UNEQUAL WING-STROKES IN FLIGHT. 



The photographs here reproduced sliow that, when a Pigeon 

 flies the two wings are not always in corresponding positions, 



but that they sometimes, 

 for steering or balancing 

 purposes, give unequal or 

 different strokes. 



In Figure 1 the Pigeon 

 is in very liurried flight. 

 The riglitwing is raised and 

 the left wing is lowered. 



In Figure 2 the lower 

 bird on the right is just 

 starting to fly from the 

 window-ledge.
