Dusky, Gray, and Slate-colored 
Spanish or Usnea ‘‘ moss” drapes itself over the cypresses, as it 
can find here at the north. Its rarely beautiful nest, that hangs 
suspended from a slender branch very much like the Baltimore 
oriole’s, is so woven and festooned with this moss that its con- 
cealment is perfect.

sparrow.

darkest on lower back. Wings and tail edged with bluish. 
Cheeks, chin, throat, upper breast, and sides black. Breast 
and underneath white. White spots on wings, and a little 
white on tail.

spots inconspicuous. Tail generally has a faint bluish tinge.

Whoever looks for this beautifully marked warbler among 
the bluebirds, will wish that the man who named him had pos- 
sessed a truer eye for color. But if the name so illy fits the 
bright slate-colored male, how grieved must be his little olive- 
and-yellow mate to answer to the name of black-throated blue 
warbler when she has neither a black throat nor a blue feather! 
It is not easy to distinguish her as she flits about the twigs and 
leaves of the garden in May or early autumn, except as she is 
seen in company with her husband, whose name she has taken 
with him for better or for worse. The white spot on the wings 
should always be looked for to positively identify this bird. 
Before flying up to a twig to peck off the insects, the birds 
have a pretty vireo trick of cocking their heads on one side to in- 
vestigate the quantity hidden underneath the leaves. They seem 
less nervous and more deliberate than many of their restless family. 
Most warblers go over the Canada border to nest, but there 
are many records of the nests of this species in the Alleghanies 
as far south as Georgia, in the Catskills, in Connecticut, northern
