Rainbow trout feeding

Trout sip the tiniest mayfly duns, imitated on a hook that is too small to grasp but sticks to the moisture on your finger. They eat leeches and elvers, voles and lemmings in the arctic, and each others’ young. I thought I understood their ferocity, in contrast to their daintiness and suspicion, until I saw a brown trout underneath some cliffs on the Yellowstone, gulping down the swallow nestlings that fell from above. The only other animal I’ve seen eat young swallows was a Kodiak bear who scraped them directly from the cliff face and ate them like M&M’s. The trout was in good company.
