The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.We present an approach for estimating wildlife abundance from unstructured aerial surveys. We combine a spatial model for count data with auxiliary information on detection probability. This framework is intended to be flexible, requiring lower survey costs and less computation time than other alternatives for estimating abundance.
