Neonics May Be Killing Birds in Addition to Bees, Groundbreaking Study Finds

In addition to devastating effects on bee populations and the pollination needed to feed humans and other species, widely-used pesticides chemically related to nicotine may be deadly to birds and linked to some species' declines, according to a new study.


Researchers at the University of Saskatchewan studied the pesticide imidacloprid, in the nicotine-linked class of chemicals called neonicotinoids, or neonics, and found that the pesticide had effects on migrating birds' health and ability to reproduce.

The scientists gave small amounts of the pesticide to white-crowned sparrows and found that the limited consumption caused the birds to lose weight and delay their migration.

Within hours of being given the neonics, the birds stopped eating and lost an average of six percent of their body weight and about 17 percent of their fat stores, making it impossible for them to complete their long flights south. The birds took at least an extra 3.5 days to recover and migrate.

"It's just a few days, but we know that just a few days can have significant consequences for survival and reproduction," Margaret Eng, an ecotoxicologist who led the study told Science magazine, where the research was published Friday.

The disruption of the species' normal migration led to decreased ability to reproduce and survive, the researchers found.

The study "causatively links a pesticide to something that is really, tangibly negative to birds that is causing their population declines," study author Christy Morrissey told the Associated Press. "It's clear evidence these chemicals can affect populations."

More than 70 percent of North American farmland bird species are currently experiencing population declines.

The research shows for the first time "behavioral effects in free-living birds as result of neonicotinoid intoxication," Caspar Hallmann, an ecologist at Radboud University in the Netherlands, told National Geographic after reviewing Eng's study.

Scientists in Europe revealed in 2017 that neonicotinoids can decimate honey bee populations, threatening food sources for humans and other species.

The European Union banned the use of neonics in 2018 due to their effects on pollinators.

The EPA announced in May it would cancel the registrations of 12 neonicotinoid pesticides, but in July, the Trump administration removed restrictions on sulfoxaflor, a neonic that's been found to kill bees in low doses.

California is bracing for rare January wildfires this week amid damaging Santa Ana winds coupled with unusually hot and dry winter weather.

High winds, gusting up to 80- to 90 miles per hour in some parts of the state, are expected to last through Wednesday evening. Nearly the entire state has been in a drought for months, according to the U.S. Drought Monitor, which, alongside summerlike temperatures, has left vegetation dry and flammable.

Utilities Southern California Edison and PG&E, which serves the central and northern portions of the state, warned it may preemptively shut off power to hundreds of thousands of customers to reduce the risk of electrical fires sparked by trees and branches falling on live power lines. The rare January fire conditions come on the heels of the worst wildfire season ever recorded in California, as climate change exacerbates the factors causing fires to be more frequent and severe.

California is also experiencing the most severe surge of COVID-19 cases since the beginning of the pandemic, with hospitals and ICUs over capacity and a stay-at-home order in place. Wildfire smoke can increase the risk of adverse health effects due to COVID, and evacuations forcing people to crowd into shelters could further spread the virus.

As reported by AccuWeather:

In the atmosphere, air flows from high to low pressure. The setup into Wednesday is like having two giant atmospheric fans working as a team with one pulling and the other pushing the air in the same direction.
Normally, mountains to the north and east of Los Angeles would protect the downtown which sits in a basin. However, with the assistance of the offshore storm, there will be areas of gusty winds even in the L.A. Basin. The winds may get strong enough in parts of the basin to break tree limbs and lead to sporadic power outages and sparks that could ignite fires.
"Typically, Santa Ana winds stay out of downtown Los Angeles and the L.A. Basin, but this time, conditions may set up just right to bring 30- to 40-mph wind gusts even in those typically calm condition areas," said AccuWeather Senior Meteorologist Mike Doll.
