carolina wren or bewicks wren?

I live in the Hot dry Hill country smack dab in the middle of Texas. On my apartment balcony, i have hanging baskets with plants. Ive been watching a bird make a nest, a dome shapped nest with a side entrance out of twigs. the babies have hatched and i have figured out the bird is either a carolina wren or a bewicks wren. ive googled the descriptions and still cant tell which is bird it is. shes really fast and i cant get a good look at the tail cus thats how the net says to tell them apart. the one thing i can says is that she is quite red. when she fys off shes a reddish brown color, so much so that i used to think she was a female cardnale. does anyone know which of the 2 types or wrens a redder and smaller? also which is more common around austin texas? are tehir nesting habits different cus she seems very happy with her nest in my hanging plant, she doesnt even mind me out watering.

Here one of my fav. websites. It could be the Carolina
