 hair-brown, with white shafts. Tail doubly forked, the

Fig. 4. Is the young of this species ; in which state it Young 

 very closely resembles the immature bird of the prece- 

 ding one. The eye-streak is, however, more distinct, 

 and the breast more inclined to pale yellowish-brown. 

 The dark zone which encircles each feather in the upper 

 parts of the body is also more defined and intense in co- 

 lour, giving a spotted appearance. The comparative 

 length of the tarsus, as in the adult, is of itself sufficient 

 to distinguish it from T. Temminckn.
