 or species of sparrows, hawks, and ducks, but the 

 several species in each of these groups have " a family

 Now there are not so many of these groups but that 

 one can give a distinct idea of each without too great 

 effort. Then, when a bird is clearly seen, one will 

 have a pretty good idea as to where it belongs, and 

 will only have to compare descriptions of a few species 

 to find the right one. 



There is a great difference in the state of mind of 

 the person equipped with this knowledge who tries to 

 identify birds and that of another who encounters the 

 birds afield without it. I recall most vividly my first 

 meeting, when a boy, with a certain common bird, and
