Title: Genetics of Migration in willow warblers

Abstract: Right before northern hemisphere’s summer shifts to autumn, small insect-eating birds start lengthy journeys to tropical regions. It’s been known for a long time that a substantial part of this behavior is genetically controlled however the genetic basis of bird migration remains poorly understood. We tracked genotyped willow warblers Phylloscopus trochilus from a migratory divide in Sweden where south-east and south-west migratory subspecies meet and interbreed. We found that two markers that seem to follow dominant inheritance and interact epistatically together explain 74% of variation in migration direction. The talk will be based on our recent paper: https://doi.org/10.1038/s41467-023-35788-7
