This is one big reason I love our forum. We can all voice our thoughts and opinions. Then people come to their own conclusions. If we start looking at the math, none of it makes sense. Birds eat birds, birds eat insects and fish, insects and fish eat fish, fish eat insects and sometimes birds.
My main point is the improbability of an egg being successfully (meaning it doesn't dry out, get squished, or be otherwise destroyed) moved by a bird AND landing in a virgin pond AND landing in an environment where it can hatch AND then another one of the opposite sex go through the same process, then meet each other, make love and populate a pond.
I think that scenario certainly isn't impossible. I've seen Nature do some pretty weird things (Read the story about the guy whose pond was douched by Hurricane Ike). But, I believe that more than 99% of ponds "stocked" by Nature happened by fish swimming from one water body to another.
That's what I'm saying.

Hey Cecil, I knew you were typing at the same time I was. Just so happened my post beat yours by three minutes.

Carry on, Pond Boss Forum faithful! Bring on those deep thoughts and opinions, pepper them with facts and we'll all come to a healthy conclusion. It's our own spice of life.
