Parrots are well-known for their outstanding cognitive ability and lengthy lifetimes.

The researchers discovered that species like the scarlet macaw and sulphur-crested cockatoo have extraordinarily lengthy average life expectancies of up to 30 years, which are generally only observed in big birds, after studying 217 parrot species.

They also discovered that big relative brain size has a probable explanation for their longevity

Longevity of parrots

The findings are the first to establish a relationship among brain size and parrot lifespan, implying that enhanced cognitive capacity may have aided parrots in navigating hazards in their surroundings and living longer lives, as per ScienceDaily.

Regardless of the fact that parrots are recognized for their full lives and complex intellect, with lifespans and relative brain sizes comparable to primates, it is uncertain if the two characteristics have affected one another.

The issue has been obtaining excellent quality data, according to Simeon Smeele, a doctorate researcher at the Max Planck Institute of Animal Behavior (MPI-AB) and principal author on the study.

According to Smeele, large sample sizes are required for comparative life-history research to give assurance since multiple processes are already at play at the same time, resulting in a lot of variance.

Researchers from MPI-AB and the Max Planck Institute for Evolutionary Anthropology (MPI-EvA) collaborated with Species360, a company that collects animal information from zoos and aquariums, to obtain a sufficient sample size.

They pooled information from over 130,000 parrots from over 1000 zoos.

The group was able to generate the first estimation of the total of parrot species with a life span length of more than 50% of all species in the world, using this information.

How being brainy relate to parrot’s longevity?

Parrots are supposed to have developed bigger brains in attempt to overcome obstacles that would have perished them otherwise, and their intelligence has helped them survive for a long time.

In contrast, other birds frequently rely on both parents, and also family and even strangers, to brood, gather, and feed the nesting female or newly hatched chicks, and occasionally also by kin and even unconnected helpers, to nurture a nest full of chicks.

In the case of parrots, several ideas may be true since they are complicated and would not have to be mutually incompatible.

Their research demonstrated a robust and positive relationship between the extent of brain volume and parrot life expectancy, as predicted.

Smeele and his colleagues then ran statistical tests on the data to see which of the three theories had the most impact on brain size.

These results bolstered the Cognitive Buffer Hypothesis’ expectation of a significant connection between larger brains and longer lives.

The researchers’ Delayed Benefits Hypothesis, as they mentioned in their paper, is likewise compatible with this result.

Because of the dietary demands of their kid’s enormous brains, primates only have one offspring.

As an outcome, birds are able to effectively nurture many large-brained chicks at the same time.

In the case of parrots, the parents are frequently pair-bonded for life, so the father recognizes the chicks as his and treats them equally.
