Yellow cardinals are mainly solitary but are known to form pairs and even large flocks. Male yellow cardinals are extremely territorial and will attempt to drive out any other male that enters his territory.
Currently Gubernatrix cristata is listed as endangered and faces threats mainly from trapping for the pet trade and habitat loss.
