The Rotterdamse Hoek is a fairly large and diverse area consisting of a small forest, several larger ponds with reedbeds and a large wetland area, which attracts many species of waterbird during the winter and breeding season. The small forest in the western part of the area surrounds a pond which originates from the construction (draining) of the Flevopolders. The strong pressure from the water of the IJsselmeer caused water seeping through the dyke, creating the pond. The small forest is a good spot for many species of songbird, but also Northern Goshawk, Long-eared Owl and Common Kingfisher.
Just east of the forest, four larger ponds are present which are in winter a great spot for many species of ducks. Large flocks of Tufted Duck, Common Pochard and smaller numbers of Common Teal are present. Scarcer species are often found within these large flocks, like Goosander, Smew and Greater Scaup. The surrounding reedbeds are great for Reed Bunting, Bearded Tit and Reed Warbler. Often, Water Rail can be heard and sometimes Great Bittern is present. In winter, flocks of Whooper Swan and Tundra Swan (Bewick's Swan) can be present.
The large wetland area on the northern side of the area are a great spot for migrating waders. Many species of wader are documented here. Common species, like European Golden-Plover, Black-tailed Godwit, Common Ringed Plover, Ruff and Little Ringed Plover can be seen. Scarcer species, like Grey Plover, Whimbrel and Temminck's Stint have been seen here too. Large numbers of gull can be present and sometimes species like Caspian Gull can be seen within these flocks.
The area just outside the dyke is a great spot for large flocks of foraging Common Goldeneye and Great Crested Grebe. Smaller numbers of Goosander can be seen here too. Caspian Gull often passes by.
The area is easy accessable. Next to the main road, a small parking lot is present. There are multiple tracks through the area and several information boards are present.
