PERMANENT RESIDENTS 37 



largely upon the mildness or severity of the season. Should the ponds 

 and streams remain open, the ground be unfrozen, and little or no 

 snow fall, many of the migrant species of November will linger into 

 December. They rarely are found, however, after the middle of the 

 month, when our bird-life is again reduced to its simplest terms of 

 permanent residents and winter visitants. 



Similarity of feeding habits now brings certain species into loose 

 bands whose movements are governed largely by the presence or 

 absence of food. Their wanderings may lead them over large areas, 

 and our orchards and dooryards may now be visited by species which 

 will eagerly partake of our bounty. Crumbs and seeds will bring 

 Juncos, Tree Sparrows and Purple Finches; an old seed-filled sun- 

 flower head may prove a feast for Goldfinches, while bits of meat, 

 suet, or ham bone will be welcomed by Chickadees, Nuthatches and 

 Downy Woodpeckers. (On this subject of winter feeding consult the 

 publications of the National Association of Audubon Societies.) 



The flight of Crows to and from their roosts is one of the charac- 

 teristic sights of the bird-life of this season. 



This outline of changes in the bird-life of the year occasioned by 

 migration, may be summarized by presenting a list of the commoner 

 permanent residents of the vicinity of New York City and adding 

 chronological tables of migration.
