观察细节
Several singing males in the area - at least 4 heard well. There were fewer singing males this morning than in weeks past. Still hearing vocalizations that might indicate breeding is still occurring here. The "rare" status for this species at this location should be re-evaluated. There is a very healthy breeding population here.
