^Phylloscopus collybita tristis. The Siberian Chiffchaff. 

 The only specimen recorded was procured on 1(5 October, 

 1910. 



^Phylloscopus humei prsemium f- The Yellow-browed 

 Warbler, Given an easterly type of weather at its 

 migration period, sufficiently wide-spread to extend to its 

 Asiatic haunts, this little Warbler may be expected to visit 

 our shores in autumn. We have seen it on the May in the 

 autumns of 1907, 1908, 1909, & 1913, between 16 September 

 and 24 October, sometimes two or three on the same day. 

 Yellow-browed Warblers are very restless little birds, always 

 on the move, flitting from place to place at lightning speed. 

 They have a loud clear note — a ringing " pee," that may be 

 heard at a considerable distance. It would be interesting to 

 know whether the Yellow-browed Warblers that penetrate 

 to this country ever regain their regular wintering place. 



Turdus viscivorus viscivorus. The Missel-Thrush. Occurs 

 in small numbers on double passage. In spring, movement 

 is recorded in February, March, and April, with stragglers 

 into May ; the earlier of these probably refer to returns of 

 our own breeding-birds, the later to migrants going overseas. 

 Exceptionally early returns are noted in July and August, 

 but the period of normal autumn migration is the latter half 

 of September and October, and single birds were at the 

 lantern on 16 November, 1900, and 12 Noveml)er, 1913. 



*^Turdus musicus musicus. The Continental Song- 

 Thrush. An autumn passage migrant, and probably also 

 occurring in spring. We have specimens of this bird taken in 

 rushes at the end of September and in October, and no doubt 

 the large immigrations that take place in late October and 

 early November belong to the typical form. Large move- 

 ments of Thrushes take place in February and March; Con- 

 tinental birds are probably present in these, but of this there 

 is, as yet, no proof. On several occasions we have seen one 

 to three Thrushes in May, these were always very wild and 

 unapproachable, and the fugitive glimpses which we had of
