The hiragana word below is washi, which you may be familiar with as the word for paper. However, in this case, it is also the word for eagle. There is a kanji ideogram that specifically means eagle, but it requires 23 strokes. It seemed too much to inflict on you for the last class of the semester.
Here is a relatively simple sketch of a bald eagle for practice.
