I bought 4 of these nesting baskets from bestnest.com a few months back - they were around $6 each. I hung all 4 underneath my back deck - it's about 5 ft off the ground. Can't really hang them from a tree - they are just woven twigs and vines and wouldn't offer much protection from rain but under the deck edge they do fine.
I suspected something was in a few of them a couple weeks ago when I saw fresh moss in 3 of them.
While weedeating today I saw a brownheaded nuthatch fly out of there. Found one of them full of eggs!.
