Birding photo backlog: bushtit vs Bewick's wren

I'm down with some nasty bug that's going around so when I'm not sleeping, coughing, sneezing or staring into space, I'm doing small things on my computer.  Today's small thing is processing some of my bird photo backlog.

These are from March 28.  Mischa and I were at Squalicum Beach Park and when we spotted this little grey-brown bird,  our first thought was a bushtit.  Breeding season is pretty much the only time you get to see bushtits by themselves as they're usually tumbling through the air in groups of a dozen or more.  So I got my camera up to see if he'd sit still for a pic.  And I got this shot.

Then he decided to really make his presence known, tilted his head back and started singing.  That's when I saw the distinctive big white eyebrow and realized this was a Bewick's Wren.

I've never before considered these 2 birds to look much alike so this was a learning experience.
