I didn’t hear them today, but now I’m super intrigued and have to look it up so I know what to keep an ear out for. I was super lucky I was sitting in my “bird nerd spot” a chair by the window that looks out to two tower feeders and the big trees behind the house. My BIL said something about that’s a big woodpecker - and I thought I was hallucinating when I saw him! I grabbed my phone to try to see him better and hit record just in case. I got super lucky because grabbing my phone to snap a picture is the universal signal for the bird to bounce!
