Field notes

  • They possess 'episodic-like memory,' allowing them to remember the specific location, food type, and perishability of thousands of hidden caches.
  • California Scrub-Jays are known to perform 'funerals,' where they gather and vocalize loudly for several minutes around a dead member of their species.
  • They demonstrate tactical deception by re-hiding food if they notice another bird watching them during the initial caching process.
  • Unlike the closely related Steller's Jay or Blue Jay, this species lacks a feathered head crest.
  • They have been observed standing on the backs of mule deer to glean and consume parasitic ticks in a mutualistic relationship.
Habitat
Oak woodlands, chaparral, coastal scrub, and suburban parks or gardens.
Range
Pacific Coast of North America, ranging from southwestern Washington through California to southern Baja California.
