Uncharismatic Fact of the Day
Ostriches, kiwis, emus, and cassowaries all have one thing in common: they can't fly. For that reason alone, they must be awfully jealous of their cousins the tinamous! These birds are the only members of the infraclass Palaeognathae that are still able to fly, likely because they are quite a bit smaller and lighter than their relatives.
