Wood Peckers

While walking today I noticed a pair of wood peckers in this white oak tree. I snapped a few pictures. Days later I noticed the dead tree near by & at first I thought it might should come down. Then I saw all of the holes pecked in this tree. WB saw me looking at it & asked what I was thinking...I told him, I think those wood peckers probably have a nest in the tree, maybe we should not cut in down right now.
