Migratory bird ecologist Theunis Piersma investigates various wader species. ‘However, I do not restrict my research to just the Wadden Sea. That is because the Wadden Sea mudflats are no more and no less than a link in a far larger system. Via birds such as red knots, Eurasian spoonbills and bar-tailed godwits, the Wadden Sea mudflats are linked with Siberia, Greenland, Southern Europe and West Africa. Through these birds, everything we do here influences what happens elsewhere in the world, and vice versa.’
‘One of the birds with such an international effect is the bar-tailed godwit. In the breeding grounds in Siberia, the climate is warming up faster than anywhere else. This means that bar-tailed godwits have to arrive on the tundra earlier and earlier for their chicks to encounter the richest food supplies of insects emerging from the tundra. In the Wadden Sea, we can see this ‘being in a hurry’ by the speed at which the birds replenish their fuel stores in spring, the stores that carries them through 5000 km of nonstop flight to snow-covered tundra. Right here, en route from West Africa, they need to eat about half their body weight, which they mainly do on a diet of lugworms. Now, because the period they can remain here is getting shorter, they often depart underweight and therefore with a higher risk of perishing during the migratory flight.’
‘Sometimes, you learn the most about your own environment by comparing it with others. We therefore follow various waders on different migratory routes throughout the world, for example by using solar-powered miniature satellite-transmitters which regularly convey the birds’ geographical positions. For instance, we attach transmitters to bar-tailed godwits in the wadden areas of Guinea-Bissau, Mauritania, Oman, North-west Australia and New Zealand. Thanks to that international work, it has become crystal clear how unique the Wadden Sea is. It is a vital link for a great number of birds migrating between the Arctic region and Africa. Such knowledge reveals the global ecological network, but at the same time, it also places a particular responsibility on our shoulders for ensuring that the Wadden Sea is managed well.’Read more +
