How do birds regulate seasonal expression of the migratory state? The gut hormone ghrelin could play a key role, suggests an experimental study in common quails
The seasonal expression and the migratory phenotype is signalled by rapid and marked changes in food intake, fuelling, and amount of nocturnality. We used common quails (Coturnix coturnix) to assess if the hormone corticosterone and the gut-derived hormone ghrelin play…
