THE BIRDS' TIME-TABLE 



hear them chattering happily about the houses 

 we have offered them as homes. 



Some morning about April 25, when we open 

 our windows to the warm sun rays, the House 

 Wren will greet us with his merry little trill. 

 He is bobbing in and out of a bird house per- 

 haps the very one he nested in last year. 



A Catbird sings from the heart of a lilac bush, 

 while from the topmost branch of some tall tree 

 the Brown Thrasher, in loud, ringing notes, tells 

 us that he is home again. 



That evening we may hear the twittering of 

 Chimney Swifts just back from Central Amer- 

 ica, and see their bow-and-arrow-like forms sail- 

 ing overhead. 



The army now is moving rapidly and with 

 closed ranks. Company after company hurries 

 by; others stop to camp with us. It is an exciting 

 time for us on the lookout. Sharp indeed are 

 the eyes and keen the ears that see and hear all 

 that is to be seen and heard. Between May 7 

 and 12, when the migration is at its height, as 

 many as one hundred and forty different kinds
