Sequencing of the complete mitochondrial genome of the common raven Corvus corax (Aves: Corvidae) confirms mitogenome-wide deep lineages and a paraphyletic relationship with the Chihuahuan raven C. cryptoleucus. [PDF]
Previous studies based on single mitochondrial markers have shown that the common raven (Corvus corax) consists of two highly diverged lineages that are hypothesised to have undergone speciation reversal upon secondary contact. Furthermore, common ravens

Vocal recognition of a nest-predator in black grouse [PDF]
Corvids count among the important predators of bird nests. They are vocal animals and one can expect that birds threatened by their predation, such as black grouse, are sensitive to and recognize their calls.

A spatially explicit modeling framework to guide management of subsidized avian predator densities
Anthropogenic resource subsidization across western ecosystems has contributed to widespread increases in generalist avian predators, including common ravens (Corvus corax; hereafter, raven).

Isotopic analysis reveals landscape patterns in the diet of a subsidized predator, the common raven
Anthropogenic subsidies to native predators can have cascading effects on sensitive prey populations, but the spatial mechanisms behind these effects are often unknown.

[The Common raven Corvus corax is an holoartic species, divided into 12 subspecies, three of which are present in Italy. Based on the most recent systematics, the sub-specific attribution of the Italian populations has been discussed.

Threat-sensitive anti-predator defence in precocial wader, the northern lapwing Vanellus vanellus [PDF]
Birds exhibit various forms of anti-predator behaviours to avoid reproductive failure, with mobbing—observation, approach and usually harassment of a predator—being one of the most commonly observed. Here, we investigate patterns of temporal variation in

Efficacy of CPTH-Treated Egg Baits for Removing Ravens
Human-altered landscapes have provided resource subsidies for common ravens (Corvus corax) resulting in a substantial increase in raven abundance and distribution throughout the United States and Canada in the past 25 years.

Background. From the standpoint of studying relationships in the “predatorprey” system, joint vocalizations of predator birds and their potential prey are of particular importance.

Basic blood biochemical parameters of wild common ravens (Corvus corax) [PDF]
Baseline haematological and biochemical blood parameters in healthy wild birds are key to managing wild populations and to saving critically ill individuals. This knowledge is crucial for the care, rehabilitation and the release of birds after treatment in wildlife rescue centres.

Factors affecting the spatial distribution and breeding habitat of an insular cliff-nesting raptor community [PDF]
The specific spatial distribution and habitat association—strongly influenced by environmental factors or competitive interactions—are major issues in ecology and conservation.
