has been found so far of serious damage to birds and animals that feed on 
the killed crayfish, mussels and snails. Since the lamprey young stays in 
streams about 5 years before moving into the Great Lakes, the chemical 
has raised hope of eventual control. Fawks reported on the theory that 
insecticides, particularly DDT, have made bald eagles sterile and are en- 
dangering the species. His report paralleled a recent BULLETIN article. 
Kossack, a former I.A.S. director, has been working with Dr. Harold 
Hanson of the Illinois State Natural History Survey on a 10-year study 
of the dove in Illinois. In four years of continuous observations over.a large 
number of routes patrolled every Sunday from before dawn to noon, their 
findings have been that not more than 1%% of dove nesting in Illinois 
occurs after the dove hunting season starts in September. They have found 
so far that the peak dove population is between August 20 and August 30. 
Just before dove season opens, there is a marked drop in numbers, ap- 
parently the result of migration or dispersal of young birds out of their 
nesting areas. Birds banded in Illinois are frequently recorded far north, 
for example, in Wisconsin or Michigan. The main migration appears to 
go down the Mississippi, dividing at Louisiana and going in about equal 
numbers toward Texas or toward Florida and Georgia. Doves are subject 
to hunting from the time they get south of the Ohio river. In an informal 
session during lunch, delegates from birding groups concerned about dove 
hunting while young are still in the nests conferred with Kossack and 
agreed that unless they can produce evidence that nesting is on a greater 
scale at the start of hunting season than the Kossack-Hanson findings 
indicate, they face a tough battle in trying to get the start of hunting 
season delayed. Several said they would instigate nesting surveys by the 
groups they represent. 
The Saturday afternoon program included two simultaneous round table 
discussions. One was on “pesticides and wildlife,’ moderated by Elton 
Fawks; the other on billboard control under the new federal highway pro- 
gram, moderated by Raymond Mostek, recording secretary of the N.R.C.I. 
and conservation vice president of the I.A.S. The pesticides round table 
was concerned chiefly with wildlife destruction by spraying to control Dutch 
Elm disease and how local authorities can be induced to follow recommended 
methods. The billboard question got a good airing from both sides, with 
the assistant attorney general of Illinois, Matthew Lear, and several of 
the delegates pitted against Dick Turnroth of Sterling, Ill., operator of an 
outdoor advertising firm, who has been chief lobbyist against billboard 
control at meetings of the Toll Road Commission. 
At the business meeting, bylaw changes to clarify the status of N.R.C.I. 
as strictly a forum for open discussion of problems with no power to bind 
delegates or the groups they represent were adopted. New officers are — 
Chairman: Dr. Robert A. Bullington of DeKalb and the Nature Conserv- 
ancy; Vice Chairmen: J. W. Galbreath of East St. Louis and the Cahokia 
Nature League, and William Carrigan, of Boone Anglers, Inc.; Treasurer: 
R. M. Rodrian of Caseyville and the Cahokia Nature League; Recording 
Secretary: Raymond Mostek of Lombard and the Illinois Audubon Society; 
Corresponding Secretary: Mrs. Jane Tester of Rockford, also I.A.S.
