FALCO COLUMBARIUS : PIGEON HAWK. II7 



the particular localities to which it happens to resort 

 to breed. Mr. Allen cites it for Massachusetts as a 

 " rare resident ; more common in winter than in sum- 

 mer, and along the coast than in the interior." Its 

 breeding in Connecticut, where, however, it is not a 

 common bird, has already been noted. Mr. N. C. 

 Brown has lately instanced the only case of its occur- 

 rence near Portland, which has come to his knowledge.

According to Dr. Brewer, this spirited little falcon is 

 a migratory visitant in Southern, and a summer resident 

 in Northern New England. Dr. Coues says : " Gener- 

 ally distributed, not abundant ; resident ; breeds at least 

 as far south as Massachusetts. Individuals are of general 

 occurrence throughout New England." Mr. J. N. Clark
