Both crested eagles and falcons are fascinating birds of prey, each with their unique characteristics, adaptations, and hunting strategies. This comparison will delve into the intricate details of these birds, focusing on their physical attributes, hunting techniques, and evolutionary history.
Physical Attributes of Crested Eagles and Falcons
Crested eagles (Morphnus guianensis) and falcons, particularly the Peregrine Falcon (Falco peregrinus), have distinct physical characteristics that set them apart.
Size and Weight
- Crested eagles are large birds, with males weighing between 2.5 to 4.5 kg (5.5 to 9.9 lbs) and females weighing between 3.5 to 6.3 kg (7.7 to 13.9 lbs).
- Falcons, on the other hand, are smaller birds, with the Peregrine Falcon being the largest species, weighing between 330 to 1,500 g (11.6 to 52.9 oz).
Wingspan
- Crested eagles have a wingspan of 165 to 200 cm (65 to 79 in).
- Peregrine Falcons have a wingspan of 94 to 110 cm (37 to 43 in).
Beak
- Crested eagles have a robust, hooked beak, which they use to tear their prey apart.
- Falcons have a sharp, toothed beak (tomial teeth) that they use to kill their prey.
Tail
- Crested eagles have a short, broad, and wedge-shaped tail.
- Falcons have long, pointed wings and a long tail.

Crested eagles and falcons employ different hunting strategies to capture their prey.
Crested Eagles
Crested eagles are powerful hunters that primarily target arboreal animals, such as sloths and monkeys. They use a sit-and-wait strategy, perching quietly in the forest canopy before swooping down on their prey.
Falcons
Falcons are high-speed hunters that use their incredible agility and speed to catch their prey in mid-air. They are known for their spectacular dives, or “stoops,” which can reach speeds of over 320 km/h (200 mph).
Evolutionary History of Crested Eagles and Falcons
Crested eagles and falcons belong to different orders, but their evolutionary history is fascinating.
Classification
Crested eagles belong to the order Accipitriformes, while falcons belong to the order Falconiformes. However, recent studies have shown that falcons are more closely related to parrots than to eagles, illustrating the concept of convergent evolution.
Real-life Incidents and Statistics
Crested Eagles
Crested eagles are considered endangered, with a population of fewer than 1,000 mature individuals. They are threatened by habitat loss and fragmentation, as well as hunting and persecution.
Falcons
Falcons are more widespread and abundant than crested eagles, with the Peregrine Falcon being one of the most common falcon species in the world. However, they are still threatened by habitat loss, pesticide exposure, and collisions with man-made structures.
