Wild horses gallop in a plowed area of Amajari in the Amazon city of Boa Vista in the state of Roraima, Brazil, December 2, 2015. The wild horses, known as "Lavradeiro horses" and introduced by colonists, were brought from Portugal, Spain, North Africa and Cape Verde, and are therefore purebred descendants of the Arabian Barbo and Andalusian breeds, according to the INCT (National Science and Technology Institutes Brazil). The original animals escaped from farms and now number around 1,500 horses n the region, according to EMBRAPA (Brazilian Agricultural Research Corporation). Picture taken December 2, 2015.
