13  Bird Conservation Regions

In 2023, we had complete survey coverage across one Bird Conservation Region (Figure 13.1).

Bird Conservation Region 17

We obtained results for Bird Conservation Region 17 by compiling and jointly analyzing data from 31 strata.

Field technicians completed 159 of 172 planned surveys (92%) in 2023. Technicians conducted 1851 point counts within the 159 surveyed grid cells between May 23 and July 13. They detected 192 bird species, including 48 priority species.

Bird Conservancy estimated densities and population sizes for 229 species that were detected in any year during which surveys were conducted, 69 of which are priority species. The data yielded robust density estimates (CV < 50%) for 83 species.

Bird Conservancy estimated the proportion of 1 km² grid cells occupied (Ψ, Psi) throughout Bird Conservation Region 17 for 239 species that were detected in any year during which surveys were conducted, 71 of which are priority species. The data yielded robust occupancy estimates (CV < 50%) for 96 species.
