Open-habitat birds in recently burned areas: the role of the fire extent and species’ habitat breadth

Rock Bunting (Emberiza cia) Science Article 1

abstract

Single burned areas contained 0 to 15 open-habitat species (mean = 7.6), and in all the areas combined there were 22 species, including 17 with an unfavourable conservation status in Europe. The most frequent were Carduelis cannabina, Lullula arborea, Alectoris rufa, Oenanthe hispanica and Emberiza cia, but characteristic steppe-land birds such as O. leucura, Calandrella brachydactyla and C. rufescens also bred in particular burned areas. After controlling for the extent of the species range in the Spanish distribution Atlas, passerine occurrence in burned areas was positively related to the species’ habitat breadth in a gradient of unburned habitats. Cluster analysis separated a species-poor group of fire locations from a species-rich group, and showed that some neighbouring areas had a similar species composition.
