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.
