I hope they become founders of a breeding program in the USA and Mexico.
There may be 100s of orphaned spider monkeys kept as private pets throughout rural Mexico and 10s more in Mexican zoos. Stopping keeping monkeys as pets is not likely to be successful soon, although a worthy goal. The orphans can at least start a zoo breeding population.
Before the big confiscations in the last 1-2 years, the Mexican spider (
Ateles geoffroyi vellerosus) population was around 60-70 individuals in AZA zoos already.
North American zoos also maintain stocks of robust black spider monkeys
(Ateles fusiceps rufiventris) and central American spider monkeys (
Ateles geoffroyi geoffroyi). The blacks number about 45-50 and the Central American are the most numerous at over 100 individuals across North American zoos.
NOTE:
As for the species / subspecies under discussion: Within AZA SSP African Safari is participating in the AZA SSP for Mexican spider monkey. They actually maintain the largest breeding population of Mexican spider monkeys within the AZA program, but it seems no exchanges with US zoos have occured.
I am sure there should be other zoos in Mexico holding the Mexican spider monkey subspecies (
Ateles geoffroyi vellerosus). I hope some of our Mexican or Latino American Zoochat friends may have further information.
Brownsville Zoo actually maintains both Mexican (2.4.2 individuals with active breeding - don't really know why given their wild status???) and robust black (1.2.2 individuals). Abilene Zoo also held 2.2 mid range aged Mexican (non-breeding and now seems to have received both 0.2 youngster confiscated by USFWS in Houston and 2.0 additions from Brownsville. I suspect Abilene will in future start breeding from these youngsters.
Suffice to say the illegal trade in spider monkeys from Mexico is rampant ATM and a real CITES / animal trade issue now for both SW Texas and New Mexico (?) plus Arizona (?). I would applaud closer cooperation between both the US and Mexican country Ministry of the Environment/Agriculture authorities, national nature conservation authorities, in situ conservation NGO's and ex situ conservation breeding community (both US, Mexico and some northern Meso American states like Guatemala and Honduras).
