Birds Sing for Empty Feeders

My dad whistles a specific melody when he comes to refill the bird feeders. The birds have started singing it when they're empty. this b▮h empty, TWEET Have any of you heard of the Harvard MIT Pigeon Prank? An MIT student dressed in a black-and-white striped shirt went to the Harvard football stadium every day of one summer, blowing a whistle while scattering breadcrumbs or birdseed to coax neighborhood pigeons down onto the field. At Harvard's opening game of the season, upon the referee's first whistle, it's said that hundreds of pigeons descended onto the field, causing a half-hour delay.

A screenshot of a tweet about birds learning to whistle the melody their feeder-refilling human uses. The joke is that the birds effectively tweet a profane complaint when the feeder is empty, followed by a story about pigeons being trained to invade a Harvard football game at the referee's whistle. It is shared as a reaction to situations where animals or people have learned a very specific cue and demand something immediately.
