of course, noting any peculiarities of any bird that you may see, select some 

 particular one or ones and find out all you can about it. The following most 

 necessary points are cited to aid the student in making observations : Date of 

 arrival and whether in large flocks, pairs or singly ; where found most abundantly ; 

 upon what do they feed at the different seasons ; what are their songs and calls 

 at different seasons ; when and where do they make their nests ; of what are they 

 made and by which bird or both ; how long does it take, and when is the first and 

 last egg laid ; how long does it take them to hatch, and do both birds or only one 

 incubate them ; upon what are the young fed at different ages ; how long do they 

 remain in the nest, and do they return after once leaving ; how long before they 

 are able to feed themselves, and do they remain with their parents until they 

 migrate. These and other notes that will suggest themselves, will furnish in- 

 teresting and valuable instruction during your leisure time.
