What is the approximate foraging range from the nest during the breeding season?
Answer
At least 400 meters
The scale of the territory required to sustain a breeding pair and their demanding altricial young is substantial, reflecting the high caloric intake needed for their insectivorous diet. During the breeding season, monitoring of foraging activity shows that the Western Kingbird requires and utilizes a feeding territory that extends outward from the nest site for a significant distance. Specifically, the foraging range can extend for at least 400 meters, or approximately 1,300 feet. This large radius underscores why aggressive defense of prime perching spots and surrounding open country is vital for securing a consistent supply of high-protein aerial prey.
