ana    to domostal fowl an wild birds.    ?rofessor Whitehead, 
working at the Uklahoma Agicultual £periaent StFtIon, was one 
of the ftmt investigtors to go Into this problem ve 
thooughly.   Se of the questions he sought to answer were 
1. Do birds boome iJrured from piekin, u'I noisoned bran? 
2, Do they suffer Ill effects from eating poisoned grass- 
hoppero? 
3,  Is thre any r#-l danger to humns or other aninals from 
eating ohickens thait have fed on poisoned grasshopper? 
irofessor Whitehead used domestio fowls and qual In his 
experiment. They were confined in pens and left without food 
for 24 hours. Poisoned ban was Wen scattered in pens at the 
rate of 100 pounds per icre and the birds were left for 24 hours 
with no other food. No Xndloations of any poisoning appeared. 
?rom this It we cnoluded that birds suffer no toxi     effects 
from picking up poisoned bran. Further studies were made usiag 
144 birds, Including ohiakens, turkeys, duaiks, quail, and Vie 
nestlings of various sDeies of son  birds. They were fed 
ap-proximately 17,000 poisoned and unvopon~@e4 grasshoprs,, the 
exeients being eftred over a 'perio of 10 to 66 d.ls. The 
followi   conlusions resulted for domestie fwls: 
1. rhey readily recognize that ooisanod gr akehoprs are 
not as desirable food " are uanrosoned grass1oppes8. 
2. They ate less than oihrf the naber of noisoned 
asshoppers     an they did the unpoisoned gra-sbopV#r.
