BOHEMIAN WAXWING. 393 
chestnut ; the feathers on the top of the head a light brocoli- 
brown, and elongated, forming a crest; over the base of 
the upper mandible, on the lore, round the eye, and passing 
backward round the occiput under the back part of the 
crest, an elongated circle of black ; nape of the neck light 
brocoli-brown, becoming darker on the back, scapulars, and 
small wing-coverts; the coverts of the primaries black, 
_ tipped with white; primaries and secondaries black, with 
an elongated patch of straw yellow at the end of the outer 
web of all except the three first ; the tertials purple brown, 
tipped with pure white on the outer web; four of the 
secondary quill-feathers, and from one to four of the tertials, 
depending on the sex and age of the bird, terminate in a 
small, flat, oblong appendage, resembling in colour and 
substance red sealing wax; these appendages are merely 
expanded and coloured horny prolongations of the shafts of 
the feathers beyond their webs ; upper tail-coverts smoke- 
grey; tail-feathers smoke-grey at the base, black towards 
the end, and tipped with king’s-yellow, the shafts of the 
feathers being slightly tinged with red where the webs are 
yellow. Under the chin is a patch of velvet black; at the 
angle of the mouth the feathers are chestnut, passing on the 
cheeks, neck, breast, and all the under parts, into pale 
brocoli-brown, becoming greyish brown on the flanks and 
abdomen ; under tail-coverts chestnut brown; axillary 
plume, and under surface of the wings, ash-grey; all the 
plumage silky and soft to the touch; the legs, toes, and 
claws, black. 
The whole length of the bird rather more than eight 
inches. From the carpal joint to the end of the wing 
four inches and a half: the first and second feathers very 
nearly equal in length, and the longest in the wing, indi- 
cating considerable powers of flight.
