In tho adult male in hreeding-plumaye the general colour is dark 

 slate-grey suftused with metallic cobalt-blue, most so on the head 

 and least so on the under taU-covcrts ; lores dark slate-grev • 

 wings, wing-coverts, and taU dark brown, the outer web of each 

 fea her margined with blue; under tail-coverts with white tips 

 and obscure subt^rminal dark bars. BiU black. Wing with the 

 third and fourth primaries nearly equal and longest, second

 tail 6-6 to 3-1, culmen 1-1 to 0-9, tarsus 1-15 to l-Q 



After the autumn mouU most of the feathers have narrow 

 greyish-white margins, those of the upper parts with obscure brown 

 subtermma bars, and those of the uuderparts with darker brown 

 subtermmal bars, almost obsolete on the chin and throat These 

 marginal and subterminal bars are cast during llarch leavin- the 

 male in full breeding-pUnnage. The female somewhat resembles 

 the autumn plumage o the male, but is much more brown, being 

 far less sutiused with blue. The whole of the underparts .re pale 

 wh tisb orown, slightly sutiused with blue on the breast and belly 

 each feather having a dark-brown subterminal transverse band 

 which on the throat is continued on the margins of the feathers • the' 

 axiUanes and under wing-coverts have several transverse dark bars 

 Birds of the year and youay in first plumage differ from the female 

 very slightly.
