The wrens that hang out in my yard have built nests under the "hat" on the propane tank, in the grass catcher attachment for the mower, in the middle of open screw boxes while the screen room was being built, in assorted pots, not just the epi, in a wicker basket hanging on the patio waiting for a plant which had to wait on the wrens and my favorite place was on the ledge of the bathroom window....located in the shower area. It was such fun to take a shower "with the wrens" when they fed the kids. Crazy, curious, endearing and frustrating little birds
