Is this a Fairy Wren

Hi All,

I took my new lens on it's first field trip to Organ Pipes National Park today, and met a few new friends.

I think this is wren or fantail of some kind, but have no real idea, I was hope one of you more experienced people could help.

For a relative novice like me these guys were very hard to shoot, this is about the best I managed.

Cheers,
Denis.
