Spring migration frugivory may act as a quick nutrient uptake strategy for migrating passerines
Before embarking on a migratory flight, birds often exhibit extreme changes in their feeding behaviour and gut physiology, such as increased feeding, digestive organ remodelling, and shifts in diet. Many passerine species switch from insects to fruits during autumn migration,…

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…
