The gut microbiome shapes and is shaped by a host animal’s physiology. Avian taxa hold physiological characteristics unique from mammals and might inform novel pressures experienced by microbial communities. Further, the symbionts’ relative abundance and their abilities to adapt to available resources are of critical importance to a holobiont’s fitness in rapidly changing climates. Therefore, wild populations of hummingbirds Selasphorus rufus and Calypte anna were studied. The two systems differ in S. rufus’s annual migrations from wintering grounds to their breeding grounds in the Pacific Northwest, whereas C. anna are resident in the latter region. Previous findings have indicated …
