The Singing- of Birds. B.P.B^cknelL 



Dendroeca aestiva. Summer Warblek. 



Sings from its arrival in late April through July, but usually 

 with diminished frequency toward the end of the month, although 

 in some years it continues in full song nearly until mid- August. 

 Ordinarily singing ceases in the second week of August ; rarely 

 earlier, but sometimes later. Extreme dates are August 4, 5, 

 and 9, and August 18 and 19. This is the season of the bird's 

 departure. Axik. I, July, 1884. p.

70 Dendroica estiva. Yellow WARBLER.-Abundant everywhere 

 below 2800 feet, especially in willows and sycamores along the banks of 

 streams. Throughout the region its song was very different from that of 

 our northern bird and bore a much closer resemblance to the song of the 

 Nashville Warbler, for which, indeed, I at first mistook it.

I As 



to incessant singing, I tliink the Yellow 

 Warbler deserves the laurels. All day long, 

 or nearly so, it keeps up its pleasing tune at 

 the rate on an average of six vocal perforn 

 ances every minute. I have had opportunity 

 lately to notice the singing of an individual 

 Yellow Warbler and I find that every ten 

 seoond.s, on an average, he rolls out his ditty; 



liout the day. Now
