. The development of acoustic alerting...

Tolerance and avoidance of urban cover in a southern California suburban raptor community over five decades
We explored nest site placement and re-use relative to ornamental tree usage and urbanization level in a diurnal raptor community in southern...

Disclosing the hidden nucleotide sequences: a journey into DNA barcoding of raptor species in public repositories
BackgroundIn nucleotide public repositories, studies discovered data errors which resulted in incorrect species identification of several accipitrid...

Hunting and Uses of Terrestrial Vertebrates in the Northernmost Region in the Atlantic Forest in Brazil
Many wild vertebrates of the Atlantic Forest have been exploited by human populations, including several endangered species. The practice of hunting...

Diet of Ornate Hawk-Eagle (Spizaetus ornatus)
The Ornate Hawk-Eagle ( Spizaetus ornatus ) is a top predator and inhabits mainly preserved forests. It occurs from Mexico to Argentina and throughout...

Avian Predators in Rangelands
Management of avian predators in western rangelands is uniquely challenging due to differences in managing for/against particular species, management...

The relative sizes of nuclei in the oculomotor complex vary by order and behaviour in birds
Eye movements are a critical component of visually guided behaviours, allowing organisms to scan the environment and bring stimuli of interest to...

Analysis of the Avifauna Structure in the Alpine Belt of the Northwestern Putorana Plateau, Central Siberia
AbstractEcological patterns of the spatial differentiation of bird fauna and populations in the alpine belt of the northwestern Putorana Plateau were...

Skeleton and Skeletal Muscles
The avian skeleton and skeletal muscles have been modified by natural selection over millions of years to meet the demands of flight. Some birds have...

Ophthalmology of Accipitrimorphae, Strigidae, and Falconidae: Hawks, Eagles, Vultures, Owls, Falcons, and Relatives
Birds of prey, also collectively known as raptors, consist of the Falconiformes (falcons and caracaras), Accipitriformes (eagles, buzzards, hawks,...

Raptors of a Neotropical city: diversity and habitat relationships along an urbanization gradient
Urbanization involves changes in landscape terrain, hydrology, and vegetation. These changes allow some wildlife species to thrive in cities while...

Leopard (Panthera pardus) predation on a red-tailed monkey (Cercopithecus ascanius) in the Issa Valley, western Tanzania
Predation is predicted to be an important selection pressure for primates. Evidence for this hypothesis is rare, however, due to the scarcity of...

Seasonal bird diversity of an urban lake with the history of eutrophication and restoration
Long-term biodiversity monitoring studies of restored wetland ecosystems are essential for successful conservation. We studied the bird diversity of...
