ALBACORE TRIP REPORT: SEP 13, 2014

THE BEST JAEGER SCHOOL

64 JAEGERS & 2 SOUTH POLAR SKUAS, Oh My!

OUR 2015 ALBACORE TRIP  SEPT. 12
Monterey seabirds and marine mammals delighted and thrilled folks on the Shearwater Journeys' offshore albacore trip on September 13, 2014. Because the marine forecast was excellent, we headed south toward the Sur Canyon area. Highlights were non-stop: BROWN BOOBY, MANX SHEARWATER, SCRIPPS'S MURRELETS, SABINE'S GULLS, ARCTIC TERNS, BLUE WHALES, BAIRDS' BEAKED WHALES, GRAND SLAM on the JAEGERS: POMARINE, PARASITIC, and LONG-TAILED putting on an amazing show to the delight of all! The albacore trip is a specialty trip, being 12 hours long, as compared to the classic trip which is 7.5 hours long. IF you can only make one trip in Monterey, make it this one! Shearwater Journeys is the only company that offers this trip. 
At daybreak, already many miles offshore, the first bird was a RED-NECKED PHALAROPE, above.
It was also the last seabird of the day when we returned to the dock!

LONG-TAILED JAEGER, above, is often a very difficult to find nearshore, and even more difficult to photograph. Read on!


The best reading from Terrafin, a service I subscribe to that provides SEA SURFACE TEMPERATURES, above, was a blended map due to fog. The warm water 'blob' was present everywhere. This is not necessarily good for birding. Finding the edges of where cooler water meets the warmer water is important for seabirding.

Storm-petrels have been largely absent all fall, probably feeding at some extremely distant location not reached by daily pelagic trips. However, this BLACK STORM-PETREL, above offered some nice views. A handful of endangered ASHY STORM-PETRELS allowed for flight comparisons.

One indication of exactly how flat-calm the seas were is the number of NORTHERN FUR SEALS that were observed (8). This fur seal is resting in what is called, "the jug handle position," locking its hind flipper with its fore flipper. 
A handful of LONG-BEAKED COMMON DOLPHINS entertained us. This species is usually associated with offshore warm water. 
We were definitely very lucky to find two BLUE WHALES because all of the blue whales along the nearshore of the central coast of California departed about July 10th, when the krill disappeared! Blue whales are the largest animals to have ever lived on Earth, larger than any of the dinosaurs. It is difficult to grasp their size most of the time — three school buses long! Above, Beth Hamel beautifully captures the steely-blue colored flank and small dorsal fin.
The blow of a BLUE WHALE shoots some 30 feet high in the sky! 
I once saw a peregrine falcon flying through the blow of a blue whale!
Some 29 miles offshore, a BROWN BOOBY made a pass at our stern!
This fall brown boobies staged a major invasion along the coast with many reports continuing into winter/spring 2015. 
Remarkably, only one BULLER'S SHEARWATER was found. Typically, we find hundreds on the albacore trip. The masses of them must have been feeding at a temperature break that we could not reach on a one day trip. Still, one is better than none!
And the chase is on. And, on. And on!
The word "jaeger" is of German origin, meaning "hunter."
We certainly did see a lot of them hunting!
The larger jaegers, pomarines, especially, seem to chase SABINE'S GULLS. 
LONG-TAILED JAEGER, below. 
Long-tailed Jaegers often chase ARCTIC TERNS, below. 

LONG-TAILED JAEGER, subadult, above. 
Sub-adult PARASITIC JAEGER, above. 
POMARINE JAEGER, adult male, above. 
Males are smaller than females. 
A number of low, bushy blows are spied, and I'm sure we have BAIRD'S BEAKED WHALES! 
This is a major specialty of trips that venture far offshore! 
In the images, above and below, Beth Hamel captures the "beaks" of these whales. 
Like all odontocetes, these toothed whales have a single blowhole, visible in the image, below. 
Females can reach 40 feet in length. Army brown in coloration, they show many scars. 
BAIRD'S BEAKED WHALES, Berardius bairdii, travel in tight groups, blowing and diving synchronously, and often touching each other with their beaks. 
They could be capable of diving deeper than 9000 feet. 
They eat squid and deep dwelling fish. Indeed, we came across the remains of their food which was being consumed by BLACK-FOOTED ALBATROSSES, in the image, below!

Nearly a constant companion, PINK-FOOTED SHEARWATERS often follow in the wake of our vessel. 
A Grand Prize of any albacore trip is murrelets, especially sitting on the water for great views! 
This SCRIPPS'S MURRELET was one of two that were positively identified. 

It has been a big fall for the BY-THE-WIND-SAILORS, Velella velella, above.

Many thanks to the wonderful group of birders who joined us on this day who hailed from England, Texas, Illinois, Maryland, Michigan, Washington, Georgia, Minnesota, and California. It was a gorgeous day at sea. Leading this offshore trip were: Scott Terrill, Linda Terrill, Jennifer Green, and Debi Shearwater. 

The complete species list follows. All records are for Monterey County. SST's ranged from 63F to 60-59F. Beaufort .5 to 1.5, glassy seas, excellent conditions. We went south to the "weenie."

