18 May 2024

The San Diego pelagic trip on 18 May sponsored by Buena Vista Audubon Society aboard “Legacy” out of Mission Bay went out to the 9-Mile Bank, San Diego Trough, 30-Mile Bank, and “The Corner.” Ocean conditions were excellent, with light seas and a high marine overcast all morning.

Especially impressive totals included the 20 Blue Whales, 115 Scripps’s Murrelets, 3000 Sooty Shearwaters (including one bird with a fully white head and neck), and 6 Brown Boobies. The two Common Murres were scarce and getting late.

30 September 2023

The San Diego pelagic trip on 30 September aboard “Legacy” and sponsored by Buena Vista Audubon Society ventured out to the Nine-Mile and 30-Mile Banks. Weather was generally fine, despite some forecasts to the contrary, with fairly low swell, light chop, and dry skies. The slight chop, however, did make it difficult to spot alcids on the water, so all murrelets and auklets were seen only in flight. Highlights included a well-seen one-year-old Masked/Nazca Booby at the Nine-Mile Bank, a young age which is typically difficult to identify to species, but we’ll work on photos, just in case. Good numbers of storm-petrels on the 30-Mile Bank included approx. 300 Leasts, an Ashy, a briefly seen dark-rumped Townsend’s, and good numbers of Blacks.

Totals for the day once offshore were:

  • Red-necked Phalarope  26
  • Red Phalarope  2
  • Pomarine Jaeger  5
  • Parasitic Jaeger  5
  • jaeger sp.  2
  • Craveri’s Murrelet  2
  • murrelet sp.  8
  • Cassin’s Auklet  8
  • Sabine’s Gull  3
  • Heermann’s Gull  11
  • Western Gull  250
  • California Gull  1
  • Common Tern  20
  • Forster’s Tern  1  (7-1/4 mi off Ocean Beach, farther offshore than usual)
  • Elegant Tern  20
  • Common Loon  1
  • Townsend’s Storm-Petrel  1  (dark rumped; 30-Mile)
  • Leach’s/Townsend’s Storm-Petrel  1  (white-rumped; 30-Mile)
  • Ashy Storm-Petrel  1  (30-Mile; scarce in fall)
  • Black Storm-Petrel  1400  (including several rafts)
  • Least Storm-Petrel  300  (30-Mile; good count)
  • Pink-footed Shearwater  35
  • Black-vented Shearwater  250
  • Masked/Nazca Booby  1  (upper Nine-Mile Bank; one-year old)
  • Brown Booby  2

10 September 2023

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.

Totals for the day once offshore were:

  • Whimbrel  3
  • Red-necked Phalarope  150
  • Pomarine Jaeger  7
  • Parasitic Jaeger  6
  • jaeger sp.  4
  • Craveri’s Murrelet  6  (w. SD Trough/30-Mile Bank)
  • Cassin’s Auklet  5
  • small alcid sp.  5
  • Sabine’s Gull  8
  • Heermann’s Gull  12

26 August 2023

The San Diego 11-hour pelagic trip on 26 August aboard “Legacy” and sponsored by Buena Vista Audubon Society made the usual route out to the Nine-Mile and 30-Mile Banks and “The Corner”–out to about 34 miles offshore. A mass of thousands of feeding shearwaters and other birds only 5-6 miles offshore was spectacular. As we neared that concentration, a light-morph Wedge-tailed Shearwater flew right up the side of the boat, establishing the fourth record for San Diego County of this casual visitor to California waters. The same mass of birds also included an adult or near adult Nazca Booby. Farther offshore was much quieter, but we did find a few Leach’s and single Townsend’s & Least Storm-Petrels, plus another adult booby that was just a bit too far to safely ID as either Nazca or Masked.

Totals for the day, once about a mile offshore were:

  • Whimbrel:  25

  • Black Storm-Petrel:  245
  • Least Storm-Petrel: 1  (Nine-Mile Bank)
  • Northern Fulmar: 1  (Nine-Mile Bank; rare in summer)
  • WEDGE-TAILED SHEARWATER: 1  (ca. 5-1/2 mi W of Ocean Beach; 32.75, -117.35)
  • Sooty Shearwater:  450  (good count for this time of year)
  • Pink-footed Shearwater:  4500  (probably record high count for SD County)
  • Black-vented Shearwater:  5000
  • NAZCA BOOBY:  1  (adult ca. 5-1/2 miles off Mission Bay; excellent views)
  • Nazca/Masked Booby:  1  (adult, just slightly too far to ID; 30-Mile Bank)
  • Brown Booby:  5
  • Brandt’s Cormorant:  3
  • Double-crested Cormorant:  2
  • Brown Pelican:  630
  • Brown-headed Cowbird: 2

3 June 2023

The Saturday, June 3rd, pelagic trip aboard “Legacy” and sponsored by Buena Vista Audubon Society traveled out to the outer edge of San Diego County waters at the 30-Mile Bank and “The Corner,” via the 9-Mile Bank and San Diego Trough. It was certainly a record day for Cook’s Petrels, many seen very well both in flight and sitting on the water, with the day’s total of 56 birds setting a new record for San Diego County waters. It also included two birds record close to shore, with one on the 9-Mile Bank some 11.5 miles off Point Loma and another just inside the 9-Mile Bank only 10 miles from Point Loma. Other highlights included 7 Arctic Terns (very rare in spring), 7 Leach’s Storm-Petrels (good count for this early in the season), 3 Craveri’s Murrelets, a rare-in-June Northern Fulmar, and 14 Ashy Storm-Petrels. Still good numbers of Scripps’s Murrelets present, two Brown Boobies, and single getting-late adult Sabine’s Gull and adult Pomarine Jaeger. Also a number of Blue Whales and one Fin Whale.

The San Diego pelagic trip on Sunday, May 7th, aboard “Legacy” and sponsored by Buena Vista Audubon Society, traveled out via the 9-Mile Bank to the edge of county waters at the 30-Mile Bank and “The Corner.” Seas were moderate on the way out and lightened up as the day went on and became quite a pleasant ride.

The half-day (6-hour) San Diego pelagic trip on Saturday morning, 22 October, sailed out to the 9-Mile Bank and edge of the San Diego Trough. Sponsored by Buena Vista Audubon Society aboard the “Legacy,” it took place under pleasant sea conditions. The highlights were certainly the boobies, with a very cooperative sub-adult Nazca Booby next to the boat some 5.4 miles off Point Loma, a Red-footed Booby some 10.3 miles west of the tip of Point Loma, and a very high count of 37 Brown Boobies, which included two mid-sized flocks of up to 10 birds each. Another highlight was the good views of a Hammerhead Shark, perhaps especially surprising this late in the season.

Surf Scoter: 15

Red Phalarope:  4

Pomarine Jaeger:  4

Parasitic Jaeger:  1

jaeger sp.:  1

1 October 2022

The San Diego pelagic trip on Saturday, October 1st aboard “Legacy” and sponsored by Buena Vista Audubon Society took place under very pleasant conditions of light seas and high overcast. We ventured offshore to the Nine-Mile Bank, San Diego Trough, 30-Mile Bank, and The Corner. Highlights of the day certainly involved the booby show, with excellent looks at three species. A Red-footed Booby repeatedly approached and circled the boast, and it even briefly landed on the wheelhouse. An adult or near-adult Nazca Booby flew right over the boat. An additional adult Nazca was seen later in the trip at great distance, and a Masked/Nazca was also seen at some distance. Brown Boobies appeared repeatedly during the day and totaled some 11 individuals. Another highlight of the trip were the good numbers of scattered Least Storm-Petrels seen over large parts of the route.
