Your Balloons Are Bad for Seabirds

Bad news, party planners: Your balloons are killing birds. A new study spotted by Live Science reveals that these colorful decorations often end up in our oceans, where seabirds mistake them for squid and consume them.

The team of Australian researchers studied more than 1700 seabirds belonging to 51 different species. One in three of the birds had plastic in their systems. Researchers also found that the birds had a 20 percent chance of dying after ingesting a single piece of debris. Though hard plastics were consumed in greater quantities by seabirds, balloons proved to be far deadlier. Eating them is “32 times more likely to result in death than ingesting hard plastic,” researchers write in their paper, published in the journal Scientific Reports.

“Marine debris ingestion is now a globally recognized threat,” Lauren Roman, who led the study, said in a statement. “Among the birds we studied, the leading cause of death was blockage of the gastrointestinal tract, followed by infections or other complications caused by gastrointestinal obstructions.”

The study also highlighted another startling statistic: 99 percent of all seabird species are predicted to ingest marine debris by 2050. That is of great concern in Australasia, which is home to the world's highest biodiversity of seabirds. Albatross and petrel species are particularly under threat, but the exact role that debris plays in that is not fully known.

Similarly, a survey from last December found microplastics in the guts of all seven sea turtle species that were studied, including the endangered green turtle and critically endangered hawksbill and Kemp's ridley turtles. However, these particles are smaller than balloon bits, and the consequences of ingesting microplastics are still being studied.

According to researchers, the most obvious and immediate solution is to reduce the amount of waste entering oceans.

Denver's Temperature Dropped a Record 64 Degrees In 24 Hours

One sure sign summer is over: On Wednesday, residents of Denver, Colorado were experiencing a comfortable 82-degree day. Just before midnight, the temperature dropped to 29 degrees. Between Wednesday and Thursday afternoon, the Denver airport recorded a differential of 79 degrees down to 24 degrees. At one point on Wednesday, a staggering 45-degree drop was seen in the span of just three hours.

All told, a one-day span saw a 64-degree change in temperature, from a high of 83 to a low of 19, a record for the state in the month of October and just two degrees shy of matching Denver’s all-time record drop of 66 degrees on January 25, 1872. On that date, the temperature plummeted from 46 degrees to -20 degrees.

Back to 2019: Citizens tried their best to cope with the jarring transition in their environment, to mixed success. On Wednesday, the city’s Washington Park was full of joggers and shorts-wearing outdoor enthusiasts. Thursday, only the most devoted runners were out, bundled up against the frigid weather.

The cold snap also brought with it some freezing drizzle which prompted several vehicular accidents, including 200 reported during Thursday's morning commute. It’s expected to warm up some in the coming days, but residents shouldn't get too comfortable: Melting ice could lead to potholes.

Invasive Snakehead Fish That Can Breathe on Land Is Roaming Georgia

A fish recently found in Georgia has wildlife officials stirred up. In fact, they’re advising anyone who sees a northern snakehead to kill it on sight.

That death sentence might sound extreme, but there’s good reason for it. The northern snakehead, which can survive for brief periods on land and breathe air, is an invasive species in North America. With one specimen found in a privately owned pond in Gwinnett County, the state wants to take swift action to make certain the fish, which is native to East Asia, doesn’t continue to spread. Non-native species can upset local ecosystems by competing with native species for food and habitat.

The Georgia Department of Natural Resources’ Wildlife Resources Division is advising people who encounter the snakehead—a long, splotchy-brown fish that can reach 3 feet in length—to kill it and freeze it, then report the catch to the agency's fisheries office.

Wildlife authorities believe snakeheads wind up in non-native areas as a result of the aquarium trade or food industry. A snakehead was recently caught in southwestern Pennsylvania. The species has been spotted in 14 states.
