Bird behavior
Hormonal behavior is normal biology, but the home routine can make it easier or harder.
Seasonal aggression, nesting, regurgitation, clinginess, egg laying, and guarding favorite spaces need calm management, not punishment or constant petting.

Watch for nesting in dark spaces, shredding with a purpose, regurgitation, crouching, tail lifting, sudden guarding, favorite-person intensity, or new aggression around cages and toys.
Dark boxes, fabric huts, drawers, under-furniture spaces, paper piles, and cozy enclosed areas can push some birds toward nesting behavior. Keep enrichment open and easy to inspect.
For many parrots, stroking the back, wings, tail base, or belly can be sexual stimulation. Keep affection friendly and brief, then redirect to training or play.
Long bright evenings, irregular sleep, and high household excitement can make seasonal behavior harder. A predictable dark, quiet sleep period helps many birds stay steadier.
Too many rich treats, warm soft foods, constant access to one favorite person, or endless shoulder time can feed the pattern. Use measured treats and reward calm independence.
Repeated egg laying, straining, fluffed posture, weakness, appetite change, or major behavior changes deserve avian-vet help. Do not try to solve possible reproductive or health problems with training alone.
Use supplies as structure, not shortcuts. The goal is to make calm choices easier for the bird.
