Okay lemme first defend myself by saying that I didn't have any string, just ribbon. No wait, that wasn't what I wanted to defend. Oh yeah. The whole do or don't feed the wild birds thing. Well, for a long time I bought into the whole anti side. "If you feed them they will forget how to forage for themselves" and, "then if you STOP feeding them they will DIE!!!!!!" But I started thinking that if birds have, say, a favorite berry bush that dies... well, they find another one. And I just can't believe that mother nature would be that dumb to make critters that can survive thousands of years (generation wise) that would die just from one food source drying up. And if that REALLY is the case... well, it's going to sound awful but.... more food for the next critter in the chain o' life. I really, really doubt that my feeding the birds can extinct a species. There. I said it. So I did what I have always wanted to do, and made these feeders. I tucked peanut butter in all the nooks and crannies of these pinecones and then coated them with seeds. Then I hung 'em up and within a day there were these cute little black gray and white birds all chirping and fluttering right out side my window. In just a few days they had cleaned them 'cones better n' a dishwasher. (I wish I had a dishwasher) So I have been re-coating the cones maybe once a week- they stand empty for a few days SO THERE the birds still have to forage! LOL But man those lil birds make me smile with their acrobatics. And I swear I can tell they're getting fatter. They make me happy and I think it's mutual.
