Take swallows, for example. Although swiftlets and swallows are in the same category, they have very different lifestyles. Swiftlets cannot stand on their feet; they can only cling to walls. They have sharp eyes to catch tiny insects quickly during the day but have poor vision at night, so they must return home before dark. Because of this, they have developed a unique skill called the “echolocation system,” which allows them to accurately find obstacles by emitting sounds." They originated from their ancestors in the theropod group, who were small, meat-eating creatures covered in feathers. After drastic environmental changes that wiped out most other species, birds survived due to their small size, adaptability, and ability to fly. The feathered creature can’t fly, but it has strong legs and interesting features that point to its evolutionary history. They’re also one of the most dangerous birds, as their four-inch-long, sharp talons can injure humans if they’re provoked into attack. Additionally, birds contribute significantly to human culture, recreation, and scientific research. Different bird species have different roles; humans were inspired to invent airplanes by observing birds’ habits. Of course, there are still many unique functions in nature that humans have not been able to replicate." One way to do that is to avoid using chemicals in our yards, such as grass fertilizer and pesticides. If we kill insects, there won’t be anything for them to feed on. Not to mention the deaths caused by poisonous chemicals. Instead of polluting their environment, we should plant native greenery so they have shelter and nourishment widely available.
