bobad, are the minnows in the stump holes Gams? I can imagine that a pregnant female could release viable fry as she's carried over ponds in a bird's beak. If 3 or 4 fry made it into a remote pond it's highly likely they would successfully breed. I think the egg theory is possible but far less likely than live bearers spreading this way.
Yea, it was gams. There were a dozen or 2, and all the same size. It's a no-brainer how gams get transplanted in ponds. Bird ruptures pregnant gam, sticky mass of babies stick to beak, bird wades in barren pond, spears a swimming frog or snake, gams are rinsed off of beak.
