L'infiltration des oiseaux forestiers dans les milieux buissonnants de Corse

Auteur :
MARTIN, J. L.

Description :
The bird faunas of two vegetation gradients ranging from open grassland to high forest were compared in southern France and Corsica. On the whole, species richness is lower (ca 30 %) in Corsica than on the mainland. However, a low bird species richness does not characterize all Corsican habitats. Moreover, the bird communities of Corsican shrubby habitats are closer in their diversity and frequency distribution to mainland bird forest communities than to the bird communities of mainland shrubby habitats. The differences are attributable to a broader habitat use by forest birds which formerly colonized Corsica (i.e. an increased niche breadth).
