Thanks to everyone for the thumbs and acorns! Hope some of you enjoy your own bird tree. As PlantinThings noted, it works to leave the tree up for several months into the winter - ours usually doesn't dry out at all due to all the rain we get. I do take the lights off when it's time to pack up the holiday, but continue to toss popcorn and birdseed into the branches on a regular basis. CritterGarden, let us know how the solar lights work out. Good idea if there is not a plug-in handy.
