in central and northern Illinois or 10 in both sections together, leaving 
9 species seen in southern Illinois and not farther north. Most of these, 
however, are usually to be found in central and northern Illinois in | 
winter, but no doubt in smaller numbers than in the southern part of 
the state. As usual, the southern Illinois bird fauna was not only more 
diversified than the northern, but the leading species were each repre- 
sented by a smaller number of birds. While three northern Illinois 
species were sufficient to make up 85 per cent of the whole number in 
that section and two central Illinois species were more than enough, 
eight were needed in southern [llinois—namely, the junco, quail, tree 
sparrow, song sparrow, blue jay, and cardinal and either the prairie 
horned lark, meadowlark, or bluebird.

Our data for yards and gardens in winter call for bare mention only. 
On five northern Illinois patches so classed, amounting to 534 acres, the 
only birds were two chickadees, and these were in a hedge beside a 
barnyard and not in the yard itself. In 5% acres of central Illinois and 
8%4of southern, English sparrows, in numbers averaging about a dozen — 
to the acre, were the only birds seen. A comparison of these numbers 
with those of the sparrow in other situations indicates that even in 
winter Passer domesticus is almost wholly a domestic species—3938 to
