"Sometimes
birds migrating along coastlines get caught in fog, and by the time
they can see again, they are far out at sea. Usually these lost birds
either quickly find land or end up dropping exhausted into the ocean.
Once
in a while, a bird stranded over the ocean does find a spot to land
and rest — on a ship or boat! Given a bit of fresh water, a bird
that was in good condition before migration could continue the flight.
Robins
navigate, in part, by using the Earth's magnetic field. It's possible
that this bird got turned around because its orientation system isn't
working well. We may never know exactly how this robin found its way
to Europe. But it's fun to wonder how it survived the trip, what adventures
it had, and whether it will ever find it's way home again!
