The maps below, produced in 2013, show the predicted density across the study area, of the more common bird species. The density estimates were derived primarily from the OBC point count data, with the OBC census plot data used to validate some of the results. The estimates account for differences in detectability of birds among species, observers, habitats, times of day, and season. The estimated densities at point count locations were then interpolated across the entire study area using a geospatial-kriging algorithm.

You can interpret the maps as estimates of the expected density (# of bird pairs per hectare) of each species at any location within the study area. The habitat data used are from about 2008, so any changes in habitat since then (e.g., new developments) will not be reflected in the maps.
