BIRDS OF THE HUMBER DISTRICT. 15 



24. SYRNIUM STRIDULUM (Linnaeus). Tawny Owl. 

 Provincial. Hooting-Owl. 



Still not uncommon in the best timbered parts of 

 the county. 



25. SURNIA NYCTEA (Linnaeus). Snowy Owl. 



There is no recent occurrence of this fine arctic 

 species in this district. One was captured on board 

 a Danish vessel in the North Sea, off the coast 

 of Scotland, in December 1867 (Zoologist, 1868, 

 p. 1058). During the glacial period, this, like other 

 northern species, probably ranged far south of its 

 present haunts, and has since gradually retired with 

 the Lap and his reindeer*. 



26. NOCTUA TENGMALMI (Gmelin). Tengmalm's Owl. 



On the 1st of October, 1863, after a heavy gale 

 from the north-east, a splendid female of this rare 

 little Owl was taken in the daytime, in a field at 

 Flamborough, by Robert Barkley, of that place. 

 Ultimately it came into the possession of Mr. 

 Boulton, who has recorded the circumstances of its 

 capture in the ' Zoologist ' for 1864, p. 9020. 



27. STRIX ACADICA, Gmelin. Saw-whet Owl. 

 In the < Zoologist' for 1860, p. 7104, Sir William 



* The bones of the Snowy Owl (Surma nycted) have recently 

 been discovered in Quaternary deposits in France.
