THRUSHES 39 



commonly building in a tree at some height from 

 the ground, this bird in the neighbourhood of the 

 Fells occasionally nests in the tops of dry stone 

 walls (Mitchell, "Birds of Lancashire," 2nd edit., 

 1892, p. 2). 



As to the proper mode of spelling the English 

 name of this bird, see the note by Prof. Newton in 

 Yarrell's "British Birds," 4th edit., vol. i. p. 260.

 fig. 6. Length, 9 in. ; wing, 4-5 in. ; tarsus, 1-2 in.

In dry summers Thrushes' nests are sometimes 

 found without the usual mud lining {ZooL, 1887, 

 p. 268; 1889, p. 312; 1893, p. 225), and are not 

 unfrequently built on the ground (Zool, 1887, 

 p. 112; Field, April 22 and 29; May 6, 13, and 

 20, 1899). It has been stated that Thrush and 

 Blackbird occasionally interbreed (Loudon's Mag. 

 Nat. Hist., 1834; Macgillivray, "Hist. Brit. Birds," 

 art. "Thrush;" Zool, 1883, p. 123; 1884, p. 146; 

 and Christy, Trans. Norf. Nat. Soc, iii. p. 588).
