near West Chester (Chester county.) At that time they had constructed about four or 

 five nests. Yesterday, June 12, 1 again visited the locality, and after searching about 

 twenty empty nests, at last came ujDon the right one, containing six eggs. They had 

 probably been sat on several days, but I secured them with the nest. * * * 

 I do not think there is more than a single pair in the locality, but it seems incredible that 

 they should make so many nests."
