Are You talking about in the Winter time or when they starting having their Young?
Around here Racoons will Go up in their Den Tree's during daylight hours year round then come down in the late evenings,night time and early mornings mostly.In the Winter time they will stay in Dens,Hollow Trees and move much more to look for food and stay warm....I'm thinking they have their Young around Feb,March or April because I've seen Young ones that were weened and traveling with Momma Racoon starting in June & July!
