About a mile south, on the crest of the hill, is an overgrown field which was once part of the old Chase Farm. Here, on May 12th, 1924, I ran into an army of migrating Warblers and among them were full companies of the BAYBREAST.
In the white birches were dozens of their dark leisurely-moving forms. They were migrating at about the speed of my walk and I followed them home and there in the orchard trees was another brigade! I think, they must have rendesvoused and agreed to travel in regiments for I saw more on that day than in all previous years.
