According to the Diccionario de la lengua española, in Andalusian Spanish the word collera is defined as Pareja de ciertos animales, as in Una collera de pavos ("a pair of animals, such as a pair of turkeys"). In hunting, the partners do not have to be a male and a female, although the meaning of collera is usually that of a mated pair.
