Shaka Fraser was trying to get some sleep before lectures at Lancaster University, but the hungry bird woke him up with incessant pecking on the glass.
Unable to ignore tapping sound, he threw out a few slices of bread to try distract the bird – only for it to attract another swan.
After more than two hours, the swan finally gave up and left Shaka alone only to return once he had come back from his lecture to carry on nipping at the window with his beak.
