Mystery illness strikes down birds across US south and midwest

"A mysterious illness is killing birds across several states in the south and midwestern US, and wildlife scientists are rushing to try to find the cause, with many victims suffering from crusty eyes, swollen faces and the inability to fly.

Wildlife managers in Washington, Virginia, Maryland and West Virginia first began receiving reports of sick and dying birds with eye swelling and crusty discharge, as well as neurological signs in late May, according to a statement from the US Geological Survey, which added: “No definitive cause of death is identified at this time.”

In Kentucky, the department of fish and wildlife resources is asking the public to report encounters with sick and dead birds through a new online reporting system. They say the species affected thus far have included blue jays, common grackles and European starlings, but other species may also be affected. More than 20 samples have been sent out for testing.

In Ohio, the Ohio Wildlife Center posted on Facebook that it has been admitting songbirds with eye issues and is working with authorities to help determine what might be causing local birds to become sick. Indiana wildlife officials said they tested the birds for avian influenza and west Nile virus, and the samples came back negative.

Bird mortality events are not all that uncommon. Last year, hundreds of migratory birds dropped dead in New Mexico in a massive die-off.

After analyzing samples and testing theories, the New Mexico department of game and fish eventually concluded that the birds had died from starvation and unexpectedly bad weather.

“Migrating birds entered New Mexico in poor body condition and some birds were already succumbing to starvation,” the agency wrote. “The unusual winter storm exacerbated conditions, likely causing birds to become disoriented and fly into objects and buildings. Some were struck by vehicles and many landed on the ground where cold temperatures, ice, snow and predators killed them.”

According to a 2007 study, mass mortality events are often tied to weather.

This new disease-fueled die-off comes at a time when birds are facing unprecedented challenges. The US has lost more than a quarter of bird populations in just the last 50 years, according to a 2019 study. The study authors write: “This loss of bird abundance signals an urgent need to address threats to avert future avifaunal collapse and associated loss of ecosystem integrity, function, and services.”

A record-breaking heat wave that descended on the Pacific Northwest, USA

Temperatures in Portland, Oregon, soared to 116 which topped a previous all-time high. (116 degrees = 46,6°C)

"We’re going to have to get used to this going forward,” said Kristie Ebi, a professor at the University of Washington who studies global warming and its effects on public health.

The 2021 Western North America heat wave is an ongoing extreme heat wave in much of the Pacific Northwest and Western Canada, particularly, in western Nevada, Northern California, Oregon, Washington and Idaho in the United States, as well as British Columbia, and in the later phase, Alberta, Saskatchewan, Yukon and Northwest Territories in Canada.[1] The heat wave also affected inland areas of central and Southern California,[2] as well as northwestern and southern Nevada, though the temperatures were not as extreme as compared to the regions farther north.

The heat wave appeared due to an exceptionally strong ridge centered over the area and the effects of climate change.[3]

The heat wave caused some of the highest temperatures ever recorded in the region,[4] including the highest temperature ever measured in Canada at 49.6 °C (121.3 °F).

The heat wave increased air conditioning usage, triggered flooding due to rapid snow melt, caused wildfire conditions, disrupted agriculture, and degraded transportation infrastructure. During the heat wave, over 100 more deaths than average were recorded in Greater Vancouver within a four-day period.
