Slightly larger than a robin, the Blue Jay would be considered amazingly beautiful if it were not so common.  It was initially a forest bird that has adapted to living in towns and cities with groves of trees.  Despite its striking plumage it is surprisingly inconspicuous as it forges in the foliage of trees and shrubs.  However, its large repertoire of calls and songs will often announce its presence in the upland area of Salter Grove.  

Its diet includes a great variety of plant (acorns, berries, grains, seeds) and animal matter (beetles, caterpillars, grasshoppers, frogs, rodents).  Bird feeders at houses around the park no doubt contribute greatly to its winter diet.
