Oh, I wish I had a camera with me today! The field next to the playground -- full of geese. Hundreds of geese. They hang out there all the time. I see them flying over our house and know they're on their way to that field, -- a few fields really -- since it's only about four blocks away. Anyway, there the geese are, calmly standing around Kids playing on the playground alongside the field. Suddenly, the entire flock just rises up into the air, making these odd sounds, sort of like distress calls but not exactly, not really that. Never heard that sound before. I couldn't see anything that set them off -- any other bird, etc. The geese flew right above our heads on the playground --- and the kids! The children just ran and laughed and screamed and ran, while the geese circled low above us. Then the geese did this spiral kind of thing -- like a crop circle in the air. They just kept circling above us, then flew right back to where they were, and settled down like nothing had happened. Those geese have been there all winter, and are used to the children playing out there -- a fence divides the playground from the fields -- maybe the geese were just saying hello.
