The Sooty Falcon and Saker Falcon can be distinguished by their size and plumage. The Sooty Falcon is smaller and has a uniform sooty-grey color, while the Saker Falcon is larger with a more variable plumage that often includes pale and brown tones. Observing their behavior and preferred habitats can also aid in identification.

Identification tips
