Justification of Red List category
Although difficult to classify, the evidence of declines in parts of central Asia and the wintering range in south Africa, as well as projected declines in range due to climate change, indicate that this species has experienced moderate overall declines and may continue to do so, and thus warrants Near Threatened status under criteria A2bc+3bc+4bc.
Population justification
The current population is estimated to number between 150,000-190,000 mature individuals (Wetlands International, 2021). From the period of 2008-2019, the breeding population was estimated at 7,910-16,810 pairs, or 16,000-34,000 mature individuals, including Russia (6,000-12,000 pairs), Ukraine (10 pairs; BirdLife International in prep.), Kazakhstan (1,900-4,800 pairs; Kalyakin et al., 2020). BirdLife International in prep. estimates 6,000-12,100 pairs within Europe. It may be premature to revise the population estimate based on these recent low numbers, and so the current population size is retained at 150,000-190,000 breeding individuals. This estimate was previously attained from survey work in Kazakhstan suggesting a population of 76,000-95,000 pairs, roughly equivalent to 220,000-290,000 individuals in total. An even larger flock of 250,000-800,000 individuals in Orange Free State in South Africa in 1991 (du Plessis, 1995), as well as a flock of 76,500 birds at Vaal Dam, South Africa, in 2006 (University of Cape Town 2006) suggests the population may be (or might have been) even larger.
Trend justification
The European population is believed to be stable (BirdLife International in prep.), based on the Russian trend which holds 99% of the total European population. The population is believed to be decreasing in Ukraine (BirdLife International in prep.), and the trend is unknown in Kazakhstan (Kalyakin et al., 2020). The previous assessment of the European population estimated the rate of decline at 30-49% in 21.9 years (BirdLife International 2015), which equates to a 15-26% decline in 10 years (three generations). The species was reported to be increasing in central and north-east Kazakhstan and south-east Russia. Trends in Central Asia are likely to determine the global status of the species, and there is evidence that some colonies have disappeared (see below). Wetlands International (2021) states the trend is uncertain, and highlights the difficulty of estimating trends for a nomadic species. Given the stability in Europe and previous estimates of low-moderate declines, this species is likely to be declining at a rate of 1-19%.
Trends for the Asian population are poorly studied. There was a clear negative trend in eastern areas of the breeding range 1990-2000 going possibly along with a range contraction (e.g. Berezovikov 2002), but a slightly positive trend in some parts of South Asian Russia (Karyakin and Koslov 1999). At least since 2004, a positive trend has been observed in Akmola and Karaganda regions, Central Kazakhstan (J. Kamp et al. in prep.). At least since 2000, numbers have been increasing in Pavlodar region, north-east Kazakhstan, with a 20-30% population increase between 1998 and 2007 (Kamp et al. 2009; A. O Solomatin pers. comm.). This increase coincides with the massive increase of fallow and abandoned land in north-east Kazakhstan and European Russia. The European population (6,000-12,100 pairs) declined by over 50% during 1990-2000, with steep declines in European Russia (A. Mischenko in litt. 1999, Belik et al. 2000) and Ukraine (BirdLife International 2004). Greater availability of suitable habitat is likely to have lessened the declines now (Kamp et al. 2009), owing to the stable trend observed in Russia. Surveys in 2006 of 65,000 km2 in the Stavropolskii Krai, south-east Russia found a total of 1,800 breeding pairs (L. Malovichko and M. Koshkin in litt. 2007) in an area where only 100-200 pairs were estimated in 2004 (Belik and Lebedeva 2004). Declines were reported from the South African wintering grounds (Barnes, 2000). A count of 20,000 individuals in 2006 at Chagraiskoe reservoir, Manych, Stavropolskii Krai, south-west Russia represents one of the largest flocks in recent times recorded outside the wintering range (L. Malovichko and M. Koshkin in litt. 2007). It is clear that additional survey work visiting suitable habitat is required, especially in Kazakhstan and Asiatic Russia, but available evidence does not indicate that the global population is small or declining rapidly.
This species has a very large range, breeding in Russia, Ukraine and Kazakhstan and sporadically in Belarus, Hungary and Azerbaijan. It migrates to southern Africa, mainly Botswana, Zimbabwe, South Africa and Namibia, and irregularly to West Africa. It is now rarely recorded in West Africa, possibly indicating a dwindling 'sub-population' of breeding birds from south-east Europe that once wintered in larger numbers (Dodman 2002). Some birds winter in Ethiopia, as the observation of 5,000 birds at river Baro in January 1973 indicates (Ash 1977). Passage birds are regularly recorded in Cyprus, Turkey, Israel, Iran, Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, Egypt, Nigeria, Sudan, South Sudan, Ethiopia, Chad, Mali, Mauritania, Rwanda, Burundi, west Uganda, Cameroon, Democratic Republic of Congo, west Zambia and Angola. Non-breeding birds are also recorded in Libya, Lesotho, Niger, Morocco, Uzbekistan (rarely (S. Sklyarenko in litt. 2005)), Kyrgyzstan and Georgia (small flocks of up to 3,400 individuals recorded from the Choroki Delta [R. Sheldon in litt. 2016]). The population was estimated at 29,000-45,000 birds following country expert interviews during the Single Species Action Plan Workshop (Moscow, 2002) (Belik and Lebedeva 2004). However, this seems to be an underestimate and was probably based on incomplete coverage: the current breeding population has been estimated at 76,000 to 95,000 breeding pairs, based on five large scale surveys across the whole breeding range (Kamp et al. 2009). A flock of 250,000-800,000 birds in Orange Free State, South Africa, in 1991 (du Plessis 1995) and a flock of 76,500 birds at Vaal Dam, South Africa, in 2006 (University of Cape Town 2006) support these substantially larger figures.
