I got this for Christmas along with other birding gifts, having become a nascent birdwatcher during the pandemic. My (adult) children are humoring my obsession quite gracefully. So at my backyard suet feeder in Central Virginia I have one bird that visits occasionally that I am having trouble identifying- my best guess is least flycatcher but not sure he should be here this time of year. Smaller than a sparrow, white eye-ring, two white bars on wings, and from back his black wings with white bard touch to make distinct V below grey back. Advice appreciated!
