No, ducks are not arthropods (phylum Arthropoda) - they are chordates (phylum Chordata), along with other vertebrates like mammals, fish and amphibians. Arthropods have an exoskeleton made of chitin, like an insect or crustacean. If something has a backbone or internal skeleton, like a duck, it's a pretty sure bet it's not an arthropod.
All arthopods do not have backbones which makes all arthopods invertebrates!
