re: Identify this songbird

I appreciate yall's response. My reference is George Lowrery's Louisiana Birds.

The birds were observed in Lake Charles. The male did have some areas of white on the face and they both have brownish upper bodies and lighter bellies.
The beaks look to be light yellow. I could not see an eye ring. At this point we have eliminated all of your suggestions except for the Indigo Bunting (mottled plumage).
We will look again for them this afternoon. Thanks again.
