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 inter- 
esting and valuable instruction during your leisure time.
