Eastern bluebirds – comings and goings

On the southwest end of Como Park is an active bluebird nesting box.  The parents are coming and going constantly with food and maintenance.  The female frequently exits the nest with a small white “bundle.”  According to a site called bluebirdnut.com, “The parents are very meticulous about cleaning up the nestbox. When the eggs hatch, the female usually eats the eggshells to help with her egg production or disposes of them far away from the nestbox. While the babies are growing, the parents will carry away the waste products from the nestlings. The waste is in the form of neat little bundles called “fecal sacs”.
