Bacterial taxa composing the microbial signature that best differentiates among uropygial gland swabs collected during spring and fall migration based on coda4microbiome analysis. The magnitude of the coefficients represents the contribution of each variable to the model (gold = positive, green = negative). Where possible, ASVs were identified to genus, but two could only be identified to order or family (O-Enterobacteriales, F-Rhodocyclaceae)
