THE MIXING ZONE: HALF MOON BAY PELAGIC TRIP REPORT


AUGUST 13, 2016
Shearwater Journeys' August 13, 2016 pelagic trip departing from Pillar Point, Half Moon Bay was simply put— over the top — with very exciting seabirds, whales and dolphins. Highlights included: the NORTHERN GANNET at Pillar Point; a BROWN BOOBY on a rusting barrel offshore; a GRAND SLAM: POMARINE, PARASITIC, LONG-TAILED JAEGERS & SOUTH POLAR SKUA; SABINE'S GULLS; ARCTIC TERNS; and SCRIPPS'S & CRAVERI'S MURRELETS; ASHY, WILSON'S and FORK-TAILED STORM-PETRELS. Cetacean highlights included: 11 BLUE WHALES, 4 FIN WHALES, 120 HUMPBACK WHALES; 350 PACIFIC WHITE-SIDED DOLPHINS and 4 NORTHERN RIGHT WHALE DOLPHINS.

The sea surface temperature chart showed a messy area of mixing temperatures near the weather buoy. Indeed, we tracked temperatures throughout the day as they rose from 54 F to 59.45 F. The "mixing zone" turned out to be loaded with feeding seabirds and marine mammals. 
Chart used by permission of Terrafin, a service that I subscribe to.
SCRIPPS'S MURRELET, above, was one of two that we observed. 
Two CRAVERI'S MURRELETS popped off the water almost immediately as they were called out. They did what so many murrelets do: fly over the edge of the Earth! 
At least a few lucky and fast birders saw and photographed them. 
The dusky wing-linings are a definitive ID characteristic.
An adult BROWN BOOBY was sitting on a rusty barrel well offshore.
Brown Boobies have not been as common this season as last year.


Some high flying folks were on board.

& 
SOUTH POLAR SKUA
A POMARINE (right) and PARASITIC JAEGER (left).
A great group of fun, young birders on board!
Many thanks to all of the fun participants who joined us from near and far for this almost 12 hour pelagic trip. This was an excellent day at sea for both seabirds and marine mammals. 

It takes a team to make such a day. Leaders on this trip included: PETER PYLE, STEVE TUCKER, JIM HOLMES, WILL BROOKS, and DEBI SHEARWATER. This trip was submitted to eBird following pelagic eBird protocol.

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."

