Habits of the young warblers 175 MASS. (Middlesex Co.) 1875. July 30 - 1875 July 30. I took a very fair bag of 9 young birds, the best D. virbi 2 D. jina 1 M. vascá 1 S. jusilla 1 D. discor 2 S. Betulorum 1 & C. atratus 1. The habit of many different species assembling together in one large flock I find obtains here at this season nearly as much as in Me. I found to Day Sparrows, warblers, titmice, wood- pigeons etc., keeping company indiscriminately often as many as one hundred or more individuals being assembled in an area of a few hundred yards, very few birds were singing in the woods. I heard one tanagers and an indigo birds but the only species that performed at all frequently was S. jusilla. I found a robin's nest with 2 eggs, the parent bird sitting thereon. In a swamp heard a note entirely new to me, a long drawn plaintive whistle uttered with a rising inflection, Started a very large woodcock under apple trees but he was so shy that I got only one long shot and missed. Very few if any birds have left us yet, except the swallows; they are getting rarer daily and I hear and see them frequently flying over at a great height. The Orchard-masters are however still about their breeding places and a few of each of the other species are still to be found in the meadows. Bee-hives are commencing to sing regularly and I still hear a few -- [illegible] -- toads in the swamps
