Dendroica coronata. Lake Umbagog, Maine. Nest. 1897. Watrous had previously found two Warbler's nests in a June 14. grove of large hemlocks close to the shore near the "Gut". One proved to be an old nest but the other was a Yellow-rump's with four eggs rather far advanced in incubation. This nest was in a hemlock on a stout horizontal branch about 5 ft. from its extremity, 10 ft. from the main trunk, 35 ft. above the ground, and the same distance from the top of the tree. The female Yellow-rump was sitting and for some time she absolutely refused to leave her eggs. Watrous first shook the branch and then with a long stick poked and shook smartly the twigs within an inch or two of her head. At length she hopped out of the nest and stood for a moment or more on its rim looking about her. Then she fluttered down towards the ground with quivering wings and wide spread tail moving slowly and alighting several times on a branch or cluster of twigs would where she ^lie prostrate for a moment beating her wings feebly and simulating the movements of a wounded or otherwise disa- bled bird. In short she behaved precisely as one of the ground-nesting birds (Seiurus for example) will do under simi- lar circumstances. Watrous secured this nest and set in the same manner as that by which he took the Bay-breast's earlier in the day. The nest was lined with feathers as usual but from beneath it looked so nearly like a Bay-breast's that we
