Spring is here! ...somewhere...

It may be spring in the astronomical sense, but many are still waiting for some of the more anticipated indications that spring has arrived.  To get past the dreary, gray day here at Woods Reader, we are thinking about our favorite signs that spring truly has arrived.  These include sounds of birdsong from returning bird species, the emergence of Lily of the Valley with its delicate scent, the soft tufts of the pussy willow and the pitter-pat of rain dripping from branches onto the forest floor.  What are your favorite signs of spring in the woods?
