These numbers vary from 318 to 400 species in Lapland, from 508 to 651 in Karelia, and attain 752 species for Finland proper; while the total for all Finland attains 1132 species.
It breeds abundantly in some seasons on the fells of Lapland, its appearance depending chiefly on the presence of lemmings (Lemmus norvegicus), on which it mainly preys.
Nests of this species were found in 1821 by Johana Wilhelm Zetterstedt near Juckasj,rwi in Swedish Lapland, but little was known concerning its nidification until 1855, when John Wolley, after two years' ineffectual search, succeeded in obtaining near the Finnish village Muonioniska, on the Swedish frontier, well-authenticated specimens with the eggs, both of which are like exaggerated bullfinches'.
He travelled in Finland and Lapland in 1873-4, and in 1875 made a special study of archaeology and ethnology in the Balkan States.
They sailed in May 1553, but Willoughby and all his crew perished on the Lapland coast, Chancellor, however, was more fortunate.
