“…This assumption is well founded in the literature. A number of reports suggest that these habitat types are favoured throughout the species' European range (Struwe & Thomsen, 1991;Carrascal et al, 1993;Schulz, 1998;van der Have et al, 1999;Johst et al, 2001;Moritzi et al, 2001;Antczak et al, 2002;Tryjanowski & Kuzniak, 2002;Tsachalidis & Goutner, 2002), and our own observations have confirmed this for southern Sweden (O. Olsson, A. T. Brelsford & D. J. Rogers, unpubl.…”

“…White stork largely depend on grasslands in agricultural landscapes as suitable habitat (Struwe & Thomsen, 1991;Carrascal, Bautista & Lazaro, 1993;Schulz, 1998;Johst, Brandl & Pfeifer, 2001), a trait shared with a large suite of declining farmland birds in Europe (Donald, Green & Heath, 2001;Gregory et al, 2005;Smart et al, 2006). Several studies have demonstrated a foraging preference for wet meadows and pastures, and recently cut hay meadows (Carrascal et al, 1993;Antczak et al, 2002), in addition to wetlands (Schulz, 1998;Dziewiaty, 2002;Tsachalidis & Goutner, 2002). The species has undergone a dramatic historical decline, particularly in the northern and the western parts of its breeding range (Schulz, 1998).…”

The loss of wetlands and semi-natural grasslands throughout much of Europe has led to a historic decline of species associated with these habitats. The reinstatement of these habitats, however, requires spatially explicit predictions of the most suitable sites for restoration, to maximize the ecological benefit per unit effort. One species that demonstrates such declines is the white stork Ciconia ciconia, and the restoration of habitat for this flagship species is likely to benefit a suite of other wetland and grassland biota. Storks are also being reintroduced into southern Sweden and elsewhere, and the a priori identification of suitable sites for reintroduction will greatly improve the success of such programmes. Here a simple predictive habitat-use model was developed, where only a small but reliable presence-only dataset was available. The model is based on the extent and relative soil moisture of semi-natural pastures, the extent of wetlands and the extent of hayfields in southern Sweden. Here the model was used to predict the current extent of stork habitat that is suitable for successful breeding, and the extent of habitat that would become suitable with moderate habitat restoration. The habitat model identifies all 10 occupied nesting sites where breeding is currently successful. It also identifies $300 km 2 of habitat that is predicted to be suitable stork habitat, but that is presently unused; these sites were identified as potential areas for stork reintroduction. The model also identifies over 100 areas where moderate habitat restoration is predicted to have a disproportionate effect (relative to the restoration effort) on the area of suitable habitat for storks; these sites were identified as priorities for habitat restoration. By identifying areas for reintroduction and restoration, such habitat suitability models have the potential to maximize the effectiveness of such conservation programmes.

“…Different farming practices and water levels have an effect on these competitors, determining where the rice is during and after godwit arrival. The question remains whether the waterbirds that are common in rice fields (Fasola & Ruíz 1996, Elphick & Oring 1998, Tourenq et al 2001 (Correia 2001, Marques & Vicente 1999 and the others are also known to be primarily carnivores (Lajmanovich & Beltzer 1995, Moreira 1995, Tsachalidis & Goutner 2002, Holland et al 2006. Our own study proves that typically carnivorous species can use rice grain as a seasonal food source; however, as all other bird species were present in very much lower densities, it is unlikely that they would have a depletive effect on the food available for godwits.…”

“…The overall diet of the White Stork is well known over its breeding distributional range (Mužinić and Rašajski, 1992;Tsachalidis and Goutner, 2002;Kosicki et al, 2006). However, information on the White Stork diet in Algeria is generally scarce, and mostly highlighted the diet plasticity and its role in the current expansion of the species in the country (Boukhemza, 2001;Moali-Grine, 2007;Djerdali, 2010).…”

Assessing feeding conditions and variations of diet composition over the breeding season is of great help in the understanding of the ecological niche of species. In meeting this aim, the White Stork's (Ciconia ciconia) diet was studied based on the analysis of 87 regurgitation pellets collected from Batna (Northeast Algeria). A set of 2138 prey-items were identified and classified into 61 different prey-species belonging to seven classes, 13 orders, 29 families and 51 genera. The White Stork has a diverse diet (food niche breadth, FNB = 14.5, Shannon index H' = 4.4 bits), mainly composed of arthropods, of which 94% of prey-items are insects that represent 8% of total prey biomass. The White Stork constantly fed on the remains of chicken foraged from rubbish dumps (biomass = 68.74%) and small mammals (biomass = 14.41%) as these prey categories constitute a source of high energy, particularly during the period of chick rearing. GLMs applied for diet characteristics revealed a significant variation in numbers of prey individuals between breeding phenological stages. While variations of other diet parameters (biomass, species richness, FNB, H', H' max and evenness) were not statistically influenced by breeding phenology. All diet characteristics were significantly correlated with the period of chick development, which is the key period for breeding success; suggesting an increase in parental investment and feeding effort. Our findings suggest that the White Stork performs a balance in order to satisfy its food requirements by compensating reciprocally between intake of prey numbers and their biomass regardless of the phenological stage of reproduction.
