Bryan,
I think your gnatcatcher is a Blue-gray that has molted some tail feathers.
I can't see any reason that the hummingbird is a somewhat worn male
Black-chinned Hummer.

gnatcatcher ID (photos)
Birded South Llano River State Park today and ran into a couple
of birds that we were uncertain about. The first is a gnatcatcher, that I
assume is probably just some weird Blue-gray Gnatcatcher (juvenile?). The
undertail was entirely black, but I feel like it's missing some feathers or
something. The tail didn't have a full appearance, and doesn't really match
the patterning of a Black-tailed, either. In fact, there's almost no
pattern at all, just sheer black (which is not just backlighting, the
appearance in the photos is true to life). It appears to have a bit of an
eye ring and be a little too blue for a Black-tailed, imo, but I'm not
particularly familiar with them, to be honest (just going off Sibley's). I
don't really know what to make of the broad vs. narrow white tertial edges
that they mention in Sibley's, either. The photos aren't particularly good
for that field mark.

The next is a hummingbird that seems like possibly a Calliope
(apparent white in the gorget), but can't really rule out any of the
Selasphorus, either. Obviously, it's very buffy/creamy, and in spots that
seem weird (to me, at least). The lighting was awful, so our looks (and my
photos) were pretty bad. Am I just way off and it's an Archilochus?
