#Together Against Rabies: APHIS-Wildlife Services Works to Prevent Rabies

World Rabies Day is held every year on September 28.

World Rabies Day is held every year on September 28.

This year’s World Rabies Day theme “Together Against Rabies” is appropriate given the number and diversity of organizations around the world focused on preventing the spread of rabies in people, pets, livestock and wildlife.

Since 2007, the Global Alliance for Rabies Control has sponsored World Rabies Day on September 28 to promote rabies awareness and reduce rabies transmission. For its part, the APHIS-Wildlife Services (WS) program has been working cooperatively with local, State, and Federal governments, international partners, universities and others since 1995 to prevent the spread of rabies in wildlife in North America.

Recovering a Native: USDA Agencies Help with Endangered Ferret Reintroductions

You can hear the chattering and scurrying from far away as six endangered black-footed ferrets restlessly wait in their travel carriers.  These animals are the first of more than thirty scheduled for release this fall onto 34 square miles of prairie habitat at the Soapstone Prairie Natural Area and Meadow Springs Ranch in northern Colorado. The site is one of several new areas recently offered by local, State and Federal land management agencies and private landowners as reintroduction sites to aid in the recovery of the endangered black-footed ferret— America’s only native ferret.

Once thought to be extinct, black-footed ferrets are making a comeback thanks to a successful captive breeding program, multiple reintroduction sites across the West, and the hard work of many government agencies, non-governmental organizations, Tribes, private landowners, and concerned citizens.

How do you find something that doesn’t want to be found – something that has evolved to be cryptic, elusive, and stealthy?  That is the question asked of APHIS geneticist Dr. Antoinette Piaggio. She and others at the National Wildlife Research Center (NWRC) – the research arm of the APHIS Wildlife Services program – are investigating new ways to track and locate invasive Burmese pythons.

Burmese pythons have made a home in Florida competing with and feeding on native wildlife. Experts agree that new tools and techniques are crucial to monitoring and controlling the spread of this elusive snake.

“Burmese pythons are semi-aquatic and can be very hard to detect given their elusive nature and cryptic coloration,” states Piaggio. “We’ve developed a new detection method that uses environmental DNA, thereby eliminating the need for seeing or handling snakes.” Read more »

American Farmers Benefit from APHIS Bird Repellent Research

California is the “bread basket” of American agriculture. In 2012, California’s 80,500 farms and ranches produced a record $44.7 billion in produce, dairy, and meats. With more than 400 crop varieties grown in the State, California produces nearly half of all U.S. grown fruits, nuts and vegetables.

To help ensure this basket stays full, the California Department of Food and Agriculture (CDFA) partners with APHIS Wildlife Services (WS) to address wildlife damage issues to agriculture. Some of the more recent work involves the development of repellents to protect crops from birds. Read more »

We Can’t Barbecue Our Way Out: Why Feral Swine Management Requires a National Approach

Invasive feral swine have spread rapidly across the United States as a result of natural range expansion, illegal trapping and movement by people, and escapes from domestic swine operations and hunting preserves.

Invasive feral swine have spread rapidly across the United States as a result of natural range expansion, illegal trapping and movement by people, and escapes from domestic swine operations and hunting preserves.

Wild boar, razorback, feral hog, wild pig — these are just some of the names we attribute to one of the most destructive and formidable invasive species in the United States. Feral swine adapt to just about any habitat, have few natural enemies, and reproduce at high rates. As such, their population is growing rapidly nationwide. At 5 million animals and counting, feral swine are now found in at least 39 States and cause approximately $1.5 billion in damages and control costs each year. Their damage is diverse and includes destroying native habitats and crops, eating endangered species, and spreading disease. Natural resource managers, researchers and academics nationwide are grappling with how best to address the challenges of feral swine management.

Feral swine are hunted by the public in some States for recreational purposes; but hunting will not solve our country’s feral swine problems. Read more »

An Airport is No Place for an Owl

USDA airport biologist Bobby Hromack holds his first captured short-eared owl. Although it weighs no more than 16.8 ounces, the species can pose an aviation safety hazard due to its 33-43 inch wingspan and low, rolling flight style.

USDA airport biologist Bobby Hromack holds his first captured short-eared owl. Although it weighs no more than 16.8 ounces, the species can pose an aviation safety hazard due to its 33-43 inch wingspan and low, rolling flight style.

Seeing a short-eared owl in November on the Pittsburgh International Airport, where I work as an airport wildlife biologist, was a unique occasion. However, as the number of owls grew to eight, I recognized the challenge ahead:  Like all birds of prey, short-eared owls are a recognized potential aviation hazard. Their low rolling flight and difficult-to-disperse reputation means they pose an aviation safety threat.  From 1990-2012, short-eared owl strikes with aircraft in the United States caused over $1 million in damage, and often are fatal to the birds.  Convincing them to leave would be difficult but important.

The task would be harder because short-eared owls are listed by the State as an endangered species.  Common in many areas globally, Pennsylvania is the southernmost edge of their breeding range.  These owls likely migrated from Canadian breeding grounds to winter in Pennsylvania. Read more »
