Captive breeding is increasingly being used to create supplies of endangered animals for release into natural habitats, but rearing strategies vary and debates arise over which methods are most efficient. We assessed postrelease behaviors and survival of three groups of black-footed ferrets, each with different prerelease experience. Eighteen ferret kits â‰¤60 days of age were moved with their dams from cages to 80-m2 outdoor pens with prairie dog burrows. These animals were compared to animals reared in standard cages (n=72), some of which were given experience killing prairie dogs (n=32). Ferrets were released onto white-tailed prairie dog (Cynomys leucurus) colonies in Wyoming, USA, in fall, 1992. Radio-tagged...

Hawaii Island locations of reintroduced Alala from automated radio telemetry tracking system, 2017 cohort
Alala, or Hawaiian Crow (Corvus hawaiiensis), were extinct in the wild since the early 2000s. The first effort to reintroduce captive bred Alala back into the wild was conducted at Puu Makaala Natural Area Reserve on Hawaii Island. The 2017 release cohort were released in two stages and were the only Alala in the wild. Using automated radio telemetry tracking towers (n=4) that were distributed around the release area, we tracked the birds from September 26, 2017, to May 19, 2018, to document early exploratory movement of these birds in the wild.
This study addressed the initial effects of a reintroduction of Gunnison's prairie dogs (Cynomys gunnisoni) on resident small mammal and plant communities on the Sevilleta National Wildlife Refuge (SNWR), New Mexico. In spring 1997, 60 prairie dogs (36.8 kg live mass) were introduced onto a former prairie dog colony in a desert grassland site. Small mammals and vegetation were sampled on both a treatment (reintroduction site) and a control site (without prairie dogs) before and after the prairie dogs were reintroduced. We tested for differences in small mammal and plant community change during the 1st year of the colony's existence using repeated measures analysis of variance. Although prairie dog biomass was ca....
