Wintering hummingbirds in Washington state (1 Viewer)

I'm wondering if anyone can help me with some info?
My family and I were clearing up fallen branches from our snow/ice storm and I ran across 2 hummingbirds. They looked to be in good health and fairly active. What I'm wondering is, should I go ahead and put a feeder out for them? How common is it for hummers to remain in semi-cold winter states?
How can I help to make sure their winter is comfortable?

Thanks for the help,
Tammy

These are most likely Anna's Hummingbirds. They do stay in the North West in winter and by all means put out a feeder. The usual mixture in winter is 1 part sugar to 3 parts water. Later in spring and summer change to a 1to 4 ratio. Enjoy them, they are a great treat to watch.

Thank you for the info. We got the feeders out and will be making up the water tonight. Can't wait to see them up close.|=)|
