Allopreening

This morning I watched two mourning doves on the walk behind the house. One (female?)  was standing still, close to the second one (male?) who was completing a thorough grooming. Feathers settled, the second one then began to peck at the first one’s neck and head. A quick search lead me to this blog post at poweredbybirds.com, where I learned the term “allopreening” for this behavior.
