THE BIRDS OF YORKSHIRE. 



MISTLE-THRUSH 

 Turdus viscivorus (Z.)- 



Common resident, generally distributed. An influx of arrivals from 

 the north occurs in autumn, some of which move further south, while 

 others winter. 



The earliest mention of this as a Yorkshire bird is con- 

 tained in the Appendix to the Rev. John Graves's " History 

 of Cleveland," dated 1808. 



Thomas Allis, in his " Report on the Birds of Yorkshire," 

 prepared for the York Meeting of the British Association, 

 in 1844, wrote of this species as follows : — 



Turdus viscivorus. — Missel Thrush — Common over the county. 



In addition to being a very generally distributed and 

 abundant resident, flocks of immigrant Mistle-Thrushes 

 arrive on our coasts in the autumn from Northern Europe, 

 where the bird is to some extent a summer visitant ; thus 

 at Redcar on 4th October 1884, at 8 a.m., flocks were 

 " coming in," the wind being X.W. and fresh (Sixth Migration 

 Report, p. 41) ; and on nth October 1885, there occurred 

 a great " rush " at Teesmouth (Seventh ]\Iigration Report,, 

 p. 38). They are less noticed at the Light Stations than 

 any other of the genus, being frequently confounded with 

 Fieldfares, and both species indifferently designated as " large 

 grey thrushes." Some of these immigrants no doubt remain 

 with us during the winter months, and may leave us for a 

 more southerly clime on the first really severe weather.
