i68. Turdus philomelus hebridensis Clarke. — THE HEBRI- 

 DEAN SONG-THRUSH. 



Turdus musicus hebridensis Clarke, Scott. Nat., p. 53 (1913 — Barra 

 Outer Hebrides). 



Description (Plate 14). — Adult male and female. — Upper-parts 

 darker, more earth-brown and less warm brown than in T. ph. 

 clarkei, and rump and upper tail-coverts more tinged with grey, 

 upper-parts thus more like T. j^h- philomelus in tone but consider- 

 ably darker and without olive tinge ; imder-parts much more 

 thickly spotted than in T. ph. clarkei or T. p)h. philomelus, spots 

 being larger and more intense black ; less buff on under-parts than 

 in T. ph. clarkei ; flanks considerably darker and more smoky-brown 

 than in either of the other races ; under wing-coverts and axillaries 

 darker and richer and more cinnamon-buff ; tail, wings and 

 wing-coverts darker than in either of the other races. 



Nestling. — (Not examined.) 



Juvenile. — Like that of T. ph. clarkei but upper-parts darker 

 and pale mesial streaks consequently more accentuated ; under- 

 ]oarts with less buff than in T. ph. clarkei, spots scarcely larger but 

 blacker ; flanks darker (more dingy) ; under wing-coverts darker 

 and richer as in adults. 



Measurements and structure. — As in, T. ph. clarkei, but bill 

 rather larger on average, viz. 22-24 mm. (12 measured). 



Soft parts. — Apparently as in T. ph. clarkei but possibly legs 

 and feet rather darker. 



Breeding-habits. — Owing to absence of trees nest is generally 

 built among rocks and heather, like that of Ring-Ouzel. Nest. — 

 Similar in construction to that of British Song-Thrush. Eggs. — 

 Also similar. 



Food. — ^In addition to worms, snails and insects, much of the food 

 of this race is obtained on the shore, marine mollusca, up to size 

 of A\'lielk. being largely taken. 



Distribution. — British Isles. — Apparently confined to 0. Hebrides, 

 but may possibly be found to inhabit some I. Hebrides also. 

 Has not yet been identified as migrant.
