Migrating waders were observed at the artificial ponds, BerezanRiver and ChichikleyaRiver in Nikolayev region. Counts were conducted during 336 days (spring - 106, summer - 175, autumn - 50, winter - 5) in 1990-2005. There were registered 25 species of waders. Breeding species are Lapwing, Little Ringed Plover, Black-winged Stilt, Common Redshank. Numerous species (101-200 records for all years) are Lapwing and Ruff. Common species (21-100) are Little Ringed Plover, Black-winged Stilt, Green Sandpiper, Wood Sandpiper, Greenshank, Common Redshank, Spotted Redshank, Marsh Sandpiper, Common Sandpiper, Snipe, Black-tailed Godwit. Scanty species (6-20) are Little Stint and Dunlin.
