This bamboo is home to a couple of my humming bird friends. Somehow they manage to hang around all winter long with the aide of a feeder. Although it doesn't freeze often here in Portland OR it does freeze once and awhile so the feeder is brought in over night and put out, promptly, in the morning.
Apparently the bamboo is dense enough to keep the birds fairly dry and makes a good wind break as well. It is amazing how close they come to me, sometimes only a foot away. I'm sure they are making sure their food is safe.
