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.
