Woodhouse’s Scrub-Jay or Blue Jay?

General appearance

Blue Jays have a distinctive appearance with a size similar to a crow. Their dull blue-gray back contrasts with their bright blue wings and tail. They have a prominent crest, a black necklace and white patterns on their wing-bars and tail corners. The bird's wings are broad, fingered and rounded, possessing a long, rounded and wedge-shaped tail.

Male vs female

Interestingly, there is little to no difference in the physical appearance between male and female Blue Jays. Both sexes exhibit the same coloration and patterns. Any differences are minimal and often indistinguishable to the untrained eye.

Juvenile

Juvenile Blue Jays are similar in appearance to adults but may be slightly duller in color. They also lack the full crest of adult birds until they mature. Still, their inherent blue hue combined with gray, black and white patterns provides a good marker for identification.

Primary habitat

Blue Jays prefer deciduous or mixed woods with oak or beech trees. They avoid exclusively coniferous forests.

Additional range

They can also be found in suburban gardens, city parks, groves and towns, sometimes even well-wooded suburbs or low, scrubby forest in their southern range.

Natural diet

The blue jay is omnivorous, primarily consuming a diet with a significant portion of vegetable matter. Up to 75% of its diet consists of acorns, beechnuts, other nuts, along with various seeds, grains, berries, and small fruits. In winter, this percentage is higher. Additionally, it eats cultivated fruits. The blue jay's diet also includes many insects like caterpillars, beetles, and grasshoppers, as well as spiders, snails, and occasionally bird eggs, small rodents, frogs, baby birds, carrion, and other items.

Bird feeders

At bird feeders, blue jays are commonly seen eating sunflower seeds, peanuts, and suet. They are known for their bold behavior, often dominating the feeding stations they visit.
