Why do young owls in the same nest hatch at different times?

Owls typically lay their eggs at two-day intervals, and because hatching is not synchronized, the young in a single nest hatch at different times. This results in a significant age gap, where the oldest and youngest nestlings in a large brood may be born two or three weeks apart.1

This asynchronous hatching serves as a survival strategy related to food availability. If prey populations are insufficient to support the entire brood, the younger, smaller nestlings may starve, while the more aggressive, older nestlings are able to maintain normal growth rates and remain strong enough to fledge.1
