Large flock of rare swift parrots seen near Port Macquarie

A flock of about 50 critically endangered swift parrots has been spotted near Port Macquarie on Australia's New South Wales coast, offering a welcome surprise to conservationists after an unusually quiet migration season last year. Birdwatcher James Bennett was scanning the area during heavy rain when he heard the species' distinctive call, prompting him to alert fellow enthusiasts. With only an estimated 750 to 1,500 swift parrots remaining in the wild, the sighting represents a significant portion of the entire population and marks a dramatic change from 2025, when hardly any were recorded in New South Wales. Swift parrots breed in Tasmania during summer, then migrate to mainland Australia in winter to follow blooming food sources. Their movements are unpredictable, driven by the availability of specific nectar-rich blossoms and lerp—a sugary coating produced by tiny insects on eucalyptus leaves. This year's early and widespread presence across New South Wales, Sydney, and even as far north as Brisbane suggests that food sources in Victoria, where most remained last year, are less abundant. Conservation advisor Mick Roderick emphasized the importance of intact coastal forests as crucial stopover habitats for these fussy, nomadic feeders. This story offers a quiet reminder of nature's resilience and unpredictability. It highlights how migration patterns can shift year to year based on ecological conditions, and underscores the fragile balance these birds navigate. For conservationists battling habitat loss and predators like sugar gliders, the sighting is both hopeful and sobering—a glimpse of survival against steep odds, and a testament to the importance of protecting the forested corridors these brilliant, scarlet-faced travelers depend upon.

What is the 'Wason selection task' — and why it is one of the most puzzling logic problems in history

A simple puzzle involving four cards has stumped countless people for nearly six decades, revealing something profound about how humans think. Created by British psychologist Peter Wason in 1966, the Wason Selection Task presents four cards showing E, K, 4, and 7, with the instruction that if a card has a vowel on one side, it must have an even number on the other. Participants must determine which cards to flip to verify this rule—yet only about 10% get it right. The correct answer is E and 7, but most people choose E and 4 instead. The error lies in a peculiar blind spot: while people readily check what confirms the rule (E could confirm it, 4 seems relevant because it's even), they overlook what could disprove it. The card showing 7 is crucial because finding a vowel on its reverse would immediately break the rule. Meanwhile, card 4 is a red herring—the rule doesn't claim all even numbers must have vowels. Wason himself had an unconventional approach to research, preferring to design experiments first and form hypotheses afterward, letting the mind "give itself away" through unexpected results. This deceptively simple task became one of the most studied problems in the psychology of reasoning because it revealed that human logic doesn't work quite as we assumed. Wason transformed ancient philosophical intuitions about the limits of reason into something that could be experimentally observed and measured, offering a window into the systematic ways our thinking can lead us astray—even when we're certain we're being perfectly logical.
