Does year-round territoriality rather than habitat saturation explain delayed natal dispersal and cooperative breeding in the carrion crow?

Carrion Crow (Corvus corone corone) Science Article 4 abstract The ecological factors that promote delayed dispersal of offspring in cooperatively breeding bird species are poorly understood. While single population studies have supported the view that natal dispersal is delayed as a consequence of lack of suitable breeding vacancies (ecological constraints hypothesis), recent theoretical models claim […]

Habitat selection of Hooded and Carrion Crows in the alpine hybrid zone

Carrion Crow (Corvus corone corone) Science Article 3 abstract Habitat selection of co-existing Hooded Crows Corvus corone cornix and Carrion Crows C. c. corone was studied in the Susa valley, an alpine valley in the Iitalian hybrid zone. Foraging habitat use by the two races was not significantly different during the autumn-winter whereas it was […]

Pair composition and reproductive success across a hybrid zone of carrion crows and hooded crows

Carrion Crow (Corvus corone corone) Science Article 2 abstract The Carrion Crow (Corvus corone corone) and the Hooded Crow (C. corone cornix) have parapatric ranges in Europe with narrow areas of hybridization. Reproductive biology of populations of Carrion and Hooded crows and hybrids is described for four areas in northern Italy. Nonrandom mating was observed […]

Reproductive success increases with group size in cooperativecarrion crows, Corvus corone corone

Carrion Crow (Corvus corone corone) Science Article 5 abstract The effect of group size and the number of helpers on reproductive success is crucial to understand theevolution and maintenance of cooperative breeding. In northern Spain, carrion crows form kin-groups(three to nine individuals) where up to five individuals contribute to rearing the young DANIELA CANESTRARI et […]
