Chessyr,
This is the House Wren, we also have a Winter, Carolina, Bewick’s, Cactus, Rock, and Marsh Wrens in the states. They are hard to tell apart. Slight differences in size, call, and shades of brown:) They are a very neat bird and small.

The lens I used is not IS, it is a Nikon 300f4, an old one. I did have it on a tripod though. Kind of Mechanical IS:)
