Yes. It was silent. I didn't notice until afterwards when the song birds started up again and the mice started hopping around in the dead leaves. Lesson for me - I just didn't notice it was so quiet.I have netting around the magnolia tree to close off areas that become vulnerable to Cooper's hawks after the leaves have dropped. Even with all of my losses to the hawks I can't keep them locked in all the time. It does not protect them for me to be out with them. The hawks don't care.
Their best protection is their own system of defense. My ladies always have someone filling the roosters duty as a Sentinel. It is obvious who is responsible for everyone else's safety. Mine have learned the hard way that this is necessary and they are quite diligent about it. The role is shared but some never take it. Hattie is never Sentinel. I believe this is because she was on duty the day the hawk killed Sylvie and they no longer trust her. Phyllis is also never Sentinel as she cannot see upwards. The rest all take turns. Glynda and Lady Featherington have been taught the danger and the job by the others. These lessons are learned and passed down. I expect that @RoyalChick tribe will be making adjustments and will be much safer moving forward.
RC, did it get very quiet before the attack? Did the song birds stop talking? That has happened before all of my Cooper's Hawk attacks. The song birds know they are there and go into hiding. That is a warning hopefully your girls now know.
That does not happen when a red-tailed hawk attacks. They come from much higher up and everyone is surprised.
