摘要: Species–specific habitat preferences, density and species richness of bird communities in Teneriffe (Canary Islands).— Bird distribution abundance are described analyzed Islands). Inter– differences density, diversity shown table 1. Figure 2 shows the main determinants Teneriffe, tables 3 figure show species–specific patterns spatial variation (more detailed for Anthus berthelotii, Fringilla coelebs canariensis, teydea, Parus caeruleus teneriffae, Phylloscopus Regulus Serinus canarius Turdus merula cabrerae). Deeply transformed environments due to human impact (urban habitats, agricultural mosaics, banana plantations) have high densities richness, even higher than those measured native, unmodified habitats such as laurel forests or mature pinewoods. Urban very permeable native fauna, they been occupied by many widespread endemic species/subspecies. Many endemic, well defined subspecies island birds population within untransformed habitats. Density compensation niche expansion is not a common phenomenon avifauna Teneriffe. Nevertheless, all species/subspecies broadening inter–habitat altitudinal Canary Islands.
