European Honey-buzzard vs Hen Harrier

In short

The European Honey-buzzard and Hen Harrier can be distinguished primarily by their flight silhouette and behavior. The Honey-buzzard has a longer tail and a more pigeon-like head, while the Hen Harrier is more slender with a distinctive facial disk. Both species can be seen in open habitats, but their flight patterns and structure are key to identification.

Identification tips

1. Flight silhouette: Look for the Honey-buzzard's longer tail and pigeon-like head versus the Hen Harrier's slender body and facial disk. 2. Flight behavior: Note the Honey-buzzard's soaring with flat wings compared to the Hen Harrier's low, gliding flight. 3. Plumage details: In males, the Hen Harrier's grey plumage is distinctive; females have a white rump patch. 4. Habitat: Consider the habitat; Honey-buzzards are more likely in wooded areas, while Hen Harriers prefer open fields and marshes.
