Inderøen (64°), the most northern locality in which it is known to 

 occur. It very probably, however, ranges farther north. 



A nest was found in the district of Ørkedalen, near Trondhjem, 

 April 25th 1872. It was built about 8' from the ground, in the 

 hollow stem of a Populus tremula. The female was tåken sitting 

 on her eggs, which were five in number and in anadvanced stage 

 of incubation. In 1871, a nest with 5 eggs had been was found 

 in the same stump. 



In the stomach of an individual shot near Christiania in Oet. 

 1871 (Total length 248 mm; wing 177, tail 103 mm), I found a 

 Sorex vulgaris. 



Syrnium lapponicum, Thunb. 

 Almost every year an individual of this species is killed here 

 and there in the south of the country, where it has occurred on 

 the Hvaløer (islands), near the Swedish coast. A female, emaciated x 

 and apparently sterile, was shot near Christiania, towards the end 

 of March 1870. 



As a breeding bird, it is doubtless confined to the wooded 

 districts along the Swedish and Russian frontier in Nordland and 

 Finmark. In East Finmark, it has been found several times of late 

 years, the last time in the summer of 1866. 



Syrnium al ti co, Lin. 



Ranges north as far as Salten (67°), and is not rare throughout 

 the whole of Nordland. 



From nests containing young (Christiania, May Ist 1871), I took 

 the following remains of the food which the old birds and the 

 nestlings had been partaking of: — 



Mus sylvaticus: an individual with the head gone (it was 

 found entire in the stomach of a nestling scarcely five days old), 

 and numerous fragments. Arvicola agrestis: a few individuals entire, 

 and the fragments of a dozen. Arvicola amphibius : the whole of 

 the cranium, in three parts. Arvicola glareola: a few individuals. 

 Sciurus vulgaris: the cranium and other bones. Sorex vulgaris: 

 numerous individuals. Rana, sp: parts of one individual. Tur dus, 

 sp: fragments. A small bird of another species: fragments.
