If you are asleep . . .

 . . . you will miss a flicker chipping and hauling wood from an already weakened tree to make its nest. Like the entrances of woodpecker relatives, its hole will be perfectly round and filled, one per day, with 5-8 eggs (twice between February and July). Once their eggs are laid, the parents never leave them unattended, assuring starlings and squirrels can't take over the nest. Next season another bird family will move into flicker's nest, while flicker burrows a new hole.
