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 Beuccea 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 nimibers. 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
