It Is not known, however, just how much land these birds are utilizing 

 outside the township or how much of the 36 square miles would be suitable 

 sharp-tall habitat. 



Let us assume also that all birds do nest in the township and that 

 four of each brood reach maturity. We then should have by fall a 

 population of 8.5 birds per square mile. This, of course, is computed on 

 theory and assumption only. 

 Live Trapping and Banding 



A shortage of men and the fact that the walleye run coincided with the 

 time the trapping was done meant it was impossible to put in enough time 

 at it to produce total satisfactory results. 



The cannon nets were set five times each on a different date. 

 1st - Set - cannons had too much elevation and the birds flew before the 

 net settled over them. 



2nd - Set - the net caught in heavy stubble and thus pulled to one side. 

 "^rd - Set .- five birds were caught. Three were banded and released, 

 the other two were badly injured with broken wings. 



^th - Set - four birds were caught. Three were banded and released. One 

 was dead when taken from net. 



^th - Set - five birds were caught. Four were banded and released. One 

 had a broken wing. 

 Total number banded and released - 10 birds. 



1st, 2nd, and 3rd sets of nets were on a dancing ground holding 18 

 birds. The area was situated on a field of grain that had been cut by combine. 

 The heavy stubble proved to be a difficult area in which to set and release 

 the net without damaging it. 



^th and 5th sets of nets were on a dancing gro\ind of 12 birds. This 

 area was situated on a plowed field which proved an easier setting in 

 which to utilize the nets. Burlap bags were also used on the ^th and 5th 

 settings to cover the birds with until they were taken out from under the 

 net. This proved quite satisfactory as a means to quiet the birds and thus 

 prevent them from injuring themselves.
