Although these words mainly concern birds, areas which I described are valuable for other wildlife too, and nearly all of them are scenic areas suitable for anybody interested in leisure close to nature. Note, that birding in Poland is much less popular, than in the West, so in particular, large number of occassionally recorded species is an indication, that much more awaits discovery.

Place is mainly short-grass pasture, with sedge marsh, large reedbed and several pools.
The number of birds varies greatly depending from the water level. The largest number of birds appear when the water recedes and the area is patchwork of meadows and pools. At that time up to 3,500 geese and hundreds of ducks can stay, along with many scarce birds. Hovewer, these large flocks stay for 2-3 weeks and sometimes disappear just during the couple of days. Usually meadows are dry and relatively uninteresting from mid-May through the summer, when most of birds hide in the single large, impenetrable reedbed.
