“…relative small brain size, foraging style that does not required extensive food handling) that were found to be linked to a lower likelihood to develop feather damaging behaviour and stereotypies when kept as companion animals 65 . Nevertheless, even if these seven species are perceived as more suitable companions, all of them, budgerigars 80,81,86,87 , cockatiels [88][89][90][91] , conures 67 , lovebirds 63,67 , pacific parrotlets (Forpus coelestis) 67 and monk parakeets 6 , can show signs of poor welfare when kept in inappropriate conditions. As the results regarding specific species' suitability as a companion animal were not processed in multiple rounds, further research should be performed to validate these findings, and evaluate in further detail whether and which biological characteristics would render a species more or less adaptable to the domestic environment.…”
