[271] I am indebted to Mr. Blyth for information in regard to the Buphus; see also Jerdon, ‘Birds of India,’ vol. iii. p. 749. On the Anastomus, see Blyth, in ‘Ibis,’ 1867, p. 173.
[272] On the Alca, see Macgillivray, ‘Hist. Brit. Birds,’ vol. v. p. 347. On the Fringilla leucophrys, Audubon, ibid. vol. ii. p. 89. I shall have hereafter to refer to the young of certain herons and egrets being white.

[277] 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.
