Birds of prey, also known as raptors, are among the most captivating and formidable creatures in the animal kingdom. They have exceptional eyesight that enables them to spot prey from great distances, incredible agility and speed that allow them to swoop in and catch it swiftly, along with talons and beaks that are sharp enough to efficiently capture and consume their meals.
However, there’s much more to learn about these intriguing, albeit slightly fearsome, avian predators. If you’re passionate about wildlife, particularly birds of prey, there’s a wealth of fascinating facts waiting for you.
From their ancient origins to their unique adaptations and the tricks they employ to make migration easier, there’s so much to explore. If you’re eager to deepen your understanding of birds of prey identification, continue reading!
Scientists believe they are descendants of dinosaurs
Indeed, it's true! Scientists assert that today’s birds of prey are descendants of dinosaurs. This is because raptors evolved from carnivorous dinosaurs, known as theropods, that roamed the Earth around 150 million years ago.
These theropods included fierce predators such as the Velociraptor Mongoliensis, which may remind you of the one portrayed in the Jurassic Park films. Contrary to popular belief, however, researchers have discovered that these dinosaurs bore a closer resemblance to the flying raptors we see today.
Evidence suggests that these ancient hunters were feathered rather than scaled, sharing features with modern birds of prey like hawks and eagles, including the distinctive long claw on the second toe of each foot. While films depicted this claw as a weapon for slashing, it’s now believed that Velociraptors used their claws to grip and hold down prey, much like today’s predatory birds.
When the asteroid impact and volcanic eruptions that ended the age of dinosaurs took place, most of these creatures went extinct, but birds of prey survived. Thus, they are indeed direct descendants of the Jurassic period.

Birds of prey have unique evolutionary traits
The evolution of birds of prey differs from that of many other animals and even other bird species. Typically, animal features evolve over time through natural selection, resulting in species that are better adapted to their environments. However, raptors have not undergone this evolutionary flexibility; instead, their skull shapes are remarkably consistent, changing only in predictable ways related to size.
Unlike other birds, where beak shapes can evolve separately from skull shapes, for birds of prey, the beak's form is closely tied to the skull. This has led to a slower evolutionary process compared to other bird species, which have diversified into numerous forms.
Their lifecycle offers insight into environmental health
The lifecycle of birds of prey is not only fascinating but also crucial for monitoring various environmental conditions.
The annual lifecycle of these raptors can be broken down into four key stages:
- Autumn migration
- Spring migration
- Summer nesting
- Wintering
Understanding how these apex predators operate during these phases is vital to comprehending their conservation status and needs. Many North American birds of prey undertake extensive migration journeys each year, traveling from as far north as Alaska to as far south as South America.
During the warmer months, they nest in northern regions to raise their young. As winter approaches, they migrate south to find more abundant food sources. This cycle continues year after year.
While migrating in autumn and spring, birds of prey can cover thousands of miles, often crossing multiple borders and habitats, leading to non-native raptors appearing in the UK at various times of the year.
Unlike many other bird species, birds of prey typically lay only 2 to 4 eggs in a nest, with a maximum of 2 likely to survive to fledging. Numerous factors can lead to nest failures, including human disturbances, food shortages, and habitat encroachment due to development.
Winter presents the greatest challenges for birds of prey, as competition for limited resources peaks. To cope, these raptors often congregate in areas rich in prey during winter, returning to these locations year after year if they prove fruitful.
Studying birds of prey is crucial for understanding environmental changes. As they are particularly vulnerable to ecological threats, raptors serve as an indicator species. Changes in their behaviour and declining populations can signal serious issues that could endanger them and other wildlife if not addressed promptly.
They employ strategies for migration
As raptors migrate, they expend significant energy and face numerous dangers. To facilitate their journeys, they have developed strategies that are passed down through generations:
During migration, birds of prey utilise:
- Thermals – Warm air rises when the sun heats the Earth's surface, allowing them to soar and gain altitude.
- Updrafts – Gusts of wind hitting mountainous regions create updrafts that birds of prey use to gain height and navigate peaks.
- Leading lines – To avoid getting lost, birds of prey follow geographical features like coastlines and ridges that guide them in their migrations.
- Obstacles – To prevent fatigue, birds of prey avoid large bodies of water, where thermals do not form as effectively.
