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

  • Leach’s/Townsend’s Storm-Petrel:  3
  • 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.

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.

Offshore totals for the day were:

Cinnamon Teal  4

Red-necked Phalarope  50

Red Phalarope  4

Pomarine Jaeger  1

11 September 2022

The San Diego pelagic trip on Sunday, 11 Sep, aboard “Legacy” and sponsored by Buena Vista Audubon Society was…..awesome! Well, certainly three hours of it in the morning were extra awesome. Sea conditions were surprisingly pleasant, post-“Hurricane KAY,” all day. Just several miles out to sea we had a very cooperative sitting RED-BILLED TROPICBIRD that allowed us to get quite close. That was followed by two separate sub-adult Nazca Boobies. Then, as we crossed the San Diego Trough in quick succession we had a BLUE-FOOTED BOOBY circle the boat–a casual visitor to coastal California–and then a casual, light-morph WEDGE-TAILED SHEARWATER–the third record for San Diego County and perhaps only around ten or so records for the state–which flew around and in front of the boat for an extended period. This was a new California bird for everyone on the boat except for two folks. Not too long after that an adult Nazca Booby appeared, followed immediately by a Red-footed Booby! Later on we added a Masked/Nazca Booby (photos will be examined further) and another Nazca! Also present were Least Storm-Petrels for much of the trip, a few exceedingly close to the boat, as well as a small-to-moderate number of Townsend’s and Leach’s Storm-Petrels and one Ashy Storm-Petrel. And then to cap it all off at the very end, there was an adult male MAGNIFICENT FRIGATEBIRD circling around near the dock when we returned!! Perhaps the strangest sight of the day, in a depraved sort of way, was the flock of five Killdeer that flew past the boat several miles offshore–not your typical “pelagic” species. We also had good looks at a Guadalupe Fur Seal.

Offshore totals for the day were as follows:

KILLDEER  5  (!!!)

Red-necked Phalarope  140

Red Phalarope  17

Pomarine Jaeger  6

Parasitic Jaeger  3

Cassin’s Auklet  1

Craveri’s Murrelet  3

Heermann’s Gull  8

Western Gull  400

California Gull  1

Common Tern  120  (good count)

Elegant Tern  125

RED-BILLED TROPICBIRD  1  (3.8 mi off n. Point Loma)

Townsend’s Storm-Petrel  8

Leach’s/Townsend’s Storm-Petrel  27

Ashy Storm-Petrel  1

Black Storm-Petrel  55  (low)

Least Storm-Petrel  95  (along entire route)

WEDGE-TAILED SHEARWATER  1  (21.8 to 21.3 mi W of tip of Point Loma)

Pink-footed Shearwater  48

Brown Booby  7

RED-FOOTED BOOBY  1  (23.4 mi W of tip of Point Loma)

Brandt’s Cormorant 17

13 August 2022

The San Diego pelagic trip on Saturday, 13 August, aboard “Legacy” and sponsored by Buena Vista Audubon Society visited the 9-Mile & 30-Mile Banks, San Diego Trough, and “The Corner,” out to the edge of San Diego County waters. The seas were moderate on the way out, but lightened the remainder of the day. It was a very good trip, with some of the highlights being a well-seen Cook’s Petrel at The Corner, at least three different Black-footed Albatrosses (The Corner, 30-Mile Bank, w. SD Trough), 3 or 4 Least Storm-Petrels (The Corner & 30-Mile), 1 Ashy, 12+ Townsend’s & 22+ Leach’s Storm-Petrels (some of which were closer to shore than usual, as close as the 9-Mile Bank), 11 Craveri’s Murrelets, 5 Long-tailed Jaegers, 9 Sabine’s Gulls, 1 Arctic Tern (30-Mile), a good count of 50 Common Terns, 3 Northern Fulmars (very rare at this time of year), and 9 Brown Boobies.

And we are on a roll!!!  For the THIRD scheduled pelagic trip in a row (June, July, August), despite our attempts to sift through flocks of Black-vented Shearwaters in hopes of finding a very rare Manx Shearwater, but to no avail, a Manx has indeed been found after the conclusion of the trip via folks looking carefully at their photos. This trip’s installment of the saga is courtesy of Barbara Wise, who studied her many trip photos from yesterday and found a Manx sitting in a large flock of Black-venteds in the eastern San Diego Trough.

16 July 2022

The 16 July San Diego pelagic trip out to the 30-Mile Bank/The Corner area, aboard “Legacy” and sponsored by Buena Vista Audubon Society, was blessed with light seas and some good birds. The star of the show was the extremely cooperative Guadalupe Murrelet halfway across the San Diego Trough (32.626, -117.584; 19.9 miles W of tip Point Loma)–a species that is only casual within San Diego County waters. Only brief or distant views were had of a Red-footed Booby only a mile off Ocean Beach, of a Townsend’s Storm-Petrel along the outer edge of the 9-Mile Bank, and of a Black Tern in the San Diego Trough. The smooth seas were great for alcids, and we also had a super total of 77 Craveri’s Murrelets, which is possibly a new one-day record for the county (previous high 68?), 35 Cassin’s Auklets, and 2 Common Murres. Other highlights included two immature Long-tailed Jaegers at the 30-Mile Bank/The Corner, a falling-apart Northern Fulmar, two Sabine’s Gulls, and small numbers of both Leach’s (dark-rumped) and Ashy Storm-Petrels. Just after the trip, Nick Thorpe went through all his photos and discovered a MANX SHEARWATER he had photo’d at 9:22AM. At that time, we were down fairly close to the border and near the 9-Mile Bank. Congratulations to Nick for deducing the Manx from his photos, and lumps of coal to all the rest of us who missed this bird when it flew by…
