Possible early Common Yellowthroat; sounds slightly different to my ear but it's been all winter since I last heard them and that seems the best match. Bird was singing about 8ft up in dense thicket, not visible.
I think this is a tanager and the BirdNet app seems to agree, but suggestions welcome.
9EH and his chicks!
male; responded to pishing
Standing on the edge! Maybe he’s leaving the nest soon??
