Podrobnosti k pozorování
All heard vocalizing more or less simultaneously. While standing at the fork of the path from the front pond to the back pond, I could hear one bird singing from a nearby tree, one calling (pip) behind me at the front pond, one singing from the hawthornes, and one singing from farther up on the hill. Shortly thereafter one starting singing from the vernal ponds (this individual recorded earlier in the day), and finally a sixth started singing father back closer to the back pond. I have suspected the last several days that I have been undercounting but until today I could not be certain how much these birds were moving around the preserve.
