Von der Decken's hornbill (Tockus deckeni) is a hornbill found in East Africa, especially to the east of the East African Rift, from Ethiopia south to Tanzania. It is found mainly in thorn scrub and similar arid habitats. Jackson's hornbill is often treated as a subspecies of it. It was named after the German explorer Baron Karl Klaus von der Decken (1833–1865). Wikipedia →

Restricted to human observations from 2019 onwards — the same kind of record and the same period the probabilities on this page are built from, so collar-tracking studies, camera-trap arrays and museum specimens are excluded. Around Santa Rosa that removes 5,924 GPS fixes from a handful of tagged jaguars.
