Volunteering without having to pay?

---

i'm down in costa rica actually on the nicoya peninsula. i was going to volunteer at rainsong wildlife sanctuary, but it was awful, disorganized, and scary. i'm here for a few weeks and was looking for new volunteering opportunities that are actually volunteering (and not having to pay to work for free).

does anyone have any ideas or websites i can take a look at? i'm open to volunteer work in almost any part of the country, but i prefer it to be volunteer work with animals. or if anyone has any suggestions of what i can do for the next few weeks on a slim to nil budget (since i planned on volunteering and not spending a whole lot of money).

i can pay for my own accomodations and food, but suggestions for cheap programs including meals and/or accomodations are welcome

thanks a ton for any help i can get!
