Yeah, I put thistle seeds out for the finches. they just love them. I had to add a second feeder for them they go through them so fast, and yes, they are quite expensive. I need to get better finch feeders that have the bowl thingy underneath to catch the fallout. I end up with half the seed on the porch. It's messy AND wasteful. After Christmas, I am going to have do some more serious browsing at that wild bird place in Little Rock. Can't afford it right now, although, one of those specialty feeders might make a nice gift for my dad and stepmom. They are really into the birds too. It must run in the family.
