Yesterday, August 24, was my first time leading on a Shearwater Journeys trip for the year, and it turned out to be a great day to be on the water. We had the calmest seas I've experienced in years and a very nice marine layer that lingered late into the morning. On the way back into the harbor at Monterey, about a mile or less off Pt. Pinos, I picked out a distant, but clearly very large Sulid flying over a feeding flock; the size and dark and light patterning quickly narrowed the options down to a couple species...Masked or Nazca Booby! Luckily Captain Tinker was willing to go check it out even though it was getting late, and we managed to stay on the bird and get to it quickly. The boob made several close passes, flying directly over the boat, and even did some plunge diving off the bow! On at least one occasion, it did successfully grab a fish.
This was one of those rare and special occasions where we had talked about our chances of finding a specific high quality rarity and had those hopes come to fruition. We were on the lookout for rare boobies all day, as it has been an excellent year for finding several species from San Diego north to Monterey, specifically Red-footed, Masked and Nazca. Incredibly, 6 species of Sulids have already been reported in California this year! It just seemed like there was bound to be one of these birds around.
However, the jury is still out on what species this is, or if it can safely be identified to species...immature Masked and Nazca (both Bird Police species in California) are notoriously hard to tell apart, and I have no experience with Masked in this plumage, or with Nazca whatsoever. If you have some familiarity separating these two species, I'm very interested to hear what you have to say. All photos in today's post can be viewed at full size, so please feel free to double click on images and comment away.
Below is a crop from the above shot, the best I was able to manage of the uppertail. Lots of molt going on.
And here is a garbage photo that at least does show the overall uppertail pattern again.
Whether Masked Booby, Nazca Booby, or the dreaded Slash Booby, I'm stoked.
