Abstract: Studies on seabirds nesting in inaccessible areas have benefitted from the advance of species distribution modeling applied over nesting distribution. However, estimation of the effects of potential restoration and / or improvement of breeding habitat has seldom explored using ecological niche modeling. In this study, I applied an ensemble predictive nesting habitat modeling for Trindade Petrel (Pterodroma arminjoniana), an endangered gadfly petrel breeding off a Brazil oceanic island, in order to estimate the nesting area and population size of the species on the Island and test potential effects of vegetation recovery on the nesting habitat of the species. I found that the range of breeding population size estimated by those different models was within the range of the most recent estimations published for this species. The species in its current nesting distribution was only slightly related to the succession stages of vegetation and practically no relation with the remnant forest-like vegetation.
