D.C. has just two known nesting pairs of eagles, and no one is exactly sure where one of them has gone.

The two were seen on camera mating Saturday afternoon.

Liberty hasn’t been seen at her nest above the D.C. police academy for three days now. The two eggs she had been struggling to incubate are no longer viable.

Every day, hundreds of people watch with bated breath as the drama unfolds at Liberty and Justice’s nest.
