io6 The Wilson Bulletix — No. 49. 



and their notes were only heard twice on two successive days 

 late in June. "What has become of Dick?" was a common 

 question araong bird friends. 



The Yellow Warbler has always been abundant until this 

 year. Not one was seen or heard, so the Song Sparrows were 

 alone responsible for the young Cowbirds. It was not an un- 

 common sight to see a huge young Cowbird pursuing a Song 

 Sparrow along the wire fence, refusing to be hushed until it 

 had been gorged with food. 



It seemed a little strange to miss both these birds this 

 summer. Heretofore theii presence has been more marked 

 than any other variety on this list. 



The most unique experience of the summer was a morn- 

 ing serenade. All the Bartramian Sandpipers of the creek 

 bottom must have been present. It was barely three o'clock, 

 and their weird, wind-like whistles sounded like music from 

 another planet. 



The Nighthawks did not appear until the middle of Aug- 

 ust, and then in migration for the most part. One bright 

 midday a flock of one hundred were seen flying south at con- 

 siderable height. Near this same spot two years ago, late in 

 August, I counted six hundred Nighthawks in a space of 

 fifteen minutes. It was about six o'clock in the evening, and 

 the air was just alive with them. The area in which I counted 

 was not more than a quarter of a mile in width, and it was im- 

 possible to estimate the actual size of the wave. It was a con- 

 tinuous passage — -there was no looking back on their part — 

 and standing in an open tract in the woods, I was able to 

 count those in my range with some degree of accuracy. 



Here is the summer list in the order in which they were 

 seen or heard :
