African Grey Parrot
Psittacus erithacus (Congo) / Psittacus timneh (Timneh)
African greys are widely regarded as among the most cognitively sophisticated parrots kept as pets, capable of contextual word use, problem-solving, and complex social learning documented in decades of avian cognition research. That intelligence is exactly what makes this species so demanding to keep well — a bored African grey is a genuinely at-risk African grey, and feather plucking, anxiety-linked behaviors, and a species-specific calcium metabolism issue (hypocalcemia) are the recurring themes across this species' health and welfare problems.
40-60 years with good care — genuinely one of the longest-lived pet birds commonly kept
13 inches, 400-490g (Congo grey); the Timneh subspecies is smaller at roughly 275-375g
Lowland rainforest of West and Central Africa, primarily the Congo Basin
Husbandry
- Minimum 24x36x48in, larger where possible, since this is a mid-to-large parrot needing genuine climbing and wing-stretching room in addition to daily out-of-cage time
- Source: Association of Avian Veterinarians (AAV) client education materials (checked 2026-03-08)
- Stable household temperature 65-80°F (18-27°C), out of drafts and away from kitchen fumes
- Source: AAV client education materials (checked 2026-03-08)
- Formulated pellets as roughly 70-80% of intake, with daily fresh vegetables and calcium-rich greens; adequate dietary calcium and vitamin D3 are especially important for this species given its documented tendency toward hypocalcemia
- Source: AAV client education materials on psittacine nutrition (checked 2026-03-08)
- Calcium supplementation should only be added under veterinary guidance following bloodwork, since both deficiency and excess carry real risks — this is not a species to supplement empirically without testing
- Source: AAV client education materials (checked 2026-03-08)
- Typically kept singly with substantial daily human interaction; African greys can be kept in compatible pairs but are also commonly strongly one-person bonded, which requires deliberate effort to prevent from becoming exclusionary

Honest disagreement among sources
Current best practice: Most avian vets recommend testing ionized calcium levels via bloodwork before supplementing, since this species' hypocalcemia risk is well documented but the correct response depends on the actual deficit found.
Noted disagreement: Some keepers, aware of this species' reputation for calcium issues, add supplements preemptively without testing; this isn't recommended, since over-supplementation carries its own health risks and doesn't address whether a specific bird's diet and sun/light exposure are already adequate.
Handling
A well-socialized African grey can be deeply affectionate and communicative, often forming an intense bond with one primary caregiver, but this species is also emotionally sensitive in a way that shows up as real behavioral fallout from inadequate stimulation, disrupted routine, or an unmet social bond — anxiety-linked feather plucking and phobic behavior (sudden, persistent fear of a previously neutral object or person) are both well documented in this species specifically.
Setting up the enclosure
A minimum 24x36x48in cage reflects that this is a mid-to-large parrot, not a large budgie — it needs genuine room to climb, stretch its wings fully, and use its feet to manipulate foraging toys, on top of daily time outside the cage in a bird-proofed space.
African greys produce a noticeably higher volume of feather dust (powder down) than many other pet parrot species, a genuine, sourced trait of this species that means more frequent cage and room cleaning, and it's worth factoring into planning for any household member with bird-dust sensitivities or asthma.
A rotating supply of foraging toys, puzzle feeders, and destructible chew items is less optional here than for most species — this bird's cognitive needs are well documented to be higher than average among parrots, and a cage without enough problem-solving enrichment reliably correlates with the behavioral problems this species is known for.
Perch diameter and material variety within the same cage matter more for this species than a single uniform perch style — offering several different diameters and textures (natural wood branches of varying thickness alongside a rope or concrete perch) supports foot health and gives the bird's feet genuine daily variation rather than repetitive pressure on the same points.
A first-time keeper setting up a cage for this species should budget for stainless steel or powder-coated bowls and hardware rather than galvanized metal, since this bird's powerful beak can access and ingest zinc from lower-quality galvanized coatings over time, a genuine and avoidable toxicity risk in a bird this capable of sustained, determined chewing.
Why the lighting and heating numbers matter
No specialized heat source is required indoors, but natural or full-spectrum light exposure supports vitamin D3 synthesis relevant to this species' calcium metabolism, which is a documented weak point compared to some other parrot species.
Wild African greys inhabit lowland rainforest across the Congo Basin, an environment with consistent year-round warmth, high humidity, and dense forest canopy filtering direct sun — captive birds do well with stable indoor temperatures and benefit from at least some regular exposure to natural daylight through a window or safe outdoor time, rather than being kept in a consistently dim interior room.
A consistent light/dark cycle (roughly 10-12 hours) supports normal sleep, and this species is documented to be sensitive to sleep disruption in ways that show up behaviorally — an African grey getting inconsistent, interrupted sleep is more prone to anxiety-linked plucking and phobic behavior than one with a stable nightly routine.
