Creepers, nuthatches, shrikes, and their allied forms, flycatchers and swallows, thrushes, dippers and babblers (about fifty species), bulbuls and orioles, peculiar types of redstart, various sylviads, wrens, tits, crows, jays and magpies, weaver-birds, avadavats, sparrows, crossbills and many finches, including the exquisitely coloured rosefinches, may also be mentioned.
There are deer (at least five species), boars, bears, antelopes, beavers, otters, badgers, tiger-cats, marten, an inferior sable, striped squirrels, &c. Among birds there are black eagles, peregrines (largely used in hawking), and, specially protected by law, turkey bustards, three varieties of pheasants, swans, geese, common and spectacled teal, mallards, mandarin ducks white and pink ibis, cranes, storks, egrets, herons, curlews, pigeons, doves, nightjars, common and blue magpies, rooks, crows, orioles, halcyon and blue kingfishers, jays, nut-hatches, redstarts, snipe, grey shrikes, hawks, kites, &c. But, pending further observations, it is not possible to say which of the smaller birds actually breed in Korea and which only make it a halting-place in their annual migrations.
All these birds are commonly called jays, and form a group of the crows or Corvidae, which may fairly be considered a sub-family, Garrulinae.
Indeed there are, or have been, systematists who would elevate the jays to the rank of a family Garrulidae - a proceeding which seems unnecessary.
In structure the jays are not readily differentiated from the pies; but in habit they are much more arboreal, delighting in thick coverts, seldom appearing in the open, and seeking their food on or under trees.
