Owing to the residence of Mr. Swinhoe in the island of Formosa for a considerable time, the ornithology of that island has been very thoroughly explored; and though it is quite possible that in the highest mountains of the interior some novelties still remain undescribed, we possess a more accurate knowledge of the birds of this island than of any other in the east, except perhaps Ceylon. The climate and physical geography, as described by Mr. Swinhoe, seem to resemble those of the E. Himalayas considerably; and it is no doubt partly owing to the heavy rainfall and forest-clad mountains that the zoological resemblance is so striking. An examination of the list of birds which was given by Mr. Swinhoe in the 'Ibis' for 1863, and increased by his later additions in the List of Chinese Birds (P. Z. S. 1871, p. 337), shows that, with the exception of four genera, three of which are peculiar to China and one peculiar to the island, every genus found in Formosa is also found in the E. Himalayas. Many genera which are not found in the Malayan subregion, as Herpornis, Sibia, Suthora, Urocissa, Suya, Spizixos, appear in the mountains of Formosa, as well as others, such as Pomatorhinus, Garrulax, Alcippe, Myiocincla, Myiophonus, which are much more characteristic of the Ilimalayan than of the Malayan subregion. The number of peculiar species is considerable, and shows that Formosa has probably been separated from the mainland for a long period. I have annexed a list of these species, gathered from Mr. Swinhoe's papers, with the nearest allies of many of them, in order to show the close affinity which Formosa has to Sikim. An examination of the list of Formosan birds shows 144 species belonging to 102 genera:- Genera found in the Ilimalayan subregion 98 Genera found in the Malayan subregion 70 |
