Field notes

  • It possesses the heaviest and most massive bill of any species in the Tyrannus genus, adapted for capturing large insects.
  • Unlike many other kingbirds, this species lacks a bright yellow belly, showing instead a pale, sulfurous wash.
  • They are aggressively territorial and are known to fearlessly chase away much larger predators like hawks and ravens.
  • In the United States, they are highly localized and primarily found in specific sycamore-lined canyons in Arizona and New Mexico.
  • Their diet is primarily insectivorous, but they are opportunistic enough to occasionally consume small lizards and fruit.
Habitat
Arid riparian woodlands, particularly groves of Arizona sycamore, cottonwood, and oak near water.
Range
Western Mexico through the Pacific slope, extending north into southeastern Arizona and southwestern New Mexico.
