More than 10,000 bird species have been identified so far. The hummingbird is one example of a little bird, whereas the ostrich is an example of a non-flying bird. Vultures, of all flying birds, are the biggest.
9. Marabou Stork
The Marabou Stork is endemic to the dry and semiarid regions south of the Sahara. This kind of bird, which is commonly seen in garbage dumps, may get as heavy as 17 pounds. When viewed in profile, this black bird seems like it is donning a pair of white briefs. Some birds have been said to reach wingspans of up to thirteen feet, although these sightings are extremely rare. Even while birds attain sexual maturity at a very young age—around four years—they tend to maintain the same partner throughout their lives. They are beggars who make their homes near human communities.
8. Northern Royal Albatross
The wingspan of a northern royal albatross is 10 feet. The Chatham Islands, Taiaroa Head, and the South Island of New Zealand are home to this endangered bird species. Despite continued grounds for alarm, the trend line shows a steady increase. This kind of bird averages 16 pounds and waits until age 8 before starting a family. They eat fish that have washed up on the beach or are floating near the water’s surface and are either dead or dying.
These birds have complicated courting rituals that take place both on land and in the air. On the coast, they use plant materials to construct enormous nests. The incubation of the egg and the care of the young are tasks shared by the male and female birds.
7. Andean Condor
The Andean condor is endemic to the Andes. Bolivia, Chile, Colombia, Ecuador, and Peru all use it as their national emblem. This bird, which averages 29 pounds, is classified as Vulnerable. This bird seldom flaps its wings once it’s airborne, preferring to glide rather than fly. The lifespan of this black-and-white bird is estimated at 50 years. About six years into its lifespan, it reaches sexual maturity.
Only one other bird species has been found to exhibit sexual dimorphism, and it is this one. Males often sport a sizable comb at their crown. They are unable to communicate because they lack syringes. When they are eating near a ship, you could hear clucking or hissing sounds.
