Turdus ustulatus swainsonii. Lake Umbagog, Maine. Nest. 1897. Returning to the boats (we were on the northern end of June 14. Great Island) we pulled out of the cove and long the shore to a spot where, on June 11th, I had found an empty nest of Swainson's Thrush only a few rods back from the water. It was built in a slender spruce sapling close against the main stem, about 8 feet above the ground, and some two feet from the extreme top of the tree - altogether a typical situation. This nest was the most beautiful one of its kind that I have ever seen, very large and thick-walled with much Usnea on the outside. It contained four handsomely-marked eggs to-day. Neither bird was near the nest when we first reached it but one of them afterwards came flitting about us, making a low, whining call.
