Captive‐breeding of captive and wild‐reared Gunnison sage‐grouse

Gunnison sage‐grouse ( Centrocercus minimus ) distribution in North America has decreased over historical accounts and has received federal protection under the Endangered Species Act. We investigated captive‐breeding of a captive‐flock of Gunnison sage‐grouse created from individuals reared in captivity from wild‐collected eggs we artificially incubated. We also introduced wild‐reared individuals into captivity. Our captive‐flock successfully bred and produced fertile eggs. We controlled the timing and duration of male‐female breeding interactions and facilitated a semi‐natural mating regime. Males established a strutting ground in captivity that females attended for mate selection. In 2010, we allowed females to establish eight nests, incubate, and hatch eggs. Females in captivity were more successful incubating nests than raising broods. Although there are many technical, financial, and logistic issues associated with captive‐breeding, we recommend that federal biologists and managers work collaboratively with state wildlife agencies and consider developing a captive‐flock as part of a comprehensive conservation strategy for a conservation‐reliant species like the Gunnison sage‐grouse. The progeny produced from a captive‐rearing program could assist in the recovery if innovative approaches to translocation are part of a comprehensive proactive conservation program.
