I fill up this adorable feeder with Wagner's 62046 Backyard Wildlife Food, 8-Pound Bag and the squirrels will knock it over when it needs a refill. It is very lightweight, but not plastic. We have attracted all sorts of birds to this feeder. (And squirrels of course) Mourning Doves, Cardinals, Blue Jays, Woodpeckers etc. but I think that has more to do with the food. Definately recommend this purchase!
