Drones and artificial intelligence show promise for conservation of farmland bird nests

July 14, 2020

Summary: Every spring, a large number of ground-nests of farmland birds are accidentally destroyed by mechanical operations, such as ploughing and sowing. A new study shows for the first time that such nests can be located using a drone in combination with artificial intelligence.

Trump’s New Chant: “More White People!”

The Damage Report host John Iadarola is joined by TYT’s very own Jayar Jackson to break down all of today’s major news for you!

The Trump Admin. is now taking full control over Covid-19 data, ensuring all information used to track the pandemic is withheld from the public and stripping the CDC of its most basic responsibility. Trump’s interview with CBS News yesterday did not go well, to say the least: from claiming we’re over-testing for Covid-19, to blaming China because “they hit us with the plague,” to then defending police brutality as well as the use of the confederate flag –it wasn’t pretty. Biden has released a new, more ambitious climate plan —but does it go far enough? Geraldo Rivera is, for some reason, defending Ghislaine Maxwell.

TRUMP SNAPS ‘SO ARE WHITE PEOPLE’ WHEN ASKED WHY BLACK PEOPLE ARE KILLED BY COPS President Donald Trump took umbrage with a question a CBS News reporter asked about Black Lives Matter on Tuesday. Reporter Catherine Herridge asked the president in an interview why he thought Black Americans were being shot by police officers. “So are white people. So are white people. What a terrible question to ask. So are white people,” Trump said. “More white people, by the way. More white people.” Black people are 2.5 times as likely as white Americans to be shot and killed by police officers. [HuffPost]

Caspian terns in Oregon, USA

This 19 July 2015 video says about itself:

One of the Caspian Tern Colonies in Hamilton, Ontario, Canada

The Terns share the island with hundreds of Double-Crested Cormorants and lots of Gulls. The adult Terns are bringing fish back to the colony and then the search begins for their young. It is not an easy task and you will see lots of youngsters trying to mooch food, but the adults will only feed their own. In the last scene, a Tern finally finds its juvenile and feeds it. Another adult fails when a Gull steals the fish.

From Oregon State University in the USA:

Predation by Caspian terns on young steelhead means fewer return as adults

July 14, 2020

Caspian terns feeding on young fish have a significant impact on runs of steelhead in the Columbia River, research by Oregon State University suggests.

Through detailed analysis of steelhead survival and Caspian tern predation rates, the researchers found that the birds are not only preying on fish that would perish for some other reason, but are adding to the annual death toll by eating steelhead smolts that would have survived without tern pressure.

In scientific terms, the findings indicate that the terns are having an “additive” effect on prey mortality rather than a “compensatory” one.

The study was published in Ecological Applications.

In the Columbia Basin, 13 of 20 populations of anadromous salmon and steelhead are listed as threatened or endangered under the Endangered Species Act. Caspian terns, a protected migratory bird species native to the region, have been the object of predator management in the Columbia Basin in an effort to protect smolts, especially steelhead smolts, from being eaten before they can swim downstream to the ocean.

The largest breeding colony of Caspian terns in the world was formerly on a small island in the lower Columbia River estuary between Oregon and Washington. It hosted more than 10,000 breeding pairs in 2008, just prior to implementation of nonlethal management to reduce colony size to between 3,125 and 4,375 breeding pairs.

“There has been little research, however, into whether reduced predation actually results in greater overall salmonid survival, either at the smolt stage, where the predation is taking place, or across the lifetime of the fish,” said Oregon State’s Dan Roby, professor emeritus in the Department of Fisheries and Wildlife of the College of Agricultural Sciences. “Without clear evidence that reduced predation means greater survival to adulthood, management to reduce predator impacts would be a waste of time and resources.”

To tackle the question, Roby and collaborators at Real Time Research, Inc., of Bend and the University of Washington looked at 11 years’ worth of mark-recapture-recovery data for almost 80,000 steelhead trout smolts from the Upper Columbia population that were tagged and released to continue their out-migration to the ocean.

After release, the tagged fish were exposed to predation throughout multiple stretches of river on their journey toward the Pacific. The tag-recovery data made possible estimates of the weekly probability of steelhead survival, mortality from being eaten by birds and death from other causes.

“This approach allowed us to directly measure the connection between smolt survival and tern predation,” Roby said.

Estimates of tern predation on steelhead were substantial for most of the years studied, he said. And increases in tern predation probabilities were connected with statistically significant decreases in steelhead survival for all of the years evaluated and both of the fish life stages studied: smolt out-migration and smolt-to-adult returns.

“Our results provide the first evidence that predation by Caspian terns may have been a super additive source of mortality during the smolt stage and a partially additive source in the smolt-to-adult life stage,” Roby said. “A persistent pattern was clear: For each additional 10 steelhead smolts successfully consumed by Caspian terns, about 14 fewer smolts from each cohort survived out-migration.”

Another pattern: On average, for every 10 steelhead smolts eaten by terns, one fewer individual from each cohort returned to the Columbia Basin as an adult.

“Our model shows that mortality from tern predation was primarily additive and therefore has a credible, significant impact on prey survival,” Roby said. “Predator-prey models need to consider additive effects of predation across life stages to avoid exaggerating potential benefits from management actions aimed at reducing predator populations to enhance prey populations. The primary value of the study is by analyzing the true effects of natural predators on populations of their prey, and thereby assessing the conservation value to prey of managing predators.”

Roby notes that the study by OSU, Real Time Research, and the University of Washington contradicts recently published research by scientists with the U.S. Fish and Wildlife Service and the Fish Passage Center, who found that steelhead mortality due to tern predation is compensatory.

That paper, in the Journal of Wildlife Management, suggests that “management efforts to reduce the abundance of the [tern] colonies are unlikely to improve the survival or conservation status of steelhead.”

Dutch bosses neglect workers’ coronavirus safety

‘You didn’t answer the question’ — Betsy DeVos couldn’t justify Trump’s push to reopen schools nationwide this fall.

Translated from Dutch NOS radio today:

About one in five workers say that their boss is increasingly lax with the coronavirus rules. This is evident from a survey that Maurice de Hond conducted among 2500 workers on behalf of the [Christian ‘moderate’] trade union federation CNV. Especially workers in industry (29 percent), ICT (24 percent) and in healthcare (24 percent) see that their employers no longer take the rules too closely.

“The number of coronavirus infections is increasing faster than ever worldwide. Since July 1, 2.5 million new coronavirus cases have been added. In Spain, two regions have again locked down. So the danger is far from over,” said CNV chairman Piet Fortuin. “In this light, it is strange that so many employers are now dealing more laxly with coronavirus rules. We call on them to continue to adhere to the guidelines.”

Nearly one in five employees say they do not feel safe at work because of COVID-19. 29 percent of those who work for national government feel unsafe. This is 35 percent in health care and 21 percent in education.
