[203] Daines Barrington, however, thought it probable ("Phil.
Transact." 1773, p. 164) that few female birds sing, because the talent would have been dangerous to them during incubation.
He adds, that a similar view may possibly account for the inferiority of the female to the male in plumage.

[209] For instance, the female _Eupetomena macroura_ has the head and tail dark blue with reddish loins; the female _Lamp.o.r.nis porphyrurus_ is blackish-green on the upper surface, with the lores and sides of the throat crimson; the female _Eulampis jugularis_ has the top of the head and back green, but the loins and the tail are crimson. Many other instances of highly conspicuous females could be given. See Mr. Gould"s magnificent work on this family.
[210] Mr. Salvin noticed in Guatemala ("Ibis," 1864, p. 375) that humming-birds were much more unwilling to leave their nests during very hot weather, when the sun was shining brightly, than during cool, cloudy, or rainy weather.
[211] I may specify, as instances of obscurely-coloured birds building concealed nests, the species belonging to eight Australian genera, described in Gould"s "Handbook of the Birds of Australia," vol. i. p. 340, 362, 365, 383, 387, 389, 391, 414.

[214] I have consulted, on this subject, Macgillivray"s "British Birds," and though doubts may be entertained in some cases in regard to the degree of concealment of the nest, and of the degree of conspicuousness of the female, yet the following birds, which all lay their eggs in holes or in domed nests, can hardly be considered, according to the above standard, as conspicuous: Pa.s.ser, 2 species; Sturnus, of which the female is considerably less brilliant than the male; Cinclus; Motacilla boarula (?); Erithacus (?); Fruticola, 2 sp.; Saxicola; Ruticilla, 2 sp.; Sylvia, 3 sp.; Parus, 3 sp.; Mecistura; Anorthura; Certhia; Sitta; Yunx; Muscicapa, 2 sp.; Hirundo, 3 sp.; and Cypselus. The females of the following 12 birds may be considered as conspicuous according to the same standard, viz., Pastor, Motacilla alba, Parus major and P.
caeruleus, Upupa, Picus, 4 sp., Coracias, Alcedo, and Merops.

[227] Mr. Blyth has recorded (Translation of Cuvier"s "Regne Animal," p. 158) various instances with Lanius, Ruticilla, Linaria, and Anas. Audubon has also recorded a similar case ("Ornith. Biog." vol. v. p. 519) with _Tyranga aestiva_.

[230] See, for instance, Mr. Gould"s account ("Handbook of the Birds of Australia," vol. i. p. 133) of Cya.n.a.lcyon (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 s.e.xes and the young of certain Black c.o.c.katoos and of the King Lory, with which the same rule prevails. Also Jerdon ("Birds of India," vol. i. p. 260) on the _Palaeornis rosa_, in which the young are more like the female than the male. See Audubon ("Ornith. Biograph." vol. ii. p. 475) on the two s.e.xes and the young of _Columba pa.s.serina_.
