Descrizione
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 Corriere piccolo. Wetland birds like Porciglione and Martin pescatore are regularly observed, and the area also attracts raptors, including the occasional presence of Falco di palude. Breeding-season passerines include Culbianco, Beccafico and Saltimpalo, along with non-passerines like Cuculo.
In summer, the site remains rewarding: the ponds host ducks such as Germano reale, Moretta and Canapiglia, while reedbeds continue to hold singing Cannaiola and Cannaiola verdognola. Open-country species like Pavoncella, Rondine and Balestruccio are often present, and hunting raptors such as Gheppio and, with some luck, Lodolaio 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. Canapiglia, Alzavola, Mestolone, and occasionally Fischione) as well as reedbed species such as Porciglione. Passerine migration can bring gatherings of finches like Cardellino. Large movements are possible too, with Gru sometimes observed in the area. Raptors are a constant highlight, with regular Poiana and occasional scarcer birds such as Sparviere.
In winter, the ponds concentrate waterbirds: flocks of Alzavola and Germano reale are typical, with Smergo maggiore also recorded and Cormorano as a quite stable presence. Reed edges and wet vegetation can hide Frullino and Beccaccia, alongside Beccaccino. The surrounding trees and hedges can hold winter finches such as Peppola, Ciuffolotto and even Frosone, as well as winter visitors like Tordo sassello. A particularly nice winter specialty that is sometimes - although rarely - observed, then, is Basettino.
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.
