  1. San Mateo County pelagic report - Storm Petrels! LINK
    DATE: Sep 5, 2020 @ 10:38pm, 4 year(s) ago
    Hello all, I had gone to sleep seeing 17 knot winds offshore on the computer, and wondering what things would be like in the morning. Well, winds were down to 10 knots, the sky was cloudless and suddenly what was an impending poor weather trip was going to be fine. It was better than fine, it was wonderful. As has been the norm recently Common Murres were in the harbor, and masses of Elegant Terns were fishing the anchovy that are trapped in the harbor by the millions. We headed out and the first good sign was that an Ashy Storm-Petrel was seen about 10 miles out, closer than we usually see one. In fact on the way back in, there was one 3 miles from shore, definitely a record for us. Closer to shore than we ever see them. As is typical the line of Sooty Shearwaters was out there a few miles out, and lots of Common Murres with a single remaining (they leave early) Pigeon Guillemot. As we reached greater distances from the coast we found Pink-footed Shearwaters, a few Northern Fulmar and Rhinoceros Auklet. When we arrived near the Half Moon Bay weather buoy, things picked up, more shearwaters, Black-footed albatross and a nice fly by Laysan Albatross! What we assume was the same Laysan came back and gave even better views about 40 minutes later. Wilsons Storm-Petrel caused a thrill, as one came close to the boat. Little did we know that we would see several before the days end. Most storm petrels were Ashy, but eventually we found a Black Storm-Petrel, and from there on in, they took over the show. Progressively more common on each section of the trip as we headed south. Eventually we had an hour period when we tallied over 400! Some coming in for great views. Some photos here: https://ebird.org/checklist/S73241708 The numbers do not do justice to the experience. For hours Black Storm-Petrels were constantly in view, so were many Ashy, and a few Wilsons here and there. Comparison between Ashy and Black was possible repeatedly, the bouncing flight of the long-winged Black Storm-Petrel is something we looked at so intently today, and on so many individuals that we will likely see those images as we fall asleep tonight. It was truly a great trip to really learn this species. Amazing! Another superb experience was spotting the Laysan Albatross, presumably the same one as earlier, and then Dorian Anderson yelling that he had just seen a second! Eventually, the two birds sat together at a distance from us, confirming two Laysan Albatrosses at the same time. To think that at one time it was thought that San Mateo County was not good for pelagics! It is fantastic for pelagics. Return to port surprise was a Tufted Puffin that buzzed the boat. Several Humpback Whales were enjoyed, including some lunge feeding individuals. We hope to replay some of this, with the caveat that things can change on a dime in the ocean, on Monday. Weather is forecast to be pretty calm on Monday and we can assure you that it will be cool out there. So if you want to try your luck with seabirds, and escape the heat, we have 4 spots left: https://www.alvarosadventures.com/pelagic-dates-2020.html take care, Alvaro Alvaro Jaramillo alvaro@... www.alvarosadventures.com
