(really feeling bad about myself. ...i've been discussing this on some other forums too. ...i can't beleive how much i have forgotten!!!!)

thank you for the reminder about owls regurdiating stuff. (one other person mentioned this.)

i'm going to go the library and get some books and then if that doesn't help, i'm going to call the DNR and see if they can spare me some time. (my internet search has been useless.)
if all else fails i'll use your wonderfully excellent plan.

...except i don't have a beaker, so i'll have to use a glass

Thank you for all of your help!
