skiferfalk Falco ardosiaceus

Medium-sized gray falcon with bright yellow eye-ring and base of the bill. Quite plain, but does show barring on the wings in flight. Found in open woodland and savanna, often in areas with palms. Call is a repeated, vibrating “krrrr.” Similar to Sooty Falcon, but separated by much shorter barred wings and boxy head. Also similar to Dickinson’s Kestrel, but easily distinguished by uniformly gray plumage. Other small falcons do not have gray underparts.
