We aren't allowed to put food out for the birds as it attracts all sorts lol. 
We did find a chipmunk in dd's room in the basement when ds moved a cushion, though... Spent an hour trying to shoo it out of the door.
Then the following week we kept hearing scratching in the walls, we laid a few traps and caught a chipmunk, celebrated, but the scratching didn't stop. and I eventually made dh cut a big fuck off hole in the plasterboard because it was driving me crazy. Nothing there. So I made him cut a bigger hole further back, obv.
He peeked in and then slammed it shut really quickly, holding the section in place and squealing 'quick, quick, there's two, get my work gloves and a box or bag or something'. I disappeared into the garage to find stuff and then could hear him squealing, ran back to see if he was ok (thinking, shit, rabies) and he said 'one got out!' (and apparently ran up his arm and over his shoulder in the process). So he's still holding the bit of wall in the hole, and I'm running around trying to herd the two squirrels that had escaped (!) out of the door, going 'there's two! There's two! Are you sure there's another one in there?' so he looks and drops the bit of wall, another one runs over his head, and he makes a wild grab inside the wall and comes out with two more, sort of caught by the legs and going doolally) which he runs out of the door with and launches off the deck... We spent fecking hours corralling them and getting them outside, but it was the funniest afternoon we've had in a long time. They were everywhere on the beds, climbing up the ironing board, running under the furniture.... The squirrels that flew c/o dh spent hours in one of the trees outside, chattering and swearing and staring at the house.
Dh thinks they have spent the winter plotting and will be back in the spring.
