(Beyond Pesticides, August 27, 2018) Beyond the visual and audial charms of some bird species, insect-eating birds play a significant role in controlling pests that can ruin crops or ravage forests. A meta-study by Martin Nyffeler, Ph.D. of the University of Basel in Switzerland finds that globally, birds annually consume 400-plus million metric tons of various insects, including moths, aphids, beetles, grasshoppers, crickets, and other arthropods (invertebrate organisms with exoskeletons, paired and jointed appendages, and segmented bodies, such as insects, crustaceans, and spiders). This research reviews 103 studies that examine the volume of insects consumed by various birds in seven of the world’s major biomes. In consuming such volumes of insects that can inflict damage on crops, trees, and other plants on which organisms may feed or otherwise depend, birds provide significant services to ecosystems, to denizens of habitats, and to human food system and economic interests; they also keep local ecosystems in balance. Threats to birds — and thus, to those ecosystem services — include those from pesticide use. Of the 10,700 known bird species distributed across the planet, more than 6,000 are primarily insectivorous. The study indicates that forest-dwelling birds consume the majority of insects (approximately 300 million metric […]

(Beyond Pesticides, July 6, 2018) Two years ago, thirteen bald eagles were found dead on a farm in Maryland. Now the investigation has revealed that these birds died after ingesting the highly toxic pesticide, carbofuran. Carbofuran, whose use has been phased out in the U.S., is so toxic to birds that one granule is all it takes to kill. Irresponsible and illegal use of pesticides is still responsible for primary and secondary poisonings of wildlife, as is the case of these bald eagles. According to the necropsy results by U.S. Fish and Wildlife Service (FWS), which analyzed six of the thirteen eagle carcasses, five of the carcasses were found to have undigested raccoon remains in their systems. Carbofuran was detected in the stomach and/or crop contents of all birds, as well as on the partial remains and fur of a raccoon that was found nearby. The granular form of carbofuran has been blamed for the deaths of more than a million birds in the U.S. who mistook the granules for seed. The granules were finally banned in the early 1990s, while the liquid formulation was banned on food crops in 2009, although the painfully slow process of cancellation by the U.S. […]

(Beyond Pesticides, May 30, 2018) Six environmental groups have sued the Trump Administration for reversing a long standing interpretation of the Migratory Bird Treat Act (MBTA) that provides migratory bird protections from incidental killing or “taking” caused by industrial activities. The lawsuit, National Audubon Society v. Department of the Interior, was filed May 24, 2018 in the Southern District of New York, challenging as “unlawful and arbitrary and capricious the December 22, 2017 Solicitor’s Memorandum M-37050, which was issued by the office of the Solicitor of the Department of the Interior (“DOI”) and reverses Defendants DOI’s and the U.S. Fish and Wildlife Service’s (“FWS” or “Service”) longstanding interpretation and implementation of the Migratory Bird Treaty Act of 1918.” The Act’s prohibition on the killing or “taking” of migratory birds has long been understood to extend to incidental take from industrial activities — meaning unintentional but predictable and avoidable killing. Last year, the Trump Administration issued a Memorandum gutting federal protections for migratory birds under the Migratory Bird Treaty Act (MBTA). The plaintiffs, including American Bird Conservancy, Center for Biological Diversity, Defenders of Wildlife, National Audubon Society, National Wildlife Federation, and the Natural Resources Defense Council, are seeking to protect waterfowl, […]

(Beyond Pesticides, January 4, 2018) Last month, the U.S. Environmental Protection Agency (EPA) released the preliminary ecological (non-pollinator) assessments for the neonicotinoids (neonics); clothianidin, thiamethoxam, dinotefuran, and the terrestrial ecological assessment for imidacloprid, finding that these pesticides pose both acute and chronic risks to aquatic life and birds. Treated seeds are identified as posing the highest dietary risks to birds, confirming previous research that neonics are highly hazardous not only to bees, but to birds, aquatic life, and other non-target organisms. Released December 15, 2017, EPA opened the public comment period for these assessments until February 20, 2018. Along with the risks identified in the assessments, the agency is specially requesting feedback on the benefits of continued use of the neonics in cotton and citrus crops identified in last year’s pollinator assessments as posing risks to honey bees. EPA states, “We believe early input from the public will be helpful in developing possible mitigation options that may be needed to address risks to bees.” This despite evidence of long-term systemic exposures to non-target organisms that support a phase-out of these pesticides. EPA believes that neonicotinoids are crucial for the management of Asian citrus psyllid, an invasive pest that causes citrus greening, […]
