title: [Venous sinuses of the dura mater of the bird brain].
abstract: By means of corrosive, injection and tracheoscopy methods venous formations of the brain have been studied in 19 species of birds--endemical for Far East--from 12 orders. Four types of the venous sinuses structure have been distinguished in the dura mater: the first type of the structure is specific for birds that live an inactive and quiet life (blue rock pigeon, Ussuric pheasant, Tetrastes bonasia, domestic hen). The second type of the sinus structure occurs in birds, that sharply change the speed and height of their flight (Otus bakkamoena). The most manifested changes in the sinus structure are noted in waterfowl and diving birds, that spend much time in flight, in dendrocolaptidae and in day predaceous birds; in them the longitudinal sinus forms a rhombus.
