To focus nest-search efforts on Hispaniola and estimate the extent of the available nesting habitat, we analyzed the environmental characteristics of Black-capped Petrel (Pterodroma hasitata) nesting habitat and modeled suitable habitat on Hispaniola using openly available environmental datasets. Details on the methodology may be found in the associated publication (Satgé et al. 2020, Habitat modelling locates nesting areas of the Endangered Black-capped Petrel Pterodroma hasitata on Hispaniola and identifies habitat loss. Bird Conservation International). Here we share Supplementary Material referenced in the publication: 1) Georeferenced (projected) raster file of habitat suitability for nesting Black-capped Petrels on Hispaniola: - Satgé et al 2020_Nesting habitat suitability raster_Pterodroma hasitata_90x90m_projected.TIF; 2) Maps of habitat suitability for the Black-capped Petrel on Hispaniola for suitability levels > 0.65, and > 0.90: - Satgé et al 2020_Map of habitat suitability_Pterodroma_hasitata_065.PNG - Satgé et al 2020_Map of habitat suitability_Pterodroma_hasitata_090.PNG. FGDC-compliant metadata are available for each set of materials.
