They are now making them using a recycled plastic that is called poly lumber or similar material that if you look closely has small pieces of this plastic that easily comes off and continues to come off and ends up on the bird food which birds can easily end up eating it..... I don't get it why they would choose this material to make it from. I bought one in the past and spent over 1 hour with tweezers trying to get rid of all of it but it never stops coming off. The ground feeders I use are made of cedar wood but they increased the price. Bird's choice 16x20, 3 of them.
