i56 COCKNEY BIRD TRIPPERS 

 chirps become sweeter, resembling the 

 silvery spink spink of their gay cousins. 



The sparrow has the power to produce 

 sweet notes, but in the rush of a big city he 

 has become careless regarding his personal 

 appearance, his song, and the construction 

 of nest. 



About the second week of September the 

 bird trippers come back, their voices clearer 

 and their feathers sprucer. After a while, 

 however, they return to their old habits, 

 quarrelsome and untidy as before.
