BIRDS 31 



ol New York (Chapman), and " winter visitants," seventeen 

 species of birds that come from the north and spend part or 

 all the winter. 



Make provision for the winter birds. Suet and a piece of 

 fat pork may be tied to a branch of a tree, with a tray also 

 fastened to the trunk, in which seeds (millet, corn, sunflower, 

 pumpkin, or squash) and cracked nuts (butternuts are espe- 

 cially good) may be kept, and on the ground close by a pile 

 oi chaff or loft sweepings. The purpose of this is to attract 

 all the winter birds within range of easy observation. The 

 tray may be attached to the living-room window sill, if on the 

 south side of the house, an attractive branch may be fastened 

 at the side of the window, and the heap of chaff may be put 

 under it, close to the house. This latter must be kept free 

 from snow through the winter. 



The work of the year is intended to yield a complete pic- 

 ture of the life and work of the birds in your district. At 

 stated intervals your observations should be carefully written 

 up under various heads. We suggest the following :
