Merlin vs Lanner Falcon

In short

The Merlin and Lanner Falcon are both small to medium-sized falcons, but they differ significantly in size and plumage. Merlins are smaller, more compact, and have a more uniform coloration, while Lanner Falcons are larger with distinctive facial markings and a more varied plumage. These differences are most noticeable when observed in flight or perched.

Identification tips

1. Size and Structure: Note the smaller size and more compact build of the Merlin compared to the larger, more robust Lanner Falcon. 2. Facial Markings: Look for the Lanner Falcon's dark 'moustache' stripe and pale head, which are absent in Merlins. 3. Plumage: Observe the more uniform coloration of the Merlin versus the varied patterns of the Lanner Falcon. 4. Flight Style: Merlins exhibit rapid, direct flight, while Lanner Falcons may be seen soaring more often. 5. Habitat: Consider the habitat; Merlins are more likely in open woodlands and urban areas, whereas Lanner Falcons prefer open savannas.

Size

The Merlin is smaller and more compact than the Lanner Falcon, which is larger and more robust.

Plumage

Merlins have a more uniform coloration with less contrast, typically brownish or grayish, and lack the prominent facial markings of the Lanner Falcon. Lanner Falcons have a distinctive dark 'moustache' stripe and a pale head, with more varied plumage patterns.

Behaviour

Both species are agile hunters, but Merlins are known for their rapid, direct flight and quick maneuvers, often hunting in open areas. Lanner Falcons are also agile but may be seen soaring more frequently.

Habitat

Merlins are often found in open woodlands, grasslands, and urban areas, while Lanner Falcons prefer open savannas and semi-desert regions.

Voice

Vocalizations are not a primary distinguishing feature between these species in the field.