HALF MOON BAY PELAGIC TRIP JUMPING WITH MARINE LIFE! AUGUST 16, 2014

Shearwater Journeys's twelve hour August 16 pelagic seabirding trip from Half Moon Bay was filled with non-stop marine life action, from the smallest animals such as PTEROPODS to the a top predator, a SALMON SHARK. Seabirding was superb with highlights of BULLER'S and BLACK-VENTED SHEARWATERS; WILSON'S, ASHY and BLACK STORM-PETRELS; SOUTH POLAR SKUAS; one SABINE'S GULL; SCRIPPS'S MURRELETS and TUFTED PUFFINS! The appearance of three species of somewhat "tropical"marine mammals was very extraordinary: a school of LONG-BEAKED COMMON DOLPHINS and a DWARF/PYGMY SPERM WHALE and a presumed offshore BOTTLENOSE DOLPHIN. The pinniped list was extensive: CALIFORNIA and STELLER'S SEA LIONS; NORTHERN FUR SEALS; NORTHERN ELEPHANT SEAL, and HARBOR SEAL. Todd McGrath was intent on keeping a jelly list which included: EGG YOLK JELLY, MOON JELLY, SEA NETTLE, LION'S MANE JELLY, PURPLE-STRIPED JELLY and BY-THE-WIND-SAILORS. There was something to look at all day long, for twelve solid hours! 
We spent most of the day along the 100 Fathom Line, or edge of the Continental Shelf. It was very interesting that the storm-petrels were found along this contour because I haven't seen them in such shallow water for a great many decades. Usually, I have found them along the 500-800 fathom contour.  Sea Surface Temperatures (SST's) ranged from 61 to 63 F. 
PTEROPOD, above. From the 50 Fathom line to 100 Fathoms, the ocean was filled with plankton, including pteropods, salps and many jellies. Only a week ago, this was not the case. A pteropod is a gastropod or snail with a reduced or, no shell. They are also known as "sea butterflies."
SALPS in Debi's hand.

Salps form long, stringy colonies. They are barrel shaped planktonic tunicates. They move by contracting and pumping water through their gelatinous bodies. The jet propulsion of the slap is one of the most efficient in the animal kingdom. They have a complicated life cycle. We saw the part of the cycle that is called a blastozooid. They feed on phytoplankton — and, there seemed to be a lot of that around!
 A solitary HUMPBACK WHALE was just outside of the harbor. 
Image by Scott Terrill
Humpback Whales are commonly found during fall along our coast. However, the sighting of a DWARF/PYGMY SPERM WHALE is most unusual! In nearly forty years of trips off the California coast, I have only seen this animal once before. Only two of us on board saw it, myself and Scott Terrill. There are two species: Pygmy Sperm Whale and Dwarf Sperm Whale, both in the genus Kogia. I had five views of this unique animal at the surface, but could not be certain which species it was. We were on the Continental Shelf which is the presumed habitat of Pygmy Sperm Whale, but what I saw looked more like Dwarf Sperm Whale. I've seen both species on long ocean voyages in the Atlantic and Pacific, but this species was not on my radar! Very little is known about either species. And, of course, it will come as no surprise to anyone that this animal feeds on SQUID! I've been saying all weekend: "IT'S ALL ABOUT FOOD!" Something to look for on future trips this session!

This species was another surprise, along with a "presumed" offshore BOTTLENOSE DOLPHIN. (I would have preferred a closer view of that single dolphin, though). Long-beaked Common Dolphins are the prototypical dolphin in shape and proportions. The beak is long compared to the Short-beaked Common Dolphin, with Long-beaks having more sharp, pointed conical teeth. They have a bold, hourglass pattern on their flanks and are very gregarious. Long-beaked Dolphins are associated more with warmer and shallower water than the Short-beaked Dolphins. They almost always ride the bow, putting on a good show!

OCEAN SUNFISH, Mola mola, below, have been numerous.
It has been a great fall for viewing the darling Ocean Sunfish, reported to be the heaviest bony fish in the world. Indeed, some that we have seen have topped 400 pounds, while the smaller ones we call "silver dollars." They feed primarily on jellyfish. Our Monterey captain saw them eating BY-THE-WIND-SAILORS earlier this summer! In turn, the sunfish is predated by sea lions, killer whales and sharks.

RISSO'S DOLPHINS which we are finding on almost every trip these days, both Monterey and Half Moon Bay, owing to the presence abundant squid which they feed on.

A SOUTH POLAR SKUA which our captain deftly brought the boat along side while it was sitting on the water, giving everyone great views!

A HY HEERMAN'S GULL, below, apparently a rarity this fall.

A surprise at the end of the day — a ten foot SALMON SHARK!
An apex predator in the Pacific Ocean, the Salmon Shark feeds on salmon, squid, sablefish and herring. Lots of squid have been around, as previously reported, and fishermen are still catching salmon just outside of Pillar Point Harbor, Half Moon Bay. 
The fin shape and gray colored body with black spots are field marks for this amazing shark.

The shark swam around our vessel for a good five minutes. 
Salmon Sharks have been followed by tagging and revealed some amazing results.
