Behavioural responses are associated with mortality and mobility after reintroduction in the endangered Yellow Cardinal [PDF]
Ibis, 2023 Reintroductions are an important management tool for the conservation of threatened species. Personality or temperament of individuals is likely to influence survival in the reintroduction success of released individuals. We studied behavioural traits related to personality in the globally endangered Yellow Cardinal Gubernatrix cristata and analysed ...

Effects of fragmentation and hybridization on geographical patterns of song variation in the endangered Yellow Cardinal Gubernatrix cristata [PDF]
Ibis, 2016 The song learning process may lead to small‐scale geographical variation in vocalizations of oscine birds. This variation can be further enhanced by the effects of habitat fragmentation or hybridization. Populations of the endangered Yellow Cardinal Gubernatrix cristata are now patchily distributed in the southern South American thorny shrubland ...
