Zoo to open breeding facility for endangered greater sage grouse

The Calgary Zoo says it has opened the first breeding facility in Canada for one of the country’s most endangered birds. The zoo says estimates put the number of greater sage grouse in Canada between 250 and 350, although some have put that number as low as 140. The zoo has had a breeding program for two years and currently has 18 sage grouse. The goal is to build a sustainable captive population that will one day bolster the birds in the wild.
