earliest record for finding a full nest complement, which was 

 on the 14th of May, and consisted of four fresh eggs. My latest 

 record for eggs is June 13th, three of the Warbler and one 

 of the Cowbird, all slightly incubated. These should have 

 hatched out in seven days. Thus it would appear that Mav i<; 

 and June 20 are extreme dates for the female to brood her 

 eggs. 



Song, Food and Young. 



The song period begins upon their arrival from the South, 

 and continues throughout the nesting season, which owing to 

 weather interruptions, and annoyances by domestic animals, 

 extends throughout May and June. 



While the female is incubating the eggs, her mate moves 

 about the tips of branches and tops of saplings, searching for 

 food, all the while singing his little ditty, which is a simple 

 little bit of bird music hard to put into print. At some dis- 

 tance the song can be distinguished by the svlables "Zee-ze- 

 ^e-ze-ze," beginning slowly and proceeding more rapidly, en. Is 

 in a slightly higher pitch. When near the bird this song 

 sounds somewhat different, and now is when it is hard to 

 imitate in type. The best I can do is to write it zee-u-ee'— 

 zee-u-ee' — zee-u-ee' — zee-u-ee' — zwee', with the "u" barely ar- 

 ticulated. 



I have several times heard the song continued to the mid- 

 dle of July, and again on still sultry days in August. At this 

 time, however, it is not so strong and complete as during the 

 early summer. While emitting this song, the bird stands quite 

 erect, stretched up to its full height, throat extended until 

 the feathers ruffle. The head pointing about 70 degrees 

 upward when the first syllable is uttered, is turned farther up- 

 ward at the close of the song.
