Swans are pure devil spawn.
They want to kill anything that moves near them. Sweet harmless baby ducks born on the pond? Initiate murder instinct. Man who feeds me and cleans my awful poop everyday? Start up the murder protocol.
Even the dumbest of invertebrates knew that we fed them and would be kinder. Swans see you bringing them food from across the park and are furious that "YOU STOLE MY FOOD I NEVER HAD AND PUT IT IN THAT BUCKET YOU'RE BRINGING TOWARD ME AND I AM GOING TO BEAT THE HELL OUT OF THIS GROUNDHOG NEAR ME BECAUSE OF IT, AND THEN TRY TO MURDER YOU."
Swans are the worst.
