I've had people question if they get jealous for my attention in the past and as you can see it does happen. It happens more so with Rukus and Mardi being that they are my "velcro" birds. Rukus thinks he is deserving of all my scritches/petting and Mardi more so over kisses. Lately they tend to lash out at Dunkin because he is a kissing machine and he is currently going through a molt and I'm helping him along. The all get plenty of daily interaction but sometimes this may happen. Neither myself nor any birds were harmed.
