In the trip across the central part of Illinois, made August 28 to 
October 29, 6382 birds were seen and counted, 31 of them not recognized 
and the remainder belonging to 102 species. Seventeen of the -more 
abundant kinds made up 85 per cent of the whole number, with an aver- 
age of 321 birds to the species, the remaining 85 species averaging but 
11 birds each. An enormous abundance of English sparrows, amounting 
to 38.6% of the whole number of birds seen and counted, reduces the 
number of native birds to 4278, 21 species of which, with an average of 
204 birds, were on the 85% list, the remaining 80 species averaging 
8 birds each. 
Among the more obvious evidences of migration shown by the 
following table of the more abundant central. Illinois species is the 
occurrence of considerable numbers of juncos, myrtle warblers, white- 
throated sparrows, and pipits, but the general composition of the list
