The birds are captive bred (the birds have not been caught in the wild and have been born and bred in captivity from parents that mated or had gametes otherwise transferred in captivity).
Linnud on kasvanud vangistuses (need ei ole püütud loodusest, vaid on sündinud vanematest, kes on vangistuses paaritunud või muul viisil sugurakke üle kandnud).
