Robins!
Robins always shout spring to me. On this cold and snowy January day as I was walking, looking around, listening... I saw my first robins of the year. They were hopping about, from shrub to snow, and back into the air. Chirping, hopping, bringing hopes of spring. (And yes, I have accepted the fact that winter will be with us for weeks yet. It was still good to see my first robins.)
