  Swans’ feeding habits contribute to the health of aquatic ecosystems by controlling plant growth and nutrient cycling.

Social Behavior

• Snow Goose: Snow geese are often found in large flocks, especially during migration and in wintering areas. These flocks can consist of thousands of individuals, and the birds exhibit social behaviors that promote group cohesion and safety. They also tend to travel in family units, contributing to the protection of young goslings.
• Swan: Swans exhibit variable social behaviors. While some species are more solitary, others form pairs or small family groups. Swans are known for their strong pair bonds, often forming lifelong partnerships with their mates.
  They engage in behaviors like synchronized swimming and mutual preening, which strengthen their social bonds.

Nesting Habits

• Snow Goose: Snow geese often build their nests on the ground or in shallow depressions. These nests are relatively simple, constructed with a combination of plant materials and down feathers.
  Their ground-level nesting provides camouflage and protection against predators, helping to ensure the safety of their eggs and young.
• Swan: Swans are known for building larger and more elaborate nests. They often create nests made of reeds, aquatic plants, and other vegetation.
  These nests are constructed near water bodies, floating on the surface or anchored in marshes. Swans’ nesting behaviors reflect their affinity for aquatic environments and their reliance on water for food and protection.

Nesting Sites

• Snow Goose: Snow geese typically choose nesting sites in Arctic tundra regions during their breeding season. These areas provide access to abundant food resources and relatively safe conditions for raising their young. The tundra’s open landscapes allow snow geese to establish nests in areas with good visibility.
• Swan: Swans prefer nesting sites near water bodies such as lakes, ponds, and rivers. The proximity to water ensures easy access to their primary food sources, and it also provides protection against land-based predators.
  The water also aids in maintaining the moisture levels necessary for their eggs and the development of their young.

Egg Color

• Snow Goose: The eggs of snow geese are typically olive-green to brown in color. This coloring serves as effective camouflage in their tundra nesting sites, blending with the surrounding vegetation and helping to protect the eggs from potential predators.
• Swan: Swan eggs have a consistent white color. This coloration is advantageous in the context of their nesting sites, as the white eggs stand out against the natural hues of the nest materials, making it easier for parents to spot any potential disturbances or threats.

Clutch Size

• Snow Goose: Snow geese usually lay clutches of about 3 to 5 eggs. The relatively small clutch size is reflective of the harsh conditions in their Arctic breeding grounds, where resources may be limited. Smaller clutches may allow parents to invest more energy into each individual chick’s survival.
• Swan: Swan clutch sizes can vary depending on the species. For example, mute swans often lay clutches of 4 to 7 eggs, while other species may lay fewer eggs. The larger clutch sizes of swans are indicative of their ability to find and utilize resources in more favorable environments.

Incubation Period

• Snow Goose: The incubation period for snow goose eggs lasts about 23 to 25 days. During this time, the parents take turns incubating the eggs, sharing the responsibilities of maintaining the appropriate temperature and protecting the eggs from potential threats.
• Swan: Swan eggs have a longer incubation period, typically lasting around 30 to 40 days. The extended incubation period may reflect the larger size of swan eggs and the additional time required for the embryos to develop.

Lifespan

• Snow Goose: Snow geese generally have a lifespan of around 5 to 15 years in the wild. Their relatively shorter lifespan can be attributed to the challenges they face during their long migrations, exposure to predators, and other environmental factors that impact their survival.
• Swan: Swans, in contrast, have the potential for longer lifespans. Some species of swans can live for over 20 years, with survival influenced by factors such as habitat quality, predation rates, and the availability of resources.
