My lawn had a moving motion to it with all the birds covering the ground the last few days as the returning sparrows and warblers look for seeds. Many of them are the White-throated Sparrow with their patch of yellow and white throat. The White-throated Sparrow and the Dark-eyed Junco have been known to occasionally mate and produce hybrids.

Some birds are less noticeable than others, and may look like another species, until something sets it apart. At first glimpse, the White-throated Sparrow may be mistaken for the common house sparrow but the whistle song of the White-throated Sparrow tells a different story. They also hop when on the ground, instead of walking,  so hard to photograph when they bounce around so much.
