Don't forget about the birds

I worked in the garden yesterday.  Did a lot of cleaning out, ripping up, and trimming.  I know that I only have about a month of warmish weather left, and that's a hopeful estimate.  We've had snow in September before.  I cut down all the Sunflower plants.  If the birds hadn't gotten to them yet, I simply clipped off the flower head, and put it in a bucket.  There are five bird feeders in the back yard, reason being, I figure if I give them plenty of places to eat from, they will leave my plants and produce alone.  Anyway, everyday  I add a couple of flower heads to each  feeder.  They seem to enjoy sunflower seeds no matter how they acquire them.
