Captive Breeding and Raising of Prairie-Chickens for Release into the Wild, with Experimental Methodologies Potentially Applicable for Breeding Other Galliformes
One million Attwater’s prairie-chickens (APC; Tympanuchus cupido attwateri) historically occupied coastal plains of southern Texas and Louisiana. Wild birds exist primarily at the Attwater Prairie Chicken National Wildlife Refuge and vary from 40-200 birds depending on time of year. This bird survives through captive breeding by wildlife parks and zoos, and annual releases of offspring, but significant wild population growth has not yet been attained. One obstacle has been red imported fire ants that impact insect communities on which APC chicks feed. Another obstacle is climate, with Hurricane Harvey severely impacting the recovery efforts in 2017. Overall, propagation of captive Galliformes has proved complicated and difficult, and production of birds that show high survival and significant reproduction in the wild is a challenge. Utilizing original and novel methods for breeding and managing captive galliformes, the Sutton Avian Research Center is experimenting with techniques at a dedicated facility in Oklahoma. Greater prairie-chickens (GPC) serve as surrogates initially to test efficacy of prospective designs and methodology. Experimental methods include: 1) natural breeding in pairs and trios; 2) female mate choice among separated males; 3) efforts toward breeding imprinted birds for artificial insemination; 4) establishment of outdoor captive booming grounds offering female mate choice and nesting areas; 5) release of Sutton bred birds in areas where the captive hatched GPC can mingle with wild “mentors.” Other techniques tested include use of natural food like clover, dandelions, insects, and wild grouse “gut flora.”
