Macaws are the largest parrots in the world and among the most demanding pet birds you can keep. Our pet bird care guides cover the full range of species, but macaws sit at the top for complexity, cost, and commitment.
We're not going to oversell this. Macaws are extraordinary birds.
They are also a 30–80 year commitment that will outlive most furniture in your house and possibly you.
Macaw Species: 6 Common Pet Species and Their Size Differences
Not all macaws are the same size, volume, or temperament. The species you choose shapes every aspect of keeping, from cage dimensions to noise tolerance requirements in your neighborhood.

- Blue and Gold Macaw: 33–34 inches, 2–2.6 lbs, most beginner-friendly of the large species, reliable talker
- Scarlet Macaw: 32 inches, 2 lbs, visually stunning but more demanding, less tolerant of inconsistency
- Green-winged Macaw: 35–40 inches, 2.5–3.7 lbs, the largest common pet macaw, gentler temperament than Scarlet
- Hyacinth Macaw: 40 inches, 2.6–3.7 lbs, the largest macaw species, extraordinarily expensive ($10,000–$20,000)
- Hahn's Macaw: 12 inches, 0.3 lbs, smallest pet macaw, apartment-viable, quieter than full-size species
- Severe Macaw: 18–20 inches, 0.9 lbs, mini-macaw with full-size personality, excellent talker
For first-time macaw keepers, the Blue and Gold is the standard recommendation. It's the most studied, the most commonly bred, and has the most temperament consistency across individuals.
African greys and macaws are often compared as the two pinnacles of large parrot keeping, and our african grey parrot guide outlines where the two species diverge in care.

Macaw Housing: Why 3×3×5 Ft Is the Starting Point, Not the Goal
The minimum cage for a large macaw is 3 feet wide × 3 feet deep × 5 feet tall. That's a cage most keepers underestimate until they stand next to one in a store.
Bar spacing matters as much as dimensions. Large macaws need bars spaced 1 to 1.5 inches apart.
Too close and the bird can't grip comfortably. Too wide and it gets a foot or head trapped.
Cage material must be powder-coated wrought iron or stainless steel. Zinc and lead-based paints are toxic.
- Perch diameter: 1–1.5 inches for large macaws, varied textures to prevent foot problems
- Perch material: Natural wood (manzanita, Java wood) preferred over uniform dowel rods
- Toy rotation: 3–5 active toys at all times, swap weekly to prevent boredom
- Cage placement: Against a wall (not corner), eye level, away from kitchen fumes and drafts
Macaws require 4+ hours out of cage daily. This is not optional enrichment.
A macaw confined all day develops feather-destructive behavior, aggression, and repetitive stereotypies that are extremely difficult to reverse.
Cockatoos share the macaw's emotional intensity and similar space requirements, so reading our cockatoo care guide helps you weigh both options before purchasing.
Sunflower seeds are used as training rewards for macaws and our sunflower seed quantity limits guide covers how many to offer before fat-related health problems develop.
Macaw Diet: The 60/30/10 Rule for Long-Term Health
Seed-only diets kill macaws slowly. Seeds are high in fat and deficient in the vitamins, minerals, and amino acids macaws need for organ and feather health.
A macaw eating only seeds will look dull and live shorter than its potential.
The working macaw diet is 60–70% high-quality pellets, 20–30% fresh produce, and 10% or less in nuts, seeds, and treats.
- Pellets: Harrison's Bird Foods, Zupreem Natural, or Roudybush, one of these as the base
- Vegetables: Dark leafy greens (kale, chard, romaine), bell peppers, squash, carrots daily
- Fruits: Berries, mango, papaya, apple (no seeds), melon, limit to 10–15% of produce
- Nuts: Almonds, walnuts, Brazil nuts for training rewards, 2–4 per day maximum
- Grains: Cooked brown rice, quinoa, whole wheat pasta as occasional additions
Feed fresh produce in the morning and early afternoon. Remove uneaten fresh food after 4 hours.
Never feed avocado (persin toxicity), chocolate, caffeine, alcohol, onions, garlic, or any seasoned food.
Mini macaws overlap in size with the larger conures, and keepers unsure which to choose should review our conure care guide for a lower-commitment alternative.
Blue-and-gold macaws are among the strongest talkers in the large parrot category, earning a featured spot in our best talking birds guide.
Macaw Health: 4 Common Conditions and Their Early Signs
Macaws are generally robust when kept correctly, but several conditions appear consistently across the species. Catching them early is the difference between a manageable vet visit and a crisis.
Annual wellness exams with an avian-certified veterinarian are not optional at this commitment level. Find one before you bring the bird home, not after it gets sick.
Macaws accept most fruits readily and banana is a soft, easy option confirmed safe for large parrots in our banana feeding frequency guide.
Macaws are explicitly not a beginner bird, a point our best birds for beginners guide makes clearly when steering new keepers toward smaller species.
- Psittacosis (Chlamydiosis): bacterial infection causing lethargy, nasal discharge, green droppings, treatable with doxycycline if caught early
- Proventricular Dilatation Disease (PDD): viral GI condition, progressive weight loss despite normal appetite, no cure, managed palliatively
- Feather Destructive Behavior (FDB): over-preening to self-mutilation, usually behavioral (boredom/stress) but sometimes medical, requires full workup
- Aspergillosis: fungal respiratory infection from damp or moldy environments, causes wheezing and open-mouth breathing, antifungal treatment required
Macaw Training: How Operant Conditioning Works for Parrots
Macaws are highly intelligent and respond well to positive reinforcement training. The method that works is simple: reward desired behavior immediately with something the bird values (usually a small nut or piece of fruit), ignore or redirect unwanted behavior.
Punishment does not work with macaws. It destroys trust, creates fear-based aggression, and produces a bird that bites defensively rather than a bird that cooperates willingly.
Step-up training is the foundation: teach the bird to step onto your hand on cue, and nearly every other behavior becomes buildable from there.
Apple is a reliable daily fresh food for macaws and our apple preparation requirements guide confirms the seed-removal step before serving.
Whole grapes make good foraging enrichment for macaws and our grape enrichment safety guide confirms they are appropriate in moderate amounts.
Macaw Lifespan and Long-Term Commitment
Blue and Gold macaws average 50–60 years in captivity with proper care. Hyacinth macaws can reach 80.
This is not a figure of speech. The bird you bring home as a companion will likely need care arrangements in your estate planning.
Most macaws rehomed to sanctuaries and rescues come from keepers who didn't fully understand this timeline. The bird bonded to one person, that person's life changed, and the bird spent its remaining decades cycling through inadequate homes.
Account for this before purchase.
