THE | WILSON WARBLER. 193 
sary to add that they were placed, the one in an oak and the other in an alder 
sapling, at a height of about two feet from the ground. In feeding the young 
in the Sugar Grove nest the parents would invariably appear upon a certain 
bare twig some fifty feet above; here, if observed, the bird would chirp ap- 
prehensively for a minute or two, and then without further precaution launch 
straight for the nest. 
The Hooded Warbler is possibly on the increase. I have seen it twice 
at Columbus and twice at Oberlin within three years, but have not suspected 
ii of nesting at either place. Mr. Robert J. Sim reports it as a regular 
breeder in Ashtabula County, while Rev. W. F. Henninger reports it as rare 
in Scioto County in summer.
