Wild Cockatoos in Sydney Unlock the Power of Social Learning

A Snack Experiment Reveals Clever Parrot Behavior

In the lush greenery of Sydney’s city parks and gardens, a group of wild cockatoos has just unlocked a fascinating survival strategy: when it comes to trying new snacks, safety in numbers isn’t just a human saying—it’s a parrot rule.

The Experiment: Blue vs. Red Almonds

Scientists conducted a bold study across five roosting spots in Sydney, presenting the parrots with a choice they’d never faced before: colored almonds—some dyed blue, others red. To the birds, these were entirely unfamiliar treats, their safety unknown.

The breakthrough came when researchers trained a few “demo” parrots at two sites to eat either the blue or red almonds. Within minutes, the rest of the flock began copying them, eagerly sampling the nuts. But the real surprise? In a third location, where no birds were pre-trained, it took days for the first daring parrot to take a bite. Yet once she did, the floodgates opened—dozens followed in quick succession.

A Community That Learns Together

Over 20 days, the study observed over 300 cockatoos across all sites embracing the colored nuts. The message was clear: these birds heavily rely on social cues to decide what’s safe to eat.

But the behavior wasn’t uniform across the flock.

• Young parrots were especially eager to mimic the majority, suggesting a strong instinct to learn from peers.
• Adult males tended to influence other males more than females, hinting at subtle social hierarchies.
• Female birds, however, were less selective, copying a wider range of companions rather than just following the dominant flock.
• Both sexes showed a keen interest in their peers’ choices, preferring to sample what others were eating rather than eating at random.

Why Does This Matter?

The findings paint a vivid picture of adaptive intelligence in urban wildlife. Just as children might choose a restaurant based on where their friends go, these parrots use social learning to navigate new food sources—a crucial skill in ever-changing city environments.

Yet researchers also noticed a subtle shift with age: while young birds are quick to follow the crowd, adults may rely less on social cues over time. Still, this strategy remains a key tool for survival, proving that even in the concrete jungle, wildlife thrives by sticking together.
