Picus tridactylus or P. minor have made an entrance. ‘The nest has a foundation of green moss, 
and upon that a thick layer of wool, reindeer-hair, and especially Lemming-hair. The eggs, seven 
to nine in number, are glossy white, with reddish violet and reddish brown spots, often collected 
at the larger end, and are broad in proportion to their length. They resemble those of the 
Willow-Wren (Sylvia trochilus), but when fresh are not so red, and are more glossy. The spots 
on the eggs of S. trochilus are more numerous, more reddish brown, and distributed over the 
whole egg. When one has the nest the eggs cannot be mistaken. Mr. Wolley found eggs of 
Parus sibiricus and of the Redstart (Sylvia phenicurus) in the same nest.” Mr. Wheelwright 
also gives the following note in his ‘ Spring and Summer in Lapland’ :—“ The nest of the Siberian 
Titmouse was always placed in a stub, the nest built of the blue fur of some species of field- 
mouse; a very thick wall, but flat, and with a little moss at the bottom outside; the eggs, six or 
seven, in shape, size, and colour much resembling those of the Crested Tit. The Siberian Tit 
seems to go to nest later than the Parws borealis; for the first nest we obtained was on June the 
5th, whereas I found nests of the other as early as May the 20th.” 
Herr Magnus von Wright says that it occasionally occurs in Finland on its wanderings 
southward in the winter, but is a true inhabitant of Lapland. Those that have been observed 
there resemble the Great Titmouse in habits, and frequent the yards about inhabited places, 
picking up scraps. According to Nilsson it is found in the high north of Scandinavia during 
the summer, migrating southward as low as Upsala in the winter. In Lapland it is the 
commonest of the ‘Titmice; and Mr. Lowenhjelm found it from the boundary of Lycksele, 
Lapland, up to the fells, where it occurred into the birch-region. Professor Sundevall writes 
as follows :—‘ In Scandinavia it belongs properly to the conifer forests of Lapland and the sides 
of the fells, although it may sometimes in summer be found a little below these districts. It is 
common at Alten (70°), and is found in the same latitude in East Finmark, according to 
Nordvi, but not at Hammerfest, where the pine-woods cease. Its most southern range is on the 
Dovre (62°), and perhaps some of the southern fells, but only in the pine-forests above the spruce- 
growth. In Sweden it is found from 68° to 69° to the neighbourhood of Lycksele, 64° to 65°. 
But in the autumn and winter it migrates down to Vester Votten and Norrland, and occasionally, 
though rarely, reaches Upsala and Stockholm, as in the winters of 1838-39 and 1842-43. 
During the latter winter a small flock even wandered as far down as Bohuslan. The most 
eastern localities where it has been observed are Enare Lapland, and Kuopio in Finland, where 
it sometimes comes in the winter. It is unknown as to whether it has been seen on the White 
Sea or elsewhere in Russia and Western Siberia; but on the Jenesei Middendorff found, near the 
Polar Circle, a bird so closely resembling the Lapland one, that it must be looked on as the same 
species, although a variety that can be distinguished. Further eastward it seems that different 
though allied species occur. 
“The Lap-Titmouse affects pine-forests, and is more seldom found amongst alder and birch, 
and in its habits much resembles the Marsh-Titmice. Like them it is chiefly found amongst 
scattered large trees, or their young growth. Its general call-note is shorter than that of the 
Parus borealis, and consists partly of a harsh arrr or wrrr, and of a softer prré. It builds in 
hollow trees like the others.” Mr. Collett gives the following note in his ‘ Norges fugle’:—
