Parula americana. 1873. Maine (Lake Umbagog). Aug. 23. The males still sing occasionally. Sept.22. Saw several on Cambridge River. 1879. May 31. Female working on nest in usnea moss, hanging from a branch over the lake. Height forty feet. copy 2 June 13. 3-4 Set of four eggs incubated about four days. Nest in usnea moss hanging from horizontal dead branch, on small spruce, near the Lake shore. Height six feet. This nest was found June 3, when it was empty but appar- ently completed; to-day the female was looking out at our approach; she flew from it when I was about twenty feet away and at once began to chirp when the male ap- peared. After I had taken the eggs, nest, and branch, they hunted for their lost home a long time, carefully examining every little bunch of moss on the tree. Two of their eggs had the contents thickened or congealed so that they were blown with great difficulty; the shells of all were very thick and strong, resisting the point of the drill nearly as much as do Woodpeckers eggs. 1880.

There was no moss elsewhere on the tree which was alive and covered with leaves. This nest was found May 25 when the female was carrying materials into it. S. end of Big Island. 1881. May 12. Numbers.
