A common year round resident in western interior valleys and east from Lake County and Klamath County northward to Bend. Variety of open deciduous habitats, including agricultural and residential areas, brushy hillsides, oak woodlands and juniper forests.


Form long-term pair bonds that live throughout the year on a fixed territory. The young of a pair remain close by for up to a couple years, helping parents raise subsequent brothers and sisters. They can become tame at picnic areas, parks, and feeders. The Scrub Jay caches food by burying it for later consumption. When it’s time to eat the acorns, which form a staple of the winter diet, these intelligent birds often use a rock or concrete slab as an anvil to assist in cracking open the hard shell to get at the edible parts. Because they do not retrieve all of their hidden stashes, many acorns germinate, thus renewing the oak stand and keeping the resident jays supplied for life.


Pinyon Jay is found in Central Oregon and is lighter blue overall.

Stellar’s Jay is same size, but has an all black head and pointed black crest. Gray Jay is gray and white, lacking any of the Scrub Jay’s blue color.
