1 82 SINGING BIRDS. 



tic, more than loo feet from the ground. At other times they 

 are not more than 50 to 70 feet high. The only nest I have 

 been able to examine was made externally of flat and dry 

 sedge-grass blades, for which, as I have observed, are occa- 

 sionally substituted strings of bass. These dry blades and 

 strips are confined and tied into the usual circular form by 

 caterpillars' silk, blended with bits of wool, silk-weed lint, and 

 an accidental and sparing mixture of vernal grass tops and old 

 apple-blossoms. It was then very neatly lined with the small 

 flat blades of the meadow grass called Poa compressa. 



This species is rather uncommon in the Maritime Provinces 

 excepting near the Maine border in New Brunswick, and in the 

 more southern portions of Nova Scotia. It is fairly common in 

 southern Quebec, and abundant in Ontario. In parts of New 

 England and the Middle States it is a common summer resident. 

 At the West it ranees north to the fur countries.

These common and indefatigable songsters appear to inhabit 

 every part of the American continent, from Labrador to the 

 large tropical islands of Jamaica and St. Domingo ; they are 

 likewise resident in the mild tableland of Mexico. Those 

 individuals who pass the summer with us, however, migrate to 

 the warmer regions at the commencement of winter, as none 

 are found at that season within the hmits of the United States. 

 The Red-Eyed Vireo arrives in Pennsylvania late in April, and 

 in New England about the beginning of May. It inhabits the
