London, Birds from every continent except Antarctica have been photographed nesting or tangled in waste, the BBC News reported.
Photos were submitted by people from all over the world to an online project called Birds and Debris.
The scientists running the project say they see birds ensnared - or nesting - in everything from rope and fishing line to balloon ribbons.
The focus of the project is on capturing the impact of waste - particularly plastic pollution - on the avian world.
"Basically, if a bird builds a nest using long fibrous materials - like seaweed, branches or reeds - the chances are it will have human debris in its nest somewhere," said Dr. Alex Bond from the Natural History Museum in London, and one of the researchers involved.
The project, which he and his colleagues have been running for four years, aims to draw attention to the widespread problem of plastic waste in the environment.
"When you start looking for this stuff, you'll see it everywhere," he said. "And this has really illustrated the huge geographic scope - we had reports from Japan , Australia, Sri Lanka, the UK, North America - it's truly a global issue."
In a recent study, the team looked into how many of the photos being submitted feature pandemic-related personal protective equipment (PPE). They found that it featured in almost a quarter of the photographs submitted.
"It's almost all masks," said Dr. Bond. "And if you think of the different materials a surgical mask is made from - there's the elastic that we see tangled around birds' legs or we might see birds injured by trying to ingest the fabric or the hard piece of plastic that secures it over your nose.
"The researchers say they want to highlight the "systemic problem" that leads to so much debris ending up in the environment.”
