Birds of prey

In the traditional or morphological sense, "birds of prey" usually refers to birds that catch or tear prey with sharp claws and beaks, such as eagles, falcons, kites, vultures, owls, etc. However, from the perspective of modern phylogenetics, these birds of prey are scattered in different orders and are not a monophyletic group. Birds of prey are one of the six major ecological groups of birds, covering all species of Falconiformes and Strigiformes in the traditional classification system of birds. Birds of prey include secondary ecological groups such as eagles, eagles, buzzards, kites, vultures, kites, ospreys, falcons, owls, and owls, all of which are predatory birds. In the ecosystem, the number of raptors is less than that of other groups, but they are at the top of the food chain and play a very important role. Another nickname is "fighter".

I. Introduction to Raptors

1. General Characteristics

  • Predatory Adaptations: Raptors typically have strong, hooked beaks and sharp talons for seizing and tearing prey.

  • Acute Vision: Most raptors possess exceptionally keen eyesight, allowing them to spot potential prey from great distances or high altitudes.

  • Flight Abilities: Many exhibit wide or pointed wings for soaring or high-speed dives; others have shorter, broad wings and long tails for agile flight in forested areas.

  • Top Predators: As apex or near-apex predators, they help control populations of small to medium-sized vertebrates (rodents, reptiles, amphibians, other birds, etc.) in their ecosystems.

2. Classification and the Non-monophyletic Issue

  • Traditional Grouping: “Birds of prey” often include “diurnal raptors” (eagles, hawks, falcons, vultures, etc.) and “nocturnal raptors” (owls).

  • Modern Systematics: Molecular data reveal that raptors are scattered across different lineages:

    • Many hawks, eagles, Old World vultures, etc. are grouped into Accipitriformes.

    • Falcons belong to Falconiformes, which is surprisingly closer to parrots (Psittaciformes) and songbirds (Passeriformes) than to hawks or eagles.

    • Owls form their own order, Strigiformes, separate from hawks and falcons.

3. Evolution and Global Spread

  • Raptors, as descendants of early Cenozoic birds, diversified especially in the Eocene and Oligocene epochs.

  • They are found worldwide in virtually every habitat—tropical rainforests, deserts, polar regions, alpine zones—each adapted to local ecological niches.

4. Ecological Role and Human Interactions

  • As apex predators or scavengers, raptors have a major influence on regulating populations of other animals.

  • Human cultures often admire and utilize raptors (e.g., falconry, ecotourism). However, conflicts arise with livestock farming, and threats such as habitat loss and poisoning have caused declines in some raptor populations.


II. Major Groups and Classification of Raptors

Traditionally, raptors are divided into:

  • Diurnal Raptors: Historically included in Falconiformes (falcons, hawks, eagles, vultures, etc.), but modern taxonomy splits them into separate orders such as Falconiformes and Accipitriformes.

  • Nocturnal Raptors: Owls (order Strigiformes).

Below is a simplified breakdown referencing modern classifications.

(A) Diurnal Raptors

1. Order Falconiformes

FamilyRepresentative GeneraExample SpeciesDistribution & Notes
Falconidae (Falcons, Caracaras)Falco, Caracara, etc.Peregrine Falcon (Falco peregrinus), Common Kestrel (Falco tinnunculus), Crested Caracara (Caracara plancus)Once grouped with hawks/eagles but now recognized as a separate lineage, surprisingly closer to parrots/songbirds. Falcons specialize in high-speed dives or agile flight; caracaras often forage on the ground or scavenge.

Note: Modern phylogenetics places Falconidae (the only extant family in Falconiformes) closer to parrots and passerines than to hawks and eagles.

