Observation details

Singing at 44°20′16″ N 69°27′15″ W along Sheepscot River and north end of white trail. This bird sang persistently without prompting or playback. There was a relatively long gap between songs, with time between two songs measured in three separate recording bouts: 49 s, 49 s, 36 s. Then in response to playback, the bird aggressively approached and sang songs with much more sputtered endings. This is presumably a bird in the same area as reported by Logan Parker on 26 May. I studied the bird and noted that it was a typical waterthrush, being a medium large warbler with brown upper parts and whitish but dark streaked underparts. There was a bright white supercilium that was broader and whiter behind the eye. The throat was pure white, and the under parts streaked with broadly spaced streaks. The bird dipped and circled its tail including posterior portion of body. Legs pink, eye dark, bill fairly long and heavy for a warbler with some pinkish brown at base of mandible.
