Last Saturday, August the 8th, was "house cleaning day" at the Western Bluebird nesting box located at the Pavilion in the Dallas Retirement Village. The mother bluebird is shown removing a fecal sac, which is a white coated sack that surrounds the baby bird's waste. Bluebirds keep one of the cleanest nests of songbirds, and this is a daily task necessary to take care of the four baby birds in the nest. Both the male and the female share in the work of bringing food in and carrying out the fecal sacs.
Great photo. We once watched house wrens depositing their baby's fecal sacks on the twigs of a skinny dead tree! The tree had a dozen fecal sacs on it!
