Blue Jay

Cyanocitta cristata

Also called jay.

Loud, bold and unmistakable in the east. The blue is structural rather than pigment — a blue jay feather ground to powder is brown, which is why the colour shifts so much with the light.

Size

Bill

What it looks like

Bright blue above with black barring on the wings and tail, white wing patches, a white face and a black necklace across the throat. A prominent blue crest.

The checks that confirm it

  • Blue with a black necklace and a crest.
  • White patches in the wing and white corners to the tail, obvious in flight.
  • Black barring across the blue of the wings and tail.

Voice

A harsh descending 'jaay'. Also an astonishing imitation of a red-shouldered hawk, which empties a feeder in seconds and is often done for exactly that reason.

Attracting it

Peanuts in the shell and sunflower seed on a platform feeder. They cache far more than they eat.

Confused with

Steller's jay

Western, and much darker — a sooty black head and chest with a very tall crest.

Much smaller, no crest, orange breast, and it perches in the open rather than moving through cover.
