Sitta minor. Male with the gular pouch extended (from ‘Gunther’s Reptiles of India’)


{In my native place we had this species, with red pouch under its neck, which was turning red. It remained immobile when someone approaches it. And the boys used to say, it is absorbing blood from our eyes, and we used to pelt stones at it. Fortunately we were bad at aiming!!}

The sexes often differ greatly in various external characters. The male of the above-mentioned Anolis is furnished with a cret which runs along the back and tail, and can be erected at pleasure; but of this crest the female does not exhibit a trace. In the Indian ‘Cophotis ceylanica,’ the female has a dorsal crest, though much less developed than in the male; and so it is; as Dr. Gunther informs me, with the females of many Iguanas, Chameleons, and other lizards. In some species, however, the crest in both sexes, as in the ‘Iguana tuberculata’. In genus Sitana, the males alone are furnished with a large throat-pouch (figure 33), which can be folded up like a fan, and bis coloured blue, black, and red; but these splendid colors are exhibited only during the pairing-season. . . . .

A Chinese species is said to live in pairs during the spring; “and if one is caught, the other falls from the tree to the ground, and allows itself to be captured with impunity,” – I presume from despair. ~ Page 367


. . . . We have seen that the males alone of Sitana possess a throat-pouch; and this is splendidly tinted with blue, black and red.. . . Page 369
