Note 230 — Chapter XVI

See, for instance, Mr. Gould’s account (‘Handbook of the Birds of Australia,’ vol. i. p. 133) of Cyanalcyon (one of the Kingfishers) in which, however, the young male, though resembling the adult female, is less brilliantly coloured. In some species of Dacelo the males have blue tails, and the females brown ones; and Mr. R. B. Sharpe informs me that the tail of the young male of D. Gaudichaudi is at first brown. Mr. Gould has described (ibid. vol. ii. p. 14, 20, 37) the sexes and the young of certain Black Cockatoos and of the King Lory, with which the same rule prevails. Also Jerdon (‘Birds of India,’ vol. i. p. 260) on the Palæornis rosa, in which the young are more like the female than the male. See Audubon (‘Ornith. Biograph.’ vol. ii. p. 475) on the two sexes and the young of Columba passerina.
