The Stellars Jay ( Cyanocitta stelleri ) is a common character found in the forests of the western half of the United States. The bird is an opportunistic omnivore and closely related to the Blue Jay. The Stellars Jay has a black crested head and a vibrant blue body which is commonly about between eleven and twelve inches long. This bird has a lot of variations depending on location.

This bird commonly feeds upon seeds, nuts and acorns. Speaking from first hand information, they also love unsalted peanuts. The will also eat insects and other small invertebrates, including mammals. They are also known to raid other birds nests and can be very aggressive with other birds.

Stellars Jay breed in monogamous pairs and a clutch of eggs is typically 3 – 5 in number. Both parents are active is feeding the young.
