A zoo in China has built observation decks so that employees can watch animals including chickens, pigs, and fish to see if they can accurately predict earthquakes.
According to one English-language Chinese news outlet, "At Banqiao ecological park... the behavior of around 200 pigs, 2,000 chickens, and fish in a 15-hectare pond are closely monitored to detect signals of an earthquake. Breeders here create daily reports regarding animal behavior for Nanjing's seismological departments." The news report noted that the park relies "mainly on employees closely watching the animals" for seismological significance.
Despite a few predictably sensationalized headlines about "psychic animals," there's no need to attribute any sort of ESP or psychic ability to possible animal earthquake detection.

The belief that animals can detect earthquakes (as well as resulting tsunamis) is an old one, and has some scientific validity to it. The fact that animals have keener senses than humans is well-documented. Dogs have a remarkable sense of smell, birds can migrate using celestial cues, and bats can locate food with echoes. Elephants can detect faint vibrations and tremors (such as other elephants' footsteps) from fantastic distances.
