One of the things birders like is when a poor bird gets lost. It was trying to fly to Newfoundland and winds up in Scotland.
(In the U.K. "twitcher" was a derogatory term for people who chased those birds and trampled all over people's property on the way).
We now know why migratory birds (and sometimes local birds) get lost: Space weather. Solar flares can interfere with their ability to navigate using the magnetic field and cause them to wander way, way off course.
There have been instances of these lost birds getting help from the handy humans to get back on track...by hitching rides on ships going the right direction. Apparently cruise ships going across the North Sea routinely have passengers too, but those birds are just being lazy and smart ;).
