New Studies Highlight Impact of Outdoor Cats on Birds and Other Wildlife

This week–National Wildlife Week–scientific organizations announced two new studies that provide more evidence of the havoc outdoor cats wreak on wild birds and other wildlife.
“Crime Against Nature”
On March 15, The Wildlife Society said it was “taking a strong stand in favor of keeping pet cats indoors and removing feral cats from the environment to protect wildlife from cat predation.”
As part of this effort, the spring 2011 issue of the organization’s magazine, The Wildlife Professional, features a series of articles, “In Focus: The Impacts of Free-Roaming Cats.” The articles highlight problems that outdoor, stray and feral cats cause for wildlife and wildlife habitat as well as for animal and human health.
Among The Wildlife Society’s findings:
- The number of free-roaming cats is increasing, currently between 117 million and 157 million in the United States alone. The domestic cat, Felis catus—a nonnative species—is now the most abundant carnivore in North America.
- While cat numbers are rising, nearly one-third of more than 800 U.S. bird species are endangered, threatened or in significant decline.
- By some estimates, outdoor cats in the United States kill more than 1 million birds every day on average. Other studies suggest the death toll is as high as 1 billion per year.
- Outdoor cats transmit rabies, toxoplasmosis, typhus, plague and other viral and parasitic diseases to both wildlife and humans.
According to the society’s executive director, Michael Hutchins: “Allowing free-ranging pet and feral cats to roam outside, breed unchecked, kill native wildlife and spread disease is a crime against nature.”
The #1 Predator for Catbirds? Cats.
Another new study, on the effects of urbanization on wildlife and published in the Journal of Ornithology, tracked the early lives of gray catbirds in three suburbs of Washington, DC. Conducted by Peter Marra and Thomas Ryder of the Smithsonian Institution and Anne L. Balogh of Towson University, the study involved affixing very small radio transmitters to 69 newly hatched gray catbird chicks. The transmitters recorded the birds’ locations every other day until the animals left the study area or died.
Of the 42 young catbirds that did die, nearly 80 percent were killed by predators, and domestic cats were responsible for nearly half the known predation.
“While this study was not national in scope, it certainly adds more validation to what we’ve been saying for years: that outdoor cats are a highly destructive predatory force that is causing havoc in the world of native wildlife,” says Darin Schroeder, vice president for conservation advocacy at the American Bird Conservancy, an organization that has long advocated keeping cats inside.

I heard 1 cat extinted a whole bird race from New Zealand. So yes i would believe this

Your anti-feline propaganda does not convince me.

What I don't understand is why the government of the U.S. doesn't work with environmental groups to save our remaining unraped birds and small creatures.
We need an immediate government mandated killing off of a good portion of domesticated cats and there needs to be draconian sterilization laws passed in respect to cats and those that aren't sterilized need to be forcibly put to sleep as a pro-nature initiative.
We have little time before the U.S. bird populations are literally decimated.

Evolution, natural selection. The birds and other animals will learn how to adapt to the cat. End of story. Every species on this planet has been an invasive species at one time or another. It's how nature works.

I like that someone pointed this out because cats usually go along with vegetarians or animals first people who fail to realize they are caring for the most invasive species in history.

The worst devastation caused by cats takes place on remote islands, where there are no human settlements. We many have put them there-- but what if they went there naturally through some sort of weird migration? Does that make it alright then?
If we're going to start removing invasive species, let's start with Homo Sapiens. Small mammals being wiped out? Cats kill rats en masse, rats are the most invasive species on the planet. Those rats are literally on every continent, even Antarctica (due to human bases there). And cats are also known for going after squirrels & rabbits, those mammals' numbers are artificially high due to humans. Also, rabbits destroy tons of crops. If people aren't using cats to keep their numbers down they will use rabbit-hunting dogs or ferrits.Literally whole bird species and small mammal/reptilian species are being wiped out.
This is not natural. Domesticated cats are essentially anti-nature when buoyed by human benevolence.
And Mammals are amazing at adapting, that's how we got where we are. I'm sure they will come up with plenty of ways to avoid/survive cats. I'm not worried about it.

I'd say simply kill off the cats that have gone feral.
