214 The Passenger Pigeon 



The places where the birds are nesting are interesting 

 spots to visit. Both parents incubate and the scene is 

 animated as the birds fly about in all directions. How-

 birds will settle on a hmb which holds nests and then 

 many eggs are dashed to the ground, and beneath the
