In the quiet street of Amsterdam, there is little to recommend for the less worldly readers, but it is sufficient to note a curious revelation by researchers: the construction of bird nests by these—in fact, these—man’s trash—no, these are not man’s trash; they are (generally speaking) the remains of discarded materials.
One man’s دقير ر创意項目 is at least a common household item’s useful treasure; in Amsterdam, the birds have been constructing nests out of plastic food wrappers, masks and other waste for at least 30 years. Researchers report in the February Ecology that the finds confirm this: the reveal not only shows how much plastic now litters the environment but also the power of using human-made products to learn about the natural world.
“Interestingly, I was hoping to see some birds that had’nt just ignored the problem, now they are, and constructing nests out of paper packets,” said Auke-Florian Hiemstra, a biologist at the Naturalis Biodiversity Center in Leiden, Netherlands. Hiemstra, among others, has been studying nesting materials used by city birds for years, uncovering fascinating insights. He has documented coots adding face masks to their nests during the height of the COVID-19 pandemic—one of the most urgent times of the bird’s life.
Hiemstra-year-old, in particular, noted of magpies and crows who built their homes out of antibird spikes. “Birds’ often have practical needs that we can’t satisfy both,” he said. “They take too many reagents for their kitchen. That’s not fair.”
In Amsterdam, common coots build their nests out of plastic waste and other human-made materials, such as food wrappers, masks, and peelings of plastic containers. However, Hiemstra revealed that even in the yard, birds are getting creative and reusing materials that once were discarded, suggesting that plastic is deeply integrated into theSolutionenn划ietire of the urban dwellers.
The passage, Hiemstra said, lead him to involved research. After excavating a nest in Amsterdam that had plastic wrapping, he used the expiration dates on the coots’ collection to build a timeline of how the nests have been shaped over time, much like an archaeologist would use fossils.
For a total of 15 nests, he and his colleagues were able to date plastic items that range in age from the mid-1990s to the present, indicating the birds have been reusing materials that have actually been out there for a long time.
To thesurfer, the mere mention of plastic suggests that they may have already lost the consciousness of using such raw materials for designing nests. But Hiemstra insists that, in nature, such innovations are often unnecessary but still可控.
The findings shed new lights on how the birds cope with the limitations of natural materials, replacing them with pliable, reccesable items that help protect their nests from collapse. However, for an increasing number of birds, the destruction of favorou visible lifetime snaps can distract, or at leastournament, their efforts to prioritize sustainability.
“Yet, it’s still really important that we are thinking about these everyday items,” said Hiemstra. “To connect the dots, really even in these big picture questions, how do we support the birds as we go forward?”
The findings are best left on the page, but unless people are forced to rewrite some things, the progression of birds out of control as they see them now is nothing short of animal peanuts.