2. Order Accipitriformes

FamilyRepresentative GeneraExample SpeciesDistribution & Notes
Accipitridae (Hawks, Eagles, Old World Vultures, Kites, Harriers)Accipiter (Goshawks, Sparrowhawks), Buteo (Buzzards/Hawks), Aquila (True Eagles), Haliaeetus (Sea Eagles), etc.Northern Goshawk (Accipiter gentilis), Rough-legged Buzzard (Buteo lagopus), Golden Eagle (Aquila chrysaetos), Bald Eagle (Haliaeetus leucocephalus), etc.The largest family of diurnal raptors worldwide. Includes a wide range of sizes and feeding habits, from small hawks to large eagles and Old World vultures.
Cathartidae (New World Vultures)Cathartes (Turkey Vultures), Coragyps (Black Vulture), Gymnogyps (California Condor), etc.Turkey Vulture (Cathartes aura), Black Vulture (Coragyps atratus), California Condor (Gymnogyps californianus)Native to the Americas. They have unfeathered heads to reduce contamination while feeding on carrion. Taxonomic placement varies; commonly aligned with Accipitriformes but sometimes treated as a distinct lineage.
Pandionidae (Osprey)* sometimes within AccipitridaePandion (Osprey)Osprey (Pandion haliaetus)A fish specialist found near freshwater and coastal areas worldwide. Feet are adapted to gripping slippery fish.
Sagittariidae (Secretarybird)* sometimes within AccipitridaeSagittarius (Secretarybird)Secretarybird (Sagittarius serpentarius)Endemic to Africa. Long-legged terrestrial raptor that hunts snakes on foot; distinctive crest on its head.

Note: The exact placement of New World vultures (Cathartidae) is still debated. Some studies suggest they might be nearer to storks/herons, but most modern classifications group them with Accipitriformes.

3. Other Diurnal Raptor Notes

  • Old World Vultures (e.g., Griffon Vultures, Egyptian Vulture) are part of Accipitridae, unlike the New World vultures in Cathartidae.

  • The osprey family (Pandionidae) is often recognized as a separate family within Accipitriformes, though historically sometimes lumped into hawks (Accipitridae).

(B) Nocturnal Raptors (Order Strigiformes)

FamilyRepresentative GeneraExample SpeciesDistribution & Notes
Tytonidae (Barn Owls)Tyto (Barn Owl genus)Barn Owl (Tyto alba)Heart-shaped facial disk, widely distributed worldwide. Asymmetric ear openings help pinpoint prey by sound.
Strigidae (Typical Owls)Bubo (Eagle Owls), Strix (Wood Owls), Athene (Little Owls), Asio (Eared Owls), etc.Eurasian Eagle Owl (Bubo bubo), Long-eared Owl (Asio otus), Snowy Owl (Bubo scandiacus), etc.Nocturnal raptors with large forward-facing eyes and silent flight. Found in diverse habitats across the globe (except Antarctica).

Note: Owls share many predatory traits (talons, hooked beaks, specialized senses) but belong to a separate order (Strigiformes), distantly related to hawks/falcons.


III. Evolutionary Highlights

  1. Convergent Traits and Diversification

    • Multiple bird lineages independently evolved raptor-like features: strong talons, hooked beaks, and enhanced vision or hearing.

    • Genetic data confirm falcons (Falconidae) are more closely allied with parrots and passerines, while hawks and eagles (Accipitridae) form a different branch. Owls, although also “raptorial,” belong to yet another branch.

  2. Geographic Adaptation

    • Forest dwellers (e.g., Accipiter hawks, small falcons).

    • Open-country or desert species (e.g., buzzards, caracaras).

    • Mountain regions (Golden Eagle).

    • Polar regions (Snowy Owl).

    • Raptors occupy diverse habitats:

    • Different selective pressures have yielded wide variation in body size, wing shape, and hunting styles.

  3. Fossil Record

    • Raptors have been widespread since at least the Miocene, with some ancient raptor-like families appearing in the Oligocene. Fossil discoveries hint at once-abundant giant eagles or vultures in various regions.


IV. Summary

  1. Multiple Origins and Ecological Significance

    • “Raptors” do not represent a single evolutionary branch but rather an ecological group across different orders (Falconiformes, Accipitriformes, Strigiformes).

    • They generally serve as apex predators or scavengers, crucial for regulating populations of prey and cleaning carrion.

  2. Conservation Status and Challenges

    • Many raptor populations have declined due to habitat loss, pesticides (e.g., the famous DDT impact), poaching, and conflicts with farmers.

    • Conservation programs (e.g., reintroducing the California Condor, protecting Bald Eagles) have successfully bolstered some species, though others remain at risk.

  3. Cultural Importance

    • Raptors often symbolize power, freedom, or bravery—appearing in flags, crests, and mythologies around the world.

    • Falconry (the art of hunting with trained birds of prey) has been practiced for centuries and is recognized as an Intangible Cultural Heritage in some regions.
