Siurus naevius. Maine (Lake Umbagog). 1872. June 3- 14. Not common around the lake but literally swarming in the swampy thickets bordering Cambridge River above the dam. There was a striking uniformity in the songs of different individuals of this species. The male usually sings low down in the darkest recesses of his retreat. 1874. Aug. 3. Saw one on Cambridge River. " 18. One singing superbly on an Island in Leonard's Pond, his ringing warble sounding all the finer from the per- fect silence around. 1879. ejay③ May 24. I discovered this evening that the Water Thrush sing in the air like the Oven Bird. I saw one rise to the height of several hundred feet above the tallest trees and then descend, uttering its usual song, followed by a continued, tremulous, varied, and exquisitely tender warble. This termination is very similar to that of the Oven-bird. The bird descends on an incline plane. " 24. A single male singing yesterday. Numbers heard today. " 25. At mid-day during a passing shower a male soared above the woods singing in the manner all ready descri- bed. June 2. A-4 Nest with four eggs incubated about eight days, placed in the vertical side of a wall of earth adhering to the roots of a fallen tree overarched by the earth in which the cavity had been excavated for its reception. This was additionally protected, both from the weather and observation, by a tangle of flexible earth-laden roots that hung down like a curtain before its entrance. I brushed against this curtain while passing, when the sitting bird fluttered out from behind it and tumbled out on the ground at my feet, simulating lameness. She did not utter any sound, however, and the two males singing in the vicinity did not come near the spot. Walm. 7' Curt 40
