My daughter Lia and I are amazed at the strength & endurance of this little female Rufous hummingbird as she seems to survive all this cold weather and sits patiently waiting on my daughter to replace a quickly freezing feeder about every 2 hours. The little hummer spends a lot of time in the two evergreen trees about 50 feet behind the feeders. We hope she is able to continue to amaze us with her endurance until she decides to return to her summer home. Glen Eller Kingsport, TN
