I only know a few birds, but I don’t think Bewicks has white on the tail. however, it does have a white stripe over the eye, so watch for that if you see the bird again.

It doesn't look to have the perky wren tail, either. Where is this located?

North Texas

I added the Texas to original post. I thought I had put the location.

Yes the pictures you posted is how they always look to me.

This bird was farther away on the back fence and I only saw it for a few minutes.

I didn't recognize a bird with a white tip on tail like that.

I haven't seen any birds at that bird house since.

I would guess they are leucistic tail feathers. I couldn't find any with that exact configuration. eta: here is a Common Grackle with a similarly colored (leucistic) tail.

It does look like a Bewick's wren. But I am unconvinced that the light tail feathers are actually white. It appears to me to be more a lighting issue. If you look closely on the third photo, a bit of the light color is on the wing, that is not apparent in the other photos. Sunlight on part of a bird, while the remainder is in shadow, can cause a camera to go with reading the shadow portion, resulting in the brighter lit parts getting wash out. The angle of the light area is also at more of an angle and less distinct in the first photo, but straight and highly contrasting in the last two.
