Black capped chickadee - cavity excavation

I stumbled on a great find this past weekend - black capped chickadees actually doing some of their own home building!  Two birds, assumed male and female, spent time in and out of the cavity you can see in the pics.  They were taking out material from inside the cavity, most likely enlarging the cavity itself.
