Yardbirds in the Rain

Spotted in between the rain and then sun.... and then rain.... in my backyard.

Acorn woodpecker stopping briefly among the evergreens
Bullocks Oreole stopping in at the rose bramble
Oregon Junco ground feeding
and a regular Rufous hummingbird at the feeder.

I found a partial blue eggshell. It may have been at least 1" in length when in tact with black spots.
The spots looked like much dirt or the spots that a fly leaves when it poops.
(sorry for a lack of sophisticated fly poop terminology here.)
