There was once 107 hectares of agricultural land near Zevenhoven and the Nieuwkoopse Plassen. Those 107 hectares are still there, but the agricultural land has been transformed into a magnificent nature reserve named the Groene Jonker. A pond, reed fringes and grasslands were created, creating a bird paradise that attracts birdwatchers from far and wide. They are attracted to the many swamp and meadow birds that live there.

Which bird species you see there, depends on the season. Black-necked GrebeBlack TernBlack-tailed GodwitSpotted Crake and Baillon's Crake gave the area its fame. In spring you can see and hear Reed WarblerBluethroat Reed BuntingSedge Warbler and Water Rail in the reed collars. The European Marsh Harrier dances above the reed collars and Eurasian Spoonbill and Great Egret forage in the shallow water areas. You can also see waders such as Black-tailed GodwitCommon RedshankWood Sandpiper and Green Sandpiper. In winter you can see large groups of RuffNorthern LapwingEurasian Curlew and Common Starling, not to mention the thousands and thousands of Eurasian Wigeon that hibernate there. Other ducks you can see are Northern Shoveler and Northern Pintail. The Hen Harrier also hunts in the area, as do Peregrine Falcon and Eurasian Sparrowhawk.
