This was , until a few years ago , a wonderful wetland , teeming with waders and wildfowl .
这个公园几年前还是一块美妙的湿地,到处是涉禽和野禽。
David paynter , reserve manager at the wildfowl & wetlands trust reserve at slimbridge in gloucestershire , says observers could also be seeing signs of a very late winter .
Still , don 't bet on open skies and porous borders for long-except maybe for the migrating wildfowl who currently function as an airborne influenza express .
