Antrostomus vociferus. Lake Umbagog, Maine. 1888 Antrostomus vociferus ✓ Late singing Sept. 11 At daylight this morning I heard a Whippoorwill at the Sluice when we were camping. He uttered his cry about 5 times in the usual quick succession. He did not ing a second time nor did we hear him the previous evening which was Still, clear & warm. This evening the same bird sang at frequent intervals for fifteen or twenty minutes. The greatest number of repetitions of the “whippoorwill” was nine. At Machias last June I counted 158 without an intervening pause.
