One showed darker discoloration than the other.
Sandhill Cranes are long-lived - up to 20 year - are monogamous, and stay together as a pair.
One of them ventured too close to a Red-winged Blackbird's nest and had to fend off an attack.
Stretching of wings but not taking off - just yet. I thought I had taken enough pics and had sat back down in the car, thus missing the dramatic end to the show as the pair took off, their clamor filling the the air with hoarse honking and loud swooshing of wings. They flew low and settled again at the far end of the field, well out of my lens' range.
Happy Birding! Please leave a comment.
