The study area includes Mordovia, Penza region, right-bank parts of Ulyanovsk
and Samara regions, north part of Saratov region (Figure). Reliable literature
data about the ornithofauna of this area are known since the beginning of XIXth
cent. Short history of research is described. Data obtained on borders of XIXXXth
and XXXXIth cent. allow to compare the state of fauna of non-passerine birds
for the century. At the beginning of XXth cent. it counted 161 species from 17
orders, at the end 178 species from 16 orders (Table 1). Total during the
century 187 species from 17 orders were discovered (Table 2). At the end of XXth
cent. 9 species were absent: 8 vagrant ones and 1 sedentary species. 26 species
were found: 15 vagrant, 7 migrating and breeding, 3 passage
migrants, 1 sedentary. Sedentary non-passerine birds are represented by
23 species from 5 orders (Table 3). Willow Grouse is absent now, three new species
appeared: Tengmalms Owl, Grey-headed Woodpecker, Middle Spotted Woodpecker.
The group of migrating and breeding non-passerine birds has 94 species from 14
orders (Table 4). Wood Sandpiper was not found, 16 new species appeared. Passage
migrants are presented by 31 species from 6 orders (Table 5). It has 9 new species.
Wintering birds have 2 species from 2 orders (Table 6). Vagrant birds number 29
species from 7 orders (Table 7). Changes in numbers are presented in the Tables
812. The analysis shows the high degree of adaptation and the stability
to changes of non-passerines, which were considered as more vulnerable than passerines.
Key words: fauna, non-passerines, the Volga, number, changes, adaptation.
