Just now an adult male Coopers hawk made run a bitties in front yard. Rooster engaged him forcing hawk to divert and land on fence post about 100 feet away. Eduardo (rooster) positioned himself very efffectively between brood and hawk. Hawk tried to wait for opening. Sallie (hen) called bitties up under skirt and kept herself oriented towards hawk. Hawk flew off after easier fair. Bitties have about six more weeks of being vulnerable and baby song birds will become abundant before that. I wish my doms would put up same protective net around their broods. They just make racket or run.
