disposed to act on the offensive. I had a fine red-shouldered, hawk in the same 

 aviary, which the o\\] killed and ate the socoml night. 



Bubo subarcticus, Hoy. 



This winter vistor I consider closely allied, yet distinct fr6m the common 

 honied owl, and as such it is described in the Proc. Acad. Nat. Sci. vol. vi. 

 paije 211. I have as yet examined but three specimens. The specimen in the 

 collection of the Academy was known to carry off from one farm, in the space 

 of a month, not less than twenty-seven individuals of various kinds of poultry, 

 before it was shot. 



Syrnium cinekku.m, Li)tn. 



Not numerous. 1 have a fine m.ale specimen, shot near Racine, Jan. 4, 1818. 

 A rt^markable peculiarity of thi* specimen was, that the irides were hrilliavt 

 hlood-red. I saw one sieze and carry off a duck on Lake Superior, near the 

 mouth of Cerf river, Sept. 1st, 184-5. 



*SvRNir:\i NEBULOsu.M, Linn. 



Common in the heavy timbered districts. 



*OtUS VULGARIS, And. 



More numerous in the vicinity than any other owl. The young leave the nest 

 about the middle of June. 



*Otus brachyotus, Linn. 



Common on the prairies, where they nest on the ground, in the tall grass. The 

 young are fully fledged by the second week in June. 



*Nycta].e acadica, Gmel. 

 Common. 



Nyctalk Tengmalmi, Gmcl. 



I procured a single specimen near Racine, Nov. 30th, 1850. Not uncommon 

 on the head waters of the Wisconsin river. 



Ny'ctale Kirtlandii, Hoy. 



A third species of this genus, found here, and described in the Proc. Acad. 

 Nat. Sci. vol. vi. page 210. 



Only two specimens have yet been observed. 



Strix flammea, liinn. 



A fine specimen of this handsome owl was obtained this spring by my friend 

 the Rev. A. C. Barry, of this city. It was shot near this city, and is the only 

 specimen which has come under my observation. 



CAPRIMULGID.E, (2 species.) 



*Antrostomus vociferus, Wilson. 



Common. Arrives about th- 1st of May, departs middle of September. 



*Chordeiles virgixianus. Bliss. 



Numerous. They leave us by the 15th of September. On the lOth of this 

 month, 1850, for two hours before dark, these birds formed one continuous flock, 

 moving south. They reminded me, by their vast numbers, of passenger 

 pigeons, more than night hawks. Next day not one was to be seen. 



HIRUNDINID.E, (6 species.) 



*Progxe purpurea, Linn. 

 Common. 



*HiRUXDO AMERICANA, Wilson. 



Numerous. 



*HlRUNDO FULVA, Yieill . 



A few nested for the first time at Racine in 1852. Numerous in many parts 

 of the State.
