I hope to never meet someone who doesn’t like Bushtits. These little balls of fluff with long tails are always a treat to see.
Despite their tiny size, they are very vocal and come very close to people as they glean small insects from the foliage. It is difficult for such a small creature to maintain its body heat, so Bushtits huddle together for warmth, build enclosed insulated nests, and eat about 80% of their own weight in food every day. In addition to insects, they will eat suet or peanut butter at feeders, and will occasionally take little bits of sunflower seed that have softened in the rain.
unbearably cute

Yes, so cuddly!
Today was the second time the bushtits went to the seed tray after stopping by the feeder. I mentioned it to the birdseed man and he said maybe there were some bugs in the seed. I like your thought of some chips that may have softened due to moisture
