The Short-eared Owl (Brachyotus Cassinii) probably 

 also occurs, but I have never obtained any specimens. 



SYBNIUM CINEREUM, Aud. Great Gray Owl. Winter visi- 

 tant. Very rare. 



S. NEBULOSUM, Gray. Barred Owl. Resident. Common. 

 Breeds. 



NYCTALE ACADICA, Bon. Saw-whet Owl, Little Owl. Resi- 

 dent. Common. Breeds. 



NYCTEA NIVEA, Gray. Snowy Owl. Winter visitant. Not 

 common. This species is very gentle and becomes tame 

 very readily in confinement, differing greatly in this 

 respect from the Great Horned Owl. 



SURNIA ULULA, Bon. Haivk Owl. Autumn and winter. 

 Common. This species is quite common from the first 

 of November to the middle of March. I have never seen 

 it in summer. 



COCCYGUS AMERICANUS, Bon. Yelloiv-billed Cuckoo. Sum- 

 mer visitant. Not common. I have never found nests of 

 this species at Norway, although it probably breeds there. 



C. ERYTHROPHTHALMUS, Bon. Black-billed Cuckoo. Sum- 

 mer visitant. Common. Breeds. Much more common 

 than the last. Have not observed it before the 20th of 

 May. 



Picus VILLOSUS, Linn. Hairy Woodpecker. Resident. 

 Very common. Breeds. 



P. PUBESCENS, Linn. Downy Woodpecker. Resident. Yery 

 common. Breeds. The young remain in the nest until 

 the last of July or first of August, and are then fully 

 grown. 



PICOIDES ARCTICUS, Gray. Black-backed Three-toed Wood- 

 pecker. Spring, fall and winter. Very common. This 

 species is abundant from the middle of October to the 

 middle of March. Have never seen it here in summer. 



SPHYRAPICUS VARIUS, Baird. Yellow-bellied Woodpecker. 

 Summer visitant. Common. Breeds. Arrives about 

 the middle of April. This is the true " Sap Sucker" 

 which injures apple trees, though the Downy Woodpecker 

 is too often unjustly punished for it.
