Learned Something New

[Lard Almighty]

I actually did a research paper in college about invasive fish species, and learned that the green sunfish can take over 1st and 2nd order streams (read:headwaters) because they are so aggressive and can eat larger forage than the native fish (and the native fish themselves). In larger rivers, though, they are just another menu item for the predators.

that's interesting, i do happen to see greenies way up into tiny creeks sometimes. often though native redbreast are still mixed in. creeks flowing out of dams/ponds for example.
