I put a dish on top of the new Bluebird Nut Mealworm Feeder with some mealies along w/some inside when I saw the blues yesterday. Blues didn't come back but mocker found the ones on top. I have mounted mine on a post due to our high winds and put a branch thru the mesh (Cher's suggestion, THANKS CHER) and I think it will work out great. I was worried that the blues wouldn't be able to get inside easily due to the roof getting to hot here (south of Dallas TX). The mocker was not able to enter the feeder! Sorry no pic yet. I have a slow connection at home and it is hard to put pics on photobucket.
