Dear 1r. Oehmcke: 
I am not aware of any special .tudy of the 
feeding habits of the Old iquaw duck:3."4 I be- 
lieve J. ,lark *alyer, II, wa including this 
species in his studies of the ioible fish pred- 
ators, but his 6tudies were interrupted three 
year', -go :when he joined the staff of the Biolog- 
ical .urveyr 
2At present, Karl Lagler is pursuing the fish 
predator studies, sponsored jointly by the merican 
ildlife Institute, the Uichign Conserv.tion JA- 
p-lrtment, the UniversAty of 'ichigan, and aided 
by certain manufcturers of fishinrg tackle. I"ut 
so iar as I know he is not paying special attention 
to the feeding, habits of the Old -quaw. 
.About seven ye-rs ago through arrangements 
I had made with comercial fishermen, the University 
:useums received several do7en Old  quevs which had 
been taken in ne,- a-t  7naw 7ay, but the stomachs 
had not been examined :t the time I corn; leted 
!Qhirsn  -terfowl     neent. I recorded just one 
"stomach1 which contained 450 mid  a rvae,    bird
