BLUE-THROATED WARBLER. 
103 
I he nest is composed, on the outside, of dead grass 
and a little moss, and lined with finer grass. The eggs 
are from four to six in number,” and usually resemble the 
one figured ; one, which Mr. Alfred Newton has sent me 
from his collection, is of a uniform olive-brown, as dark 
as the egg of the nightingale, from which it differs only in 
size. 
Acerbi mentions his having found several nests and 
eggs of this bird on the banks of the river Jeres, at the 
head of the Gulf of Bothnia. It is also an inhabitant of 
some parts of Norway. In that portion of the country 
which we visited it is rare, and only once afforded us an 
opportunity of seeing it, and then under circumstances 
which I can never think of without feelings of extreme 
pleasure. We were descending the steep and woody 
sides of one of the numerous islands with which the 
Norwegian coast is so thickly studded. It was after 
midnight, and the sun, which we had just seen set in 
glory above the horizon, was now with its rising beams 
diffusing an additional warmth over the face of nature, 
and adding a lustre to every beautiful and magnificent 
object around us ; Nature, which during the short deli¬ 
cious summer of these regions, seems scarcely to allow 
time for slumber or repose, v r as thus early in activity. 
The bees came humming past us, and a Blue-throated 
Warbler, which was in motion amongst the low brush¬ 
wood, arrested our progress. 
Although classed with the redstarts, in the little we 
saw of its habits, this species seemed much more to 
resemble the birds of the genus Curruca or Sylvia, in 
its hiding skulking manner.
