Blue Jay vs Eastern Bluebird

The check that settles it

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

Blue Jay

Cyanocitta cristata

Size
2530 cm
Bill
conical
Where
feeder, yard, woodland
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.

Eastern Bluebird

Sialia sialis

Size
1621 cm
Bill
thin pointed
Where
open field, yard
Voice
A soft musical 'chur-lee, chur-lee'.

Confirming a blue jay

  • 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.

Confirming a eastern bluebird

  • Blue above with an orange throat and chest and a clean white belly.
  • Perches upright on wires and posts over open grass, then drops to the ground.
  • Round-headed with a short thin bill.
  • Females are much duller — grey-blue with a paler orange wash.
