Research overview: the nomadic phase in male lion life history

Before they can win a pride, young male lions endure a nomadic phase after being evicted from their natal range. This overview synthesizes what is known about this risky period: bachelors roam widely, scavenge and hunt opportunistically, form or strengthen coalitions, and avoid established territory holders until they are strong enough to challenge them. It reviews mortality during nomadism, the importance of coalition partners for survival and eventual takeover, and how the duration of the nomadic phase shapes lifetime reproductive success. The synthesis frames male life history as a gamble in which only those that survive to seize and hold a pride reproduce. For observers it explains the appearance of wandering young males at the edges of prides and the tension that precedes a takeover.
