Binghamton Zoo at Ross Park’s Amur tiger sisters, Koosaka and Terney, will be moving to the Philadelphia Zoo and the Pittsburgh Zoo and PPG Aquarium for breeding purposes on November 17, 2015.

Koosaka and Terney were born in the same litter at the Philadelphia Zoo in 2007 and then moved to Zoo Montana in 2010. They came to the Binghamton Zoo at Ross Park in 2012 where they have resided in the Great Cats of Asia exhibit. Now at 8 years old, they are considered to be important to the North American population and can be paired for breeding.

The Amur tiger Species Survival Plan (SSP) recommended the relocation of the tigers based on their genetic importance. Through the Association of Zoos and Aquariums, SSP’s work to manage captive animal populations so that genetic diversity and population growth are maintained. SSP’s also play an active role in the global conservation of each species they represent.

The Binghamton Zoo at Ross Park eagerly works with more than 15 SSP’s, including snow leopard, red panda and Andean bear. Most recently, based on the breeding recommendation from the prehensile-tailed porcupine SSP, a female porcupine was born to our collection this past June.

Visitors are encouraged to visit Koosaka and Terney at the zoo on November weekends leading up to their departure. Admission gates are open 10:00 am – 3:00 pm every Saturday and Sunday through November 29th. Visit us online at for events and promotions.

Binghamton Zoo at Ross Park staff will announce plans for the exhibit at a later date. The plan will align with the mission and already established master plan of America’s 5th Zoo.

The Binghamton Zoo is located at 60 Morgan Road in Binghamton, NY. For information, call (607) 724-5461 or visit the zoo website at
