Adult (Swaffham, fide Prof. Newton). "The whole of the beak black; from the crown of the head to the 

 nape of the neck the feathers are white at the base, broadly tipped with dark brown, so as to present, 

 except at the edges of the patch, which is nearly circular, a uniform surface of the latter colour; in 

 front and below the eye are a few greyish-black feathers extending over the ear-coverts ; the orbits are 

 surrounded with a ring of sepia-brown feathers. The forehead, face, neck, breast, belly, sides, and 

 under tail-coverts are nearly pure white ; but there are also a few dark feathers on the flanks. The 

 beak and shoulders are covered with greenish-grey and blackish-brown feathers, the former appearing 

 to have been but lately assumed ; but many of the latter are sedgy and worn at the edges : all these 

 feathers are white at the base ; but that colour does not show on the surface. The rump and upper 

 tail-coverts are white, the feathers of the latter elongated. The tail is rounded, and consists of twelve 

 feathers, the outer pair white edged and broadly tipped with blackish brown ; the next four pair are 

 similarly coloured, but only slightly edged, the tips of each pair being darker as they approach the 

 middle; the shafts of the quills in all these are white; the middle pair of quills are brownish black 

 nearly all their length, their basal being white, and have their shafts corresponding in colour to their 

 webs. The wing-coverts are blackish brown, bordered with a lighter shade of that colour, the borders 

 of the middle and lower coverts being so broad as to appear like two light-coloured bars across the
