Large ranches in South Texas, such as the ranches owned by the East Foundation, help preserve large continuous tracts of land, but few long-term non-game bird studies exist from the region. To address this gap, non-breeding and breeding bird surveys were conducted on East Foundation properties in South Texas annually from 2010 to 2020 to document species occurrence, richness, and abundance.
