Wrens serving breakfast to their young

I caught a video of two Wren parents feeding their young in my backyard. I am not sure about what kind of wren these are exactly, it could be Bewick's wrens but the black throat doesn't fit. Please comment if you know which species this is. Either way, very nice to look at how they feed the tiny baby birds.

The tree is a Netleaf Hackberry (Celtis Reticulata). I love those trees, they grow in strange directions but their crowns are very thick, which is perfect for a shade tree.
