Osprey, a bird once known as a sign of revival in the United States, is now facing a severe problem in reproduction in Chesapeake Bay, Virginia. The species recovered after the pesticide DDT was banned in 1972, but new research from Bryan Watts of the Center for Conservation Biology at William & Mary showed that many pairs now raise fewer than 0.5 chicks each year. The main reason is the shortage of menhaden, a small fish that is essential for young birds. Without enough food, chicks starve, and scientists warned that the osprey population may no longer remain stable in the future.

Menhaden fishing is a business worth more than $200 million. The fish are used for oil, animal feed, and bait. Industry groups defended the practice, but environmental groups opposed the present system and called for stronger rules. Officials are now studying plans to expand quota limits and seasonal closures to protect the birds. The case highlights the struggle between business needs and nature’s survival.
