Schieferfalke Falco concolor

Slim, long-winged, long-tailed falcon that is built for long-distance migration. Adults are all gray, while juveniles have pale, spotted underparts. Breeds on cliffs along the coast or in the desert. During migration and winter, spends most of its time on the wing, and can be seen over any habitat. Quite social, and often seen in loose flocks of dozens or more. Adult is very similar to the dark-morph adult Eleanora’s Falcon, but Sooty is paler gray. Immatures also very similar, but immature Sooty has an unbarred tail without a rufous tip. Much longer wings and tail than Peregrine Falcon. Larger and lankier than other falcons.
