Millions of birds have descended on a small Kentucky city
this winter, fouling the landscape, scaring pets and raising
the risk for disease in a real-life version of Alfred
Hitchcock's horror film, "The Birds."
The blackbirds and European starlings blacken the sky of
Hopkinsville, Kentucky, before roosting at dusk, turn the
landscape white with bird poop, and the disease they carry
can kill a dog and sicken humans.
"I have seen them come in, and there are enough that if the
sun is just right, they'll cloud your vision of the sun,"
said Hopkinsville-Christian County historian William Turner.
"I estimate there are millions of them."
David Chiles, president of the Little River Audubon Society,
said the fact that migratory flocks are roosting in the city
rather than flying further south is tied to climate warming.
"The weather, the climate plays a big role," said Chiles, the
bird enthusiast who also teaches biology at Hopkinsville High
"They somehow establish a roost south of where the ground is
frozen solid," he explained. "They are ground feeders,
feeding on leftover crops and insects. If the fields are
frozen solid, they can't feed."
Although the birds have not turned on humans as in the
classic 1963 Hitchcock movie featuring vicious attacks on
people in a small northern California town, the city has
taken defensive measures.
The south-central Kentucky city of 35,000 people, about an
hour north of Nashville, has hired a pest control company to
get rid of the interlopers.
Henry Jako, general manager of McGee Pest Control, said crews
use air cannons and "bird-bangers" - similar to bottle rocket
fireworks aimed into the trees where the birds roost.
The artillery attacks are disturbing some locals as well as
"It scares my little dog to death," said Christian County
Judge-Executive Steve Tribble. "I don't know what it does
other than move the birds from one tree to the next."
Jako said that in the worst-affected neighborhoods, multiple
cannons and consecutive blasts are being used to keep the
When they fly away, the birds leave behind a huge volume of
"I've got an apple tree that has almost turned white,"
Tribble said. "Any vehicle parked outside is covered up. I
guess it's good for folks that have car washes."
Historian Turner said that the blackbird invasion this year
is the worst he's witnessed since the late 1970s, when
Hopkinsville suffered a similar bird blitz.
"We aren't seeing the temperatures go as low as zero like we
used to. Now we very often don't even see temperatures in the
teens around here," Jako said. "If the birds are comfortable,
they are going to stay around," he added.
The birds also pose a serious health hazard because their
droppings can carry a fungal disease called histoplasmosis,
which can cause lung infections and symptoms similar to
pneumonia, according to the Centers for Disease Control
"It does become a matter of public health," said Dr. Wade
Northington, director of the Murray State University
Breathitt Veterinary Center, an animal disease diagnostic
facility whose territory covers a 200-mile (322-km) radius
from Hopkinsville, including parts of Tennessee, Illinois and
"The blackbirds are able to harbor this organism ... so it
can be shed in their droppings and it becomes a problem,
especially where they tend to roost in extremely high
numbers," he said.
It can cause illness in humans, and is particularly dangerous
for people with compromised immune systems or respiratory
ailments, he said. It can be fatal for canines.
Turner, who suffered histoplasmosis decades ago after
excavating family property that once held a chicken coop,
describes the disease as debilitating. "I didn't have any
energy, and I didn't have much appetite and lost weight," he
The droppings contaminate the soil, making it unhealthy for
years. It is a worry for dog owners, said Northington.
"It can be very expensive and take months to get it arrested
and get an animal cured from it," Northington said. "The
disease is very prevalent in our area."
