Stuff found floating on lake / river water that should not be there

Describe the bug

You can find things floating on the river / lake surface that should probably not be found there. Mostly bird eggs and bird crap.

Steps To Reproduce

1. Find a lake or river
2. Swim, or boat around it
3. Find bird crap and bird eggs floating on the surface.

Expected behavior

Bird crap should dissolve into the water. Birds should lay eggs in nests, not in the water (you might get one or two in the water from floods or nest breakages, but not lots).

Screenshots

Good job breaking reality, geese.

Start by reproducing the reported bird eggs and bird waste on lake or river surfaces using the listed game version and tiles graphics. Review the related floating-in-mid-air issue #38066 and trace the world-object behavior responsible for items appearing on surfaces. Done means these objects no longer appear floating in water except in plausible cases such as flooding or nest breakage.
