Note 113 — THE GOLDEN ORIOLE. (Oriolus galbula.)
Reading edition
On this point the late Mr. Blyth, writing in the Natural History columns of “The Field,” 17th August, 1872, under the signature “Z.,” remarked that Orioles are amongst the few birds which breed before attaining the mature plumage, and the females acquire this later than the males, being always, however, of a greener shade. He had observed this in O. melanocephalus, O. chinensis, O. tenuirostris, and O. acrorhynchus, but thought that “the old females of O. galbula, and O. kundoo, less frequently attain the male colouring than those of the other species mentioned.”
