Gruiform
White-naped crane (Grus vipio).
Within the order Gruiformes, two specific species are noted for causing crop damage in their respective regions:
- Sandhill crane (Grus canadensis): During their autumn migration, these birds descend upon grainfields in the Canadian prairies, where they can cause some crop damage.1
- Brolga (Grus rubicundus): Also known as the Australian crane, this species causes similar crop damage in Queensland, Australia.1
Aside from these instances, gruiform birds generally have a negligible impact on human interests due to their relative scarcity.1
