290 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



272 [652] Dendroica aestiva (Gmel.). 

 Yellow Warbler. 



Abundant summer resident ; May 2 to September 26 ; average date of 

 arrival for six years, May 3 to 4. 



Eggs: May 27 to June 13. 



Although generally a bird of gardens and orchards near houses, the Yellow 

 Warbler is very common in the wooded islands of the Wenham and Topsfield 

 marshes and adds its very varied songs to the confusing chorus of warbler 

 voices to be heard in that region. It nests there on the edges of the woods in 

 bushes sometimes overhanging the waters of the Ipswich River. 



273 [654] Dendroica cserulescens (Gmel.). 

 Black-throated Blue Warbler. 



Common transient visitor ; May 1 1 to May 24 ; September 27 to Octo- 

 ber 8. 



There is no neater and more strikingly beautiful bird than the male Black- 

 throated Blue Warbler, and none more demurely and obscurely dressed than his 

 spouse. His song is loud, searching, and hurried. I have heard the same bird 

 sing ti-ec tree tree trreep and a little later wheet wlieet wheet wheee. 



274 [655] Dendroica coronata (Linn.). 

 Myrtle Warbler ; Yellow-rumped Warbler. 



Abundant transient visitor, not uncommon winter resident ; August 19 to 

 May 2 1 ; average dates of migration, April 1 7 to May 1 5 ; September 20 to 

 November i. 



The August dates are probably of early migrants, although my earliest 

 date, August 19th, 1878, records an adult female with breast devoid of feathers 

 as if recently incubating, shot in some bushes near the ocean at Magnolia. 



The interesting fact about this Warbler is that at the present day, at least.
