Seasonality in enteritis and gut microbiota in healthy lorikeets a Number of enteritis cases by month in Columbus Zoo and Aquarium lorikeets. Enteritis samples collected from the same bird within two weeks of the initial enteritis sample were considered a single case. Enteritis samples collected beyond 2 weeks from the initial sample in the same bird were counted as a second case of enteritis. Columbus Zoo & Aquarium healthy birds only: b Microbial community composition (Weighted UniFrac) and c diversity (Observed Features) by season (November 2018, February 2019, September 2019). There were significant shifts in microbial composition by season (PERMANOVA p = 0.001), and microbial diversity decreased significantly between November 2018 and September 2019 (Kruskal–Wallis *p < 0.001, **p < 0.0001).
