Lockdowns create global appetite for feeding feathered friends

2023-08-02
(Press-News.org) A team of researchers have highlighted the role that the COVID-19 pandemic played in connecting people around the world more with our feathered friends while in lockdowns, finding a surge in interest for bird feeding information and providing more insight into global human-birds interactions.

Professor Emeritus Darryl Jones, from Griffith’s Centre for Planetary Health and Food Security, and the research team used Google search index (a valid proxy parameter from Google Trends data) and found a surge of interest in bird feeding in 115 countries after Covid-19 led to lockdowns where people stayed home.

Professor Jones, alongside lead author Associate Professor Jackie Doremus from California Polytechnic State University and Dr Liqing Li from Texas A&M University, investigated two interdependent questions:

Was there evidence of increased interest in bird feeding and related topics at a global scale after Covid-19 lockdowns, relative to before? And is species richness correlated with the level of interest in bird feeding? “We know from other work that interests in common bird species and bird feeding increased in response to Covid in the U.S. and some European countries during the Covid-19 pandemic,” Professor Jones said.

“This study first tests whether this pattern - increased interest in bird feeding in response to Covid-19 lockdowns – holds true for all countries, including those in the Southern Hemisphere.

“If so, Covid-19 lockdowns offered a way to reveal the global extent of bird feeding interest, something that is poorly understood.

“Our results asserted that bird feeding was occurring at a global scale; large increases in Google search intensity after lockdowns occurred in 115 countries that had sufficient search volumes.

“To the best of our knowledge, this is the first paper to measure people’s interest in bird feeding at a global scale.”

The authors analysed whether there was increased interest in bird feeding and wild birds at a global, individual-country scale during and after COVID-19 lockdowns compared with before. They also examined whether the level of interest in bird feeding in a country is linked to species richness.

The authors assessed the weekly frequency of search terms like “bird feeder", "bird food", and "bird bath” on Google for all countries with sufficient search volumes from January 1, 2019 to May 31, 2020 to see if an increase in bird searches occurred during each country’s specific lockdown period (generally around February-April 2020).

They also accessed nation-level bird species data from BirdLife International to measure species richness.

For a period of 52 weeks prior to lockdowns, the team found that the search intensity was, on average, similar to what it was in the week preceding lockdowns.

After about two weeks of lockdowns, a dramatic increase in bird feeding search intensity was evident. The result mirrored the interest in these topics found in the US, where bird feeding interest is well-documented.

The extensive practice of supplementary bird feeding around the world as documented in this study has broad implications for avian communities and their migratory patterns.

Professor Jones said that while providing supplementary food for wild birds could be beneficial for them in terms of survival during periods of resource scarcity and improved health, there was also evidence to suggest that bird feeding may alter ecological communities and potentially have negative effects on biodiversity.

“If bird feeding is common in other parts of the world, this could impact migration and disease patterns,” he said.

“It is imperative that we understand the global extent of bird feeding in order to gain a more comprehensive understanding of its potential impacts on both avian and human well-being at a continental and global scale.”

Regarding possible reasons for the increased behaviour towards bird feeding during Covid lockdowns, the team suggested it likely related to changes in the relative cost of alternative forms of leisure activities, as well as increases in the benefits from connecting with nature during a stressful time.

“Given the relationship between the practice of bird feeding, human mental health, and a variety of pro-environmental attributes, the implications are of great significance for human well-being and biodiversity conservation,” Professor Jones said.

“If access to other nature-based activities was also reduced, this would make bird feeding seem relatively more attractive.

“Moreover, forced time at home during lockdowns may have increased opportunities for people to notice birds in their gardens and may have piqued their interest in bird feeding.”

The team suggested future work should further explore bird feeding patterns in parts of the world with limited formal data collection and increase the cultural and biophysical diversity of settings where local bird feeding is studied.

The findings ‘Covid-related surge in global wild bird feeding: Implications for biodiversity and human-nature interaction’ have been published in PLOS ONE.

Researchers discover a novel pathway that minimizes liver injury during transplantation
2023-08-02
UCLA-led research describes the role that a protein called CEACAM1 plays in protecting the liver from injury during the transplantation process, potentially improving transplant outcomes. But the features that regulate this protective characteristic remain unknown. In a new study, to be published online Aug. 2 in Science Translational Medicine, a research team has identified the molecular factors at the root of this protection and shown how using molecular tools and alternative gene splicing can make CEACAM1 more protective, thus reducing organ injury and ultimately improving post-transplant outcomes. Prior to transplantation, a solid organ, such as a liver, has no ...

UIC leads field study on home, water safety after Ohio chemical spill 

2023-08-02
In February, the train derailment and subsequent chemical spill and fires in East Palestine, Ohio, caused an environmental emergency that led thousands of people to evacuate their homes. A multi-university study led by the University of Illinois Chicago will investigate the aftermath of that disaster, collecting data on the experiences of nearby residents and the effectiveness of communication from authorities about water, soil and air quality. For the study, the researchers will conduct surveys and interviews with residents in and near East Palestine, including counties ...

Scientists discover unusual ultrafast motion in layered magnetic materials

A common metal paper clip will stick to a magnet. Scientists classify such iron-containing materials as ferromagnets. A little over a century ago, physicists Albert Einstein and Wander de Haas reported a surprising effect with a ferromagnet. If you suspend an iron cylinder from a wire and expose it to a magnetic field, it will start rotating if you simply reverse the direction of the magnetic field.  “Einstein and de Haas’s experiment is almost like a magic show,” said Haidan Wen, a ...

Robotic grippers offer unprecedented combo of strength and delicacy

Robotic grippers offer unprecedented combo of strength and delicacy
2023-08-02
Researchers at North Carolina State University have developed a robotic gripping device that is gentle enough to pick up a drop of water, strong enough to pick up a 6.4 kilogram (14.1 pound) weight, dexterous enough to fold a cloth, and precise enough to pick up microfilms that are 20 times thinner than a human hair. In addition to possible manufacturing applications, the researchers also integrated the device with technology that allows the gripper to be controlled by the electrical signals produced by muscles in the forearm, demonstrating its potential for use with robotic prosthetics. “It is difficult ...

The Power of host social interactions in bacterial evolution

The Power of host social interactions in bacterial evolution
2023-08-02
Previous studies in humans and animals showed that hosts in a social condition (sharing the same space) harbor a more similar microbiota composition. Microbial transmission between hosts, which is increased when living in the same household, leads to similar species inhabiting the gut. However, whether bacterial evolution in the gut is affected by microbiota transmission remained unknown. To fill this knowledge gap, the researchers used an innovative in vivo experimental evolution approach, which revealed an average transmission rate ...
