Constant Drumming

[Napper]

I've yet to find the source, a Flicker or Woodpecker is making a constant loud mid pitched drumming sound that is echoing down the  street.

I also spotted a black bird that sounds just like this guy.

Unfortunately it was tooo far to Id or get a shot of.

Could it be a Yellow Bellied Sapsucker? We have a pair that have moved into our backyard this spring for the first time. Your description of constant drumming sounds familiar.
