The ogjf.s vary from 5 to 7 in iiuinhor, usually 5, and aro ilvad 

 white in ground color, well sprinkled with fine specks and small 

 blotches of reddish brown, and less numerous and conspicuous 

 lilac markings, more thickly about the large end, where, in perhaps 

 a third of the specimens, they tend to form a wreath. Three sets 

 measure as follows, in hundredths of an incli: 

 No. 1. .()() X .50; .02 X .17; .()4 X .47; .(12 X .47; AV2 X .47; 



.62 X .47. 

 No. 2. .(Hi X .52; .()5 X .51; .(57 X .52; .()4 X .51; .70 X .50. 

 No. 3. .()4 X .49; .().S X .49; .()5 X .47; .()2 X .45; .()3 X .47. 



The males sing most persistently, and at all times of day, and 

 as they sing from some perch, usually lofty, within a few roils of 

 the nest, they give a good clue to its general location. 



The song, though (iuit(> characteristic, is ratiicr dillicult to 

 describe. In fact, the authors finding this beyond tlu>ir powers, 

 appealed to Mr. Louis Agnssiz Fuerte.s^ who kindly furnished the 

 following notes: 



"1 would not recognize" it iiniong other ' Vermivora>' by its '(;hip,' 

 but I usually spot its .'foiuj, which to my car is represented as ' Xee', 

 Xee', Xee' see', sec', see' see'-e-e-e-e- " or K'sec'-K'see', xee', 

 xee', see' see' sce'-e-e-e-e-.' It is done in a thin or wiry (luality 

 of tone, high, like a Nashville's, and is the only Warbler song I 

 know that is a consistent accelerando from end to cm], all on tiie 

 same pitch. Though wiry, it is frecjucntly ((uite loud, and may be 

 heard for some distance'. It may — and proI)ably does — have 

 more elabonitcd songs for the period of early sununer, which 1 

 have never heard." 



As a basis for estimating the frequency of .song repetition, 

 counts were kept on three singing birds for a period of fi\'(! minutes 

 each, with a result of .'i2, 'M) and 22 songs, respectively, within the 

 period. In one instance, a bird was observed to sing wliih^ on the 

 wing, repeating the song twice in the course of a short flight. 



In addition to the birds of the ten nests obse-rved, at least a dozen 

 males were heard singing in other localities within a radius of four 

 or five miles. The Tennessee Warbler would appear to be one of 

 the most mnne^rous warblers of this part of New Brunswick, 

 while the two nesting records of the Nashville Warbler in 1914