Feeding in practice
With pellets making up roughly three-quarters of the diet and fresh calcium-rich greens — collard, mustard, and other bird-safe leafy vegetables — filling out the rest daily, both general nutrition and this species' documented calcium sensitivity are covered.
Calcium and vitamin D3 adequacy matter more here than for most pet parrot species — African greys have a well-documented tendency toward hypocalcemia, and a bird on an inadequate diet with little natural light exposure is at meaningfully elevated risk, though supplementation should be guided by bloodwork rather than added empirically.
This is a highly intelligent, food-motivated species that generally transitions to a pellet-based diet without excessive resistance, and foraging-based feeding (food hidden in puzzle toys rather than presented in an open dish) both slows intake and meets this bird's strong cognitive need for problem-solving.
Common mistakes with this species
Underestimating this species' cognitive needs relative to its size is probably the single most consequential mistake — an African grey given cage space and food but insufficient daily mental engagement is at real, well-documented risk of feather plucking and other stress behaviors that a less demanding species might tolerate better.
Assuming calcium supplementation is automatically beneficial without bloodwork is a second common mistake specific to this species — the hypocalcemia reputation leads some keepers to supplement empirically, which isn't the correct response without knowing the bird's actual calcium status.
Underestimating the 40-60 year lifespan and multi-decade emotional-bonding intensity of this species is a third common gap — an African grey is a genuinely different, longer, more demanding commitment than most other parrots on this site, and it's a common candidate for rehoming later in life when this isn't fully appreciated at acquisition.
Lifespan and what to expect
A 40-60 year lifespan means an African grey acquired by an adult in their 20s or 30s may well outlive that person, and estate planning for the bird's care is a genuinely relevant, non-hypothetical consideration for this species in a way it isn't for most pets covered on this site.
Cognitive and vocal development continues over a long period, with word use and problem-solving ability typically becoming more sophisticated over the bird's first several years and continuing to develop with ongoing engagement well into adulthood.
This species is documented to form intense bonds, sometimes to a single person, and a change in that primary caregiver relationship — through rehoming, a household change, or a caregiver's reduced availability — is a recognized trigger for behavioral fallout including feather plucking and phobic behavior.
Because African greys are commonly surrendered to rescues later in life when their lifespan and behavioral needs are underestimated, adoption from a rescue with an already-known adult bird is a genuinely viable and often underused path to acquiring this species, alongside sourcing from a reputable breeder.
The Timneh subspecies, smaller and generally considered by many keepers and breeders to mature somewhat faster and show a slightly calmer temperament than the Congo grey, shares the same core husbandry needs and health considerations described here, with the main practical difference being body size.
Sexual maturity typically arrives somewhere between four and six years of age in this species, considerably later than in a small parrot like a budgerigar or cockatiel, and hormonal behavior changes — increased territoriality, nesting-seeking behavior in hens, or a shift in bonding intensity toward one household member — commonly emerge around this window for the first time even in a bird that's been calm and predictable for years beforehand.
A keeper planning around this species' realistic lifespan should also think concretely about travel, illness, or another life disruption that keeps them away from home for an extended stretch — identifying a trusted, bird-experienced backup caregiver in advance is worth doing well before it's actually needed, given how strongly this species reacts to an unfamiliar routine or an unfamiliar caregiver stepping in without any prior relationship.
Temperament in more depth
A well-socialized African grey can form a remarkably deep, communicative bond with its primary caregiver, and this species' documented cognitive sophistication means individual personality differences are often especially pronounced and easy to observe.
Phobic behavior — a sudden, persistent, seemingly irrational fear of a previously neutral object, person, or situation — is well documented in this species specifically, more so than in most other pet parrots, and it typically requires patient, gradual desensitization rather than forcing exposure to the fear trigger.
This species' emotional sensitivity means disruptions to routine, caregiver availability, or environmental stability tend to show up as real behavioral consequences (plucking, phobic reactions, withdrawal) more readily than in some hardier-tempered parrot species, which is worth planning around rather than dismissing as overreaction.

Recommended gear for African Grey Parrot
Equipment categories that are genuinely correct for this species' welfare needs — see the full Gear Guide for the complete list.
Digital infrared temperature gun
Measures actual basking SURFACE temperature, not just ambient air — a stick-on dial thermometer reads air temp, which is a poor proxy for the surface temp that drives digestion and thermoregulation.
Foraging-based enrichment (treat balls, puzzle feeders)
Foraging-based feeding meaningfully reduces stress-driven behaviors (feather plucking in birds, bar-chewing in small mammals) compared to a plain food bowl — matches the enrichment guidance referenced across the relevant species and problem pages.
Simple, easy-to-sanitize quarantine enclosure
A separate, minimal, easy-to-bleach-and-rinse enclosure (as opposed to the animal's permanent bioactive setup) makes a genuine multi-week quarantine period realistic — see the Quarantine Timeline Planner tool for recommended duration.
