Birds can drop fish after they've captured them. Not longer than a year now, we were visiting my wife's family, and me and my father in law got to Walmart there was a dead fish in the front, but when we mentioned it to my wife who got there before us (separate cars) she said it was struggling for life when they saw it, I don't think there was a lake nearby enough, but I wouldn't be surprised if birds have accidentally introduced life into new bodies of water.

Yeah, but at least two live fish (a male and female) being dropped into the same remote lake, then finding each other at spawning time seems increasing implausible. Never say never, but ... Apparently some fish species do have small sticky eggs that can stick to the legs of water fowl, or even (with very small probability) pass through them intact, so this seems much more likely. Maybe a group of ducks feeding in one place then flying off to another?

    To the best of my knowledge fish eggs are fertilised outside the body

      Not all. There are many internal or quasi-internal fertilization oviparous species. And, in sharks at least, ovoviviparous and even placental species

More likely is that birds move fish between bodies of water because of fish eggs they carry on their bodies. This is how most bodies of water become supremely populated in Texas. In Texas all ground water sources, other than 1 lake on the far east side, are created by people in recent decades and almost all of these bodies are full of fish that did not get there on their own.

  most of them are populated thanks to explicit efforts from the government.

I see Texas multiple times and Norway zero times. What is the confusion causing your question?

  the streams aren't man-made and have tons of native fish species that also live in the impoundments now

I once found a recently-dead minnow in the outfield where I was playing software. That was a weird one.

  I've heard of remote work before but having you play software in the outfield seems a little extreme...

Interestingly, it is not always the case that birds can drop what they catch. I never knew this until I watched an eagle struggle to shore after it caught a fish that turned out to be too large for it to fly off with or do what it needed to do to be able to release the fish until it got to land. I have no idea about the swimming ability of an eagle but they certainly can't swim when they have a large fish in their claws, it was quite the struggle for that eagle to get to shore. https://www.raptorresource.org/2021/01/22/racheting-raptor-toes-an-upside-down-eagle-at-great-spirit-bluff/ https://www.raptorresource.org/2021/01/22/racheting-raptor-t...

  Oh yeah, they have a kind of ratchet on the tendons. It needs the load to be on terra firma for it to let go
  - ofalkaed 3mo ago
    They don't need to be on the ground to release as a rule, there are just situations which make it very difficult or impossible for them to release without being on the ground. The bald eagle courtship would be suicide if they could not release while in the air. For light loads they are quite good at releasing stuff in the air and will pass nesting materials and food to each other while in flight. https://youtu.be/gGjPrX84SMU https://youtu.be/gGjPrX84SMU
