384 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



set of a clear, calm evening, or during almost any hour of the day when fine, 

 misty rain is falling. At such times their rich, contralto voices, swelling and 

 sinking in measured cadences, ring and echo through the arches under the trees. 

 When, as not infrequently happens, three or four males are singing within ear- 

 shot of one another, each striving his utmost to outdo his rivals, they furnish 

 a woodland concert not less impressive than delightful. 



The Wood Thrush used to visit the Fresh Pond Swamps at its seasons 

 of migration, when I have also repeatedly noted it in our garden, but I have 

 never met with it in summer much to the eastward of the town centers of 

 Arlington, Waverley and Watertown. Mr. Walter Faxon tells me, however, 

 that on returning to Cambridge about the middle of June, 1896, he found two 

 males established and singing freely near Oxford Street, Cambridge. One was 

 in the grounds of the Museum of Comparative Zoology (usually in the trees that 

 shade the western entrance to that building), the other, not far from the corner 

 of Oxford and Kirkland Streets. Both birds were heard almost daily up to the 

 middle of July, when they became silent, although one of them sang again a few 

 times on the morning of August 2, during a rainstorm. In 1903 a Wood 

 Thrush was again heard singing, on a number of occasions in early summer, 

 near the Museum of Comparative Zoology. It is possible that all three of the 

 birds just mentioned were breeding in the neighborhood of the Museum, but 

 if so their mates and nests escaped observation.
