I never heard racoons making noise. I used to feed them on our back deck in the mountains. The mama started bringing her babies there, every winter. She would leave them on the deck to go forage. Cutest things ever. I was so honored she trusted me to babysit. She and her babies would look through our sliding glass door and bounce their hands up and down. I never heard any noise but I never had the door open when they were around either. I still don’t know what that means but that probably means feed me.
Around 8 of them show up at the bird 3rdfeeders around 10 o’clock. They must be territorial.
