The juv. sparrow looks to be a Chipping Sparrow as the browns are to warm in color for Timberline/Brewer's type. The color on the head is also "too warm" of brown.
The vireo looks most like a Warbling Vireo. A Phil. Vireo in fall is usually more yellow than what I can see in the photo on the under parts.
