BINGHAMTON, N.Y.—A New York zoo is celebrating the arrival of two new Amur (ah-MOHR') tigers.

Koosaka and Terney arrived in Binghamton this week after a two-day trip from Billings, Mont.

The 5-year-old siblings will be featured at a zoo event next Wednesday.

The zoo had been without a tiger since losing 10-year-old Misha last August to suspected kidney disease. His brother, KJ, died in early 2011, apparently of the same ailment.

The Press & Sun-Bulletin of Binghamton ( http://tinyurl.com/cjkac6q) says Koosaka and Terney had been on loan to ZooMontana in Billings since May 2010 from the Philadelphia Zoo, where they were born. The Billings zoo lost its national accreditation last fall.

National Geographic says about 400 to 500 Amur tigers live in the wild, mostly in eastern Russia's birch forests.
