George: No apology needed, as I never even noticed any "thread killer" actions. I'm open to learning all I can about HSB. I want CNBG and RE for kid fishing, along with Tilapia for weed control and to reduce feeding. I need a tasty predator, with a low or no reproductive rate, so I'm investigating HSB, over female LMB. If even one male LMB got in there...
Besides fishing pleasure, I want to be able to eat all fish species in the ponds.
All: BTW, twice, I have seen birds drop fish in ponds, that did not come from the pond they were dropped in. Both times were because of a Mockingbird harrassing them.
