In at least one area they do this at intersections, so they can safely walk out and collect their cracked prizes when the light turns red and the cars stop. Crows have in some locales learned to drop nuts on the road for cars to crack. In some places, pigeons and sparrows have learned to use motion-sensors to get inside enclosed shopping malls and forage for crumbs. Culture enables adaptation far faster than genes alone can navigate hairpin turns in time. Landscapes, always complex, are under accelerated change. Conservation workers could not teach the captive-raised parrots to search for and find their traditional wild foods, skills they would have learned from parents.

“In a cage,” Williams says, “you can’t train them to know where, when and how to find that food, or about trees with good nest sites.” Parents would normally have done exactly that.Ī generational break in cultural traditions hampered attempts to reintroduce thick-billed parrots to parts of south-west America, where they’d been wiped out. Trying to restore parrot populations by captive breeding is not as easy as training young or orphaned creatures to recognise what is food while they’re in the safety of a cage – then simply opening the door. Survival of released individuals is severely undermined if there are no free-living elder role models. Many young birds learn much by observing their parents, and parrots probably need to learn more than most. Recovery of lost populations then becomes much more difficult than bringing in a few individuals and turning them loose.Įcologist and writer Carl Safina. Long before a population declines to numbers low enough to seem threatened with extinction, their special cultural knowledge, earned and passed down over long generations, begins disappearing. Yet for many species culture is both crucial and fragile. Until now, culture has remained a largely hidden, unrecognised layer of wild lives.
We are just recognising that in many species, survival skills must be learned from elders who learned from their elders. Culture in the other-than-human world has been almost entirely missed. In the human family many cultures, underappreciated, have been lost. Crucially, culturally learned skills vary from place to place. Socially learned skills, traditions and dialects that answer the question of “how we live here” are crucial to helping many populations survive – or recover. Culture is knowledge and skills that flow socially from individual to individual and generation to generation.
