* Age classification of broods on each beat-out used to compute 
total production, 
Because of the rapid deterioration of walter on this area, observations 
show that 436 pairs produced 84 broods, or a pair success of only 19 percent. 
Because of the heavy concentration of broods on large bodies of water surrounding 
this study area, the above figure cannot be considered an accurate appraisal of 
production on Area Il. There is no doubt but that broods moved away from this 
area in large numbers as the ponds disappeared.