MONTEREY SEABIRDS with SHEARWATER JOURNEYS

FORTY YEARS OF MONTEREY SEABIRDING
Monterey seabirds are well know, the world over, in no small thanks to Shearwater Journeys which pioneered pelagic seabirding forty years ago. For more years than any other individual person or business, Shearwater Journeys has been the single leading seabird company offering more annual departures for both novice and expert sea birders. 
More than 60,000 birders and lovers of marine life from all over the world have participated on Shearwater Journeys' trips. 
Your ocean birding trip begins right in the harbor where we may see PIGEON GUILLEMOT, BRANDT'S and PELAGIC CORMORANTS. Along the Coast Guard Jetty, we look for BLACK TURNSTONE, SURFBIRD, WANDERING TATTLER, and perhaps, the first RED-NECKED PHALAROPES in the kelp beds. Let's not forget the CALIFORNIA SEA LIONS piled up on the jetty, or the squeals of a young SEA OTTER, or an adult enjoying breakfast, below. 
Large concentrations of seabirds, sometimes in the thousands, as happened last fall with BLACK-VENTED SHEARWATERS, or more often, SOOTY SHEARWATERS, feed on the nutrient-rich waters of the Monterey Bay National Marine Sanctuary each fall. 
Above, one of thousands of BLACK-VENTED SHEARWATERS just outside the harbor on many of our 2014 fall trips. Amongst them, we found several MANX SHEARWATERS, a much rarer species, below. 
This sanctuary is contiguous with the Gulf of the Farallones and Cordell Bank National Marine Sanctuary, forming the largest protected areas in the United States. the main feature at Monterey is the huge submarine canyon which bisects the bay. This canyon is as deep as the Grand Canyon and plays a major part in the huge upwelling which brings cold, nutrient-rich waters to the surface, feeding everything from BLUE WHALES to CASSIN'S AUKLETS. Monterey Bay is one of only a few such rich marine ecosystems in the world. Many marine ecologists consider it to be the top such system. 
ANCHOVIES, below, are the stuff of life and a keystone species of this system. 
Monterey Bay is a terrific starting point for beginner sea birders. The bay is half-moon shaped lending protection from the prevailing northwest winds. This means that we generally have very good to excellent marring weather conditions, especially during fall migration. Veteran sea birders know that Monterey Bay can turn up a MEGA-RARE seabird any day. Just ask SANDY KOMITO for whom the HAWAIIAN PETREL, was a LIFE BIRD!
PINK-FOOTED SHEARWATERS, above and below, often fly right up the wake of our vessel, giving excellent views and photographic opportunities. Other shearwaters we often encounter include: SOOTY, FLESH-FOOTED, BULLER'S, and rarely, STREAKED, WEDGE-TAILED and GREAT. 
By now, we have probably glimpsed the strange OCEAN SUNFISH, (Mola mola), basking at the surface. 
A large "blob" of warm water settled along the California coast last fall. With it came some species of seabirds that we haven't observed for a few years, including this SCRIPPS'S MURRELET, below. It looks like 2015 will continue the warm water trend. 
Typically, when we stop to look at a RHINOCEROS AUKLET, the BLACK-FOOTED ALBATROSSES fly into the wake. They often sit on the water for close inspection, as below. 
 Off Point Pinos, during fall migration we find SABINE'S GULL, below, and ARCTIC TERNS, sometimes in large flocks. These birds are usually pursued by POMARINE, PARASITIC and LONG-TAILED JAEGERS, as well as SOUTH POLAR SKUAS. 
 Often we head to the northern canyons which lie off the coast of Davenport because this is where the STORM-PETREL FLOCKS were last found. These flocks can include the following species of storm-petrels: ASHY, BLACK, LEAST, WILSON'S, sometimes FORK-TAILED, and rarely, LEACH'S and WEDGE-RUMPED. 
 In addition to seabirds, marine mammals can be quite spectacular in Monterey Bay. A huge variety of whales, including HUMPBACK, BLUE, GRAY, MINKE, FIN (rarely); BAIRD'S BEAKED WHALES, ORCAS/KILLER WHALES (above and below) and dauphins: RISSO'S, PACIFIC WHITE-SIDED, NORTHERN RIGHT WHALE and BOTTLENOSE, as well as HARBOR and DALL'S PORPOISES. Many of these species are observed on our Monterey Bay trips. We often spot the whales for the whale watching boats!
KILLER WHALES, above two images, often approach our vessel very closely, especially when they have made a kill. This can be quite spectacular! 
 Over the past four decades nothing has changed more in Monterey Bay than the return of the HUMPBACK WHALES. For the past two years, no fewer than 100 HUMPBACK WHALES have been photographed, feeding on schooling fish in the bay! The Humpback above, is breaching just off the Pacific Grove coastline!
Returning to the harbor after a most enjoyable day, checking our checklists, and relaxing in the afternoon sunshine, we see the sailboats out doing the same thing. Oh, well, maybe not checking their checklists!
We present, below, the 2015 Shearwater Journeys' fall schedule of pelagic trips departing from Monterey. These trips can easily be combined with trips departing from HALF MOON BAY, SAUSALITO (to the FARALLON ISLANDS), or possibly BODEGA BAY, for a well rounded pelagic experience. It is always best to book more than one trip, from different ports, if possible. Debi Shearwater will be on every trip. By being out there on so many different trips that cover such a large area of the Central Coast, Debi can develop a good picture of how and where the seabirds are distributed — something that changes every year, and even within the season. The ALBACORE, September 12th trip which departs from Monterey is a specialty trip. Please note that on all of the trips, we shall not be out of the sight of land, unless it is fogged in. You can also view the complete schedule on on web site. Or, view it in calendar format, here. Generally, Monterey Bay trips head north, while Monterey Seavalley trips head south. However, we always go where we think we'll find the best diversity of seabirds!

DETAILS FOR MONTEREY BAY TRIPS:
DEPARTURE: 7 a.m. Fisherman's Wharf Monterey. Stop at Chris' Fishing Shop on the right hand side as you walk down the wharf. They will direct you to the boat and give you a parking voucher. (Albacore trip meet at 5:15 a.m.). 
RETURN: 3:00 p.m. Allow for delays.
PARKING: Parking can be confusing in this area, as there are two different wharves. Park in the big lot near Fisherman's Wharf. Follow the signs. Take a ticket from the machine upon entering the lot. Stop at Chris' Fishing Shop and let them know you are on the Shearwater Journeys' trip. They will give you a coupon which will significantly reduce the parking fee. Allow 10 minutes to park and walk to the shop, more time if you do not know where you are going, or need to stop to use the restroom. Try to check this area out the day prior to your trip. 
PRICE ADJUSTMENT: Should the pricing increase, an adjustment may be necessary at the dockside, from $5-15 per person, payable in cash only. Do not send payment ahead with your reservation. This will only occur if rates increase. (Rates on this schedule were posted in October 2014). 
FOOD & DRINKS: Please bring all food and drinks, including water in a small day pack. None is available on the boat. 
MOTELS: There are thousands of motels in the Monterey area. However, they can be fully booked, if an "event" is happening — which is often. Booking motel rooms ahead of arrival almost always results in lower rates, as opposed to walking in the front door without a booking. Motels in the sleepy town of Pacific Grove are especially nice with easy access to birding along Ocean View Blvd. for rocky shorebirds. A bit closer to the wharf (but still requiring a vehicle), any motel on Munras Avenue is fine. 
RESERVATIONS: $168/person. DISCOUNT of $40 to celebrate our 40th year, if booked by 1 JULY. No refunds on discounted trips. The Albacore trip is $199/person (discount not available for that trip). Please follow instructions on the web site for booking. 

JUMP ON BOARD! 
HELP US CELEBRATE OUR 40TH YEAR!
SHEARWATERS FOREVER,
