Pollution is all around us. It is in the air that we breathe, the water we drink and the food that we eat. But humans are not the only ones combating the problems of poor air quality and food and water laced with chemicals. Birds are highly susceptible to almost all forms of pollution, from chemicals that make up water pollution to the excess noise from cities. Read on to learn about the effects of pollution on birds.
Some people just want some peace and quiet, and apparently, so do the birds. The University of Colorado at Boulder has conducted a three-year study that proves that ?noise pollution? affects birds and their habits. The biggest problem that birds face when there is too much noise is their ability to communicate. Birds that vocalize at lower frequencies are easily drowned out by noise pollution, affecting their ability to attract a mate and socialize with the other birds in their community. But finches and other birds that vocalize at a higher frequency appear uninfluenced by the hustle and bustle of noise pollution – apparently ignoring the mass exodus of their fellow, winged friends.
Birds that live near bodies of water (called ?water birds?) can be greatly affected by what is known as ?oil pollution?. Approximately 500,000 water birds are killed every year due to oil spills. When birds unexpectedly happen upon an oil spill in their aquatic environment, the oil coats their feathers and causes them to stick together. Feathers ordinarily provide a waterproof protection for birds, but when the feathers are covered in oil they lose this quality. This causes some of their skin to become exposed and at risk to the elements. Birds who attempt to clean their feathers will often ingest the oil and become ill or even die from poisoning.
There is such a thing as too much light, at least, in the bird world. Bright city lights look beautiful at night when viewed from a distance, but that is no consolation for the bird that cant find the way home. Birds use the bright stars in the sky to determine their route for the next day, and when the city lights interfere with their view, birds can become confused and disoriented.
?Light pollution? can affect the flight patterns of birds, rendering their usual migration paths impossible to follow. City birds are also finding it very difficult to sleep with all of the bright lights, and some birds have become uncharacteristically active at night. Unfortunately, light pollution also causes some birds to succumb to deadly collisions with buildings and other objects in the sky that may be difficult to see when “blinded by the light.”
Think twice before you send that helium balloon up into the sky. Heavy winds commonly lead balloons to the ocean, and many a bird has been found with a balloon string hanging from his beak or wrapped around his neck. But balloons are just the beginning. Municipal, agricultural and industrial waste account for the majority of ?water pollution? throughout the world. Pesticides and heavy metals that are leaked into rivers, lakes and streams can cause illnesses and death in birds, threatening individual species. Water pollutants can also reduce the amount of oxygen in the water that eventually kills fish in a process called ?eutrophication?. Birds that rely on fish as a source of food will often need to move to other areas to feed, causing an upset to the natural balance of the ecosystem.
Poor air quality due to smog and noxious gases can have a devastating effect on the bird population in dense areas. Not surprisingly, these pollutants have even drifted up into the polar regions, putting the lives of arctic birds at risk. Birds have very high respiratory rates, which make them even more susceptible to pollutants in the air and to airborne impurities.

For birds, at least, there is such a thing as too much light. From a distance, the bright city lights appear lovely at night, but that doesn’t bring comfort to the bird that can’t find its way home. Birds utilize the bright stars in the sky to plan their daily course, so when city lights obstruct their view, they may get lost or confused.

Pollution is all around us. It is present in the food we eat, the water we drink, and the air we breathe. However, humans are not the only ones battling the issues of bad air quality and chemically contaminated food and water. Birds are extremely vulnerable to practically all types of pollution, including excessive city noise and the chemicals that contaminate water.

When it was discovered that eggshell thinning in raptors and other bird species was a global problem, there was public outcry and, by the 1980s, DDT use in agriculture was outlawed in the majority of countries. Many raptors and other impacted species have seen an increase in breeding success as a result of this ban.
Finding DDT’s contribution to these declines required some research. Derek Almey Ratcliffe, a well-known conservationist, observed an odd rise in the number of broken and missing eggs in raptor nests in the UK during the early 1950s. These nests were primarily used by Peregrine Falcons, but there were also Golden Eagles and Sparrowhawks. Ratcliffe noticed that these cracked eggs’ eggshells had become thinner and less heavy over time. This eggshell thinning caused hatching failure and reduced productivity. In response to these worries, the BTO conducted a nationwide breeding survey in 1961 and 1962, which found that the number and reproductive success of UK Peregrines had decreased. But why was the eggshell thinning occurring? Additional reasoning revealed that DDT was the reason, given its growing use since it was first made available in the UK in 194445.
Neonicotinoid insecticides have gained attention recently as an alternative kind of pesticide. These substances are absorbed and circulate throughout the entire plant, including the seeds, pollen, and nectar. Neonicotinoids’ effects on the environment are still being studied in its infancy. Nonetheless, because they persist in the environment, it is believed that they have a compounding effect on invertebrates and their predators. According to preliminary data, neonicotinoids have a deleterious effect on the growth, reproduction, and behavior of certain bee species, farmland birds, and aerial insectivores. Neonicotinoids used as seed treatments have no overall, consistent effect on farmland bird populations, according to recent UK research. Nonetheless, this study did discover adverse relationships with populations of House Sparrows and Skylarks. Despite the EU’s 2018 ban on the three main neonicotinoids’ outdoor use, agricultural crops worldwide continue to be treated with them.
The world’s nighttime satellite imagery makes it evident how heavily populated urban areas are lit up. Artificial light at night (ALAN) can change the orientation and navigation of nocturnally migrating birds in addition to having an impact on the species that live in these areas. Many people may die as a result of this, as light attraction or disorientation causes people to crash into buildings and other structures. Seabird fledglings can also be disorientated by ALAN. Some species’ chicks, such as Manx Shearwaters and Puffins, fledge at night to lessen their chance of being eaten. On the other hand, ALAN may cause colonies close to populated areas to be grounded on land during their initial flights. Teams of volunteers look for grounded fledglings to release back out to sea in areas where this happens regularly.
Another highly noticeable type of pollution is plastic, particularly when it covers our beaches. It is estimated that 4. 812. Every year, 7 million metric tonnes of plastic end up in our oceans. It is therefore not surprising that marine species encounter it. It is estimated that over 2056 percent of seabird species worldwide have been impacted by anthropogenic debris, primarily plastic, either by ingestion, entanglement, or incorporation into their nests (which can, in turn, create an entanglement risk). Additionally, we find more examples the more species we examine.
