I do hope the region can focus on the A.g. geoffroyi subspecies and that some more genetically similar groups can be sourced from overseas (I guess USA or and parts of Mexico)?!Auckland Zoo have historically been one of the powerhouses of spider monkey breeding in Australasia. Their troop was founded with A. g. geoffroyi imported from the USA in 1964 and to my knowledge has remained purebred ever since.
It’s therefore my belief any spider monkeys within the region bred at Auckland Zoo are A. g. geoffroyi, including Hamilton Zoo’s entire troop, which were either bred at Auckland Zoo or born to Auckland sourced spider monkeys.
From the New Zealand Mammals thread:
Wellington originally had a mixed-species group dating from the 1960s (containing A. belzebuth, A geoffroyi and A. hybridus). Since 2009 they have obtained animals from other NZ zoos (Auckland, Hamilton, Orana) as well as importing from overseas.
Orana's colony descends from an import of five animals (2.3) from San Francisco Zoo (USA) in 1978, at the time thought to be pure A. g. vellerosus but later shown to be subspecific-hybrids. Other animals have been added more recently from other NZ zoos (e.g. Auckland and Hamilton).
(NOTA BENE: This subgroup occurs from southern Mexico, Meso-America up to Colombia, in main part of South America).
