18 ILVINOIS AUDUBON BULL 
throat. The back was grayish-black with narrow whitish feather edgings 
in rows. This last character makes the bird a fall or winter juvenal (Palmer, 
1982). The bird swam lower in the water than the other loons, at 
times looking grebe-like. The head was held more straight, the bill not held 
up. The Arctic Loon did not flap its wings while sitting on the water and 
dove more often than the Common Loons. 
Later that day, Vernon Kleen, Patrick Ward, and Tom Crabtree saw 
the bird. The next day, birders from Chicago and I tried to find the Loon 
but could not re-locate it, although there were at least 60 Common Loons 
present on the lake. 
The Arctic Loon has been collected in Missouri and Iowa and probably 
is a regular migrant in very small numbers in Illinois. Winter-plumaged 
loons are notoriously difficult to identify, and I believe that the observer 
must have a close, long look, preferably in comparison with Common Loons, 
to identify the Arctic Loon. We were as close as 100 feet and spent from 
0900-1600 (although not continuously) studying this particular bird.

MEMORIAL FUNDS OF ILLINOIS AUDUBON 
A suitable memorial for a relative or a dear friend could be a donation 
to one of Illinois Audubon Society’s permanent funds: 
SANCTUARY FUND — This fund is the best assurance that we can 
fulfill our aim of preserving natural habitat for all native flora and 
fauna. This can also be aided by property gifts of parcels of land. 
BOOK FUND — The book fund is used to finance the publications of 
fairly extensive manuscripts. The current book being produced deals 
with where to find birds in Illinois. 
EDUCATION FUND — This fund is used to further the many facets 
of the society's educational ventures. This can include films or slides 
to be loaned out for educational use, free reprints and leaflets. 
ENDOWMENT INVESTMENT FUND — The endowment. investment 
fund is a reservoir for insuring the continued existence of the society. 
The interest from the investments is used in the general fund, but 
never the principal. Securities and trusts would automatically become 
a part of this fund. 
What better way could you find to honor those among us who 
have passed on? Help the aims of our Society through a Memorial 
Donation.
