seemed to be catching grasshoppers. I do not know what else he could be 

 after by the way he ran around and would fly a few feet and light again. 

 It was after something, whatever it was. I could not approach it as I was 

 in plain view so I let it work and it flew into the woods after about 25 

 minutes of flapping and running around. I have not seen any mate as 

 yet. Mosher [one of his sons] saw the bird yesterday [July i6th] while 

 I was from home and he said it lit on a tall pine and sat there for a full 

 hour and then took a sail in the air and went out of sight behind some trees. 

 I am watching its movements and will write you again." 



In 1900 Mr Haight saw three more kites on June 9, and noticed one 

 about his place until June 19. All of this evidence would seem to indicate 

 that the Swallow-tailed kite has established a home in Rensselaer county, 

 N. Y., but absolute evidence of its breeding in this State is still lacking.
