I'm only here for the seeds

Late afternoon snack time in the bird world.  Chickadees flit in and out of the feeders grabbing a sunflower seed and flying back to the trees to crack it open. The weight of a chickadee is 1/4 of an oz. ,i.e.: 64 chickadees to the pound.No wonder they feel so light when you get them to grab a seed from your hand!
