MISTLE-THRUSH. I93 



noticeable character, however, is a broad band of lemon-yellow 

 across the rump. Length, 37 ins. Wing, 2*1 ins. Tarsus, 

 '6 in. 



Dusky Warbler. Phylloscopus fuscatus (Blyth). 



A female Dusky Warbler, an eastern Siberian bird which 

 winters in south-eastern Asia, was taken in the Orkneys in 

 October, 19 13. It is unlikely that it often wanders so far from 

 its usual haunts. The upper parts are brown, the eye-stripe 

 buffish white, the ear-coverts and neck buff mottled with brown, 

 and the under parts white tinged with buff, darkest on the flanks. 

 The bill and irides are dark brown and the legs flesh-colour. 

 Length, 4 ins. Wing, 2*45 ins. Tarsus, '9 in. 



Family TURDID^. Thrushes. 

 Mistle-Thrush. T^irdus vlscivonis Linn. 



The Mistle-Thrush (Plate 80) is a common resident in the 

 British Isles, and throughout most of Europe and western 

 Siberia. It is partially migratory ; many of our birds leave in 

 late August or September, and Continental visitors arrive from 

 September onwards. Some of these remain as winter visitors, 

 and others are birds of passage to winter quarters in southern 

 Europe and northern Africa. The return northwards is notice- 

 able in Britain in February, and continues until April. 



The name, derived from its habit of feeding on mistletoe 

 berries, where these abound, is less descriptive than Stormcock, 

 which has several variants, for early in the year, when the 

 weather is broken, the bird perches high on a tall tree and in 

 exultant and ringing song deftes the elements ; I have heard it 

 singing during a driving snowstorm. In gardens, open fields, 

 woodlands and bleak hillsides this large, conspicuous greyish 

 thrush is equally at home. It stands with head well raised,
