How Long Do Ravens Live?
[science] Common Ravens typically live 10–15 years in the wild. The confirmed wild maximum from banding studies is at least 23 years. In captivity, ravens can live considerably longer — into their 30s and 40s. Mortality is highest in the first year of life; birds that reach adulthood have a reasonable chance of living 10+ years.
Wild Lifespan — the Evidence
[science] Raven lifespan data comes primarily from banding (ringing) studies in North America and Europe, where individual birds are marked and monitored over many years. The Birds of the World account for Common Raven (Boarman & Heinrich, 1999) summarises the available data: typical adult annual survival is 72–87%, which projects to a mean lifespan of roughly 10–15 years for birds surviving their first year.1
The maximum recorded wild age from banding data cited in that account is 21–23 years for individual birds in Europe. Wild maximum life expectancy is not the same as average life expectancy — most wild ravens die from accidents, starvation, disease, or predation well before reaching their theoretical maximum.
First-Year Survival — the Critical Period
[science] The first year is by far the most dangerous for ravens. Young ravens that have recently left the nest lack the food-finding skills, territory, and social knowledge of adults. Estimates of first-year survival in wild Common Ravens range from 20–50% depending on the population and habitat — meaning the majority of ravens born in a given year do not survive to adulthood.1
Ravens that survive to their second year, establish a territory, and find a mate have a much higher annual survival rate and can reasonably be expected to live a decade or more.
Captive Lifespan
[science] In captivity, free from predation, starvation, and many diseases, ravens can live significantly longer. Zoo records and accounts from long-term captive holders (including the Tower of London) suggest individual birds may reach 30–44 years, though the highest figures are from institutional records rather than peer-reviewed studies and should be treated with some caution.2
As a comparison: the maximum captive longevity for Common Ravens listed in the Handbook of the Birds of the World is 29 years, with some individual reports extending beyond this.
It Depends On…
- Habitat: Ravens in stable, food-rich territories live longer than those in marginal habitats where winter mortality is high.
- Pair status: Paired adults with established territories have higher survival rates than unpaired floaters in non-breeding flocks.
- Human pressure: Where ravens are still persecuted (shot or poisoned, legally or illegally), lifespans are shorter. Legal protection in the UK and much of Europe has allowed ravens to reach older ages.

Frequently Asked Questions
What is the oldest raven ever recorded?
The oldest reliably documented wild Common Raven was at least 23 years old, based on ringing (banding) data from a European study. In captivity, ravens have lived into their 40s; the Tower of London ravens are reported to have reached 44 years, though individual records for captive birds are not always rigorously documented.
How long do Tower of London ravens live?
The Tower of London's ravens are captive birds. Tower records claim individual birds have lived into their 20s and beyond; one bird ("Jim Crow") is reported to have reached 44 years. These are institutional records, not independently verified scientific data.
Do ravens live longer than crows?
Yes, in general. American Crows typically live 7–8 years in the wild (maximum about 14 years, banding records). Common Ravens average 10–15 years in the wild with potential to exceed 20 years. The pattern — larger corvids live longer — is consistent with the broader relationship between body size and lifespan in birds.
