New bird sighting!!! Wren?

I had just sat down in the yard, with both dogs, when a teeny bird appeared on the fence.  I didn't get a good look, as it was bordering on dusk and I didn't have binoculars handy, but the tail was up, which makes me think maybe some kind of wren?  (I haven't the faintest though)  Most definitely wasn't a goldfinch though.  Had a different call too.

Lingered on the fence for a moment, then clung onto the brick wall of the neighbour's house while deciding me and the dogs weren't worth trying to brave, and flew off.
