Quiscalus q. aeneus. Lake Umbagog, Maine. Killing a Water Thrush? 1897. The Bronzed Grackles have a small roost in a dense thick- June 8. et of second growth birches and poplars on the island in Leon- ard's Pond. To this ten or a dozen birds of both sexes fly by twos and threes soon after sunset every evening. The ground under the trees is covered with their droppings. Wat- rous found a Water Thrush's nest in a small root bank directly beneath this roost. It contained five eggs about a week ago but when I visited it with him on the 6th the eggs were all broken and the shells intermingled with the lining of the nest while the pool of water beneath was strewn with the Wa- ter Thrush's feathers. Could a Grackle have committed this foul deed?
