72 The Wilson Bulletin — No. 83. 



vations includes the whole of the townships of West Milford 

 and Pompton. The country consists mostly of low rolling 

 hills, heavily wooded, intersected by broad valleys, in whose 

 precincts are located the farming- districts of the section. Dot- 

 ted here and there are many small ponds and lakes, the prin- 

 cipal of which are Echo Lake, Mud Pond, Pompton Lake and 

 the lower half of Greenwood Lake. Most of the ponds and 

 lakes are connected by small streams and rivers, form.ing a 

 network over the whole of the district canvassed. In the west- 

 ern half are located the Bearfort Mountains, the highest in the 

 section. These range from 600 to 1,400 feet in elevation and 

 are heavily wooded with an original growth which covers more 

 than three-quarters of their slopes. At the southern end of 

 this range is located the Kanouse Mountain, another heavily 

 wooded hill, but much lower in elevation. Along the south- 

 ern border the Pequannock River meanders nearly the whole 

 length of the section and separates these townships from 

 Morris County, their southern neighbor. 



But little has ever been written or published regarding the 

 ornithology of this section, and it has been the object of the 

 writer to gather together an authentic as well as a complete 

 record of each and every species present, together with notes 

 on those which breed and rear their progeny with us each 

 year.
