What if your life depended on finding a place you’ve never been—without GPS device, guide, or any way of knowing where to go? For young songbirds, this is the reality their first migration. While once puzzled researchers studying bird migration, advances in field have since uncovered that many songbirds rely an inherited genetic program guide remarkable solo journeys. Today, most widely accepted theory explaining how birds species migrate solitary and do not follow experienced conspecifics find wintering grounds ‘clock-and-compass’ concept. According concept, naïve migrants certain compass direction for pre-defined period. In simplest case, when runs out, they themselves species-specific non-breeding range. However, recent research suggests process might be significantly more complex. New data indicate first-time may complete map but rather system beacons.

Recent evidence indicates that green-wave surfing behaviour in ungulates and the migrations stem from this are socially learned, culturally transmitted across generations become more efficient via cumulative cultural evolution. But given a lack of corroborative evidence, whether ungulate migration is phenomenon remains hypothesis deserving further testing. In opinion piece, we summarize role memory social learning play underlies migration, when combined with natural history ungulates, argue most likely mechanism for maintenance animal culture. We our argument by providing synopsis processes promote diversification migratory link these to their emergent ecological patterns, which common nature but have not historically been considered as potential phenomena. The notion diverse portfolios may buffer populations environmental change emerges synthesis requires empirical Finally, contend that, because stems largely transmission opposed genetic programme, diversity observed strategies represents 'culturally significant units' same conservation effort afforded evolutionarily units.This article part theme issue 'Animal culture: changing world'.
