Theunis Piersma is onlangs gevraagd een statement te schrijven ter ere van World Migratory Bird Day 2013 (11-12 mei), een initiatief van de Verenigde Naties. Prominent in het stuk noemt Theunis King of the Meadows. Daarmee is de link gelegd tussen Kening fan ‘e Greide en VN-secretaris Ban Ki-moon, die zich bewust is van de bedreiging van ‘migratory birds’:
“I fully support the global campaign to raise awareness about the threats to migratory birds from habitat destruction, overexploitation, pollution and climate change. I call for greater international efforts to restore and preserve migratory birds and the network of sites they need to survive as an important part of the environment on which we all depend.”
– Mr. Ban Ki-moon, Secretary-General of the United Nations
