These great and good-looking animals are native to Eurasia and North America. 
In scientific language, they are known as Canis lupus lupus. They have a general body mass of 40 kg(88lb). The most heavy wolf recorded is 79.4kg(175lb).
The lightest wolf recorded to date is 12kg(26lb). Females are generally 2.3-4.5kg(5-10lb).
Wolves have dense fur, which protects them from intense winter. This fur is also known as guard hair. Wolves in northern areas can rest openly at -40°C.
Wolves are pack hunters, i.e., they hunt in groups for food. They are very competitive hunters compared to other predators. Wolves are monogamous, which means they live their whole lives with the same mate. When one mate dies, the other tries to find a new mate or lives solely.

2) Beavers

These cut and adorable animals are the next and the cutest examples of couples for their whole life. These are scientifically known as genus castor. They are one of the largest rodents present in the entire world. They are of two breeds American and Eurasian beavers. Beavers are the second largest living rodents after capybara. They can weigh up to 50 kg(110lb). They have a stout body, a large head, long incisor teeth, and Brown or gray fur. Beavers have nearly 12,000 to 23,000 hair per centimeter square. The beaver's coat has the function of keeping the animal warm, helping it to float in water, and protecting it against predators. In contrast, guard hairs are five to six centimeters long and are typically reddish brown, but can range from yellow-brown to nearly black. The underfur is long and dark grey. Beavers molt their hair every summer. They are herbivorous in nature. Also, they are monogamous which means they only mate with a single partner.

3) Macaroni Penguins

The next animal in the list is the Macaroni penguin also scientifically known as Eudyphtes chrysolophus. It is a species of penguin found in the subantarctic to Antarctic peninsula. They are very closely related to the royal penguin and can grow up to 70 cm(28 inches) in length and weigh up to 5. 5 kg or 12 pounds. Males and females are similar in appearance while males are slightly larger and strong whereas they also have larger beaks. Macaroni penguins are also known to travel nearly 10, 000 kilometers in a year through the central Indian Ocean with about 18 million individuals. It is also one of the most numerous penguin species in the world. The diet of Macaroni Penguin consists of a variety of Crustaceans, squid, and fish. The proportions that each mix up vary with locality and season. Female macaroni penguins breed around five years of age while males do not normally breed until they are six. Females breed at younger ages because the male population is larger in these species. Also, the sexual pairs formed at the start of life, last long the whole life and it rarely happens that they mate with another penguin showing the sign of true love.

4) Bald Eagles

This beautiful yet dangerous bird is Bald Eagle. Yes, the national bird of the United States of America. Its scientific name is Haliaeetus Leucocephalus. It is also known as the Bird of Prey and is found in North America. So, these birds usually feed on fish, which they swoop down and snatch the fish from the water along their talons. It has the largest nest in the whole world. It can be up to one metric ton(1. 1 short tons) and can be up to 4 meters deep and 2. 5 meters wide. It achieves sexual maturity of up to four to five years. It can reach up to 56-70km/hr(35 to 43 mph) when gliding and flapping, and about 48 km/hr(30 mph) while carrying fish. It climbs at a speed of 120 to 160 km/hr(75 to 99 mph). It consumes a variety of prey, but mainly it consumes finish and mostly found salmon. It migrates generally during the daytime, usually between the local hours of 8AM to 6PM, when thermals are produced by the sun. The males are 25 percent larger than the females. Bald eagles may have only one mate in their whole life, and when that mate dies, they find their new mate to continue the rule over the territory.

5) Sandhill Crane

One of the most different and unique of all species is the Sandhill Crane. It is a species of large crane, mostly found in North America and in extreme northeastern Siberia. Their common name refers to their habitat, such as the Platte River and the edge of Nevarezca Sandhills on the American Great Plains. They are known for their frequent edge over the body water. Sandhill cranes are known to frequent the edge over the bodies of water. The average weight of the larger male is 4. 57 kg(10. 1 lb), while the average weight of the female is 4. 02 kg(8. 9 lb), with a range of 2. 7 to 6. 7 kg(6 to 14 lb) across the subspecies. They have red foreheads, white cheeks, and long dark pointed bills. In flight, their long dark legs trail behind and their long necks keep straight coming forward. Sandhill cranes are mainly herbivorous, but they also eat varying types of food, depending upon the availability. They generally eat cultivated food such as corn, wheat, cotton seeds, and sometimes sorghum. They need long-term energy, which they fulfill from such herbivorous food for long journeys. In breeding season, Sandhill Crane raises one brood per year, and their non-migratory population lays eggs between December and August. They usually have only one mate in their whole life and it takes nearly 10 to 9 months for the next breed to begin.

6) Swan

Last but not the least, the most beautiful, the most iconic, and the most attractive bird in the world Swans. They are the closest relative to geese and ducks and lie within the family of Anatidae. Swans in the scientific name are known as Cygnus. These are the largest living species and they have many types but they can reach up to lengths of over 1. 5 m(59 in) and weigh over 50 kg (33 lb). Their wingspan can be over 3. 1 m(10 ft) and as compared to their related birds geese and ducks they are larger in size, feet, and neck. Swans have webbed feet for their movement in water, and can also survive on land. They feed in both water and on land. Their diet is mostly herbivorous, which also contains some amount of aquatic animals. Their food is obtained by swimming or dabbling in water. Their diet is mostly composed of roots, tubers, stems, and leaves of aquatic and submerged plants. In ancient times, swan meat was considered the most luxurious food in England during the reign of Elizabeth I. Also, the most important and interesting fact about swans in the love life is that they survive for 24 years and start breeding at the age of 4 to 7 years. They form monogamous bonds as early as 20 months and they live in this patch for about the next 20 years. And the divorce rate is very rare.
