It does record sound. Haha, not sure about “delicate’ but I’ll record some. No sound in the above footage as it was slowed down. I grab another shot during feeding time in the morning. We have dozens of them come in each day.
They have a funny hierarchy. There are two birds that live in our tree and have claim they always eat first and never allow the others down to share. They just all sit up in the branches and watch. Once our pair have finished, they send out the “ok” and then the masses come down to feed. It’s amazing to watch
