Is Spring Extinct?

Well if you want to see hirundines this spring then I guess you need to be inventive.  This one seemed quite settled at the Natural History Museum on Monday.

There is an exhibition on Extinction currently showing - all a bit Jurassic Park and likely to engender those who wont bother to much if we lose the odd species knowing we can re-engineer them at some point in the future.  I wonder where they will put them and what they might feed on?  And what species would you want to bring back?

Be nice if they can grow a few of these though?  CAT F?
