Where is the primary stronghold for breeding Western Kingbirds?

Answer

The interior West, including parts of British Columbia, Alberta, Saskatchewan, and western US states

The core breeding territory for the Western Kingbird is concentrated in the interior western regions of North America. This area stretches extensively from central interior southern British Columbia, Alberta, and Saskatchewan, moving southward through the western United States. Specific states cited as confirmed breeding areas include Utah, Colorado, and Arizona. While they breed patchily eastward across the Great Plains, the highest densities and primary association remain firmly rooted in this western geographical band, requiring birders to focus their search there during the nesting season.
