THE MIGRATION OF BIRDS. 



It is always interesting to

 winter and the departure of

 have nested with us. A 

 " bird calendar," as shown 

 below, though intentionally 

 somewhat meagre in itself, 

 may form a basis for many 

 detailed notes and records. 



The entries for a week, say, 

 in the first year of observa- 

 tion, may be written upon a 

 single page, and those for a 

 corresponding period in the 

 next and folio wing seasons can 

 be inserted into the note-book 

 (see page 4) so as to be readily 

 available for comparison. If a 

 complete calendar in the style 

 of the one given has been 

 carefully kept, much accurate 

 information will have been gained as to the appearance and de- 

 parture of our regular migrants. That is to say, of those kinds of
