TABLE lY— August 3 



General Remarks on Table IV 



The observations on this date covered the time between 8 :55 

 and 11 :00 a. m. and 3 :05 and 5 :06 p. m. during which twenty- 

 six feedings were administered. 



The male usually announced his arrival by a low trill and 

 as soon as the brooding female heard it she left the nest. Al- 

 most immediately after feeding the young he flew away again. 

 This behavior was fairly constant throughout our observations. 



The foregoing table shows a greater variety of food brought 

 to the nestlings than heretofore.
