Similar, the hood being perfectly black in the spring and summer preceding the mature plumage above dcscrilied, and the only difference being in the pattern of the quills. All of these are white to palest grey on the greater part of their inner webs, and entirely so in the two outer pairs, but both of the latter quills have some black on the outer webs, while on the 3rd and 4th the black crosses both webs subterminally. In the previous year (as I believe) the head is also black; the portion of the inner webs next the shafts is also black in the three outer quills, the black spreading out into a transverse bar, except on the 1st, where the white breaks through; the 4th and 5th are also barred, and all have broad white tips. This dark colour appears to fade gradually out of the feather—earliest on the inner webs— (as it docs in other species), to judge from a specimen obtained at.
