Male is a bully
I have two budgies, one male and one female. The male seems to be a “stalker” to the female, as if he’s in adoration with her, but when it comes to food and treats, he almost pushes her away, wanting it all or himself. (I always put celery, carrots, apples, etc. out for them). As much as he seems to “love” her, he seems to not want her to eat. Note: my birds are “free” in my office at home. They have two open cages, many toys and perches and they can fly free around the room.
