About the Western Kingbird
The western kingbird (Tyrannus verticalis) is a large tyrant flycatcher found throughout western North America, as far south as Mexico. Adults are a combination of both gray and yellow plumage, along with crimson feathers that are hidden until courtship or against intruders. Characteristic of kingbird species, the western kingbird is very territorial. Although the western is often misidentified as Cassin's kingbird, Couch's kingbird, or the tropical kingbird due to the yellow coloration, it can be distinguished from these other species through its black, squared tail with white edges.
The breeding habitat is open areas in western North America. The increased presence of trees throughout the Great Plains during the past century due to fire suppression and tree planting facilitated the range expansion of the western kingbird, as well as range expansions of many other species of birds.
Instances of hybridization with the closely related Eastern Kingbird (Tyrannus tyrannus) have been reported. Hybridization between the two species may become more frequent as the expanding range of the Western Kingbird increasingly... Wikipedia →
