“…The number of wild oriental white storks has declined sharply past decade, with approximately 1,000–2,499 mature individuals globally ( IUCN, 2020 ), and this species is listed as nationally protected animals in China ( Itoh et al, 1997 ; Cardoso et al, 2016 ; Han et al, 2016 ). Conservation of C. boyciana is of great significance and considerable efforts from various research fields have been conducted in this endangered species (e.g., Liu et al, 2008 ; Han et al, 2016 ; Wei et al, 2016 ; Cheng et al, 2020 ). However, the environmental influence on the intestinal flora of oriental white storks have yet to be elucidated.…”

The oriental white stork (Ciconia boyciana) is considered an endangered species based on the International Union for Conservation of Nature (IUCN) Red List. This study presents the first evidence on comparative analysis of gut microbial diversity of C. boyciana from various breeding conditions. To determine the species composition and community structure of the gut microbiota, 24 fecal samples from Tianjin Zoo and Tianjin Qilihai Wetland were characterized by sequencing 16S rRNA gene amplicons using the Illumina MiSeq platform. Firmicutes was found to be the predominant phylum. Analysis of community structure revealed significant differences in the species diversity and richness between the populations of the two breeding conditions. The greatest α-diversity was found in wild C. boyciana, while artificial breeding storks from Tianjin Zoo had the least α-diversity. Principal coordinates analysis showed that the microbial communities were different between the two studied groups. In conclusion, this study reveals the species composition and structure of the gut microbiota of oriental white storks under two breeding conditions, and our findings could contribute to the integrative conservation of this endangered bird.

“…There was usually one such additional bird (46% of cases), but the mean number of co-foraging storks was 9.3 (max = 68 ind.) and the distance between neighbouring birds was ca 10 m at most (as in Cheng et al 2020). Only adult birds, probably from both the breeding (feeding chicks at this time) and non-breeding populations of storks, were recorded.…”

Human activities often negatively affect the time birds spend on activities such as parental care, foraging and resting. Forms of antipredator behaviour among birds such as vigilance can be an adaptation to human disturbances which can enhance their fitness in human‐managed habitats. We studied the flight initiation distance (FID) of White Storks Ciconia ciconia foraging on hay meadows during their breeding season. Our study showed that farm work, the type of meadows and starting distance (the distance between the bird’s position and the observer at the start of his walk) all had an influence on FID. Conversely, the numbers of storks in a particular foraging flock had no effect on an individual bird’s FID. The lower FID could have been due to the presence of machinery operating in the meadows, because storks then have opportunities to catch energy-rich prey that has been scared off by the machines. Unlike meadows cleared of hay, mown meadows with cut grass are more attractive to storks, and the FID there is shorter. The starting distance positively affected stork responses. These findings suggest that the FID of White Storks, treated as a measure of the risk of predation, depends largely on the degree of attractiveness of the feeding grounds.

“…The functional requirement of tactile foraging strategies is high permeability, which is influenced by morphological characteristics. Shorebirds usually assemble in mixed‐species flocks and feed on various wetlands (Cheng et al, 2020 ). Foraging‐based ecological niche separation in shorebirds (Baker & Baker, 1973 ; Novcic, 2016 ) has aroused widespread interest.…”

The coexistence of species with similar ecological niches is one of the core interests of community ecology research. However, how functional feeding traits, including bill size and leg length, determine the niche of mixed flocks of shorebird species has seldomly been studied, as well as, microhabitat variables affect the spatial patterns of availability and the quality of patches for wintering. From October 2016 to March 2017 at Shengjin Lake, Anhui Province, China, we recorded 226 scan samples from the different microhabitats and 93 focal animal videos of four common shorebird species: common greenshank, spotted redshank, Kentish plover, and little ringed plover. We found that the species participating in the mixed groups were different in each microhabitat. The results of the overlap index for microhabitats and foraging techniques between the species were consistent with the morphological characteristics of these species. Kentish and little ringed plovers had the highest Pianka's niche overlap index values of 0.95 and 0.98 for microhabitats and foraging techniques, respectively, whereas common greenshank and spotted redshank had values of 0.78 and 0.89, respectively. Common greenshank and spotted redshank used four foraging techniques: a single probe (PR), multiple probes (MPR), a single peck (PE), and multiple pecks (MPE). Kentish and little ringed plovers only used PE and MPE. The mean bill size, mean leg length, and mean foraging frequency were significantly associated with water depth. The mean bill size and mean leg length were both significantly correlated with the mean foraging frequency of shorebirds. The vegetated area was the most important variable for grouping among shorebirds. We concluded that the four species showed differences in their preferred microhabitats and foraging patterns. Interspecific morphological differences, including bill and leg lengths, resulted in niche differentiation. Thus, effective resource allocation by regional species was realized, and a dynamic balance was achieved by the mixed foraging species. The information on foraging behavior and habitat requirements could be useful in the management of water levels in natural areas and conservation of a diversity of wintering shorebirds.
