Black-throated Blue Warbler {Dendroica ccerulescens cwrulescens) 

 Nesting in Sterling, Massachusetts. — I have been collecting about 

 Lancaster, Mass., since 1897 and I have never found but one Black- 

 throated Blue Warbler's nest until today. 



My friend Mr. Herbert Parker told me he had found what he was sure 

 was a Black-throated Blue's nest, in Sterling, which is the next town to 

 Lancaster, about due west. I went with him the next day (May 28, 1911) 

 and found the nest with the female on it. She ghded off and I shot her, 

 to be absolutely sure about the identity. The nest was placed in a laurel 

 bush ( Kalmia latifolia) about eleven inches from the ground and contained 

 four fresh eggs. It was a typical nest of this species, Kned with the dark 

 fibres that are usually used. 



Later in the day we found another nest, in a laurel bush, about two feet 

 from the ground. It contained four eggs shghtly incubated. As the 

 female was very tame and gave us every opportunity to identify her, 

 I did n't shoot her, as it seemed unnecessary; especially as I had collected 

 the parent bird with the first set. 



I located another pair in this same wood, but failed to find their nest. —
