Every Spring a female, maybe male, or both together, make a nest !!!! (on my Mom and Dad’s patio, high patio) then lays her eggs !!!!! THEN after all that work, the momma bird sits on them !!!!!!!! And then feeds them !!!!!!! once they hatch out of their pretty blue eggs!!!!! And then teaches them to leave the nest and fly. And the momma Robin and papa , male robin scares off the crows who wahat to swoop in and eat the babies while the momma Robin and papa Robyn are finding food to fed their baby birds. WOW. God made them to do all that. WOW.
