DADS TAKE THEIR CHICKS TO SEA: JULY 20 HALF MOON BAY PELAGIC TRIP REPORT

This is a trip report for Shearwater Journeys's July 20, 2014 pelagic trip departing from Half Moon Bay. Highlights and surprises included: BLACK-VENTED and FLESH-FOOTED SHEARWATERS; LEACH'S STORM-PETREL; SABINE'S GULL and CRAVERI'S MURRELETS. Offshore conditions were excellent with flat-calm seas for nearly the entire 11+ hour ocean trip where we headed at least 22 miles offshore. Our trip was rounded out with some of the more expected early fall seabirds, and of course, HUMPBACK WHALES. We encountered a lot of OCEAN SUNFISH, and for the first time in almost a decade, we saw many of the delightful BY-THE-WIND-SAILORS. We covered both San Mateo and San Francisco Counties.

This is the time of year when we see many pairs of "Dads & Chicks" — the father COMMON MURRE takes the newly fledged chick out to sea and cares for it for about 10 weeks. They stay together, the chick making a whistling call to the day who returns a guttural call back. 


Funny thing— I realized that we had some "Dads & Chick Birder Pairs" on board!

This young man ticked off 14 Life Birds! 
Birding begins right in the harbor! We could easily spend hours here!

Just outside of the harbor, we search for the Federally Endangered MARBLED MURRELET, above and below. Images by Beth Hamel, copyright.
At this time of year, they are still in their cryptic alternate, or breeding plumage. 
This tiny alcid, the size of one's hand, breeds deep in the redwood forests. 
 
Turning offshore, I was surprised and thrilled to encounter the beautiful BY-THE-WIND-SAILOR, below. We have not found this delightful little hydrozoan for nearly a decade.

BY-THE-WIND-SAILORS are small relatives of the Portuguese Man-of-War. They can carpet the sea at times, almost seeming as if it were possible to "walk on water" on top of them. 
It wasn't long before we encountered the first os seven pairs of CRAVERI'S MURRELETS, below. 
This fly-away view is more typical. However, we can see their very dark backs. These southern breeders have not been reliably reported in central California for many years, possibly a decade.

Usually, we encounter the first BLACK-FOOTED ALBATROSS once we get over the Continental Shelf. However, the first of 235 albatrosses appeared in only 30-50 fathoms on this day. 
 We headed to a fishing vessel that was pulling its' net, below. 
We counted more than 100 BLACK-FOOTED ALBATROSSES sitting on the water around this vessel. Look behind the vessel in this image, and you'll see two of these albatrosses. Raft of Black-footed Albatrosses above, copyright, Beth Hamel.

Dark morph Pink-footed Shearwaters exist and can easily be confused with Flesh-footed Shearwaters. 
Although Flesh-footed Shearwaters are more often seen from late September through October, they have been recorded every month of the year. 
 LEACH'S STORM-PETREL, below, image copyright Beth Hamel, was a real surprise. 
LEACH'S STORM-PETRELS are abundant far offshore (50-100 miles), but not nearshore (within 25 miles), which is where most one day pelagic trips go. This species is one of the most difficult to find storm-petrels on the West Coast on one day trips. 
Another one of the "Dad & Chick" pairs on this trip, this time with a "Mom," too!
The above family had studied well for this species!
Our Captain gunned the boat, chasing the Leach's Storm-Petrel so that everyone on board had great views, whether at the bow or stern of the vessel. This image by Jim Holmes was shot from the stern of the boat. 
Owing to our southerly route, we did not pass the weather buoy until we were on our way home.
Two CALIFORNIA SEA LIONS are seeking to win the "Darwin Award," having entrapped themselves inside of the buoy bars, seemingly with no way out! We'll check on them on our next trip, July 26!
 
We encountered loads of OCEAN SUNFISH in all sizes from the dinner plate size to large 4-5 footers. 
Many of the sunfish were "breaching," popping out of the water. However, we did see one albacore jump, too!

This "Dad & Chick," below, hailed form England. 
 
Back in the day — 1976 when I first began pelagic trips, leaders often identified this pair, below, as a "Common Murre and a Murrelet"! In those days, we didn't know that it was the father who took the baby murre out to sea! The chicks are noticeably smaller with smaller bills. We've learned a lot since those first years of pelagic birding, but we're still learning today. This is truly, one of the "last frontiers" of birding!

Another "Dad with his chick" below.  Teddy made his first pelagic trip with us three years ago when he was only six years old!
 We saw a few RHINOCEROS AUKLETS, including this adult, below.

 SANDY KOMITO & DEBI SHEARWATER, best of buds, below!
SANDY KOMITO of The Big Year fame, did his first West Coast pelagic trips with Shearwater Journeys in 1985! Talk about repeat clients — many return year after year with us! Sandy rarely ticks a pelagic Life Bird, or any new bird for North America. However, he did see a Lifer Hawaiian Petrel which Debi spotted on the August 2, 2013 Monterey Bay pelagic trip!

Drawing on many sources, I made a Plan A for the day's route the night prior. One of the many resources that I use is TERRAFIN's SST (Sea Surface Temperature) charts. In the chart above, the purple route represents, roughly, where we went on this day. We traveled further south than we usually do. Calm seas made that possible. The areas of white on the chart were areas that were covered with fog, preventing a satellite temperature reading. Terrafin is available to anyone, for a subscriber fee. Charts used with express permission from Terrafin.
For most of the day, the SST was between 59.8-61F. We went southwest to about 18 miles off Pescadero, and then up to the Pioneer Canyon, and home.

Our day was completed with views of HUMPBACK WHALES.
