and is probably confined to very old individuals. Their appearance 

 is preceded by a streak of wax-red colour along the shaft of the 

 feathers, before the waxy appendages are developed. 



Adult female. Similar to the male, but with the crest smaller and 

 apparently not having so many waxy appendages to the secondaries, 

 and, as far as my experience goes, not having any on the tail. 

 Total length 7 inches, culmen 0-55, wing 4*4, tail 2-5, tarsus 0-75. 



Young males in Jirst ivinter pluma<je resemble the fully adult 

 bii'ds, but have the white cheek-spot much smaller, the secondaries 

 only minutely tipped with wax-drops, the first primaries white near 

 the end of the outer web instead of yellow; the tail-feathers not 

 tipped with wax-drops. 



Young females resemble the young male, but have the crest 

 smaller and the black on the throat not so distinct nor coming so 

 far down on the lower throat. 



Young. Diflers from the adidt. General colour above dark olive- 

 brown, streaked with pale edges of whity brown on the feathers of 

 the hind neck and back, less distinct on the rump ; head uniform 

 brown, with a line of velvety black running from the fore part of 

 the eye across the base of the forehead and surmounted by a narrow 

 whitish line, which extends also across the base of the forehead 

 above the eye ; ear-coverts and cheeks brown ; the fore part of the 

 latter white, forming a spot ; a narrow moustachial line of black ; 

 throat, breast, and flanks brown, streaked with pale fulvous edges 

 to the feathers ; centre of abdomen yellowish white, becoming 

 clearer yellow on the vent ; the under tail-coverts pale tawny buff ; 

 upper wing-coverts ashy grey, slightly washed with brown ; 

 primarj'-coverts and quills ashy grey ; the inner secondaries browner, 

 with white edges to the inner webs ; the primaries externally edged 

 with hoary white ; tail-feathers ashy grey, tipped with bright 

 yellow, before which is a subteiTuinal baud of black. 



Hah. Breeds within the Arctic circle in the jN^earctic and PaliE- 

 arctic Regions, migrating south in winter ; its immigrations very 

 irregular.
