THE WHITE-TAILED ROBIN FLY-CATCHER.
Length, 5 ; wings, 2.6 ; tail, 2 ; tarsus, 0.7.
Bill dusky-brown ; irides dark-brown ; legs pale-brown.
Above greyish olive-brown; wings brown ; tail blackish-brown ; the four outer tail-feathers on each side white for the greater part of their Length, broadly tipped with brown ; beneath white, tinged with ashy-brown on the breast and flanks.
In spring, by the end of March or the beginning of April, the male by a partial moult assumes a bright orange-rufous chin and throat, and the lores, cheeks, and sides of the neck become tolerably pure ashy. This livery is again cast at the autumnal moult.
The occurrence of the White-tailed Robin Fly-catcher within our limits is very doubtful.
