I walked around the pond at lunchtime. Before I got to the real start of the trail I bumped into two people looking up into the trees. They were trying to find what was making a strange call. It was probably just grackles, but the people were from Sweden, not familiar with North American birds. I walked with them a little way, talking about Stockholm, and they turned around near the big log bench next to the water.
There were five ring-necked ducks, one each male hoodie and common merg, a pair of swans, and several Canada geese in the pond. I didn’t see much in land birds other than the grackles at the start.
