jb,
I have seen them cross in large ponds as well up to 65 acres. If the temperature went up at a steady rate the redear would spawn first starting at temps as low as 60 (once per year). Then bluegill would start a month later when temps hit above about 66 (then can spawn every month). Of course mother nature throws some curve balls and you may see them breeding at the sametime and this is when cross breeding may occur.
