N. of the Perm Government. [In Asia its range extends right across the 

 northern part of the Continent to the Kolyma delta, Korea, Ussuria and 

 Kamtschatka.] 

 Nest. Apparently this bird does not arrive at its breeding haunts in 



Finmark and the Murman coast till the latter part of June, when-the 

 monotonous song of the cock may be heard all day among the birch 

 trees. The nest is placed on the ground on wooded slopes : it is domed 

 and loosely built of dry grasses and stalks with some moss, on a foun- 

 dation of dead birch leaves. The lining consists of fine grasses only, 

 without any hair or feathers. The cock sings at some distance from 

 the nest, and does not show any anxiety with regard to it. 

 Egga. Apparently 6 or 7 in completed clutches. Very few authentic eggs 



are available for comparison, but two sets in Messrs, Dresser's and 

 Bunyard's collections show a good deal of the white ground and are 

 sparingly marked with bold spots of dark red brown. The clutch taken 

 by Seebohm on the Yenesei is very different in character, being spotted 

 with faint reddish or pink, but the nest was similar to those found by 

 CoUett. 



Breeding CoUctt estimated the dates for the first eggs in the three nests 



found by him as July 9, 10 and 11 and probably the usual time is from 

 the last week in June to the second week of July. 



Measure- Average of 7 Lapland eggs, 16.38 X 12.7 mm.. Max. 17.1 X 12.7 



and 16.9x13, Min. 15.7x12.5. Seebohm's clutch of 5 eggs averages 

 16.26X12.5.

Breeding Range: Siberia, from the R. Ob to the Sea of Okhotsk, 

 and S. to lake Baikal. 

 Dis- This bird is of frequent occurrence in W. Europe on the autumn 



migration. Its breeding haunts are among the woods of the Siberian 

 valleys. Finsch has recorded it from the R. Ob; Seebohm, Popham and 

 others have found it very common on the Yenesei, and it is also known 

 to occur on the Lena, Kolyma, and many other rivers east to the R. 

 Anadyr. It is apparently absent from Kamtschatka, but is found in the 

 Stanovoi Mts., and is small numbers in Corea, as well as in Transbaikalia, 

 Kultuk, S. B. Mongoha etc.
