Although situated about 20 miles north and the same distance 
east of Mt. Carmel, the bird-fauna was entirely the same, allow- 
ing for differences in the character of the country, the environs 
of Wheatland being much less varied, and therefore not such as 
to attract so great a variety of species. Nearly all the charac- 
teristic summer birds found further south were abundant near 
Wheatland, however, even Peuccea illinoensis occurring there. 
Among the more numerous species were the Cerulean, Blue- 
winged Yellow, Kentucky and Prothonotary Warblers, all of 
which were quite as numerous as near Mt. Carmel. At the time 
of my arrival, the most abundant bird was probably the Cardinal 
Grosbeak, it being no unusual sight to see several males at one 
time along the railroad track, picking up grain dropped from 
passing cars, while the swamp and surrounding woods were 
filled with their sweet but monotonous whistlings. Later in the 
season, however, other species became rather more numerous, it 
being difficult to decide between the Redstart and Red-eyed 
Vireo, as to first rank in point of numbers. Other species 
almost as well represented as those mentioned, were the Red- 
headed Woodpecker, Tufted Titmouse, Blue Jay, and Red-winged 
Blackbird, and, for a brief season, the Rose-breasted Grosbeak 
and Cedarbird. Hawks were very plentiful, especially the Red- 
shouldered and Red-tailed, and on one occasion eight of the 
former (all adults) were observed soaring about, near together, 
uttering their clamorous cries. Barred Owls were exceedingly 
numerous among the trees growing in the swamp, and at night 
afforded much amusement by their “family squabbles.” Ducks