Behaviour This species is migratory (del Hoyo et al. 1996). It nests in small to large colonies (5 to >500 pairs, occasionally thousands (del Hoyo et al. 1996)) from May to July (del Hoyo et al. 1996). Birds gather to moult after breeding in July and August, and then apparently migrate rapidly overland at high altitude to non-breeding grounds (Belik and Lebedeva 2004; Hayman et al. 1986). They depart between August and early October (Belik and Lebedeva 2004; Hayman et al. 1986), and arrive on their wintering grounds in October-November (Hockey et al. 2005). Migrating flocks of several thousand individuals have been recorded (Cramp and Simmons 1983). During the non-breeding season the species is constantly nomadic (del Hoyo et al. 1996; Cramp and Simmons 1983) and highly congregatory, occurring regularly in flocks of 10-100 (Cramp and Simmons 1983), and occasionally in foraging flocks of thousands (Cramp and Simmons 1983), often in association with Collared Pratincoles Glareola praticola (Hockey et al. 2005). It roosts at night in loose concentrations (Hockey et al. 2005). The return migration begins in March, with birds arriving on the breeding grounds from the end of April through May (Hockey et al. 2005). Habitat Breeding It breeds on grazed short-grass steppe, fallow and ploughed fields as well as on alkaline flats, sandspits, shell ridges and sparsely vegetated Solonchaks (saltpans) in lake depressions and river valleys (Belik and Lebedeva 2004; Hayman et al. 1986; Kamp et al., 2009; Hockey et al. 2005; Cramp and Simmons 1983). Large colonies always occur near water and damp meadows, or marshes overgrown with dense grass (Cramp and Simmons 1983). A study on habitat selection in Central Kazakhstan in 2006 revealed presence of livestock, vegetation height and the availability of water as key habitat features whereas vegetation type and topography had no influence (Kamp et al. 2009). Nonbreeding birds frequent open high-altitude glassland and mudflats (del Hoyo et al. 1996). Non-breeding During the non-breeding season it occupies seasonally wet grasslands, savannas, and sandbanks along large rivers (Belik and Lebedeva 2004; Hayman et al. 1986). It is also found at the edges of salt pans (Hockey et al. 2005). It can be found up to 1590 m a.s.l. (Ash and Atkins 2009). Diet It feeds on epigeic and airborne insects, particularly swarming species (Hockey et al. 2005). It takes locusts, orthopterans and coleopterans as well as wasps, bees, dragonflies, ants, termites, flies, ichneumons and cockroaches (Hockey et al. 2005; del Hoyo et al. 1996; Cramp and Simmons 1983). It responds quickly to insect emergence after storms (Hockey et al. 2005). Breeding site This species nests on open ground, usually near water (Cramp and Simmons 1983). The nest consists of a shallow depression of about 10cm diameter lined with small pieces of available vegetation (Cramp and Simmons 1983). Mortality of eggs and chicks strongly fluctuates and may reach 60-100% annually (Belik and Lebedeva 2004). Recent quantitative data from Kazakhstan indicate higher fledging rates with a mean of 0.5 fledged chicks per nesting pair in 2006-2007 (Akmola, Karaganda and Pavlodar regions) (Kamp et al., 2009). A study from the Caspian steppe showed the pratincole was subject to over a 90% nest predation rate (Kubelka et al., 2019).
Threats are poorly understood. Where declines are occurring the key factors probably relate to changing land-use practices such as conversion of steppe to arable agriculture in some areas (although much former agricultural land in Central Asia is now becoming fallow and grazed areas provide new breeding habitat), shifts in arable land versus livestock grazing on semi-natural steppe in others, and agricultural operations, such as harrowing. A study in Kazakhstan by Kamp et al. (2009) reported that the species is largely dependent on the presence of large grazers and declines occurring from the end of the 19th century in Ukraine and European Russia have been associated with the increase in ploughed areas and the loss of grazed steppe (Kamp et al. 2009). Nest trampling by livestock might influence breeding success at the Kazakhstan strongholds (Kamp et al. 2009). In some areas, predation by corvids, foxes and hedgehogs may affect breeding success (Belik and Lebedeva, 2004; Kamp et al. 2009). In the wintering grounds, agricultural practices and grassland degradation may have reduced the area of available habitat, and locust control measures may also have negative impacts (Hockey and Douie, 1995) both in terms of loss of a food source and the impact of pesticides (del Hoyo et al. 1996). Hunting is also likely to threaten the species (R. Sheldon in litt. 2016). Whether regional climate change, as proved for Pavlodar region in northern Kazakhstan, affects the species negatively or positively, is largely unknown (A. O Solomatin pers. comm.) but it is likely to influence distribution and abundance. One study has projected a 49% net reduction in the species' wintering range by 2050 due to climate change, with a 45% and 54% reduction in the current passage and wintering range (Nagy et al. 2021). Savitsky (2019) suggested summer rainstorms and severe droughts may have contributed to declines. The relationship between vole abundance and steppe bird population productivity may also include black-winged pratincoles, and with periodicity and abundance of voles across temperate Europe changing, this may be an emerging threat that requires more research (Kubelka et al., 2019).
