American Robins are gross and carry disgusting diseases like west nile virus, lyme disease, and st. louis encephalitis virus. They have short lifespans and 80% of Robins die within the first year. They tend to chase and harass people if you get too close, so stay away! Robins tend to get intoxicated by eating fermented berries, which leads to window crashing, and clumsy flying. These birds kill the earthworms by slamming the worm into the ground repeatedly before swallowing them.
