# Preying
When you reach level 21, your egg will hatch into a bird—awesome, right? Now your bird can prey twice a day for plenty of $BIRDS and WORMS!
**How to prey?**
\
Step 1. Click on **"Prey"** icon in the home page
\
Step 2. **Feed** worms to your Bird
Your Bird need at least 50% energy to begin preying. Use maximum energy for maximum profit
Step 3. Click on **"Start prey"**
The preying time is 12 hours, after which you can claim your rewards ($BIRDS and Worms).
Step 4. Click on **"Claim rewards"**
The higher your level, the greater the rewards you can earn from preying.
***Note: Feeding worms, starting prey, and claiming rewards are on-chain activities in the game, so you need to have SUI in your wallet to approve transactions.***
**Massive rewards:** You’ll earn a 3% bonus each time your Bird's friend preys. Don’t forget to invite your friends to join the fun and play Bird together!
**Energy and $BIRDS rewards for each level when Bird Preying.**
