Wilson's Warbler, a flycatching Warbler of the lower growth, favors
bushes near water, but is also found in dryer places. Thayer in
"Warblers of North America" says that its "song has much of the ringing
clarity of the Canada's and Hooded's songs." It nests on the ground,
laying 4 eggs, usually with a wreath of spots at the larger end, early
in June.
