The dodo, Raphus cucullatus (Aves, Columbidae), has become one of the
most famous birds in the world, a true icon of extinction. Known from a few
contemporary illustrations and accounts, probably more has been written
about it than any other species, yet we know practically nothing about the
bird in life. Recent excavations on Mauritius are now revealing the ecology
and habitat of this iconic bird, and providing new information as to why it
was so vulnerable to human interference.
Discovery of the Mascarenes
The Mascarene Islands, comprising Mauritius, Réun-
ion and Rodrigues, are isolated volcanic islands situ-
ated in the south-western Indian Ocean (Fig. 1). They
lie approximately 665 km east of Madagascar, the
nearest large land mass. It was Arab traders who
first discovered the Mascarene Islands during the
thirteenth century, followed by the Portuguese in
the sixteenth century, but there is no evidence that
either the Arabs or Portuguese settled there. Mauri-
tius was claimed for the Netherlands by the Dutch
East India Company (VOC) in September 1598, and
was used thereafter as a port of call for provision-
ing and careening ships, including those from other
European maritime nations. During this time, vague
accounts were made in ships’ logs and journals about
the original fauna, some of which described the dodo.
Although inadequate, these accounts have proved in-
valuable in helping determine the faunal composition
of Mauritius before it was irreversibly destroyed by
humans and their commensal animals. It was dur-
ing the century of Dutch occupation that the dodo
became extinct.
Written and pictorial evidence
It was VOC company policy that daily records were
kept concerning all aspects of the voyages. These in-
cluded topographical maps, safe shipping routes and
potential harbours, as well as written descriptions.
Just occasionally, a member of the fleet would de-
scribe or illustrate the animals he encountered. Upon
the return of the fleets, the journals became impor-
tant source material for artists, scientists and book
publishers (Fig. 2). These publications, which were
regularly expanded and illustrated long after the voy-
age itself, became the source material for scholarly
study, but were also plagiarized on numerous occa-
sions. This is why the contemporary accounts and
illustrations of the dodo are often contradictory, and
have resulted in a wealth of scientific myths and mis-
conceptions.
Transportation of specimens
Besides the transportation of trade goods from the
Far East, exotic animals were also brought back to
Europe as novelties. These curiosities, many new to
