Similar species:
Loons are larger with longer bodies and larger, darker
bills. Horned and Eared Grebes are smaller with much shorter bills
that are never greenish-yellow. Red-necked Grebe is smaller without the bold
black and white neck pattern. The formerly conspecific Clark's Grebe is very
similar but has a bright yellow bill. The dark crown of the Western Grebe extends
below the eye, in the Clark's it is above the eye. The two species have
distinctive calls: Clark's gives a simple "kreeet" while the Western gives a
doubled note. Hybridization is known so atypical birds should be studied
well for exact bill color and face pattern.
