To Alfred Newton 19 January [1867]
Summary
Seeks explanation of the case of the Rhynchaea, of which the female is more beautiful than the male, with the young resembling the latter. Wallace has told CD that at Nottingham AN explained this by the male being the incubator.
Does the male black Australian swan, or the black and white S. American swan, differ from the female in colour of plumage?

Thanks for the information about the male plumage. [See 5374.] Will look to the papers in Ibis to which AN has referred him. He finds AN’s theory captivating.

To Alfred Newton 4 March [1867]
Summary
Thanks for information about the dotterel.
CD had ascertained by dissection that the female of the carrion-hawk of the Falkland Islands is very much brighter coloured than the male. Has inquired about its nidification. Mentions other instances of female birds that are brighter and more beautiful than the males and suggests causes for this anomaly.

From Alfred Newton 21 January 1867
Summary
Suggests that, in some birds, plumage of males is less colourful than that of females; the reason is that the males perform the duties of incubation [see Descent 2: 204 n.].
