Janeen Grell peered out of her car window Sunday and noticed a bunch of little black things lying along Route 222 in Spring Township. "What's that?" she said to her husband. "Oh, my God," she said an instant later. "They're birds." Grell, 37, of Reinholds estimated that 50 to 100 black birds were lying dead on or along the highway, just north of the ramp from Route 724. Just what killed so many birds in such a concentrated area remains a mystery. Though a definitive number of dead birds could not be established, there were enough for Spring police to turn the matter over to the Pennsylvania Game Commission for investigation. Officials there could not be reached Sunday. It is believed the birds are European starlings. Harry D. Brown III, executive director of the Animal Rescue League of Berks County, was not aware of the incident but theorized on possible causes of the deaths. Brown, a certified animal control officer, ruled out West Nile virus. It's unlikely that a virus would claim the lives of that many birds in such a small area, he said.
SINKING SPRING, Pa.—Dozens of birds found dead along highway over the weekend apparently were killed with a poison that's legal for farmers to use, state game officials said.
The USDA notifies the game commission when it targets the birds but did not do so recently, so the commission assumes a farmer set out the poison, game commission spokeswoman Cheryl Trewella said.
In 1966 it was reported that Starlicide is lethal to starlings with an acute oral LD50 of 3.8 milligrams per kilogram body weight, but less toxic to most other birds. Grain-eating game birds [such as bobwhite quail,[4] pheasants (Phasianus colchicus) and rooks (Corvus frugilegus)[5]] were acknowledged to be more vulnerable. Hawks and mammals were resistant to the poison. Starlings were killed in a slow, "nonviolent" death by uremic poisoning and congestion of major organs.[6] The effect was described as "a grayish white, frost-like material of uric acid overlaying the serosal surfaces of the various organs, accompanied by sterile inflammation and necrosis in the affected and adjacent tissues" akin to avian visceral gout.[5] The site of action is believed to be in the kidney[7] Uses for CPTH include killing blackbirds on sprouting rice[8] and on corn and soybean fields.[9] For these and other uses the poison is often given with brown rice. Research continues to improve the effectiveness of delivery on brown rice by causing the poison to be retained on the bait longer and resist degradation by sunlight.[10][11] The effect of the poison is believed to be cumulative: for example, the LC50 for starlings was 4.7 ppm over 30 days, but only 1.0 ppm when fed for 90 days.[4] In 2009, a culling with DRC-1339 received national attention after USDA employees dispensed the poison in Griggstown, New Jersey to kill an estimated 5,000 starlings that plagued feed lots and dairies on local farms. When "it began raining birds" community members became alarmed, unsure whether a toxin or disease was at work. Two property owners in the area reported collecting over 150 birds each from their land.[12][13] In January 2011, there was another incident in Yankton, South Dakota, causing public alarm. The USDA had poinsoned the birds in Nebraska to protect farmers feeds.
CAUTION: Starlicide is toxic to chickens, turkeys and other poultry, the bait should not be placed in areas accessible to these species.
Starlicide Complete is a Restricted Use Pesticide for use only by a Certified Applicator or persons under their direct supervision and only for those uses covered by the Certified Applicator certification.
A slow acting avicide in a complete feed bait. Kills starlings and blackbirds around livestock and poultry operations.
