American Bird Conservancy: Cats Indoors program update


ABC Welcomes Cats Indoors Program Officer – New Study Confirms Cats a Major Threat to Bird Populations

Please welcome Grant Sizemore as ABC’s new Cats Indoors Program Officer. Grant will be working to advocate for keeping cats indoors and removing feral and free-ranging domestic cats from outdoor environments. His work is an effort to minimize the risk outdoor cats pose to birds and other wildlife, human health, and the health of individual cats. Prior to joining ABC, Grant has worked for wildlife conservation through field research, public education and outreach, working cooperatively with industry, and engaging policy leaders. Grant can be contacted at gsizemore@abcbirds.org.

Outdoor Cats: Single Greatest Source of Human-Caused Mortality for Birds and Mammals, Says New Study

A new peer-reviewed study authored by scientists from two of the world’s leading science and wildlife organizations – the Smithsonian Conservation Biology Institute and the U.S. Fish and Wildlife Service (FWS) – has found that bird and mammal mortality caused by outdoor cats is much higher than has been widely reported, with annual bird mortality now estimated to be 1.4 to 3.7 billion and mammal mortality likely 6.9 – 20.7 billion individuals.

The study, which offers the most comprehensive analysis of information on the issue of outdoor cat predation, was published in the online research journal Nature Communications and is based on a review of more than 90 previous studies.  The study was authored by Dr. Peter Marra and Scott Loss, research scientists at the Smithsonian Conservation Biology Institute and by Tom Will from the U.S. Fish and Wildlife Service’s Division of Migratory Birds. It is available at http://www.abcbirds.org/abcprograms/policy/cats/pdf/Loss_et_al_2013.pdf.

According to Dr. George Fenwick, President of American Bird Conservancy, one of the leading bird conservation organizations in the U.S. and a group that has called for action on this issue for many years, “This study, which employed scientifically rigorous standards for data inclusion, demonstrates that the issue of cat predation on birds and mammals is an even bigger environmental and ecological threat than we thought. No estimates of any other anthropogenic (human-caused) mortality source approach the bird mortality this study calculated for cat predation.”

The study’s estimate of bird mortality far exceeds any previously estimated U.S. figure for cats. In fact, this magnitude of mortality may exceed all other direct sources of anthropogenic bird and mammal mortality combined. Other bird mortality sources would include collisions with windows, buildings, communication towers, vehicles and pesticide poisoning.
“The very high credibility of this study should finally put to rest the misguided notions that outdoor cats represent some harmless new component to the natural environment. The carnage that outdoor cats inflict is staggering and can no longer be ignored or dismissed. This is a wake-up call for cat owners and communities to get serious about this problem before even more ecological damage occurs,” Fenwick said.

The study estimated that the median number of birds killed by cats annually is 2.4 billion and the median number of mammals killed is 12.3 billion. About 69 percent of the bird mortality from cat predation and 89 percent of the mammal mortality was from un-owned cats. Un-owned cats are defined to include farm/barn cats, strays that are fed but not granted access to human habitations, cats in subsidized colonies, and cats that are completely feral.

The study charges that “Despite these harmful effects, policies for management of free-ranging cat populations and regulation of pet ownership behaviors are dictated by animal welfare issues rather than ecological impacts. Projects to manage free-ranging cats, such as Trap-Neuter-Return (TNR) colonies, are potentially harmful to wildlife populations, but are implemented across the United States without widespread public knowledge, consideration of scientific evidence or the environmental review processes typically required for actions with harmful environmental consequences.”

Additional Cats Indoors and TNR Information

ABC has created a new Trap, Neuter, and Release (TNR) brochure and updated the Cats Indoors brochure to raise public awareness about the impact of feral and outdoor cats on bird populations. You can order printed copies of the brochures and the DVD which ABC provides at cost. The ordering form is available at https://www.abcbirds.org/abcprograms/policy/cats/cind_orderform.cfm.

Materials can also be downloaded and the TNR video can be viewed on ABC’s youtube channel (see links below).
