Description
The area contains huge areas of water plants, that fish use for spawning. Both the billions of plants and young fish attract 10 of thousands waterbirds. Groups of more than 1000 Лысуха, 1000 Серая утка, 1000 Широконоска, or 50 Черношейная поганка are not uncommon. Серощекая поганка breeds here and Черноклювая гагара winters every year with upto 3 individuals. During spring migration 1000s of swallows or swifts can use this site as a stopover, especially in adverse weather. Гоголь, Морская чернеть can be found between the many ducks and the area is a major sleeping area for Длинноносый крохаль. The islands hold good breeding bird colonies with Большой баклан, Большая белая цапля, Малая белая цапля and Серая цапля. Also many Белощекая казарка and Серый гусь breed there, as well as many ducks. Южный соловей, Соловьиная широкохвостка and sometimes Обыкновенный ремез breed on the islands. Канюк and Тетеревятник breed on the islands and wintering Орлан-белохвост are present and several individuals use the area for sleeping.

Access
Go to the tiny harbour of Oude Tonge and from there south towards the Suisendijk. At the end of the Suisendijk the road goes down towards a small recreation field and car park. On foot or by bike follow the cycling path on the dyke to the west. You can continue until the Grevelingen dyke and even beyond.
P.S. good birdwatching starts already before the car park, as the vantage point from the sluices gives a good view on the roosting site of the Орлан-белохвост and the canal and harbour may hold Луток and Большой крохаль.
Access from the other side is also possible: Take the N59 from Oude Tonge towards Bruinisse. Take the turnoff towards Sint Philipsland. At the roundabout take the side road back towards Oude Tonge and drive beween the N59 and the Krammer lake on a small road, the Zuiderlandse dijk. Birding from your car is possible on that stretch, but be carefull, as more traffic uses this road. Continue untill the road turns right (east), away from the N59. Park your car on the right, just before the road bends back towards the left.
