Western Bluebird

Sialia mexicana

Also known as Mexican Bluebird

Bright cobalt-blue feathers mantle the male Western Bluebird, contrasting sharply with a rust-red chest and upper back patch. These social thrushes spend winters in roving family flocks, gleaning mistletoe berries and dropping from low perches to snatch insects off the ground. Pairs readily adopt artificial nest boxes placed along woodland edges where natural tree cavities have become scarce.

Responsible observation
  • Nest Boxes: Mount predator-guarded birdhouses in open woodland openings to aid breeding pairs.
  • Winter Feeding: Plant berry-producing native shrubs like mistletoe and elderberry for seasonal food.
  • Field Observation: Watch fence lines and lower branches where birds pause before pouncing on ground prey.
