Despite concern from the public, substantial challenges remain in reducing and mitigating many of the most significant sources of bird mortality.
Changes in lighting on communication towers and the marking of electrical lines to stop collisions are just two examples of what can be done at little cost to industry, but overall, bird concerns are still under-valued, and the bird community must unite to encourage and incentivize positive change.
Estimates indicate that the following threats each kill more than 500,000 birds per year in the U.S., and are not adequately mitigated or compensated:
ABC prioritizes its threat reduction work based on scale and urgency of threat, perceived opportunity for progress, whether others are already tackling the issue, whether we can provide special expertise or assistance, and whether sufficient resources are available.
We also have programs focused on pesticides and toxics (which kill about 72 million birds each year), collisions with power lines, collisions with communication towers, and mining claim marker tube entrapment.
Additionally, oil spills and fishery bycatch kill fewer (but still large numbers of) high conservation priority seabirds such as albatrosses, petrels, and murrelets.
(This table currently includes only mortality-based threats. Habitat-based and climate- related threats will be added in future as comparable impact data become available.)
Due to the large numbers and broad ranges involved, estimated changes in bird mortality due to conservation interventions are currently still too approximate to be especially useful. Still, we have made significant efforts to reduce bird mortality.
ABC's Cats Indoors campaign has slowed the rate of spread of feral cat colonies and has encouraged thousands of people to pledge to keep their cats indoors. We have also stimulated a change in the national conversation about the impact of cats on birds through social and traditional media coverage and other outreach efforts.
The reduction of bird collisions with window glass is a long-term effort, but the first critical steps by ABC to engage architects, glass manufacturers, and the public is well underway. Our Bird-smart glass page is one of the most-visited on the ABC website.
Bird mortality caused by pesticides likely reduced after the cancellation and restriction of organophosphates and carbamates advocated by ABC. Recently, this progress has probably been offset by the advent of neonicotinoid pesticides, which are toxic to birds and are also contributing to a loss in insects that birds feed on.
Large numbers of mining claim markers are being removed by volunteers and claim owners with encouragement from ABC and the Bureau of Land Management.
Bird mortality caused by lighted communication towers has almost certainly reduced significantly because of an ABC law suit and outreach that led to large numbers of towers changing to strobe lights that are less likely to lure birds to their deaths.
Wind turbine-related bird mortality is increasing due to the expansion of wind power development. Despite this, ABC has encouraged the adoption of mitigation strategies and has helped to halt or mitigate at least eight major wind projects.
In addition to countering specific threats, ABC works to support overall federal funding for birds, to protect bedrock laws such as the Endangered Species Act and the Migratory Bird Treaty Act, and to support good — and oppose bad — legislation for birds.
ABC has communicated the cats indoors message to millions of Americans through social and traditional media. Since 2013, ABC has also intervened successfully on 26 state bills to protect birds from the expansion of ineffective cat management programs.
ABC's glass collisions work has certified 17 glass and window mitigation products as bird-friendly, and 650,000 square feet of bird-friendly glass installation has already been reported to ABC. ABC contributed to the establishment of a LEED credit for bird-friendly building design, and has trained more than 1,000 architects in bird-friendly design. Bird-friendly building ordinances and guidelines have been enacted in 12 jurisdictions, and a federal bird-safe building bill has been introduced in the U.S. House and Senate.
Through science-based advocacy and legal action, ABC has been instrumental in the cancellation or restriction of aldicarb, brodifacoum, carbofuran, diazinon, disulfoton, chlorfenapyr, endosulfan, ethyl parathion, phorate, fenthion, monocrotophos, bromodialone, difethialone, and rozol. ABC also engaged in a successful emergency campaign to protect Swainson's Hawks from monocrotophos poisoning in Argentina.
With Earthjustice and the Forest Conservation Council, ABC won a lawsuit resulting in the Federal Communications Commission working to reduce bird mortality caused by the lighting on tall communication towers. Their new policy now requires steady burning lights that attract birds to be replaced with strobes, reducing bird mortality by an estimated 70%. The transition is rapidly making progress, with nine percent of the remaining un-mitigated towers changing their lights in the past year. ABC has also fought specific tower construction proposals, including halting a tower close to Hawk Mountain Sanctuary, one of the worst possible locations in the U.S.
ABC filed and won a lawsuit to better protect eagles from wind turbine strikes by ensuring third-party oversight for eagle mortality monitoring. ABC filed a lawsuit with Black Swamp Bird Observatory that succeeded in halting a wind turbine project at Camp Perry, Ohio, in the epicenter of the greatest songbird migration corridor in the U.S. ABC helped to stop or modify seven additional wind developments in MO, ID, MD, VT, TX, and two Canadian provinces.
ABC is working with International Crane Foundation and industry partners to retrofit power lines in the Whooping Crane migration corridor to increase their visibility to migrating cranes.
ABC successfully advocated for the removal of lead paint from buildings on Midway that was poisoning Laysan Albatross chicks there, and, with Equilibrio Azul, helped develop new line-setting technology to protect Waved Albatrosses in Ecuadorian fisheries.
ABC successfully advocated for the inclusion of seabird protections in the Magnuson–Stevens Fishery Conservation and Management Act, and for albatross protection measures in U.S. Alaskan and Hawaiian longline fisheries that resulted in a c. 90% reduction is seabird bycatch.
ABC advocated for the Neotropical Migratory Bird Conservation Act and for its funding by congress. The Act has provided $62.2M in grants to bird conservation projects since 2002, 75% of which conserved migratory birds outside the U.S.
During 2017 alone, ABC gained traditional news and social media coverage for its main threat-focused programs: cats, glass, pesticides, and wind power that had a maximum reach of more than 454 million potential media impressions in the U.S. These break down as: Cats 139M, Glass 158M, Pesticides 25M, Wind 131M.
From 2014-2017, ABC supporters signed action alerts on a variety of policy issues a total of 202,394 times to issue messages to congress and other decision-makers.
