Curiosity in a School Lab Killed the Crows, Robins, and Sparrows

UN LAB Middleware Label: Title Ends

Update: February 16, 2022
Great news! PETA has just obtained documents from the state of Colorado showing that in 2021, Colorado State University (CSU) experimenter and bird tormentor Gregory Ebel kept his hands off birds, including crows, robins, and sparrows. Ebel’s horrendous experiments—in which he kidnaps healthy birds from their natural homes, infects them with West Nile virus, and then kills them—have failed to help birds or humans with the disease.

Please tell CSU that you want to make sure this development is permanent by taking action below.

Update: In response to a legal complaint and request for an investigation by PETA, Colorado Parks and Wildlife (CPW) cited and fined Colorado State University's (CSU) Gregory Ebel and suspended his license. However, new documents obtained by PETA reveal that before CPW rescinded his license, Ebel had trapped 32 American robins in order to infect the birds with West Nile virus. PETA is calling on the agency to seize any surviving robins from Ebel's laboratory and transfer them to a reputable wildlife rehabilitation facility.

Ebel has spent 13 years capturing crows and other birds in the wild, holding them captive in his laboratory, infecting them with West Nile virus, and killing them—but he's failed to develop a cure, a vaccine, or any clinical treatments for the disease, either for birds or humans. Crows are highly intelligent, sensitive animals who value their freedom, their families, and their lives.

The documents obtained by PETA also reveal that Ebel is now getting his hands on crows and robins by enlisting the help of a fellow CSU experimenter, Richard Bowen, who has his own trapping license. In addition to infecting birds with deadly viruses and bacteria, Bowen traps fox squirrels, deer mice, and cottontail rabbits for his own painful and deadly experiments. Like those of Ebel, his experiments aren't aimed at developing any treatments for infectious diseases—they're just curiosity-driven. These taxpayer-funded experiments wreak havoc on wildlife while diverting public health dollars to pointless experiments.

PETA is calling on CSU to pull the plug on Ebel's experiments. We've also filed a complaint with the U.S. Department of Agriculture after determining that the university failed to include the birds who were trapped, used, and killed by Ebel in its reports to the federal government, as required by law.

Experimenters at Colorado State University (CSU), led by Gregory Ebel, are using our tax dollars to trap American crows, American robins, and house sparrows; infect them with West Nile virus (WNV); watch as they develop symptoms from the infection; and kill them. Confinement alone causes tremendous stress to the trapped birds, and this is compounded when they're injected with WNV strains and subjected to multiple blood draws, including from their jugular veins.

The birds are kept alive while the virus makes its way into their major organs—the lungs, heart, liver, kidneys, and spleen—and central nervous system. They may develop a fever. They lose their appetite and have difficulty controlling their bodily movements. Some species—including American crows—experience systemic infection throughout their bodies followed by multiple organ failure and death.

WNV has had a devastating impact on bird populations, particularly of American crows. But the purpose of Ebel's work isn't to develop a vaccine or treatment for the virus—or to gain new insights into prevention strategies. Rather, these are curiosity-driven experiments, aimed at understanding the behavior of the virus in different host species as an academic matter.


These experiments don't help birds or humans: Ebel has acknowledged that viral mechanisms—how severely a virus attacks the host (virulence) and its ability to cause disease in the host (pathogenicity)—differ radically between bird species. For example, American crows are highly susceptible to and experience high rates of mortality from WNV, whereas American robins are susceptible to the virus but experience low death rates. And these mechanisms are different in humans as well.

Moreover, WNV can be controlled by eliminating mosquito breeding sites. But Ebel has received more than $5.3 million from the Fauci-run National Institute of Allergy and Infectious Diseases since 2007 to conduct these experiments—and so they continue.

The birds who are trapped, tormented, and killed by CSU experimenters value their freedom, their families, and their lives. A growing body of evidence has documented that crows are remarkably intelligent and profoundly social beings. They're able to solve complex problems, understand analogies, use tools, delay gratification, and recognize individual human faces—distinguishing between friends and foes (such as Ebel).

Please tell CSU to pull the plug on Ebel's cruel and worthless experiments.
