Methods
Using presence data from a regional, standardized monitoring protocol,
we developed habitat suitability models using Maxent and conducted niche
overlap analyses using Principal Component Analysis. We used several
covariates that reflected proximity to habitat characteristics, such as
young forest, shrubland, and understory, as well as proximity to
threats, such as development. We also included topographic and climatic
covariates. We used the Guidos software to categorize the spatial
arrangement of young forest, shrubland, and understory vegetation.
