We've seen a lot of videos out there with people making silly noises at llamas, and claiming that those silly noises are an effective way to attract llamas. Great, press play and the llama just stands there, or spits at the person making the noise.
This video does not show llamas being antagonized or spitting, just love.
This short video demonstrates a working llama call that actually drives the beautiful llama to a crazy level of attraction that it runs and charges us. When it finally reaches us, it offers lots of loving affection (no llama spitting). At the end of the clip you can clearly see that this friendly llama ran so hard that he was out of breath! Maybe try using this call with your local llama, and check back for more llama calls that actually work!
Update: we learned recently that this llama's name is Larry. Larry the llama!
