“…Although shorebirds in the Central Valley also use evaporation and sewage ponds (Shuford et al 1998), we did not include these areas as potential habitat because they are known to expose shorebirds to extremely concentrated trace elements, salts, contaminants, and diseases (Ohlendorf 1993;CVJV 2006;Murray and Hamilton 2010;Davis and Hanson 2014), and some evaporation ponds are actively managed to discourage shorebird use (Davis and Hanson 2014). We also excluded alfalfa fields because we considered alfalfa generally too dense to be accessible to most shorebirds over the majority of the growing cycle, and they were not adequately surveyed by Shuford et al (1998).…”

“…These areas are valuable for the conservation of rare bird species such as the black-winged stilt (Himantopus himantopus L., 1758), a representative of the Recurvirostridae family included in the Red Data Book of Ukraine. This is a large wader with contrasting plumage patterns, inhabiting wetlands of tropic, steppe, desert and semi-desert landscapes of Eurasia (Abdillah et аl., 2012;Davis & Hanson, 2014;Pierce & Kirwan, 2020).…”

A stable group of birds has been formed at water treatment facilities. Sewage treatment sites are a well-known nesting place for long-legged waders. Black-winged stilts are included in the Bonn (Appendix II) and Berne (Appendix II) conventions, the AEWA agreement. Listed in the Red Book of Ukraine (1994, 2009) (status – vulnerable). In Ukraine, it is under protection on the territory of the natural reserve fund. The arrival of black-winged stilts waders at the nesting sites was recorded in the second-third decade of April (April 23, 2020; April 17, 2021). Immediately after returning to the nesting areas, the birds begin to build nests and lay eggs. The first eggs in this population were seen on 01.05.2020, 07.05.2021. The process of laying eggs lasted until the end of the first decade of July (08.07.2020). The average clutch size in the nests of Himantopus himantopus decreased from 3.8 ± 0.1 (2020) to 3.5 ± 0.1 (2021). The average egg sizes and their limits have been determined for long-legged waders. The chicks hatched from late May (30.05.2020), throughout June to the first decade of July (02.07.2020). The chicks were able to fly in a month – 29.06.2020. The muddy site of the wastewater treatment ponds of Kharkiv supported Black-winged Stilts until early August. Later, the birds started post-breeding movements. The last adults with juvenile birds were observed on 13.08.2020. Stilts in some years may stay until early October. The reproductive success of the black-winged stilt increased from 35.6% (2020) to 38.8% (2021). On average, 1.3 ± 0.2 (2020) and 1.4 ± 0.3 (2021) chicks fledged from the nests. In 2021, the number of nesting stilts increased, which is apparently due to rainy weather at the beginning of the reproductive period. For the purpose of more effective protection, the nesting settlements of the stilt should be protected and the appearance of people in the nesting places should be prohibited.
