Beschrijving
The NSG Rieselfelder Windel is a flat, open landscape where former sewage-irrigation fields have turned into a patchwork of wetland and farmland. Shallow ponds and reed-fringed basins alternate with wet grassland, ditches and open fields, so you can scan both water and open country in one visit. The open terrain offers long sightlines and makes it easy to pick out birds even at distance.
In spring, the ponds and muddy edges can hold waders, such as Kleine Plevier. Wetland birds like Waterral and IJsvogel are regularly observed, and the area also attracts raptors, including the occasional presence of Bruine Kiekendief. Breeding-season passerines include Tapuit, Tuinfluiter and Roodborsttapuit, along with non-passerines like Koekoek.
In summer, the site remains rewarding: the ponds host ducks such as Wilde Eend, Kuifeend and Krakeend, while reedbeds continue to hold singing Kleine Karekiet and Bosrietzanger. Open-country species like Kievit, Boerenzwaluw and Huiszwaluw are often present, and hunting raptors such as Torenvalk and, with some luck, Boomvalk can appear over the fields.
During autumn migration, the mix of water and open farmland really shows its strength. Expect increasing numbers of ducks (e.g. Krakeend, Wintertaling, Slobeend, and occasionally Smient) as well as reedbed species such as Waterral. Passerine migration can bring gatherings of finches like Putter. Large movements are possible too, with Kraanvogel sometimes observed in the area. Raptors are a constant highlight, with regular Buizerd and occasional scarcer birds such as Sperwer.
In winter, the ponds concentrate waterbirds: flocks of Wintertaling and Wilde Eend are typical, with Grote Zaagbek also recorded and Aalscholver as a quite stable presence. Reed edges and wet vegetation can hide Bokje and Houtsnip, alongside Watersnip. The surrounding trees and hedges can hold winter finches such as Keep, Goudvink and even Appelvink, as well as winter visitors like Koperwiek. A particularly nice winter specialty that is sometimes - although rarely - observed, then, is Baardman.
What makes this site special is how easy it is to combine wetland birding with classic open-country scanning in a compact area close to Bielefeld. A network of paths and viewpoints lets you explore quietly: spend time scanning the ponds and reed margins for rails and snipe, then walk the field edges for chats, pipits and hunting raptors.

The reserve can be reached easily by car via the A33 motorway (exit Bielefeld-Senne or Schloß Holte-Stukenbrock), followed by a short drive on local roads toward Windelsbleiche and Niederheide. Small parking possibilities are available at the Biological Station Gütersloh/Bielefeld, located in the area, and in some other spots. Click on the P in the map for directions.
Public transport is possible from Bielefeld with bus connections toward Windelsbleiche or Senne, followed by a short walk or bicycle ride to the reserve. The nearest bus stops are indicated in the map.
The best way to explore the area is on foot or by bicycle. There are several good viewpoints along the water basins and field edge, as well as some observation towers and hides, also shown on the map.

The reserve also hosts the headquarters of the Biological Station Gütersloh/Bielefeld, located in a former farm building. The station manages and monitors several protected areas in the region, including the Rieselfelder Windel, and occasionally offers environmental education activities.
