[All photographs copyright, Gary Nunn 2015] – Light westerly winds this Thanksgiving Day 26 Nov 2015 so I popped down to Point La Jolla in the morning to check for bird movement on the ocean. Large groups of Pacific Loon were moving south along with a few small flocks of Surf Scoter so I stuck around. About 9:41AM Matt Sadowski spotted a small dark-colored shearwater with snappy flight manner and quite dusky feathering on the underwing. That’s interesting! I watched and photographed it through the 1000mm lens setup capturing some distant photographs. It certainly looked to my eye to have more lightweight snappy flight action than a Sooty Shearwater, making some nice fast quick arcs, and also a more uniformly dusky looking underwing compared to this species. In addition the pale chin and throat area was noticeable, it also had a more dark capped appearance, and the secondaries looked paler on the upperwing sort of forming a panel (reflection of light off fresh feathers?). For a moment initially I thought it might be a dark Pterodroma gadfly petrel because the wings were held crooked much of the flight action, again unlike Sooty Shearwater in my experience. Putting together the field marks both Matt and I feel confident this is a Short-tailed Shearwater Ardenna tenuirostris which is rarely seen from shore here in San Diego County. In fact, checking eBird, there are no validated sightings of this species anywhere in Southern California this year. Nearest reports come from the currently active seawatching program at Point Pinos, Monterey, with a small number of sightings recently. Comparable photographs to the Point La Jolla bird can be found in Brian Sullivan’s eBird checklist.
