The Upper Hall contains exhibition devoted entirely to the diversity of birds and mammals. Nearly all specimens shown in the displays are stuffed skins mastered by best Russian taxidermists who have been working in or for the Museum since the end of XIX century up the recent days. Most of the exhibits are individual specimens as such, and they are arranged systematically. But few of them are gathered in smaller or larger biogroups showing animals in their environments, such as the "Bird's Market". Besides, of interest is special display about hunting with the birds of prey. Section of birds and mammals each is forworded by an introductory display, and each order is supplied with textual characteristics.
