I was watching the feeders on my deck this morning, hoping a Pine Siskin would show up, when I saw a Yellow-rumped go to the seed feeder and eat a sunflower chip (sunflower with no shell). The bird then went to the peanut feeder and ate a small bit of a nut. I thought it was just a fluke, and figured the bird was looking for suet or meal worms, but the bird was there this afternoon, eating more sunflower chips, while it ignored the mealworm feeder I had put out. It landed on the peanut feeder too, but I couldn't tell if it ate any. It flew to my front yard and ate some suet, but once again went to the seed feeder and seemed to prefer the sunflower chips. I have often seen Pine Warblers eat sunflower chips, but this is the first time I've seen a Yellow-rumped do it. I took a couple photos.
