Bird watching continues to be a popular hobby. Now a recently upgraded
website can help people track where the birds are. The GLRC’s Chuck
Cornell University and the National Audubon Society have set a website
called eBird.org. The site has compiled years of observations
from amateur birdwatchers across North America. Chris Wood is Cornell’s
eBird project manager. He says the site could help people who want to
see birds while traveling.
“If you’re planning to take to a trip really anywhere in the U.S. or
Mexico, you can use eBird. There’s a tab that says view and explore
data and you can get a bar chart to show the distribution of birds that
have been seen there.”
Wood says having all the data in one place can also help scientists as
they try to learn more about bird migration patterns. He says nowadays
that could be useful in the effort to block the spread of avian flu.
Each fall, thousands of hawks, eagles, and other birds of prey fly hundreds of miles in search of warmer climates. And between August and December, nearly 70-thousand people will climb to the top of a bird sanctuary called Hawk Mountain to get a closer look at those birds.

Each fall, about thousands of hawks, eagles, and other birds of prey fly hundreds of miles
in search of warmer climates. And between August and December, nearly 70-thousand
people will climb to the top of a bird sanctuary called Hawk Mountain to get a closer
look at those birds. The Great Lakes Radio Consortium’s Brad Linder reports:
“Those of you haven’t found the osprey, it’s over there at owl’s head, naked eye here to
On a clear day, the view from atop Hawk Mountain stretches for more than fifty miles.
But on this particularly hazy Saturday afternoon, bird-watchers are pushing their
binoculars and telescopes to the limits.
“Well, we’re making them out there, they’re coming in. It’s like you just gotta wait ’til
they get a little closer than what they typically do. They’ve been popping out of clouds
and haze all day for us.”
Doug Wood is a volunteer at Hawk Mountain in Eastern Pennsylvania. This afternoon,
he’s the official bird counter.
“We’re basically taking a lot of field information. Wind, weather, temperature, cloud
cover, wind direction. And then we’re basically monitoring the birds’ species, age, sex,
and recording it every hour.
“Look! An Osprey! And then fade to scene change.”
Researchers at Hawk Mountain have been keeping records of osprey and other migratory
raptors for more than seventy years, making it the oldest monitoring station in the world.
In the early twentieth century, hunters would shoot thousands of birds from the
mountainside each year. Today, people travel from all over the world to shoot birds with
Matt Wong came all the way from New Zealand to study at the sanctuary.
“Hawk Mountain is internationally renowned as a hawk watch site. And also a place
where big research actually happens. Now, not many of the locals around Pennsylvania
actually realize this, but it’s actually huge on the international scene. It’s world
recognized, and that’s one of the reasons why I came here.”
In Wong’s country, there are only two species of raptors. In America, he’s had a chance
to study dozens of varieties.
But even with so many different species populating North America, many people still
think of them as strangers or sometimes even as monsters.
“I still get, amazingly to me, a lot of people that think that these birds are out to get us.”
Volunteer Bob Owens has spent the last 20 years doing education programs at Hawk
“If you intrude into their territory when they have young in the nest, or something like
that, yeah, they’re probably going to chase you. As far as them killing babies and taking
them from baby carriages, this is all old wives tales. This just does not happen.”
Owens runs a small farm for a living, where he says hawks and barn owls help keep
rodents under control. But in a larger sense, Owens says there’s a lot people can learn
from these birds.
“Any three and a half pound bird that can apply four hundred pounds of pressure with its
talons is built to do what they’re doing. They are at the top of the food chain. And that’s
the other big thing that it shows us. It just opens up a door here as to all the reasons the
birds are either dropping or rising in population. What are we doing?”
Owens says in the seventy years researchers at Hawk Mountain have been counting birds,
they’ve seen populations rise and fall. Hawks and eagles are hardy birds. But even the
most successful predators can fall victim to environmental change.
Keith Bildstein is the sanctuary’s director of conservation programs. He says raptors are
like sensitive tools, telling researchers when something’s wrong with an ecosystem.
“Birds of prey are excellent biological indicators. In the middle of the last century they
told us that we were having a problem with our misuse of organochlorine pesticides,
specifically DDT. Today, they’re leading us in explorations of the spread of West Nile
Bildstein says because raptors are at the top of the food chain, when their numbers fall
it’s a pretty good sign that their food source is dwindling, their habitat could be
disappearing, or air quality might be suffering.
But for most of Hawk Mountain’s visitors, the birds are more than barometers of a
healthy ecosystem. According to birder Judy Higgs, they’re beautiful creatures,
especially when viewed from a great height.
“These birds are just majestic. And the other thing is that they go so far. You know,
some of these birds are going to South America!”
Higgs first climbed the mountain in 1970, when she was a student at nearby Kutztown
University. Before moving out of state, Higgs used to come to Hawk Mountain daily…
she stills visits on weekends whenever she can.
“I used to do work in the morning, come here in the afternoon, go home, and finish my
work at night so I could be here.”
By day’s end, Higgs and her fellow birdwatchers count more than 600 raptors. During
the fall season, as many as 70-thousand predatory birds, from vultures to falcons might
pass by on their way to distant points.
