48 BIRDS OF SWOPE PARK 



SECTION NUMBER 14 



One of the most interesting walks of the whole investiga- 

 tion was the canvass of the Old Rifle Range and the country 

 bordering it. The Rifle Range itself, is a brOad meadow of 

 blue grass and weeds. Bordering it to the east is a still more

Along the Blue River is a strip of dense woods inhabited 

 by Warblers, Titmice and Chickadees. 



The meadow is remarkable for its number of Dickcissels.

 ately count the singers, but a conservative estimate was made 

 by counting the singing birds over a narrow strip and then 

 multiplying this by the number of similar strips included in 

 the tract. This estimate gave fifty male Dickcissels for the 

 whole section which I think is not far from correct.

 stration of his vocal powers. He was truly a great singer, with 

 a wonderful variety of trills and warbles, yet he always kept 

 the peculiar quality of the White-eyed Vireo. The variations, 

 however, were so great that I was obliged to stop and spend
