THE DAY FLYERS 



Forests we still have, but of the Pigeons not 

 one remains. 



SUGGESTIONS FOR STUDY 



Mention some of the commoner day flyers. Have 

 you ever seen any of them migrating? How far 

 above the earth were they? Were they flying in 

 flocks or singly? Which way were they going? 

 Compare the habits of day flyers with those of night 

 flyers. How do Crows migrate? Have you ever 

 heard birds calling when they were at too great a 

 height to be seen? Is it probable that birds mi- 

 grate during the day at so great a height as to 

 be out of sight? Do traveling birds answer the 

 calls of others of their kind? What are the dif- 

 ferences between a Mourning Dove and a Wild 

 Pigeon? In what part of the country were Wild 

 Pigeons once found; how many did Wilson estimate 

 passed him in four hours? Did these birds nest in 

 scattered pairs like Doves, or in colonies? How 

 large an area is said to have been covered by a 

 single nesting community of Wild Pigeons? How 

 many nests have been seen in a single tree? What 

 causes led to the extermination of the Passenger 

 Pigeons? When was the last one seen alive in 

 nature?
