On a blustery winter day such as today the birds really appreciate backyard feeders and ours has been full of birds all day. One of the more common birds is always the House Sparrow, I took this shot yesterday. They were originally introduced from Europe in the mid 19th century and so are an invasive species. They aggressively compete with native species and they are so well established after 150 or so years that it is safe to say they are here for good. They are still a rather attractive bird and I always enjoy photographing them.
