tores, Scansores, Oscines, Columbæ, and Gallinaceæ; of the Grallatores and Natatores only one species breeds here. The proportions of the representatives in each class are, however, very unequal, the warblers (Oscines) being far the most numerous; next in order come the Raptores, then Gallinaceæ, then climbers (Scansores), and Columbæ last of all.
The following table will at once show the distribution of the birds of Kan-su:—
|Settled and nesting||Migratory||Total|
|1. Birds of prey (Raptores)||12||2||14|
|2. Climbers (Scansores)||7||0||7|
|3. Warblers (Oscines)||74||5||79|
|4. Pigeons (Columbæ)||3||0||3|
|5. Gallinaceous (Gallinaceæ)||9||0||9|
|6. Waders (Grallatores)||1||7||8|
|7. Webfooted (Natatores)||0||4||4|
On comparing the birds of Kan-su with those of Mongolia, we find as striking a difference between them as between their floræ—a fact accounted for by the contrast between the physical conditions of the two countries. Forty-three of these birds were foreign to Mongolia, and even more if we were to include the birds of the Munni-ula and Ala-shan ranges. The ornithology of Kan-su comprises Siberian, Chinese, Himalayan, and Thian-Shan birds.
Beginning with the Raptores, we first notice three kinds of vultures, the Snow-Vulture (Gyps nivicola), the Black Vulture (Vultur monachus), and the lam-
