Con- Ijj European Russia the range of this bird extends from the Pet- 



Europe, schora valley eastward, while southward it is found as far south as Perm 

 (Meves) and the Middle and Southern Urals. [In Asia it is found 

 throughout Siberia as far E. as Transbaikalia, in the Altai range, and 

 as far S. as the Karakorum Mts., Ladakh (J. Bomb. N. H. S. XVII, 

 p. 112), and Gilgit (Ibis, 1881, p. 65).] 

 ^^^*- Seebohm and Popham describe nests from the Yenesei valley as 



being hollows in the wisps of flood wrack left stranded in the willow 

 bushes after the submergence of the floods, and warmly lined with 

 feathers of the "Willow Grouse and Capercaillie. Some nests were 

 however found close to the ground in willow and alder thickets or 

 among rank vegetation. They varied in height from 4 ft. to only a few 

 inches above the ground. 

 Eggs. jjj ;^ Siberia 4 to 5 is the usual number but sets of 6 and 7 have 



been sent from the Altai. They much resemble those of P. collybita 

 collybita, being finely spotted with dark red, chiefly at the big end. 

 Breeding It appears to be a late breeder on the Yenesei, the eggs being 



Season, j^^^ about the end of June or early in July, but eggs from the Altai 



range are dated May and June. 

 Measure- Avcragc of 64 eggs measured by the writer, 14.97 X 11.9 mm., 



""''*'■ Max 19 X 11.2 and 15.5 X 12.6 Min., 14 x 11.4 and 19 X 11.2. Rey

[In the Canaries are found two more forms of Chiifchaff: P. colly- 

 bita canariensis Hartw. on the Western islands of the group, Tenerife, 

 Gran Canaria , Palma and Hierro : and P. collybita exsul Hart, on 

 Lanzarote. P. e. canariensis lays only 3 to 4 eggs as a rule, occasionally 5, 

 which are either white or sparsely marked with fine brown spots. They 

 are laid in March and April, and 48 average in size (30 by Koenig and 

 18 by the writer), 15.52x12.05 mm.. Max. 17x12.5, Min. 13.5x12
