Conservation of Iberian Black Storks Ciconia nigra outside breeding areas: distribution, movements and mortality.
Summary
Seven out of ten Black Stork chicks fitted with satellite tags successfully made the journey from Iberia to the Sahel. Four died there during their first winter and one additional bird in the second winter. Our results show that 30% of the tagged fledglings died in Iberia and 50% (5/10) in the Sahel. In the Sahel, Black Storks occupy areas of seasonal rivers and small bodies of water in these sub-Saharan savannas, where they track suitable sites according to the progressive drying of the Sahel after the summer monsoon. This behaviour may make them more susceptible to coming into contact with humans and, consequently, current and future action plans for conserving the Iberian Black Stork population should link efforts with AEWA's Strategic Plan and other international initiatives to promote the global use of water resources for humans and wildlife in the Sahel.

Breeding density, spacing of nest-sites and breeding performance of black storks Ciconia nigra in Dadia-Lefkimi-Soufli Forest National Park, north-eastern Greece
Abstract
Breeding densities and the breeding biology of the black stork Ciconia nigra were studied in Dadia – Lefkimi – Soufli Forest National Park, northeastern Greece, during 2006–2008. One hundred and one breeding attempts were monitored during the 3-year study period. In total 271 fledglings were successfully raised during that period. Black storks arrived in the study area between the last days of February and mid-March. Mean fledging date was 16 July. An average of 3.26 fledglings per successful pair (n = 83) were produced. The mean nearest neighbour distance between occupied nests was 1.09 km (1SD: 0.94, n = 33). Nests containing fledglings were recorded as close as 228 m. The population density was calculated at 8.1 pairs/100 km 2 for the whole study area. The steady increase of the black stork population in the study area during the last few decades is partially attributed to the intensification of agriculture at small scale, which has created ideal feeding grounds for the species. The establishment of shallow artificial ponds in grasslands or along streams within the protected area may improve the availability of food resources for the species.

Study and conservation of Black Stork Ciconia nigra L. in Ukraine: 2005-2016
Abstract
The paper summarizes the results of 12 years of Black Stork studies and conservation in Ukraine. All the activities were conducted within the international project “Ciconia Ukraina” with the financial support from the “Ciconia” fund (Liechtenstein). During the study period, numbers, density and distribution of Carpathian and Polissian populations of Black Stork were estimated. The role of mature forests for breeding of Black Stork was assessed and the inventory of such forests in the Rivne part of Polissia was performed. Main threats for Black Storks in Ukraine were clarified and measures to overcome these threats were proposed. Special biotechnical measures were undertaken to protect individual nests. Demographic structure of the West Polissian population was revealed on a genetic level. Feeding diet of nestlings was studied. The eco-educative campaign among local communities and forestry workers has been carried out. The National Action Plan for Black Stork conservation was prepared.

the conservation status of Black Stork Ciconia nigra in South Africa, Lesotho, and Eswatini
Abstract
... Across South Africa, Lesotho, and Eswatini, long-term citizen science atlas data have suggested concerning declines in the population of Black Stork Ciconia nigra. Unlike the Asian and European populations, the southern African Black Stork population is described as resident and is listed as “Vulnerable” in South Africa, Lesotho, and Eswatini ... Here we report on surveys of historical nesting locations across northern South Africa, finding evidence for nest site abandonment and limited evidence of recent breeding. ... We noted that a large proportion of the population occurs outside the breeding range during the breeding season, suggesting a considerable non-breeding population, especially in the extensive wildlife refuge of the Kruger National Park. The slow declines observed might be indicative of a population which is not losing many adults but is failing to recruit significant numbers of juveniles due to limited breeding. ... Using densities derived from transect surveys, we used predictive models to derive estimates of breeding range carrying capacity and a population estimate, which suggested declines to numbers around 600 for this subregion. Minimising disturbance at breeding sites of this cliff-nesting species and improving water quality at key population strongholds are pathways to improving the status of the species in the subregion.
