Seiurus noveboracensis. Maine (Lake Umbagog). 1879. June 3. Two nests; one with four, the other with five eggs. Both sets incubated about six days. The first nest was in the side of an earth-laden root on the north side of B Point on the Lake shore. This nest was not concealed like the one found yesterday, being simply set in the side of the bank. I could see the eggs from a distance of ten feet. The female was not sitting but soon after I discovered the nest Shehadher mate appeared, both chirping sharply, showing much anxiety, and running over the mossy ground within six feet of me. The second nest was concealed nearly as perfectly as the one found yes- terday; it was completely overshadowed by the bank which projected down above its entrance, and the eggs could not be seen until I had torn away the overhanging earth. June 3). be seen until I had torn away the overhanging earth. The female was sitting, she started off when I was with- in a few foot raising her extended wings above her back and spreading her tail tothe fullest extent. While I was packing the eggs she was constantly within fifteen feet of me and sometimes almost within reach of my arm. At first she was silent but shortly afterwards she began a sharp chirping. The male was singing meanwhile in the distance but he did not appear. " 5. D-4 Nest containing four eggs incubated about ten days: in root bank, overshadowed by the earth above but not other- wise concealed. The eggs could be seen from in front. The female sat so closely that I walked past the face of the bank without flushing her. Upon returning and stooping down at its base she fluttered out directly un- der my nose. The nest was not more than six inches above the ground. I notice than when the earth bank is entirely above high-water mark the nest is placed near the ground. When otherwise, it is higher in the bank, often near its top. " 13. Set of five eggs incubated several days. Nest in cavity of root-bank about six inches above base. The female sat closely: I saw her on the nest and nearly touched yhor with my finger tips when she slid off and glided about among the ferns like a mouse, expanding and spreading her wings above her back. She did not fly at all, but continued running about in this manner while we remained near the spot; she also kept perfectly si- lent. The male did not appear. This nest was simply overshadowed with the bank; it was in the depths of a gloomy swamp on B Point. 41
