Guide Brian discovers night time Costa Rican Frogs

Journey into a frog pond at night in Costa Rica with Brian, Costa Rican guide.
This was filmed in 2006 while I was spending 4 weeks at a Spanish Immersion school in Manuel Antonio, Costa Rica.

Hey guys!! There's a soft whoop-whoop-whoop sound in the background of this video, it's especially in the background when Brian is introducing himself. Anyone know what that sound is?? I've been searching for ages!!
