of which were Sharp-shinned {Accipitcr velox). On this day I 

 saw no less than twelve Bald Eagles i^Haliaetus leiicocephalus) in 

 various plumages flying over New Haven, soaring slowly towards 

 the southwest. 



Again, during the autumn of 1893, I made careful observations, 

 but found few hawks passing until the 20th of September, when 

 quite a flight occurred. This time I obtained two Broad-winged 

 Hawks, a Sparrow Hawk, and a Pigeon Hawk [Falco coliim- 

 bariiis), and although I could have shot many young Sharp- 

 shinned Hawks, which were very abundant, I refrained from 

 doing so. Early on the following day, the 21st, there appeared a 

 flock of about twenty-five Broad-winged Hawks circling low 

 over the city of New Haven. I hastened out with my gun and 

 soon stood in a position favorable for observation, where I saw 

 hundreds of them, and secured eight beautiful adults with the 

 greatest case. I even took a selection of plumage, as the birds 

 passed a few yards overhead, battling against the strong wind 

 which blew from the northwest, as they flew along the coast. 



Last year (1894), I was unable to take observations, but I have 

 made inquiries, and have been told that no large flight occurred. 



The following is a list of the Falconida; found in Connecticut 

 and the frequency of the appearance of the various species in the 

 autumn ' flights ' in the southern part of the State. 



Circus hudsonius. iSL-vrsh Hawk. — Common summer resident. 

 Breeds, abundant in 'flights.' 



Accipiter velox. Sharp-shinned Hawk. — Summer resident. Breeds, 

 sparingly late in May. Exceedingly abundant in September. 



Accipiter cooperi. Cooper's Hawk. — Occasionally seen in winter. A 

 common breeder, and fairly abundant in ' flights.' 



Accipiter atricapillus. American Goshawk. — Rare migrant late in 

 the fall. 



Buteo borealis. Red-tailed Hawk. — Common resident. Seldom 

 breeds near the sea coast. Small flocks are often seen about October i. 



Buteo lineatus. Red-shouldered Hawk. — Resident. Breeds abun- 

 dantly, but is never common in ' flights.' 



Buteo latissimus. Broad-winged Hawk. — Summer resident, but 

 breeds sparingly. Very regularly abundant in ' flights ' from the middle 

 to the last of September. Thousands pass nearly every fall. This species 

 is common in northern New England, and parts of Canada during the 

 surnmer.
