A woman came in to the Sandy Hook Bird Observatory gift shop yesterday and purchased replacement yellow flowers for a hummingbird feeder like the one above. I commented how they sometimes get moldy no matter how regularly you clean them. She said, "No, that's not it. I have a Pileated Woodpecker that likes to cling to the feeder and peck the heck out of them!" That's one I hadn't heard before! I tried to find photos or videos of such a thing online, but no luck.
