Fox Sparrow

silent; uniform slate gray upperparts much darker than clear gray of southern Thick-billed populations; slightly enlarged lower mandible may be too big for Interior Slate-colored populations?? so perhaps this is a northern Thick-billed such as fulva which is said to be darker than southern Thick-billed????

1
Fox Sparrow (Sooty)
1
Fox Sparrow (Slate-colored)

possibly an altivagens, - bright rufous streaking on underparts, also bright rufous on wings and tail; weak singing - more jumbled notes lacking strong introductory notes of Thick-billed; call was a "smack-like" note that was unlike smack of Sooty group.- more like Slate-colored to my ear?????
