Eggs on a Journey
by Christina Jarvis
Winter 2024-25
I heard about the theory that one way fish can spread to new bodies of water is when waterfowl eat fish eggs and then poop them out into new places. For example, this could be how a new alpine lake gets its fish. An ecology research group published a study (see links below) showing that the eggs of at least one fish species can survive transport through a bird’s digestive system.
When the “In the Air” call for submissions came out, I wanted to see if I could depict this idea in a single image. The fish deposits its eggs in the gravel bed, and the duck eats them and then flies to a new place with those eggs in his stomach, as shown by the zoom circle.
