Wisdom – USFWS / SWNSThe world’s oldest known bird has returned to her home island to hatch yet another chick, at nearly 74 years old.Named Wisdom, the Laysan albatross has been spotted this month caring for her youngster on Midway Atoll National Wildlife Refuge in the Pacific Ocean.Like others of her species, Wisdom returns to the same nesting site each year to reunite with her mate and if able, lay one egg.For decades, park officials in the Hawaiian Archipelago observed Wisdom doing this with the same partner (named Akeakamai), but that bird has not been seen for several years, which caused Wisdom to begin courtship dances with other males last year.The spry septuagenarian is estimated to have produced 50-60 eggs in her lifetime, successfully fledging as many as 30 chicks, according to the expert staff at the refuge 1,300 miles northwest of Honolulu.Albatross parents share the responsibility of feeding their young by taking turns hunting while the other stays at the nest to watch over the chick.“So when Wisdom returns to the nest (it’s) her partner’s turn to go hunt for squid, fish and crustaceans,” said a statement from the U.S. Fish and Wildlife Service–Pacific Region.Biologists first identified and banded Wisdom in 1956 after she laid an egg. They determined her estimated age from that event 69 years ago, because the large...
World’s Oldest Bird Gives Birth to Yet Another Chick–at Nearly 74 Years Old
Countries Are Breathing the Cleanest Air in Centuries and Offer Lessons to the Rest of Us
An article at Our World in Data recently explored trends in air quality across a selection of high and middle-income countries, and found that not only is the West breathing better air than at perhaps any point since urbanization, but that developing nations likely won’t need 100 years or more to arrive at similar outcomes.Published by Hannah Ritchie, the article focuses on two kinds of gases emitted from industrial activity: sulfur dioxide (SO2) and nitrogen oxide (NOx). Both enter the air we breathe from the burning of fossil fuels—coal in particular—while the latter is emitted mostly from internal combustion engines.Bad air quality is responsible for millions of lost life years worldwide from respiratory problems, cardiovascular issues, and neurological disease—all of which can develop and become exasperated under prolonged exposure to air pollutants.UK sulphur dioxide emissions – credit Community Emissions Data System (CEDS) 2024, CC BY license.As seen in this chart, emissions of SO2 have just dipped under levels seen at the earliest periods of British industrialization. Before this, city and town air quality would have been badly tainted through emissions of wood smoke, so it’s safe to assume that 2022 marked the best British air in many centuries, not just the last two.SO2 enters the ambient air primarily in urban environments...
