backyard birds brave the cold

Its much too cold this week! I've been worrying about our backyard birds. I don't know why that silly robin didn't fly south this year! Really a bad choice. I am glad that the birds (and squirrels) are enjoying my window feeder. The birds also like to drink from our pond. A couple of days ago it froze except for a little hole at the center. Yesterday I went out, braved the cold, and put the pond heater in again. Unfortunately, the circuit tripped for some reason and today I noticed the pond is completely frozen over. Just now, I went out and reset the circuit. I hope the water thaws so the birds can drink it tomorrow.
