YELLOW-BILLED CUCKOO

(Lake Forest) 



A PRIL 29, 1901. Had a fine view of 

 -*1 this bird in a bare tree. How rufous 

 his wings are and his bill looks as if it 

 were all yellow and not just the lower 

 mandible, at least it looks so in the sun. 

 No notes from this bird today. I wish I 

 could tell his notes from the black-billed. 

 Was it this bird that has been giving a low 

 coo at intervals for several days? (July 

 31, 1901) or the black-billed? I could 

 only see that it was a cuckoo, not a bittern 

 as we first thought. He keeps this cooing 

 up 'for hours ; so different from his loud 

 cow-cow-cow-ing.
