I just had a red naped /red breasted sapsucker hanging out at some well established wells in my backyard (no pun intended). Completely red head, but huge white patches on the outer wing that matched online pics. I will upload my pics to eBird later, but I was curious if this was common in Santa Cruz. I usually just see the red-breasted, but there was a confirmed yellow-bellied sapsucker in my yard on the same wells a few years back. I saw one once in Yosemite maybe like 10 or 11 years ago. Fortunately the wells are on the invasive cotoneaster in my neighbor's yard.
