C. B. TICEHURST: PLUMAGES. 245 



Adult Summer-Plumage. Acquired by the same pro- 

 cesses as the First Summer-Plumage, and as a rule is 

 indistinguishable from it. 



BRITISH SONG-THRUSH. 



Turdus musicus clarkei, Hartert. 



MALE and FEMALE. 



Down - Plumage. Buffish- white. Distribution — Inner 

 supra-orbital, occipital, humeral, spinal and ulnar (c/. Vol. 

 II., p. 188). 



Juvenile Plumage. Acquired while in the nest, the 

 Down-Plumage being completely moulted. 



Whole head, hind-neck, mantle and scapulars clove-brown, each 

 feather with a darker tip and a mesial ochreous streak, small and faint 

 on the head and neck, larger and more distinct on the mantle and 

 largest on the scapulars (where in some it forms an elongated streak 

 or oval spot) ; rump rather paler and more ochreous ; upper tail-coverts 

 clove-brown washed with ochreous ; superciliary (ending in a post- 

 orbital streak) buffish-white or ochreous-buff ; ear-coverts and cheeks 

 golden-buff, the feathers faintly tipped with brown-black ; moustachial 

 stripes are formed by creamy-buff feathers with well marked brown- 

 black tips ; chin and throat dull white or huffish-white, tipped at the 

 sides and lower part with brown-black ; breast and flanks pale golden- 

 buff, each feather tipped with roundish brown-black spots ; belly dull 

 white sparsely splashed with pale golden-buff and with a variable 

 amount of small brown-black markings ; under tail-coverts very pale 

 golden-buff ; tail clove-brown ; primaries and secondaries dark brown 

 washed with golden-brown on the outer webs except towards the tips, 

 and the two innermost secondaries faintly tipped with pale ochreous, 

 inner margins of the underside of the remiges pale buff ; primary- 

 coverts golden-brown with conspicuous brown-black ends forming a 

 " wing-spot " ; greater coverts dark brown washed with golden-brown 

 on the outer webs and with golden-buff tips forming a wing-bar (the 

 inner four or five feathers usually having also mesial terminal streaks 

 of the same colour) ; median and lesser coverts golden-brown with a 

 mesial streak of golden-buff or ochreous ending in a broad tip to each 

 feather ; axillaries and under wing-coverts golden-buff. 



N.B. — The intensity of the golden-buff coloration, the size of the 

 ochreous markings, and the number of feathers in the great coverts 

 having mesial streaks, vary in different individuals. 



By the time the moult into the next plumage has started, the 

 ochreous and golden-buff colours of the superciliary, back, breast and 

 wing-coverts in many specimens become paler by wear and fading. 



First Winter- Plumage. Acquired by a complete moult, 

 with the exception of the rectrices, remiges, primary- and 

 a variable number of the greater wing-coverts (usually all 

 except the innermost three or four). 



Whole head, hind-neck, mantle and scapulars clove-brown ; rump
