Aphelocoma californica

Holds funerals. When one dies, nearby jays gather silently for minutes.
- Populasi
- Global population estimated at ~2,480,000 mature individuals (listed under the pre-split name "Western Scrub-jay"), including ~1,990,000 in the USA; trend is decreasing but not steeply enough to affect its conservation status.
- Habitat
- Low-elevation scrub, oak woodlands, pinyon-juniper forest, chaparral, and edges of mixed evergreen forest; also very common in suburban gardens, parks, and backyards
- Fakta menarik
- California Scrub-Jays have been documented picking ticks and other parasites off mule deer, with the deer standing still (even raising their ears) to let the jay work — a rare bird-mammal grooming partnership.
- Sebaran
- Pacific coast of North America, extending from Washington state (with range expansion into southern British Columbia) south through California (west of the Sierra Nevada) and western Nevada near Reno, continuing to Baja California, Mexico; non-migratory, year-round resident throughout
- Makanan
- Omnivorous: acorns and other nuts/seeds (cached and retrieved later), insects, small vertebrates such as lizards and frogs, bird eggs and nestlings, berries, and backyard fruit/feeder food (sunflower seeds and peanuts favored)
