Field notes

  • It is the only bird species entirely endemic to the state of California.
  • The species is highly susceptible to West Nile Virus, which caused a population decline of nearly 50% in the early 2000s.
  • They exhibit complex social behaviors, including 'funerals' where birds gather silently around a deceased flock mate.
  • During the breeding season, they construct massive, domed stick nests that can reach three feet in diameter.
  • To cope with high summer temperatures, they spend much of the day in the shade of oak canopies and pant to dissipate heat.
Habitat
Oak savannas, riparian woodlands, and agricultural areas with scattered large trees.
Range
California's Central Valley, southern Coast Ranges, and adjacent foothills.
