ern Illinois, in which more than half of our shrubbery area was found. 
The central Illinois data are comparatively worthless because two flocks 
of English sparrows and chickadees respectively contained 73 of the 80 
birds noted in the shrubbery of that section. English sparrows and 
quail numbered nearly half of all the birds of the state list in shrubbery, 
and the other more abundant species were chickadees, juncos, and blue 
jays, these five taken together making 82 per cent of all the shrubbery 
birds, leaving but 18 per cent for the other twelve species of the com- 
plete list. The special southern Illinois list—one made up, that is, of 
birds not seen in shrubbery farther north—comprises the quail, red- 
bellied woodpecker, purple finch, tree sparrow, junco, song sparrow, 
fox sparrow, tufted titmouse, Carolina chickadee, and bluebird—10 
species out of 17 for the whole state.

__.* The numbers starred make up 86 per cent of the total number of shrubbery 
birds in the state at large. 
On our 250 acres of waste and fallow lands, 395 birds, representing 
nineteen species, were found,—equivalent to 1012 to the square mile. 
Much the most numerous of these were the gregarious tree sparrows 
and juncos, the latter about two-thirds as abundant as the former, (224 
and 364 to the square mile respectively), the two together making 58 
per cent. of the whole number of birds. All but one of the nineteen 
species were represented in the southern Illinois list as against 7 and 8
