---|---|
Scientific Name | Gallus gallus |
Length | 14 to 18 in |
Wingspan | 24 to 36 in |
Weight | 4 to 8lbs |
The Chicken, is a subspecies of the red junglefowl, and is one of the most common domestic animals in the world. They have been domesticated for thousands of years and are raised for their meat and eggs, while some breeds are also kept for their distinctive appearances or for cockfighting.
Chickens come in a wide range of sizes, colors, and shapes depending on the breed. Their plumage can be white, brown, black, or a mixture of colors, and they often have a “comb” and “wattles,” which are fleshy, bright red appendages on their heads and necks.
Chickens are omnivorous and their diet in the wild would include seeds, insects, and even small mice or lizards. However, domestic chickens are often fed commercially produced chicken feed that provides a balanced diet suitable for their needs. Chickens require a high-protein diet to produce eggs and to maintain their health.
Hoatzin

The Turkey is a large bird native to North America. There are two species of wild turkey: the North American Wild Turkey (Meleagris gallopavo) and the Ocellated Turkey (Meleagris ocellata). Domesticated turkeys, which are primarily raised for meat, are descendants of the North American Wild Turkey.
They have a distinctive fleshy wattle or “beard” that hangs from the underside of their neck. Turkeys are covered in dark feathers, which can have a beautiful iridescent sheen in sunlight.
One of the most distinctive features of the turkey is its fan-shaped tail. Male turkeys will spread their tail feathers out into this fan shape during courtship displays. Another distinctive feature of male turkeys is their “gobble” call, which can be heard up to a mile away.
Wild turkeys are omnivores, with a diet consisting of acorns, nuts, seeds, fruit, insects, and small vertebrates. Domesticated turkeys are usually fed a diet of commercial poultry feed that is specifically formulated to meet their nutritional needs.
What birds today most resemble dinosaurs?
Modern birds such as the cassowary species (particularly southern cassowaries), the whale headed stork, american bald eagle and ostriches are said to most closely resemble the prehistoric species from a million years ago. With their large size, long legs, and striking appearance, it is not not only the ostric show many physical similarities to their prehistoric ancestors, the non avian dinosaur. These similarities are part of their evolutionary history and make them appear like modern bird examples of feathered dinosaurs. Many of these primitive bird species are endangered species today.
Theropod dinosaurs, which include the well-known Tyrannosaurus rex, are part of the same group as modern birds according to the fossil record. In fact, birds are considered the evolutionary offspring of small, feathered theropod dinosaurs. The hollow bones characteristic of birds were also present in theropods, showing another clear connection.
Are there any bird species considered living fossils?
Yes, there are several bird species that are considered living fossils due to their primitive characteristics and similarities to prehistoric creatures. The Northern cassowary and dwarf cassowary are among these that could make it into jurassic park! These birds display physical traits that are believed to be similar to those of their dinosaur ancestors.
