26. PORZAXA. 



10a 



brown with a few white spots and bars ; (juills dusky below : " bill 

 green, darker at the tip ; legs, feet, and claws olive ; iris crimson " 

 (//. iSeehohm). Total length 7 inches, culmen 0-75, wing 3-5, tail 

 IT'y, tarsus I'Oo, middle toe and claw 1'5. 



The adult male in winter plumage appears to have a whiter 

 throat than in summer, and in all probability the entire throat 

 gradually becomes slaty f.'roy as the breeding-season approaches : 

 " bill grass-green, the culmen dusky ; tarsi and toes greenish ; iris 

 reddisli orange " {T. Ai/res). 



YoatKj. Is like the adult on the upper surface and is similarly 

 marked with black and white, but the general tone of the plumage 

 is rather more rufous ; the head like the back ; sides of the face 

 inifous brown, as also the eyebrow ; lores whitish ; throat, breast, 

 and abdomen dull white ; the fore neck and chest rufescent, barred 

 across with dusk)- ; lower Hanks, vent, and under tail-coverts black, 

 barred with white : "iris light ashy brown" {T. Ai/res). 



The young birds probably do not attain their full grey plum.'ige 

 for at least a year, as a specimen procured near Potchefstroom on 

 the 24th of April is still in immature plumage like the young bird 

 above described, and differs only in the whiter under surface, the 

 fore neck and chest alone retaining some remains of rufous shading 

 and dusky bars. The eyebrow is whitish and more distinct. If 

 this bird was going to moult into the grey plumage before its 

 returm to Europe, the change must be very rapidly performed.
