By using geo-locators we
have in recent years been able to reveal a most spectacular migratory behaviour,
that of the great snipe. In late August, males of this medium-sized wader bird
leave their breeding grounds in central Sweden and embark on a long and fast
direct flight to sub-Saharan Africa. They then fly on average 5500 km in 2½
days, at an average speed of about 90 km/h. One individual was estimated to
have flown 6900 km over 2½ days, at a speed of 115 km/h.
The combination of
distance and speed seems to be a “world record” among migrating animals and
when the first paper was published in 2011 it received a lot of media attention.
Apparently, the great flights have now also reached the fantasy genre. In “The
Magician’s Land”, a fantasy novel from 2014 by Lev Grossman, some of the
characters want to transform themselves to migrating animals, to be able to
reach Antarctica. One suggestion is they should turn into great snipes (!) and
then the amazing capacity of these birds is referred to in quite some detail.
It is nice to see how the
wonders of nature can fit so well into a fantasy novel. Facts from nature just
as they are. But given that “The Magician’s Land” is a real best-seller, and
therefore is read by many more people than our original paper in Biology
Letters, maybe there is a risk that the great snipe flights may soon be considered more fantasy than facts? (-:
“- I have heard that
great snipes fly thousands of km in just a few days”.

something written in a fantasy novel!
