hawks, but could not obtain the other one. He 

 kindly sent me the one shot, which was a beautiful 

 male specimen, but unfortunately by the time it 

 reached me it was too much decomposed to have 

 the skin preserved for my collection. 



Subgenus "^Esalon." Kaup. 



111. Pigeon Hawk. F. columbarius. Linn. 



" Transient Visitant," scarce. I have frequently 

 observed this little hawk in the autumn, when out 

 shooting, and on one occasion I saw in the spring 

 of the year at Laprairie a large flock of Snowflakes 

 (Snowbirds) depart very suddenly for pastures new, 

 on the appearance of a pigeon hawk flying swiftly 

 a few feet above the ground towards them. I shot 

 an immature male specimen of this hawk Septem- 

 ber 1, 1892, on Jones' Island, in Lake of Two 

 Mountains. 



Subgenus " Tinnunculus." Yieill. 



112. American Sparrow Hawk. F. sparverius. Linn. 



"Summer Resident," scarce. More common in 

 the spring and autumn. I shot a pair of these 

 beautiful little hawks May 10, 1884, at Hochelaga. 

 I have seen them here April 7 and in the autumn 

 as late as October 12.
