Microhabitat of Habia rubica (Vieillot) and Trichothraupis melanops (Vieillot) (Aves, Emberizidae, Thraupinae) in an Atlantic Forest, Southern Brazil

This study identifies which variables characterize the microhabitats of Habia rubica (Vieillot, 1817) and Trichothraupis melanops (Vieillot, 1818) and verifies the pattern of abundance of these species in relation to the parameters of microhabitat. Principal components analysis showed the variables of microhabitat more important for each species. The microhabitat of H. rubica was characterized for the middle stratum open and understory unclear, rich in ferns, young trees, herbs and lianes; this species presented higher abundance in places rich in such variables. For T. melanops, the variables more important were understory unclear with ferns, shrubs, young trees, lianes and herbs, large trees and number of trees with bryophytes; the abundance of this species was unrelated with the density of these variables perhaps due to their generalist habits.
