UPPER LAKE, N.Y. -

fficially, the eastern cougar has not prowled the great piney woods of the Adirondacks for more than a hundred years. Though still listed as a federally endangered species, it is, in the minds of state environmental officials, a phantom - extinct, kaput.

Trouble is, people keep seeing them. And one man, Peter V. O'Shea Jr., a former New York City police sergeant turned self-taught naturalist, is on a campaign to make their presence known. He himself has never seen a cougar, also called a puma, mountain lion, panther or painter. But he has talked to scores of people who say they have, and he says he has seen cougar tracks four times in the past 20 years.

"My feeling is that in the Adirondacks, they were never quite extirpated," Mr. O'Shea said over lunch at the Lumberjack Inn here, as snow swirled outside. "Of any place they could have survived, it's here."

At six million acres, the Adirondack Park is larger than the five largest national parks put together, and though it includes towns and villages tucked among its vast wilderness, in many places one can walk for miles in any direction without hitting a private dirt road.

What Mr. O'Shea finds compelling is the credible nature of many of the cougar sightings, including several by staff members of the state's Department of Environmental Conservation.

"Hate to admit it," reads one such report made to the agency in 1997 by Kenneth Kogut, its own wildlife manager for the region that covers most of the Adirondacks. "Landed in road in front of me, looked at me and in three bounds was off into shrubs on south side of road."

Mr. O'Shea believes the reason the agency does not want to admit that cougars are living in the Adirondacks has to do with time and money. Because of the cat's endangered status, official acknowledgement would likely trigger a management plan. It could also pit environmentalists against land owners already chafing under government regulation.

But state officials maintain that there is simply no sustainable, or breeding, cougar population. Yes, there are sightings, though the overwhelming majority, they say, are misidentifications. People who glimpse the real thing - a large tawny cat weighing from 80 to 125 pounds, with a black-tipped tail - are seeing pets that either escaped or were released, officials say.

It is illegal for private citizens to keep cougars as pets in New York, but a senior wildlife biologist with the agency, Al Hicks, says people do anyway. "I'm sure a good many, after buying a cute little cougar kitten and watching it get up to 70 pounds, say, 'Wow, I can't handle this,' " Mr. Hicks said.

In a point-counterpoint essay published in 2000 in the periodical Adirondack Explorer, Mr. Hicks and Mr. O'Shea dueled over the cougar question.

Mr. Hicks noted that only two cougars had been shot in the previous 30 years. One had clearly been a captive animal, and the other appeared to be one as well. Furthermore, Mr. Hicks argued, there is no record of cougars taken by sportsmen before the 1970's, when it was legal to hunt them. "It would take many, many animals surviving over decades to have a population, and it's just not there," he said.

The agency receives a dozen or so reports of cougar sightings each year from across the state. But Mr. O'Shea said he knew of more than 40 sightings in just the past year in the Adirondacks and surrounding area. He does not try to argue that there is a sizable population of cougars in the park, maybe two dozen at most. And he does agree that a good number are escapes or releases.

But all of them? "I think you'd have to be blind to say there's nothing there," Mr. O'Shea said.

With tousled white hair and a preference for plaid flannel, Mr. O'Shea, 66, has become a one-man clearinghouse for cougar sightings in the Adirondacks. Some troopers even give excited callers Mr. O'Shea's name and phone number, rather than the state environmental agency's.

While some scientists may titter at Mr. O'Shea's passion for cougars, others show him respect. "He's a good naturalist," said Heidi Kretser, the program coordinator of the Wildlife Conservation Society's Adirondack Communities and Conservation Program in Saranac Lake. "He definitely has some great ideas about wildlife in the Adirondacks."

Mr. O'Shea, an author of nature and hiking guides, is a guest naturalist at the New York State Adirondack Park Agency Visitor Interpretive Center in Newcomb. He is also on the board of the Residents' Committee to Protect the Adirondacks, a nonprofit group, and the conservation chairman of the St. Lawrence Adirondack Audubon Society.

