 feed in company with the Black Ducks. The Pintails are more common in the Southern 

 States but the great winter resort of the species is in Florida; here they are not only ex- 

 ceedingly abundant but very tame. On one occasion, while I was making my way down 

 Indian River, numbers of these Ducks were passing over my head southward. They flew 

 in .strangling flocks, consisting of from twenty to some hundreds of specimens, and one com- 

 pany followed another so closely, that there \vas an almost unbroken line. They contin- 

 ued to move in this manner all tho morning; thus many thousands of individuals must have 

 past us. Shortly after noon, they began to alight along f,he beaches in such numbers that 

 they fairly covered the ground, and were so unsuspicious that my assistant, who had left 

 the boat sonic time previous, walked within a few yards of them, and killed three or four
