I'm starting to realise that I'm a bit of a migration obsessive. Every bird that flies over... it could be migrating... wow! Has it come from Moscow, Reykjavik, Tallinn, Gdansk or Rotherham? Amazing feats of avian endurance are around us all the time.
When I saw this poster for sale on the New Jersey Audubon Society website, I could barely resist it. To receive one here in the UK, the cost is $50 plus $10 shipping, which works out at a bargainous £29.77!
