- •
Many predators are precocial, but few studies have compared juveniles to adults.
- •
We quantified key predatory behaviors of both juvenile and adult sidewinders.
- •
For the most part, juveniles are as effective as adults at hunting and subduing prey.
- •
Adult snakes may be better at locating profitable hunting sites.
- •
These findings provide important baseline data for future empirical research.
