BAEZ PEREZ, Sael Anoi; PINTADO MARTINEZ, Leyanis  and  HERNANDEZ MARTINEZ, Fernando. Relationship between bird communities and dendrometric variables in Pinus caribaea Morelet var. caribaea W. H. Barret et Golfari plantations in Viñales , Cuba. Rev. mex. de cienc. forestales [online]. 2016, vol.7, n.33, pp.8-19. ISSN 2007-1132.

The association observed between the bird communities and Pinus caribaea var. caribaea plantations leads to expect a correlation with the characteristics of the trees. This gave rise to the study described below with the purpose of evaluating the existing relationship between the height, tree density and the basal area and bird communities. The sampling was carried out in January through May, 2015, using 30 fixed points in circular plots of 25 m of radius for the forestry study. The abundance and richness between plots and months was compared using the Kruskal-Wallis non-parametric range comparison test; Spearman's Rho non-parametric correlation matrix was utilized for the correlation between this last condition and the dasometric variables, and the link between these and the makeup of the species was determined through a canonical correspondence analysis. 41 species of birds belonging to 16 families and 9 orders were detected; of these, the best represented were the order of Passeriformes and the Parulidae family. In the vertical stratification of the vegetation, the middle stratum was the most visited (42 %). The birds were grouped in 21 trophic groups, among which foliage gleaning insectivores stand out, with 12.1 % of the total. A direct relationship is concluded to exist between the richness and abundance of birds and tree density and the basal area, and, to a lesser extent, the tree height average.
