Western Kingbird

A pale grey-headed flycatcher with a bright yellow belly, typically seen perched conspicuously on wires, fence lines or isolated trees in open country, from where it makes short sallying flights to catch insects. It is active by day and highly visible against open habitat, and is especially easy to find in summer on breeding territories in grassland, farmland and open scrub with scattered perches. It can be notably aggressive toward larger birds that approach its nest, which is a good behavioural clue to a nearby nest site.
