Lanner Falcon vs Saker Falcon

In short

The Lanner Falcon and Saker Falcon can be challenging to differentiate, but key distinctions lie in their structure and plumage. The Lanner Falcon typically has a more slender build and a distinct facial pattern, while the Saker Falcon is bulkier with a more uniform plumage. Observing these differences in the field can aid in accurate identification.

Identification tips

• Look for the Lanner Falcon's more slender build and distinct facial markings.
• Note the Saker Falcon's bulkier size and more uniform plumage.
• Consider the habitat: Lanner Falcons are more common in savannas, while Saker Falcons prefer steppe regions.
• Use binoculars to observe the facial pattern and overall plumage tone for accurate identification.
