From: Age-related variation in the oral microbiome of urban Cooper’s hawks (Accipiter cooperii)
Bacterial richness in the oral cavity of individual Cooper’s hawks differed as a function of age class. Mean richness was lower in fledglings than in nestlings or adults. Results reflect data from 430 operational taxonomic units (OTU) that passed stringent quality control. Bars represent 95% confidence intervals for nestlings and adults; variation was relatively low among fledglings
