Slikken van de Heen

province Zeeland  >  Netherlands

This place has two faces: tidal mudflads and shorebirds on one side and a on the other side formal tidal area turned into a freshwater bird paradise.

Added by Leo Linnartz


The tidal mudflats harbour thousands of waders, ducks, geese and gulls, like Eurasian Curlew, Common Redshank, Common Shelduck and Brent Goose. Many hop over the dyke and visit the shallow fresh waters on the other side, augmenting the already huge numbers of ducks, geese and grebes, including Black-necked Grebe and Slavonian Grebe (Horned Grebe). Spoonbills breed here in a colony they share with Herring Gull and Lesser Black-backed Gull. The  White-tailed Eagle  breeds on one of the wooded islets. On the fresh water part there are two trails running through open forest and along creeks with a bird hide. Konik horses, wild cattle and (in near future) wisent graze here, and with luck, one might see pine marten. Common NightingaleGrasshopper WarblerEuropean Stonechat, Bluethroat, Common RedstartBullfinch and Northern Goshawk breed here together with many other species. Patches of reed contain Sedge Warbler and Reed Warbler. Wooded watersides are occupied by many Cetti's Warbler



Take the N257 to Sint Philipsland. There is a roundabout at the turnoff towards the little town. At the roundabout you can take a small parallel road that takes you north for circa 700m where further access with your car is prohibited. You can park your car there and start walking the trails through the forest (stairs up the dyke give access to them), or continue by foot or bike on the tar road, which brings you to the shallow fresh water lakes. Where the road crosses another dyke, you can view the tidal flats to the west. When you continue further, you will reach a point where you can cross the N257 to visit more mudflats on the salty west side. Do so, but be carefull when crossing the main road as cars drive fast here.

Since the tar road is very long, access by bike is advised. One could also drive with the car to the north and park near the big look out tower near the Sluices and walk from there.

This birding site ends here, but you can continue and more birds and birding places follow soon.
