Middlesex County, Mass. 1872 March 30, Apr. 3 Concord River. did not find a single typical islandica among them nor indeed any approach to that type. Out of the whole number at least 9/10 even adult males some of them however showing traces of bronze on the green of the head; the other 1/10 were mostly opacutera shades with only one or two o. One examining a large series of females in another lot from this State I found some with terminal bend bronilla without band or great courts; others with with the dusky yellow bill of B. Americana had the courts banded quite conspicuously. Mar. 30 Attended a picnic at Concord last night, starting with the P's. After breakfast strolled down to the river and heard the first full spring chorus of red notes Blue birds, Regilbins pheo. Sol. turdigenius and Molesthus proving the last two new arrivals. Saw also a flock of Sheldraks at the boat lady fishing in the river. April 3. A lovely spring day warm and sunny. Took first track to Concord taking my br. walk. Started immediately for the bird path dawn. At the first bend found three Sheldraks & two Blacks and brushed the boat for them but the latter were too shy for us and they all went off before we got within shot. Then kept down river half a mile when we saw six Whistlers and B. littoralis pair of Ayl Sponsa at a short dropping over brush boat down on them with the current. Dan, also pulled a small hawk which fell across the air and was lost. Drabs wounded a Sparrow that looked very like Centronyx Bairdi but far too to get at. Then kept down stream to about a mile
