Rantoul, 111. — On a 400-acre tract near Rantoul, 111., counts were 

 made in four years, from 1916 to 1920. There are two small orchards, 

 together amounting to about 5 acres, with a garden near the house 

 and hedges and large trees about the buildings. Of the remainder 

 of the tract, about 300 acres were planted each year in corn and oats 

 and 50 acres were in permanent pasture and meadow. The birds 

 found breeding here have varied from 231 pairs of 35 species, to 340 

 pairs of 48 species, averaging 293 pairs and 42 species on the 400 acres, 

 or 73 pairs per 100 acres.
