AB We studied the medium-term response of the endemic Blue Chaffinch Fringilla teydeateydea to experimental thinning in a Pinus canariensis plantation on the island of Tenerifeduring breeding season. Distance Sampling method was applied to line transects, andhabitat preferences were modelled by means of univariate regression trees. The densitywas 1.70 birds/ha (1.09 to 2.68 95%CI) in thinned areas and 0.56 birds/ha (0.33 to 0.9795%CI) in unthinned areas. The Blue Chaffinch densities peaked in thinned areas wherethe density of trees with Diameter at Breast Height of <25 cmwas between 10.5 and 16.5trees/plot (r = 25 m) and the cover of Adenocarpus shrubs was  82.5%. Thinning hadadded heterogeneity into the stand structure at least in terms of lowering the basal area ofsmall pine trees and increasing the understorey cover of Adenocarpus shrubs, with averagecover being 37.15% in thinned and only 1.40% in unthinned areas.Our results justifythe silvicultural thinning of 2844 hectares of pine plantation on the summit of GranCanaria as a means of increasing the density of the endangered Gran Canaria Blue Chaffinch(Fringilla teydea polatzeki).
