About Us

Our work with New Caledonian crows (Corvus moneduloides) is based in a large outdoor aviary near La Foa, on the mainland (Grande Terre) of New Caledonia. Most of our research involves experiments with wild birds, using a catch-release programme. Birds are brought into the aviary for a few months each year and then released back into the wild.

New Caledonian crows are unique in that they are one of a few species that make and use tools for foraging in the wild. They are also the only species besides humans that produce hook tools. New Caledonian crows’ pandanus leaf tool designs vary across populations in different geographical areas. They are therefore an ideal model species for studying tool-related cognition and cumulative cultural evolution in non-humans.


The New Caledonian Crow Lab offers research opportunities from March to August each year, for students at PhD level and researchers from other institutions. If you are interested in working with us please contact Dr Alex Taylor.
