If Altera proved one thing last year, it's that she's definitely fit to be a mother. But she's also proven to be less predictable than the late Mrs. Tiger, having left her first egg of Season 6 for over 12 hours. Temps have remained above freezing, leaving the first eggs of a brood unattended is not unusual behavior for owl nesting, but it sure does make us humans anxious.

Will she return tonight to incubate E6.1, and presumably prepare for laying E6.2 some time Sunday? Find out tonight in a special Facebook Live simul-stream of Alessondra's OKC Great Horned Owl Cam starting at 5pm Nest-Time (CST).
