What do people think who pass by us as we excitedly gesticulate, darting back and forth, peering up into the trees with our cameras aimed, and "swishing" all at the same time???
Usually they are near the top of the trees, so I never even realized they have a yellowish green circle on their back.
Black-throated Green Warbler
God's creation - the colors, the variety even amongst these five warblers- is truly spectacular!
