Observation details

adult, still in mostly alternate plumage, sitting on water near two MAMU that I was photographing so ended up having photographed the LBMU before even looking at it to realize what it was, slightly but noticeably larger than the MAMU, dark on side of neck where MAMU shows a collar so had head patterning like a "Xantus's" Murrelet, had the pale spots on the back of the head, white throat, speckling further down though belly mostly dark, eye slightly outlined in white unlike MAMU. After watching on the water it flew off to the south, went over to the area where it had landed and didn't see, though after a short time spotted it flying toward the boat when it gave a close fly-by before circling around to the south and flying down to Cape Alava where I lost it after watching it in flight for 30+ seconds.
