My Samantha when she was younger would jump up in the air and catch sparrows. Once the timing was just right on my part and I saw it happen and yelled at her and she dropped it. The little bird was alive and did fly away. It's rather amazing that what they were bred for remains after all these generations of yorkies. I also remember one hot summer day when she sat by my fish pond waiting for a vole to pop it's head up and when it did she grabbed for it but I scolded her and it went down it's hole. She's a senior now, but she's still pretty quick.
