in winter, and then visit the other parts of Sweden 
towards the south. The Falconers establish themselves 
always on the Dovrefeld, but they only take young 
birds of the year. In Holland, also, the Falconers 
take from time to time specimens of the young bird; 
from which we may conclude with Nillson, that the 
adults never go far from their habitual dwellings. 
Very little is known about the habits and propagation 
of this bird in its wild state. 
Mr. Wolley, Jun., writing in 1856, says im his 
“Catalogue of Eggs,” sold by Mr. Stevens:—‘ Falco 
Gyr-faleo of Schlegel is the true Gyr-Falcon at pres- 
ent so little generally known in England, though 
Schlegel says the young have occurred here, as they 
do constantly in Holland. In immature plumage the 
bird is scarcely to be distinguished from the immature 
Icelanders. Whether to be considered a distinct species 
or not, this Lapland, and, probably Siberian form, 
must be carefully separated from the Greenland and 
Iceland ones, which are so well known through the 
researches of Mr. Hancock. Schlegel, writing three or 
four years ago, says that nothing is known of its nidi- 
fication; these eggs are therefore probably the first 
that have been seen by naturalists. Mr. Wolley, in 
1854 and 1855, had the pleasure of taking four nests 
“with his own hands.” It breeds in the most remote 
districts, commencing whilst the winter snow is still 
undiminished. The adult birds seem to confine them- 
selves to the far north of the country, and they are 
the only species or race of the Great Falcon which 
occurs in Lapland.” 
Writing again in 1858, the same able naturalist 
further observes:—“‘In Scandinavia the forms found in 
Greenland and Iceland never seem to occur. ‘There
