These days, we just never know who we'll see around the backyard.
This is a Ruby-crowned Kinglet, a small olive greenish songbird with a white wingbar with a blackish bar adjacent on the wing.
The faint white eye ring makes it seem to have very large eyes.
When the adult males get excited they flash a brilliant red crown.
In the summer, these little birds are commonly found in spruce-fir forests across the Northwestern United States and throughout Canada, and nest high in trees.
In the winter and during migration they are common in thickets throughout North America.
If there is food in your backyard, these quick moving birds may come.
They eat spiders, insects, ants, wasps, seeds and fruit.
