District 15—no one; District 16—Paul Biggers, Mike Biggers, Deborah Frey, 
Mary Hardenbergh; District 17—no one; District 18—Vernon Kleen, Tim 
Merriman. Appreciation is also extended to Richard Burdick for assembling 
the tables and Dorothy Bass for typing the tables and manuscript. 
FIGURE 1 shows the counties in 
min sla 
each District; TABLE 1 depicts the 
earliest arrival date and TABLE 2 
reflects the latest departure date for 
selected migrants throughout the 
state. (The total compilation for all 
species is available on request.) A 
zero (0) in the Tables indicates that 
the species was not reported dur- 
ing the period; a plus (++) or dash 
(—), the species was reported, but 
probably not the earliest arrival or 
latest departure: an “S,” arriving 
migrants could not be differentiat- 
ed from summering individuals; a 
“W,” departing migrants could not 
be safely differentiated from win- 
tering individuals.

LOONS and GREBES. Common Loons were reported quite commonly 
in northern and central Illinois; a noticeable increase in numbers occurred 
at Springfield, 16 Oct. and reached a peak of 65 there on 4 Nov. (D. Bohlen). 
The first state record of an Arctic Loon was a bird in near-adult plumage 
at Springfield, 3 Nov. (*D. Bohlen, *R. Sandburg, R. Palmer, m.ob.); an- 
other individual, recognizably different from the first, was found at Decatur, 
3 Dec. (*R. Sandburg). The always rare Red-throated Loon was reported 
from Illinois Beach State Park, 18 Nov. (*G. Rosenband) and Evanston, 
24 Nov. (*L. Balch). Individual Red-necked Grebes were observed at Evans- 
ton, 22 Sept. (*L. Balch, R. Russell); another at Springfield, 19-26 Dec. was 
photographed (*D. Bohlen, m.ob). Influxes of Horned Grebes paralleled 
those of the loons; unusual were migrating “flocks” of 15, 20, and 5 at Chi- 
cago, 13 Oct. (L. Balch, et al.); first arrivals were noted at Decatur the same 
day (R. Palmer); maximum highs inland were 39 at Springfield, 17 Nov. (D. 
Bohlen), 21 at Decatur, 27 Oct. (R. Palmer) and 5 in Vermilion County, 
17 Nov. (M. Campbell). At least six different Eared Grebes were present at 
Decatur during the period (R. Sandburg); only one at Springfield, 24 Oct. 
(D. Bohlen). High numbers of Pied-billed Grebes were reported several 
places this fall. 
PELICANS, CORMORANTS and HERONS. The first White Pelican was 
noted 12 Oct. at Lake Chautauqua, and was joined by another 27 Oct.; both 
remained there until 11 Nov. (m.ob); singles were reported from Swan Lake
