Darwin cited this in Descent 2: 220, n49: "The following additional cases may be mentioned: the young males of Tanagra rubra can be distinguished from the young females (Audubon, 'Ornith. Biography,' vol. iv. p. 392), and so it is with the nestlings of a blue nuthatch, Dendrophila frontalis of India (Jerdon, 'Birds of India,' vol. i. p. 389). Mr. Blyth also informs me that the sexes of the stonechat, Saxicola rubicola, are distinguishable at a very early age."
