WARBLERS 527 



bark and lined with hair and fine grass. It is two and a half 

 inches deep outside by one and three-fourths inside, while the 

 diameter outside is three and a half and inside one and a half 

 inches. The eggs measure 0.65x0.51, 0.69x0.53, 0.64 x 

 0.51, 0.66 X 0.53. The eggs may be found from May thirtieth 

 to July first, usually about June fifteenth. The following 

 notes on this species are taken from an article written by Mr. 

 Swain for the Journal of the Maine Ornithological Society, 

 1899, p. 33. 



"At our last annual meeting, as I was introduced to our edi- 

 tor, Mr. Morrell, he remarked, ' You are the fellow who can 

 find the nest of the Black-throated Green Warbler.' And so, 

 later in the day, I promised him I would write an article on 

 this Warbler, at some future time, giving the modus operandi 

 of finding its nest. 



I remember well this most interesting Warbler, as I used to 

 watch it, busily feeding about the foliage of the trees, in the 

 woods near my old home, when but a child. And oft did I 

 wonder what was the name of this bright, beautiful bird, with 

 the patch of black on its throat, always so busy, and ever and 

 anon giving utterance to its pleasing song, which once heard 

 is not to be forgotten, and is not like that of any other War- 

 bler. As a child I tried to English it, and it said to me, 

 ' Nee-nee-nee-du-dee.' This leisurely, the first three syllables 

 on the same pitch, the fourth one tone lower, and the fifth one 

 tone lower than the fourth. Then at times, it would quicken 

 its tone to ne-ne-ne-ne-ne-du-dee. The first five at the same 

 pitch of voice, then lowering the last two as before. 



Then at times, when leisurely feeding, it would say in a 

 drawly tone, and pitched several tones lower than the above 

 two songs, de-de-de-du-dee. The first two syllables slowly and 

 at a low pitch, the second slightly lower than the first, the last 

 three slightly quicker, raising the tone on the fourth note and 

 dropping back to the same pitch on the last. It is a very 

 pleasing song to me, and one that has brought a deep sense of
