In our ponds the RES nest all around the shoreline. I never thought about a correlation to afternoon sunlight, but I will pay closer attention this weekend when I have more time.

Nesting strong right now, and the RES and BG's are side by side in the colonies as usual. Which may explain why we have such high numbers of BG x RES hybrids.

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