Mr. O'Shea suspects that many who see cougars do not bother to notify the state. His lunch companion, Sue Collins, a registered nurse, said she did not make a report, for instance, after she spotted one crossing Route 11 last summer while driving outside Potsdam. "I just gasped and the person I was driving with said, 'Did you see that?' " she recalled.

Hearing that, a couple at the next table, Dave and Patty McMahon, volunteered that they spotted a cougar in early 2002 bounding across Saranac Lake Road. "I've lived in this area for 50 years, and there's a distinct difference between a bobcat, a lynx and a mountain lion," said Mr. McMahon, a veteran hunter and trapper. "I saw a mountain lion."

Mr. McMahon said he did report the sighting to the Environmental Conservation agency. "They told me I was crazy," he said.

To be sure, there is nothing like a personal sighting to give even a skeptical wildlife expert pause. In the fall of 2001, while driving back from his country house in the Adirondacks, Bill Weber, director of the North America program at the Wildlife Conservation Society, which operates the Bronx Zoo, saw a cougar crossing the Taconic Parkway in Columbia County.

"It was just chewing up the road," he said in a telephone interview from Rwanda. "This wasn't just sauntering across the road like something used to hanging around people. It was remarkable."

Yet Mr. Weber is not sure what to make of the encounter. "If this truly is a relic population, and that's an interesting possibility, rest assured these were cougars who learned how to stay away from people and their vehicles," he said.

"But why aren't people finding kills?" he wondered. "Cat kills look different from other kills. There's a little bit of a Loch Ness problem. I saw a big cat run across a highway on a Sunday afternoon. I'm certain that it was a cougar, but it doesn't tell me there's a population out there."

In the Eastern United States, only the state of Florida acknowledges wild cougars, known there as Florida panthers. Despite extensive efforts to boost the population, fewer than 100 exist there today, according to federal officials.

Mountain lions are well established in most states west of the Mississippi River, and have recently entered Iowa, Arkansas and Missouri, according to Roland Kays, the mammal curator at the New York State Museum and the co-author of "Mammals of North America" (Princeton University Press, 2002).

In Mr. Kays's view, the sporadic sightings in the Northeast do not add up to a wild cougar presence. Ms. Kretser tends to agree. "There hasn't been a carcass or good tracks," she said. "No one has found a den per se. In places where there are cougars, these things happen. You see this stuff."

Still, Ms. Kretser finds the continuous sightings intriguing. "There is something out there,'' she said. "People are definitely seeing something."

A Wildlife Conservation Society book to be published this spring, "The Atlas of the Adirondacks," by Jerry Jenkins with Andy Keal, includes a map of puma sightings reported to the state over four decades. Those reports have risen steadily, to 89 in the 1990's from 5 in the 1960's. The atlas ranks the sightings according to plausibility, but state officials stress that none were confirmed.

Despite the skepticism, Mr. O'Shea presses on. He has interviewed state troopers, members of the clergy, schoolteachers, journalists and wildlife officials who claim to have seen cougars. He has scoured used-book stores for literature relating to the eastern cougar. His prize: yellowing articles from the 1950's and 60's about cougar sightings in the state environmental agency's own magazine, the New York State Conservationist.

He is also in touch with the Eastern Puma Research Network, a group in West Virginia that, since its founding in 1983, has recorded 5,800 sightings in the Eastern states, including 625 in New York.

Mr. O'Shea makes the case that New York State would not need to protect the cougar's habitat since whatever is roaming the state is likely a hybrid. "If there were escapes, there has been interbreeding - so we don't have an Eastern cougar anymore," he said.

Still, he would like the state to acknowledge what he regards as the probability that wild cougars are here, and the possibility that they never left. "I can't prove there's a self-sustaining population," he said. "But it's beyond sense that people would be letting pets go for 50 years, and what's more that they would be surviving."
