BIRDS OF THE GRAAKALLEN MOUNTAIN, NORWAY. 
By Rev. Witut1am Serie, M.B.O.U. ) 
Tue Graakallen—a mountain rising nearly 2000 feet in 
height—is a well-known ski-ing resort, six miles south of the 
town of Trondhjem, North Norway. On the top it is bare and 
rocky, but the slopes are covered sparsely with pines, while some 
little lochs lie around the base. On its slopes I lived from May 
18th till June 6th, 1907, and I spent the time wholly studying 
its bird life. Unfortunately for my purpose the season was an 
abnormally late one, and whilst at the beginning of my stay 
birds were scarce, when I left they were becoming abundant in 
every spot—I only saw one Willow-Warbler at Trondhjem on 
May 11th; by the beginning of June they simply swarmed on 
the Graakallen. I seemed to think the migrant birds that 
gradually ascended the hill-slope did not first strike Norway by 
the Trondhjem Fiord, but by the mouth of the Orkla River, 
thence into the valley of the River Nid, and so reached the 
Graakallen; and I might further remark, judging from the type 
of coast-land between Bergen and Trondhjem, that migrants 
from the Scottish coasts will likely seek the Norwegian coast to 
the north of Trondhjem, leaving the greater part of Norway to 
be occupied by birds migrating north by way of Heligoland and 
the entrance to the Baltic. Birds were comparatively tame, and 
were not molested by boys. I noted a kind of nervousness about 
them, but then they are seldom disturbed in their breeding 
haunts. 1 give a list of the birds observed on the Graakallen, 
omitting the Gulls, which flew across country from the harbour 
at Trondhjem to the mouth of the Orkla. 
MistLe-Turvuss (Turdus viscivorus).—I came upon a pair on 
the east slope of the hill, pretty low down, which seemed to have 
a nest, judgizz from their anxious behaviour. 
Sona-Turuse (7. musicus).—Distributed all over. Strange 
however, were it not for their song it was easier finding their
