A major UCLA study says that at least 65 species of animals laugh

Foxes giggle like children on helium.

Laughter is one of the most natural impulses in humans. Most babies start to laugh out loud at around 3 to 4 months, far earlier than they are able to speak or walk. Expressing enjoyment or delight comes naturally to us, but we're not the only creatures who communicate with giggles.

Researchers at UCLA have identified 65 species of animals who make "play vocalizations," or what we would consider laughter. Some of those vocalizations were already well documented—we've known for a while that apes and rats laugh—but others may come as a surprise. Along with a long list of primate species, domestic cows and dogs, foxes, seals, mongooses and three bird species are prone to laughter as well. (Many bird species can mimic human laughter, but that's not the same as making their own play vocalizations.)

Primatologist and UCLA anthropology graduate student Sasha Winkler and UCLA professor of communication Greg Bryant shared their findings in an article in the journal Bioacoustics.

The authors explored various play vocalization sounds, recording them as noisy or tonal, loud or quiet, high- or low-pitched, short or long, a single call or rhythmic pattern.
