5 Francs Bucorvus leadbeateri

Burundi's aluminum 5-franc pieces from this period were produced primarily for domestic circulation needs, but the Bucorvus leadbeateri — the Southern Ground Hornbill — makes an unlikely appearance on coinage for a country that sits outside the bird's primary range, which runs through southern and eastern Africa. The species is classified as Vulnerable by the IUCN, with populations declining sharply due to habitat loss and persecution.
