Reminds me of a joke I liked, the difference between a hummer and a porcupine,
The pricks are on the inside.
The humming birds around here are so hit and miss. My lady friend uses my expensive organic sugar to feed them and then they don't drink the stuff. Then she throws it out and makes more. Sometimes earwigs get into it.
One of the saddest things I was ever told, was about a leaking feeder, and the birds got stuck on a window sill and died.
