San Diego pelagic 10 Sep: 7 Nazca & Masked/Nazca Boobies, Craveri’s, Least and Townsend’s

4:56 am

The pelagic trip off San Diego on Sunday, 10 September, sponsored by Buena Vista Audubon Society and aboard “Legacy,” visited nearshore waters and out to the 9-Mile and 30-Mile Banks. Sea conditions ended up being appreciably better than had been forecast, with only mostly light winds and light to moderate swell. As has been the case the past few weeks, the largest concentration of birds (especially shearwaters) was inshore. Highlights certainly included the Nazca Booby show, with a total of FIVE adult and near-adult birds scattered between 6 miles offshore out to the 30-Mile Bank, as well as 2 much younger birds that are currently being left as Masked/Nazca Boobies but we’ll see if photo analysis and discussion in the near future can raise either bird to “full species rank.” In comparison, “only” 2 Brown Boobies were seen. We also had pairs of Craveri’s Murrelets, as well as brief or rather distant views of 1 white-rumped Townsend’s and several Least Storm-Petrels, plus better views of at least 8 “Chapman’s” Leach’s Storm-Petrels.
