I was in the gardening, flower section of Walmart today, just sitting there waiting for someone else to get done shopping. It's quite open air there, big sections anyway. And birds have come in and were swooping around.
I saw one interesting thing, a bird -- I think it was a sparrow -- went down and found a piece of a Boston fern. He flew it up in the rafters and it fell and the bird accompanied it all the way down at about the same speed. He picked it up against and went to the rafters. Then it fell again, but this time landed on top of a light fixture. He went there and picked it up and went to the rafters again, and this time managed to secure it.
The checkout lady either didn't notice or didn't mind that the bird clearly stole a piece of a fern.
