GLOUCESTER POINT, Va. (AP) 鈥� Stepping onto an old wooden duck blind in the middle of the York River, Bryan Watts looks down at a circle of sticks and pine cones on the weathered, guano-spattered platform. It鈥檚 a failed osprey nest, taken over by diving terns.

鈥淭he birds never laid here this year,鈥� said Watts, near the mouth of Virginia鈥檚 Chesapeake Bay. 鈥淎nd that’s a pattern we’ve been seeing these last couple of years.鈥�

Watts has a more intimate relationship with ospreys than most people have with a bird 鈥� he has climbed to their nests to free them from plastic bags, fed them by hand and monitored their eggs with telescopic mirrors.

The fish-eating raptor known for gymnastic dives and whistle-like chirps is an American conservation success story. After pesticides and other hazards nearly eliminated the species from much of the country, the hawk-like bird rebounded after the banning of DDT in 1972 and now numbers in the thousands in the U.S.

But Watts has documented an alarming trend. The birds, which breed in many parts of the U.S., are failing to successfully fledge enough chicks around their key population center of the Chesapeake Bay. The longtime biologist blames the decline of menhaden, a small schooling fish critical to the osprey diet. Without menhaden to eat, chicks are starving and dying in nests, Watts said.

Osprey are an environmental indicator

Watts’s claim has put him and environmental groups at odds with the fishing industry, trade unions and sometimes government regulators. Menhaden is valuable for fish oil, fish meal and agricultural food as well as bait.

U.S. fishermen have caught at least 1.1 billion pounds of menhaden every year since 1951. Members of the industry tout its sustainability and said the decline in osprey may have nothing to do with fishing.

But without help, the osprey population could tumble to levels not seen since the dark days of DDT, said Watts, director of the Center for Conservation Biology at The College of William & Mary in Williamsburg, Virginia.

鈥淭he osprey are yelling pretty loudly that, hey, there’s not enough menhaden for us to reproduce successfully,鈥� Watts said. 鈥淎nd we should be listening to them to be more informed fully on the fisheries side, and we should take precaution on the fisheries management side. But that hasn’t won the day at this point.鈥�

Decline linked to menhaden in studies

Watts, who has studied osprey on the Chesapeake for decades, has backed his claims of population decline by publishing studies in scientific . He said it boils down to a simple statistic 鈥� to maintain population, osprey pairs need to average 1.15 chicks per year.

Osprey were reproducing at that level in the 1980s, but today in some areas around the main stem of the Chesapeake, it’s less than half of that, Watts said. In particularly distressed areas, they aren’t even reproducing at one-tenth that level, he said. And the decline in available menhaden matches the areas of nesting failure, Watts said.

Also called pogies or bunkers, the oily menhaden are especially important for young birds because they are more nutritious than other fish in the sea. Osprey 鈥渞eproductive performance is inextricably linked to the availability and abundance鈥� of menhaden, published in Frontiers in Marine Science.

Conservationists have been concerned for years, saying too many menhaden have been removed to maintain their crucial role in the ocean food chain. Historian H. Bruce Franklin went so far as to title his 2007 book on menhaden 鈥淭he Most Important Fish In The Sea.鈥�

Fishing industry pushes back

Menhaden help sustain one of the world’s largest fisheries, worth more than $200 million at the docks in 2023. Used as bait, the fish are critical for valuable commercial targets such as Maine lobster. They’re also beloved by sportfishermen.

The modern industry is dominated by Omega Protein, a Reedville, Virginia, company that is a subsidiary of Canadian aquaculture giant Cooke. The company pushed back at the idea that fishing is the cause of osprey decline, although it did acknowledge that fewer menhaden are showing up in some parts of the bay.

Federal data show osprey breeding is in decline in many parts of the country, including where menhaden is not harvested at all, said Ben Landry, an Omega spokesperson. Climate change, pollution and development could be playing a role, said Landry and others with the company.

Blaming fishing 鈥渏ust reeks of environmental special interest groups having an influence over the process,鈥� Landry said.

New rules could be on the way

The menhaden fishery is managed by the Atlantic States Marine Fisheries Commission, an interstate body that crafts rules and sets fishing quotas. Prompted by questions about ospreys, it created a work group to address precautionary management of the species in the Chesapeake Bay.

In April, this group proposed several potential management approaches, including seasonal closures, restrictions on quotas or days at sea, and limitations on kinds of fishing gear. The process of creating new rules could begin this summer, said James Boyle, fishery management plan coordinator with the commission.

The osprey population has indeed shown declines in some areas since 2012, but it’s important to remember the bird’s population is much larger than it was before DDT was banned, Boyle said.

鈥淭here are big increases in osprey population since the DDT era,鈥� Boyle said, citing federal data showing a six-fold increase in osprey populations along the Atlantic Coast since the 1960s.

Environmentalists says bird’s decline could worsen

To a number of environmental groups, any decline is too much. This irritates some labor leaders who worry about losing more jobs as the fishing industry declines.

Kenny Pinkard, retired vice president of UFCW Local 400’s executive board and a longtime Virginia fishermen, said he feels the industry is being scapegoated.

鈥淭here are some people who just don’t want to see us in business at all,鈥� he said.

But Chris Moore, Virginia executive director for Chesapeake Bay Foundation, said the country risks losing an iconic bird if no action is taken. He said Watts’s studies show that the osprey will fail without access to menhaden.

鈥淥sprey have been a success story,鈥� Moore said. 鈥淲e’re in a situation where they’re not replacing their numbers. We’ll actually be in a situation where we’re in a steep decline.鈥�
