Hushed Willows Itsy Bitsy Birdy

He grinned as she spoke, his eyes lighting up. Smart bird. He hadn't come across very many of these. Wagging his tail slowly, he raised his brow. Worms? Sounded reasonable, but where would he find some? Needing to satisfy his curiousity about this other dog, he got up and bounded over to the rocks. Could they be hiding underneath them? 
Shoving the loose rock aside with his snout, he began digging. The ground was incredibly hard, but his determination was clearly seen in his stance as he continued. Snow and rock flew everywhere as the hole got deeper. Sniffing, he then huffed, trying to get the cold dirt out of his nose. Nothing there. Moving a few feet over, he began to dig again, his brows almost furrowed in concentration. 
About 5 minutes later, his whole back end began to shake as he looked up at the tiny bird. Excitement was heard in his voice as his dirt covered nose huffed again. Here! There might be three. I'm not sure. Moving slightly away from the good sized hole, he sat down and watched, not wanting to startle her.
