Mexican citizens in the town of Otumba have honored donkeys with their own special day on the first of May, with races, rides, costumes and even a polo match.

The aim of this year’s event, which attracted thousands of spectators, was the protection and conservation of the hard-working animals, Cecilia Samiji, a government representative said.

The annual Donkey Day festival, which began about 60 years ago, is a twist on traditional May Day celebrations throughout Latin America.
