Vireo olitaris, brood of young cock MASS. (Middlesex Co.) 1875. June 15 absolutely nothing worthy of mention. Found two nests of Vireo olitarius (4 & eggs well advanced); a nest of Sethe. buteulata well along; and a nest of D. risors in a yellowspine about 20 ft. up, with the lining torn out and empty. The I was singing near the spot and probably the Lord nest was somewhere near. Found a pair of Vireo olitarius in a piece of heavy timber and a few strips of bark etc. attached to a pendant oak twig about the height of one's head indicated perhaps the site of the future nest. Stumbled upon a brood of four cock in @ tall maple & oak growth near a brook. Two of the young saw first that the old 2 and crept the two remaining youngs. They now lying close together but scattered in all directions at the first bow. Marking one of the young birds carefully I flushed him again when he went off in good style for some 200 yds. At this the mother bird which had disappeared at the first alarm over a scroll, came back and flying slowly by with dangling legs bit within ten yards and with wings wide spread fluttered off over the leaves trying poor thing to induce us to follow her. The young were about two-thirds grown or the size of an English snipe. Neither they nor the parent produced any audible whistling etc in flying. I think this is the 2nd clutch of the same parents that I noticed of their eggs in Apr.
