Between 10th and 20th January, the traditional International Waterbird Census (Midwinter Count), organized annually by Wetlands International, took place. In Romania the event is jointly coordinated by the Romanian Ornithological Society and the Milvus Group Bird and Nature Protection Association.
Due to the prolonged cold weather preceding the census, the water bodies were partially or entirely frozen in most regions. Thus, aquatic species have moved on large unfrozen reservoirs and rivers.

The program was attended by a number of 108 observers (ornithologists and volunteers), covering 238 wetland areas from 33 counties. In total 397,961 birds were counted of which 357,114 (89.7% of the total) were aquatic species. During the count, 147 species were identified, of which 60 species (40.8%) are considered dependent on wetlands.

The program was attended by a number of 108 observers (ornithologists and volunteers), covering 238 wetland areas from 33 counties.
