Question: what is the difference between a blue jay and a steller's jay?
Answer: Steller's most common call is a harsher “shaak, shaak, shaak.” ... Both are about 11-12 inches in size with Steller's being slightly larger. With its black hood and dark blue feathers, Steller's is easy to distinguish from the Blue Jay, which has a light grayish chest and white spotting on the wings and tail.
