bluebird

BLOO-burd
A day of perfect weather — cloudless sky, calm wind, clean visibility. The kind of day that makes you bail on whatever you were planning to do indoors.
Etymology
Skier and climber slang, American West. The blue is the sky itself, uninterrupted. Sometimes shortened to bluebie (“blue-bee”). Stands in contrast to graybird.
