As temperatures drop and snow piles up, it can be a challenging time for birds in the area. County Naturalist Marla Murtz says that birds have had a pretty easy time so far this year but it will become increasingly difficult for them to survive as winter drags on. She says oil sunflower seeds are the best food for birds this time of year, as the seeds provide lots of protein and fat to get the birds through the cold nights. She advices people not to put out salted foods for birds, as salt acts as a poison on birds. Murtz adds that giving the birds access to drinking water is even more important than keeping them fed.
