For this question, the ambiguity is in “bird.” In modern day birds, they don’t have teeth, and that would be the right answer. However, Archaeopteryx, a bird that has existed 150 million years ago had teeth.



Nothing ambiguous about the question:

"Similar in size and shape to a European Magpie, it bore broad, rounded wings and a long tail. Archaeopteryx could grow to about half a meter, or 1.6 feet in length.
