Guillemot (Lomvia bruennicht),and the Little Auk (Mergulus). 
All these species, whose breeding haunts lie further east or 
further north than the confines of Norway, visit our coast more 
or less commonly, chiefly in the winter, but a few of them also in 
summer. It is indeed a truly remarkable trait in these species 
belonging to the far north (especially the waders), which as breed- 
ing birds belong to the most northerly coast-lines of Europe, or 
even still more northerly regions, that many individuals often spend 
the summer on the most southerly coasts of Norway or still further 
to the south. All these consist of one- or two-year-old indi- 
viduals, who are waiting until they attain to breeding age. 
Thus, there ‘“‘summer” annually on the southern extremity of 
Norway (Listerland and Jederen) flocks or stray individuals 
of Tringa canutus and Tr. subarquata, of the Sanderling (Calidvis), 
and of the Grey Plover (Squatarola helvetica), and also of the 
Great Northern Diver (Colymbus glacialis), and others; whilst 
the tully adult individuals of these species are hatching out 
their young in the extreme north; also of Tvinga minuta, Tr. 
temmincki, of the rusty-red Bar-tailed Godwit (Limosa lapponica), 
and of the Spotted Redshank (Totanus fuscus), which each as 
breeding birds with us, belong only to Finmarken, while the 
young birds are to be met with in the south, all through the 
summer. It is as if the desire to revisit the regions in which 
they first saw the light, does not awake in earnest before they 
themselves breed. 
Inside of T island lie a multitude of large and small holms 
or islands, some low, others precipitous and mountainous, and as 
a rule only inhabited by a pair of miserable sheep which are 
lodged here in the short summer time. But on most of these 
desolate-looking holms it is worth while for the ornitho- 
logist to go ashore. If the ground is heather-covered and 
swampy, there will never be lacking some nesting pairs of 
different species of Tvinga ; and on the drier places, where the
