What is the essential care for a bird?
Pet birds (budgie, canary, parrot, cockatiel…) are sensitive animals whose needs are often underestimated. The pillars of their health: a varied, species-appropriate diet (seed mixes alone are often insufficient), a spacious cage placed away from drafts and toxic fumes, mental stimulation, and regular veterinary monitoring. Birds hide illness remarkably well: by the time signs appear, it's often already advanced. A specialized exotic / avian vet is strongly recommended.
