10 birds that reveal dinosaurs are still with us through their prehistoric traits, appearance, and behaviour

Despite the common belief that reptiles such as crocodiles and alligators are the closest living relatives of dinosaurs, birds actually provide the strongest link to these ancient creatures. All modern birds evolved from theropod dinosaurs, the two-legged group that included the colossal Tyrannosaurus Rex and smaller, swift predators like Velociraptors. Over millions of years, evolution has dramatically transformed their bodies, but birds still retain remarkable dinosaur-like traits. These include aspects of their skeletal structure, certain behaviours, and even their calls, which can echo the sounds of their prehistoric ancestors. In this way, birds serve as living windows into the age of dinosaurs, connecting the present to a world that vanished millions of years ago.

10 modern birds that strongly resemble dinosaurs

Many modern birds still carry the ancient legacy of their dinosaur ancestors. From their scaly feet and sharp talons to reptilian eyes and hunting instincts, these birds showcase traits that link them directly to the prehistoric past. Scientists consider them living reminders of evolution, offering a fascinating glimpse into how dinosaurs may have looked, moved, and survived.



Southern Cassowary (Casuarius casuarius)

The southern cassowary is one of the closest living relatives of dinosaurs. Part of the ratite group, which includes ostriches, emus, and kiwis, this large flightless bird descends from the helmeted Corythoraptor jacobsi of the Late Cretaceous. Its most noticeable feature is the casque, a helmet-like structure atop its head.

The cassowary’s low, rumbling calls are among the deepest of any living bird, producing sounds just above the human hearing threshold. Its powerful legs and clawed feet can be lethal, capable of delivering strong kicks that echo the predatory power of its dinosaur ancestors. Southern cassowaries inhabit tropical forests in Australia and New Guinea and share the planet with two other species: the northern cassowary and the dwarf cassowary.


Shoebill Stork (Balaeniceps rex)

Also called the whale-headed stork, the shoebill is a bizarre and formidable bird. Its massive bill enables it to catch and swallow large prey such as catfish, tilapia, water snakes, lizards, and even young crocodiles. Fossil evidence suggests that shoebills have existed for up to 30 million years, giving them an ancient, almost prehistoric presence.

Today, these birds inhabit dense marshlands and freshwater swamps in East Africa, including Uganda, Tanzania, South Sudan, and Zambia. Their unusual appearance and predatory behaviour make them one of the most dinosaur-like birds alive.


Kiwi (Apteryx spp.)

The kiwi, New Zealand’s unofficial national bird, has a round body, long beak, and feathers that resemble fur more than plumage. This flightless ratite looks primitive and ancient. Its calls, especially those of the females, have a deep, prehistoric quality. Remarkably, the kiwi shares a genetic connection with the Tyrannosaurus Rex, linking it directly to the age of dinosaurs.


Ostrich (Struthio camelus)

The world’s largest bird, the ostrich, can grow up to nine feet tall and weigh more than 300 pounds. Its body closely resembles the ornithomimid dinosaurs, featuring a long neck and feather-covered torso. Ostriches have two toes instead of the usual three or four, and their enormous eggs are the largest of any living bird, reminiscent of dinosaur eggs. They are also remarkably fast runners, with mature ostriches reaching speeds of 43 mph.


South Island Takahē (Porphyrio hochstetteri)

The South Island takahē is a rare, flightless bird from New Zealand. Its red legs, strong beak, and clawed feet give it a distinctly dinosaur-like appearance. Once thought extinct, the takahē was rediscovered in 1948 and now has a population of just over 400 individuals. Its prehistoric look and rediscovery story highlight its remarkable resilience.


Turkey (Meleagris gallopavo)

Although commonly associated with Thanksgiving in the United States, the turkey is a direct descendant of meat-eating theropods like the Velociraptor and T. rex. Its scaly legs and the presence of a wishbone recall the skeletal structure of its dinosaur ancestors. Observing a turkey’s legs and feet offers a clear connection to its prehistoric roots.


Chicken (Gallus gallus)

Chickens also share a genetic link with the T. rex. Studies of collagen extracted from T. rex fossils reveal a strong similarity to modern chicken DNA. Chickens’ scaly, three-fingered feet mirror the structure of theropod dinosaurs, making the humble chicken one of the closest living relatives of one of history’s greatest predators.


Hornbill (Bucerotidae)

Hornbills, especially the helmeted hornbill, possess a casque on their bill and a unique, prehistoric appearance. Their casque amplifies their loud calls, which vary across the 60 hornbill species. Found in sub-Saharan Africa, India, the Philippines, and the Solomon Islands, hornbills’ unusual shapes and sounds make them appear as though they have stepped out of the Mesozoic era.


Great Blue Heron (Ardea herodias)

The great blue heron’s long legs, elongated neck, and predatory habits link it to Velociraptor-like ancestors. With a wingspan of up to seven feet, these birds are formidable hunters that consume fish, reptiles, insects, and small mammals. Their stance and hunting technique evoke images of dinosaurs stalking prey in prehistoric wetlands.


Emu (Dromaius novaehollandiae)

The emu is the second-largest ratite, second only to the ostrich. Its long legs, three-toed feet, and bluish skin on the neck and head lend it a prehistoric look. Emus are omnivorous and can grow up to six feet tall, inhabiting every Australian state except Tasmania. Their appearance and movement often evoke comparisons with Velociraptors.
