“…We measured the length and breadth of flooded eggs to the nearest 0.01 mm using digital calliper, and calculated egg volume (V e ) and Shape Index (SI) following Coulson (1963): V e = K × L × B² and SI = (B/L) × 100, where K = 0.482 (Calvo 1994;Hanane et al 2010), L is egg length and B is egg breadth.…”

“…Lysenko (1980) found 50% nest loss and 30% chick loss caused by livestock trampling for breeding colonies in Ukraine. For the Collared Pratincole Glareola pratincola , Calvo (1994) found high hatching rates in marshland colonies (88% of clutches hatched), but lower rates on farmland (29% hatched). Belik and Lebedeva (2004) and Belik (2004) suggest both nest failure and chick mortality to reach 60–100% in Black-winged Pratincole annually, but this is based on a study of ‘colonial waders’ in Central Kazakhstan and does not necessarily concern Black-winged Pratincole (Elkin 1981).…”

SummaryThe population of the Black-winged Pratincole Glareola nordmanni has declined significantly during the course of the 20 th century, resulting in a classification as 'Near Threatened' and 'Endangered' in the Global and European Red Data Books, respectively. Reasons for the decline are largely unknown due to a lack of information on the breeding ecology of the species. We studied breeding performance and habitat use of the Black-winged Pratincole in two areas in Kazakhstan and evaluated a new world population estimate. Colony size ranged from two to 180 pairs and differed significantly between the study areas. Mean breeding success was 1.30 6 0.16 (mean 6 SE) fledged chicks per breeding pair in Central Kazakhstan, and 0.59 6 0.13 (mean 6 SE) fledged chicks per breeding pair in NE Kazakhstan. Habitat types preferred were intensively grazed natural steppe, abandoned and fallow fields, shores of freshwater and brackish lakes and solonchaks (salt pans). Factors influencing habitat selection were quantified the first time for this species: the probability of occurrence of breeding colonies was highest near human settlements, within 3km of open water and where sward heights were low or intermediate, indicating a reliance on heavy grazing and water.Using data from six surveys across the whole breeding range, we calculated a new world population estimate of 76,000-95,000 breeding pairs, which is substantially higher than previous estimates. We discuss colony size, habitat use and population trends in the light of changing landscape conditions in the steppe zone and suggest an increase in habitat available to Blackwinged Pratincole due to an increase in the area of fallow fields and a change in grazing regimes since the collapse of the Soviet Union in 1991.

“…The majority of the colonies in agricultural areas were located in sunflower and cotton fields and occasionally in sorghum and chickpea cultivations (Calvo & Alberto 1990). However, breeding success was substantially lower as compared to in fields than in grasslands close to seminatural marshlands (Calvo 1994).…”

Nest-site selection and population trend of Collared Pratincoles (Glareola pratincola) breeding in agricultural habitats of the Nagykunság region (Hungary)

The Collared Pratincole (Glareola pratincola), which was once a typical breeding species of the sodic grasslands of the Great Plain, has become threatened with extinction from Hungary. It disappeared from the traditional grassland breeding sites before the 2000 and is currently breeding only in three sites in agricultural environments in Hungary. The objectives of our research were to find links between the use of shallow wetlands and the breeding behaviour of the species and to identify the characteristics of its breeding on ploughed fields. Data were collected between 2008 and 2016 as part of preparations for the conservation of the largest population which is found in the Nagykunság. We found a positive correlation between colony size and the area of the nearby wetland. We calculated the proportion of habitat-types used for nesting, and found that cultivated fields and fallow lands were the most important. Additionally, we also found that colony sizes were substantially smaller during the research period than those found earlier in the traditional grassland habitats. Finally, we found a positive trend in the size of the population during the research period.
