Sylvania pusilla. Lake Umbagog, Maine. 1896. June 12. After launching our boat (at Lakeside) under the old elm we paddled down into the steamer cove where just below the school house I was surprised to hear a Wilson's Black-cap singing. Landing I spent an hour or more searching for its nest. The male bird came within two yards or less and followed me about resuming its song whenever I passed beyond certain limits within which I have little doubt that its mate and nest were somewhere concealed. The place was somewhat peculiar - low and springy ground with thickets of alders alternating with small openings and with many moss-covered mounds and boulders all of which I inspected with especial care. The male bird did not once chirp but yet its manner led me to infer at once that it was settled and nesting. Probably nesting. color 4 1896 Wilsonia pusilla Lake Umbagog Me Cep. 22 Saw an adult in full autumnal plumage in alders in company with what I took to be a group of the same sex, and an adult & Resident.
