Are robins really a sign of spring?

This male robin was hanging around Columbia River Park Thursday morning. 

Robins are considered a sign of spring in our area. Their arrival is often associated with the changing of seasons and the onset of warmer weather.

Many robins migrate during the winter, typically to warmer southern regions in search of food and more favorable weather conditions, but their migration patterns can be complex. Some may also stay in the area year-round if they are able to find sufficient food sources.
