Descrição
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 Borrelho-pequeno-de-coleira. Wetland birds like Frango-d'água and Guarda-rios-comum are regularly observed, and the area also attracts raptors, including the occasional presence of Tartaranhão-ruivo-dos-pauis. Breeding-season passerines include Chasco-cinzento, Felosa-das-figueiras and Cartaxo-comum, along with non-passerines like Cuco-canoro.
In summer, the site remains rewarding: the ponds host ducks such as Pato-real, Zarro-negrinha and Frisada, while reedbeds continue to hold singing rouxinol-dos-caniços and Felosa-palustre. Open-country species like Abibe-comum, Andorinha-das-chaminés and Andorinho-dos-beirais are often present, and hunting raptors such as peneireiro-de-dorso-malhado / peneireiro and, with some luck, Ógea 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. Frisada, Marrequinha-comum, Pato-trombeteiro, and occasionally Piadeira) as well as reedbed species such as Frango-d'água. Passerine migration can bring gatherings of finches like Pintassilgo. Large movements are possible too, with Grou-comum sometimes observed in the area. Raptors are a constant highlight, with regular Águia-d'asa-redonda and occasional scarcer birds such as Gavião da Europa.
In winter, the ponds concentrate waterbirds: flocks of Marrequinha-comum and Pato-real are typical, with Merganso-grande also recorded and Corvo-marinho-de-faces-brancas as a quite stable presence. Reed edges and wet vegetation can hide Narceja-galega and Galinhola, alongside Narceja-comum. The surrounding trees and hedges can hold winter finches such as Tentilhão-montês, Dom-fafe and even Bico-grossudo, as well as winter visitors like Tordo-ruivo-comum. A particularly nice winter specialty that is sometimes - although rarely - observed, then, is Chapim-de-bigode.
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 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.
