The Dodo, a famous flightless bird from Mauritius, went extinct due to human activities after Dutch sailors found it in 1598. In less than 80 years, hunting, habitat loss, and the introduction of new species led to its disappearance. Sadly, this is not an isolated case. A recent study reveals that 610 bird species have gone extinct over the past 130,000 years, closely linked to human expansion. For example, the Hawaiian songbird Kauaʻi ʻōʻō (pronounced Kah-wah-‘ee ‘Oh-‘Oh) was declared extinct last year. The loss of bird species harms ecosystems because birds help by spreading seeds, controlling insects, and pollinating plants. According to ecologist Tom Matthews from the University of Birmingham, many fruit-eating birds are now extinct on islands like Mauritius and Hawaii. This has reduced tree species that depend on birds for seed dispersal. Invasive animals, such as rats and cats, have also contributed to bird extinction, especially on islands where birds had no natural predators. Unfortunately, over 1,000 bird species could become extinct in the next 200 years due to human actions.
