true, i havent been specific enough. its about where they sleep or what they do when in standby mode. and for that GTPs will go up and hide between green leaves on a branch somewhere, and BPs go down into a rhodent burrow or something.
i really wonder how a hybrid will figure out what its supposed to do. sounds like there may be some seriously conflicting behavioral impulses.
im not really against hybrids, but you should at least pick species that have a comparable lifestyle.
