Global warming. 😐
Yeah— caught that comment also— absolutely ridiculous for a single bird to go that far from normal range, and they come up with “global warming”. Falconer’s getting paid to scam for global warming more like. See post above yours here for a photo of a UK guy with a mature huge bird.
5K miles is the “over the Pole” route for a single bird to NS and then NH?— there being nothing to eat along the way if the polar route? Doubt seriously either overland/ocean routes. Hummingbirds, however do migrate over the Gulf of Mexico to Mexico (little bitty birds).
