In this report we provide the first predictive model of distribution and abundance for goldencheeked warblers that accounts for heterogeneity in detection probabilities and is spatially explicit using field data gathered across the species‟ breeding range. In Chapter 1, we report development of our habitat classifications and sampling framework, methods used during field surveys for warbler presence or non-presence, and the development and accuracy assessment of our distribution models. In Chapter 2, we evaluate habitat classifications predicted by our distribution models and those developed by Diamond (2007), Loomis-Austin (2008), and SWCA (2007). In Chapter 3, we describe methods for collecting abundance data in the field and we report estimates of regional and range-wide warbler population abundances derived from field-based abundance surveys and our distribution model.
