The Western Meadowlark is very similar in plumage to the Eastern Meadowlark although has very different song patterns. Their ranges don't often overlap -- except in Southern Arizona where the occasional Eastern Meadowlark can be found.
It forages mostly on the ground looking for insects and seeds -- even digging in the ground with its bill. Insects include beetles, grasshoppers, crickets, caterpillars, ants, bugs, and spiders. In the fall and winter it eats more seeds and grains.
