1. Tool use in birds is rare. Although no tool use has been reported for wild Blue Jays, captive jays used strips of newspaper to rake in food pellets from outside of their cages.

2. This species shows a great deal of variation in appearance throughout its range, with some populations featuring black crests and backs, and others blue. One black-crested form in southern Mexico is surrounded by eight other blue-crested forms.

3. In areas where acorns are abundant, this species has deep, stout, slightly hooked bills. Those in areas with lots of pinyon pine have long, shallow, pointed bills. The shape of the bill helps the jays open their preferred foods: a stout bill is good for hammering open acorns and the hook helps rip off the shell; a thinner, more pointed bill can get in between pine cone scales to get at the pine seeds.

4. Although omnivorous, this species is committed to the harvest, transport, caching, and later retrieval of pine seeds. It is aided by a relatively long, strong bill; an expandable esophagus; and long, strong wings. Individuals have excellent spatial memories that allow them to find most of their hidden seeds months after caching, even through snow.
