Also known as Myrtle Warbler (which this one is).
These are around in Winter and are migrating now.
This one was high up in the Elm tree, but I got a couple photos that are good enough quality to ID it.
Out here today are still Pine Siskins, Pine Warblers, and Chipping Sparrows that have not yet left. An Indigo Bunting is here who has migrated in. Good fun in the yard.
