Spealcing Tine: 10 Minutes. 



M2I0UNCia.ffiNT ; And now for o-ux talk with Uncle San's Naturalists. The United 

 States Biological Survey has been busy for sono years now trying to provide stop- 

 over privileges for uLgratory birds, especially duclcs and geese. Today we are 

 going to hear a little about that work to save our wildfowl. 



Mr, Arthur A. Riener, land valuation engineer of the United States Bio- 

 logical Survey, tells us about our national chains of landing fields for ducks 

 and geese. 



We call then our ducks and geese; but nany of than, were hatched in 

 Canada, Many of "our ducks" have their hones far up in the Arctic Circle, Many 

 that our dude hunters niss this fall will go back to their northern nesting 

 grounds to raise new fauilies next spring, Tild ducks are true ni grants. In- 

 ternational and State boundary lines nean very little in tiieir young lives, 



Sone nest along the northern edges of Canada and Alaslca. The nesting 

 sites of others are scattered throu^ the vast stretches of western Canada, And, 

 of course, we also have sone very extensive areas in tliis country where ducks 

 and geese nest as well as rest and feed. 



You probably heard a few weelcs ago that the fanous Bear River Marshes of 

 the north shore of Great Salt Lalce, Utah, had been fomally taken over as a 

 Federal bird refuge. 



Those Bear Hiver Marshes arc one of our big concentra.tion points for 

 ducks. That is a nesting site for nany ducks, but with the cliange of the seasons 

 ducks hatched in that area hop off for other States and other countries. Ducks 

 banded by workers of the Biological Survey on those narshes have been recovered 

 in 14 different States in our Great Basin and Rocky Mountain and Pacific Coast 

 country and in Canada and Mexico. 



In noving back and forth between their breeding and winter feeding grounds, 

 ducks and geese follow definite travel routes. In nost cases probably the sane 

 travel routes that were followed by their ancestors long before duck shooters 

 ever cane on this continont. 



Tear after year the ducks nove down in the fall fTon their gunner hones to 

 their favorite winter feeding grounds. But year after year, nen have been chang- 

 ing the conditions along sone of the chief rlgration routes of our waterfowl.
