THE SYCAMORE WARBLER. 159 
with a piercing quality like that of the Yellow Warbler. Rev. W. F. Hen- 
ninger, 1902, gives the bird as a “rare transient * * * observed in 
Scioto County only;’ while Raymond W. Smith (1891) reported it as a 
common migrant in April in Warren County. 
It is more than probable that the decrease in numbers in the case of this 
species is due solely to the continued destruction of the sycamore trees. Here. 
at least, is a bird rightly named, for the Warbler has cultivated this grim 
and grizzled old man-of-the-rivers—whom all the other birds, save perhaps 
the Blue-gray Gnatcatcher and the King-bird, seem to shun—until its de- 
pendence upon it is almost absolute. That the bird was formerly not un- 
common northerly is 
abundantly attested, 
and it may be that it 
can still be found in 
favored spots. Mr. 
Jerome Trombley 
knew it as a rate 
summer resident 
along the River 
Raisin, in Monroe 
County, Mich., and 
in 1880 succeeded in 
locating a nest. It 
was placed 60 or 70 
feet high in a syca- 
more tree and at the 
end of a _ branch, 
some 20 feet from 
the trunk. Inasmuch 
as the tree was seven 
feet through at the 
base and the sup- 
porting limb did not 
promise to support 
above a fifty pound 
weight, the discov- 
erer deemed thc 
treasure —_ unattain- 
able. In 1897 the 
same observer noted 
only one bird. Un- Taken near Cincinnati. Photo by the Author.
