This piece developed the idea of fish in the trees - playing particularly on the discovery that trees along rivers, sometimes many kilometres inland upstream, often contain fish proteins. This was only discovered as DNA analysis became more sophisticated in recent years. It happens because of the predators (birds, bears and more) that catch the fish often leave parts of the fish uneaten, and the proteins move through the natural cycles of rainwater, microbes, fungi and into the trees.
