 "chirped" to describe the peculiar squeaking sound uttered 

 by the young waxwings. 



B. Periods of Nest Building. 



On July 9, 1916, we noticed a cluster of needles and string 

 on a pine limb so placed that we thought it the beginning of

 When we arrived the second bird was standing within the 

 nest and seemed to be weaving the inside with its bill. The 

 first bird was on a nearby limb and at 8 :25 it chased away
