Study Provides First Evidence of a Relationship between a Bird’s Gut and its Brain

A study of the relationships between cognition and the gut microbiome of captive zebra finches showed that their gut microbiome characteristics were related to performance on a cognitive assay where they learned a novel foraging technique. Researchers also identified potentially critical bacteria that were relatively more abundant in birds that performed better on this assay. This correlation provides some of the first evidence of a relationship between a bird’s gut microbiome and its brain.
