This study evaluated the effectiveness of environmental enrichment methods and the haloperidol administration in controlling feather picking in parakeets kept in captivity. Three groups were formed: G1 haloperidol treatment, G2 subjected to environmental enrichment and G3 no feather picked parakeets. In the behavioral study was used scan, instant registration: before, during and after the treatments. The plumage evaluation was done following a score from 0 to 10. G1 parakeets reduced significantly the activity, increasing stopped time on the perch and also reduced their expression of other behaviors. No G1 birds improved the plumage quality, already only one G2 parakeet has not improved feather condition. Thus, the use of environmental enrichment promotes better animal welfare conditions and provided the growth of new feather in the picked areas, in contrast to the observations made in psychogenic feathers picked parakeet treated with haloperidol
