What is an animal?

This may seem too obvious for comment, but some confusion arises regarding references to birds.

Note that all birds are animals - but not all animals are birds.

Here we use the term "animal" in the biologist's inclusive sense - meaning all birds, mammals, reptiles, and amphibians.

(By definition we would also include insects, crustaceans, and a number of other life forms. But we don't see many of those in our Hospital!)
