摘要	Hitherto, virtually nothing is known about the microbial communities related to the bird species in the family Corvidae. To fill this gap, the present study was conducted to provide a baseline description of the gut microbiota of wild red-billed choughs (Pyrrhocorax pyrrhocorax). In this study, microbiota from four gastrointestinal locations (oropharynx, gizzard, small intestine, and large intestine) of three wild red-billed choughs were analyzed using the Illumina MiSeq sequencing platform by targeting the V4-V5 regions of the 16S rRNA genes. The gut microbiota of the red-billed choughs were dominated by the phylum Firmicutes (59.56%), followed by Proteobacteria (16.56%), Bacteroidetes (13.86%), and Actinobacteria (7.03%), which were commonly detected in avian gut ecosystems. Genus-level compositions were found to be largely dominated by Lactobacillus (18.21%), Weissella (12.37%), Erysipelatoclostridium (6.94%), Bacteroides (6.63%), Escherichia-Shigella (5.15%), Leuconostoc (4.60%), Proteus (3.33%), Carnobacterium (2.71%), Lactococcus (1.69%), and Enterococcus (1.63%). The overall intestinal microbiota was enriched with functions related to ATP-binding cassette (ABC) transporters, DNA repair and recombination proteins, purine metabolism, ribosome, transcription factors, pyrimidine metabolism, peptidases, and two-component system. In terms of four different gastrointestinal locations, hierarchical clustering analysis and principal coordinate analysis showed that microbial communities of the oropharynx, gizzard, small intestine, and large intestine formed four separated clusters. A total of 825 OTUs and 382 genera were detected in all four gastrointestinal locations, which were considered as the major microbes in the intestines of red-billed choughs. Coexistence of lactic acid bacteria and potential pathogens in the gut environments of red-billed choughs required further investigations.
