Green, Greenish Gray, Olive, and Yellowish Olive Birds 
In the Delaware Valley and along the same parallel, this 
inconspicuous warbler is abundant, but north of New Jersey it 
is rare enough to give an excitement to the day on which you 
discover it. No doubt it is commoner than we suppose, for its 
coloring blends so admirably with its habitats that it is probably 
very often overlooked. Its call-note, a common chirp, has noth- 
ing distinguishing about it, and all ornithologists confess to hav- 
ing been often misled by its song into thinking it came from the 
chipping sparrow. It closely resembles that of the pine warbler 
also. If it were as nervously active as most warblers, we should 
more often discover it, but it is quite as deliberate as a vireo, 
and in the painstaking way in which it often circles around a 
tree while searching for spiders and other insects that infest the 
trunks, it reminds us of the brown creeper. Sunny slopes and 
hillsides covered with thick undergrowth are its preferred foraging 
and nesting haunts. It is often seen hopping directly on the dry 
ground, where it places its nest, and it never mounts far above it. 
The well-drained, sunny situation for the home is chosen with 
the wisdom of a sanitary expert.
