1:34 BRITISH BIRDS. [vol. x. 



Family Bombycillid^. 

 Waxwing [Bomhycilla garrulus). 



Adults. — Complete luoult in October and November. 

 No moult in spring and no change by abrasion. Exceptionally 

 adult females are indistinguishable from adult males, but 

 usually the tail-feathers have paler and narrower yellow 

 tips and are without red tips to the shafts, the yellow borders 

 at the tips of the primaries are paler than in the male and 

 usiially confined to the outer webs, the red waxy tips to the 

 secondaries are smaller and frequently missing from some 

 of the feathers. 



Juvenile. — The upper-parts are browner than the adult, 

 the feathers of the crown are only slightly elongated, the 

 chin and throat are brown instead of black as in the adult 

 and the lower breast and belly are slightly striated with pale 

 buff, the tips of the tail-feathers are duller, and those of the 

 primaries have the yellow and brown on the outer webs only 

 and the waxy tips to the secondaries are small and freqvaently 

 absent on some feathers. 



First winter. — The juvenile body-feathers, lesser, median 

 and greater wing-coverts are moulted in early autumn, but not 

 the wing- or tail-feathers, so far as I can ascertain, but I have 

 been able to examine only one specimen in the moult from 

 juvenile to first winter. After this moult the birds resemble 

 the adults except for the differences in the wing- and tail- 

 feathers already referred to under the juvenile.
