Swans prefer to inhabit open lakes and swamps, where they thrive in serene aquatic environments. Their diet predominantly consists of aquatic plants, including roots, stems, leaves, and fruits.

However, swans are omnivorous and will occasionally consume fish, shrimp, insects, earthworms, and other mollusks and crustaceans.

Every October, swans commence their southward migration in search of warmer climates to escape the harsh winter. This migratory journey is a spectacular event, as they travel in large flocks. The migration lasts until March or April, at which point they begin their journey northward to return to their breeding grounds.

Evenings are peak foraging times for swans. During this period, they can be seen in groups, often rejoicing in the lake, splashing, and sometimes taking to the sky in graceful flight. The sight of swans, lakes, mountain peaks, and cloud shadows merging under the evening sun creates a breathtaking spectacle. At this time, swans engage in an elegant "water ballet" on the lake. They catch floating grass stems, search for fresh leaves in the water, and bend and twist their necks, drawing smooth arcs that captivate onlookers.

Swans have a strong sense of territory and are known for their protective nature. Reports of swans flapping their wings and chasing intruders are common, especially when their nests are threatened. Swans fiercely defend their territory and their families. They will attack unfamiliar creatures that come too close, particularly if their nests are at risk. This fierce defense is driven by their deep affection for their families, as swans are devoted and protective parents.

Swans are also remarkable fliers, often considered the flying champions among birds. While many birds struggle to fly beyond a few hundred meters, swans can soar to incredible heights. Swans are known to be the highest-flying birds, capable of flying over Mount Everest with ease, reaching altitudes as high as nine kilometers. This incredible ability is supported by their unique respiratory system.

Unlike humans, who only use their lungs to breathe, swans possess additional air sacs. When they inhale, these sacs store excess air, which is then expelled through the lungs during exhalation. This system allows swans to maintain efficient oxygen exchange even at high altitudes, preventing oxygen deprivation.

Swans hold a special place in human culture and are revered as symbols of beauty, purity, nobility, elegance, loyalty, festivity, and bravery. Their aesthetic and cultural value is high, making them beloved and celebrated across various cultures.

Unfortunately, swans have also faced significant threats from human activities. Historically, they were hunted for their large size and beautiful white plumage. Overhunting and the destruction of wetlands have led to a drastic decline in swan populations. The swan population that once bred in Greenland has become extinct due to excessive hunting. In Iceland, the breeding population is now limited to just 5,000-6,000 individuals, while Japan has approximately 11,000 swans. Conservation efforts are crucial to protect these magnificent birds and ensure their survival for future generations.

Swans are an integral part of our natural world, admired for their grace and beauty. Preserving their habitats and safeguarding their populations is essential to maintaining the ecological balance and the cultural heritage they represent.
