FIELD SPARROW 117 



namely, in 1901, 1903, and 1906. In 1902, 

 1905, 1907, and 1908 there were several 

 successive visits of a single bird at inter- 

 vals of a few days. The earliest appearance 

 was of a bird in song on the Common, 

 March 31, 1902; the next earliest time of 

 arrival was on April 9, 1903, in the Garden. 

 The latest records have been of a bird on 

 May 16, 1905; of one on May 13, 1906; 

 and of two on May 13 and 14, 1907. The 

 period of migration covered thirty-two 

 days in 1902 and 1905. Several of the vis- 

 itants have sung. 



The Field Sparrow also was found in 1907 

 to have a preference for the Common. The 

 first two records of the season were there 

 obtained, namely, on April 21 and 26, on 

 the latter date there being three birds pre- 

 sent which remained to the following day. 

 In 1902 one bird continued there in song 

 during four days, March 31 to April 3, 

 singing each morning in the vicinity of the 

 burying-ground. 



No autumn records of the species have 

 been obtained.
