Lineolated parakeets (linnies, barred parakeets; Bolborhynchus lineola) typically live 10–15 years (Yarmouth Veterinary Center), 15+ according to the World Parrot Trust and up to 20 according to Lafeber. There is no documented longevity record, and wild lifespan is unpublished. They mature at about 12 months.

Lineolated parakeet lifespan: how long do they live?
A pet lineolated parakeet typically lives 10–15 years, according to the Yarmouth Veterinary Center's avian care sheet, and the World Parrot Trust gives "15+ years". Lafeber says up to 20. The calculator uses the 10–15-year range, an average of 12.5 years, and counts up to 20 as the upper end for well-kept birds.
That's a long life for a bird of 42–52 g — about the weight of a large budgie — and longer than Merck's 5–10 years for budgies. Unlike most species on this site, there's no documented record to compare with: AnAge has no entry for the species, and the 2012 zoo-records study held too few linnies to say anything.

Lineolated parakeet lifespan in captivity vs the wild
Wild lineolated parakeets live in mountain forests from southern Mexico to western Panama and from north-western Venezuela and Colombia to central Peru (World Parrot Trust). They roost in large groups high in tall trees and travel in smaller groups or pairs in the dry season. The World Parrot Trust estimates 50,000–500,000 birds and lists the species as Least Concern.
Nobody has published how long linnies live in the wild, so the captive figures are all we can give. Captive birds are common in parts of Europe and less so elsewhere (World Parrot Trust), and most pets are captive-bred in many colour mutations.
Lineolated parakeet life stages and when they mature
A breeder profile from Exotic Wings gives an age of maturity of about 12 months, and an AFA Watchbird article notes that linnies take on their adult appearance after about six months. The calculator ends the juvenile stage at 1 year.
| Stage | Age | What's happening |
|---|---|---|
| Juvenile | Hatch – about 12 months | Learning, moulting into adult colours, fastest growth |
| Adult | about 12 months – 10 years | Breeding age; the long, stable middle of life |
| Senior | 10 – 15 years | Inside the typical captive range: more vet checks, easier access to food and perches |
| Beyond typical lifespan | over 15 years | A bonus; longest documented: no documented record; 'up to 20 years' (Lafeber) |
With a typical range starting at 10 years, a linnie spends most of its life as an adult. The senior stage in the calculator starts at 10 — the low end of the vet-practice range — and "beyond typical lifespan" begins after 15.
Health problems that affect lineolated parakeet lifespan
There's little published veterinary information specific to linnies. Like other small parrots, they are at risk from diet-related disease (VCA links seed-heavy diets to obesity and fatty liver), infections such as psittacosis, egg binding in hens, and the conditions Merck lists for older birds: cataracts, arthritis, kidney and heart disease and tumours. Because they are small and calm, linnies can hide illness well — weigh weekly and see an avian vet about any loss of weight, appetite or activity.
How to help your lineolated parakeet live longer
- Yearly avian-vet visits with bloodwork (PetMD); annual check-ups are also Kaytee's advice for pet parakeets.
- Pellets and vegetables first, seed as a smaller part of the diet (VCA's guidance for small parrots).
- Daily time out of the cage on a play stand or bird-safe table — linnies often prefer walking and climbing to long flights.
- Foraging and climbing toys and horizontal perches at several heights, so a linnie can walk and hang the way it likes to.
- A wide rather than tall cage, since linnies move along branches more than up and down.
Small parakeet lifespans compared
Linnies, budgies and Bourke's parakeets are all small, but their figures differ:
| Parakeet | Typical lifespan | Weight |
|---|---|---|
| Lineolated parakeet | 10–15 years (Yarmouth Veterinary Center) | 42–52 g |
| Budgie | 5–10 years (Merck) | 22–32 g |
| Bourke's parakeet | 8–13 years (Merck, grass parakeets) | 40–50 g |
On the figures available, a linnie can expect several more years than a budgie of similar weight. The evidence is thinner, though: there's no longevity record for linnies, and the vet-practice range is based on clinical experience rather than a study.
Signs your linnie is getting older
From about ten years old, watch for the age-related changes Merck lists in pet birds: cloudy eyes or misjudged hops (cataracts), stiff feet and a weaker grip (arthritis), and changes in weight. Linnies are naturally calm, so slowing down can be hard to spot; weekly weighing gives you an objective check. Lower perches, a flat resting platform and food bowls near favourite spots make life easier for an older bird, and check-ups twice a year are worth discussing with your avian vet.
Choosing a linnie
Because most pet linnies are captive-bred in colour mutations, ask the breeder about the health and age of the parents, choose a bird that is already eating pellets and vegetables, and quarantine it for 30 days before it meets other birds (PetMD).
Lineolated, linnie or barred parakeet: one species
These are all names for Bolborhynchus lineola. The World Parrot Trust lists it as the barred parakeet, with lineolated parakeet, banded parakeet and Catherine parakeet as other names; "linnie" is the affectionate short form owners use. So the barred parakeet lifespan, the linnie lifespan and the lineolated parakeet lifespan are the same 10–15 years.
The names describe the plumage: fine dark bars ("lines") across a green body. Two subspecies are recognised by the World Parrot Trust — B. l. lineola in Mexico and Central America and B. l. tigrinus in the Andes — and the species has many colour mutations, such as blue, turquoise, lutino and creamino. We found no evidence that any colour changes lifespan.
Don't confuse linnies with budgies, despite the similar size: a linnie has a short, wedge-shaped tail and a stockier build, and is a calm, quiet bird. And a linnie is not a "lined" budgie; budgies belong to a different genus from Australia.
How this lineolated parakeet lifespan calculator works
The average is 12.5 years, the middle of the 10–15-year range. A 1-year-old linnie has used about 8% of it; a 4-year-old 32%, with about 8.5 years left on average; a 10-year-old 80%, entering the senior stage. Because there's no documented record, ages beyond 20 — the highest figure any source gives — show a friendly message. No source gives a sex difference, and the care checklist changes the tips, not the numbers.
Frequently asked questions
How long do lineolated parakeets live?
Typically 10–15 years (Yarmouth Veterinary Center); the World Parrot Trust says 15+, and Lafeber up to 20.
What is a linnie's lifespan?
The same 10–15 years — "linnie" is the owners' nickname for the lineolated parakeet.
How long do barred parakeets live?
Barred parakeet is another name for the lineolated parakeet, so about 10–15 years in captivity.
What is the linnie parakeet life expectancy?
The calculator uses an average of 12.5 years. There's no documented record for the species, so up to 20 is the best upper estimate.
When is a lineolated parakeet an adult?
At about 12 months (Exotic Wings breeder profile); linnies take on the adult appearance after about 6 months (AFA Watchbird).
How long do lineolated parakeets live in the wild?
No figure has been published. The wild population is estimated at 50,000–500,000 birds (World Parrot Trust).
Do linnies live longer than budgies?
On the figures available, yes: about 10–15 years for linnies against 5–10 for budgies (Merck).
How many years does a 4-year-old linnie have left?
About 8.5 years on average, based on a 12.5-year average lifespan.
