birds have bean reported. 
cTora these notes we learn that after leaving Utah part of the pintails 
go to California to winter in the interior valleys, while others oross to the 
Great Plains ami go southward to the Gulf Coast in fossae* She spring nAgra- 
tion carries these latter individuals northward through the plains again* east¬ 
ward as far as western Missouri north at least into southern Canada* Sprit® 
records in the Missouri Valley drainage in the united States ©eased after 1315
