Pelagics Are Coming (And So Is El Niño?)


Long-tailed Jaeger. Late summer and early fall boat trips generally encounter the highest number of this fan-favorite as they migrate south. Photographed off Bodega Bay, CA.

There are a few ways of looking at birding this time of year in the Lower 48. Those of us who live in shorebird-inhabited areas know that the first southbound migrants of the year are already starting to trickle in, and it will be a very short matter of time before the first Siberian pops up somewhere (and we do love Siberians). However, those bird addicts who don't live in shorebird-inhabited areas are languishing in a deep, mid-summer depression...chicks are fledging, but birdsong is dying down and nothing is really oscar mike yet. But then there are those who can go to the beach, look west at the horizon, and shamelessly drool about the birds that can be found offshore.

Right...there are more than plovers and sandpipers to look forward to, for July is also the beginning of pelagic season. And this year, something different is in the water.


A widely and wildly-celebrated rarity in most states, Sabine's Gulls are expected on California pelagic trips. Southbound migrants begin moving through in July and are consistently found through October. Photographed off Bodega Bay.


It's not unusual to find sizeable flocks of them. However usual this may be, it never gets old. Photographed off Bodega Bay.

What is new for 2014 you ask? There are many signs that El Niño is taking hold, and seabird behavior in multiple countries indicates it is well on its way. Now, if you are not from California (the U.S. state that is typically most directly impacted by this phenomenon), you may not know what this means at all. Basically (very basically), ocean temperatures in the eastern Pacific lie within a certain temperature range, regulated by consistent wind patterns that cause upwelling of cold water. In El Niño years, there is a marked decrease in the amount of wind, and so there is less upwelling, and the eastern Pacific heats up.

The average California nonbirder knows that the warmer ocean temperatures El Niño brings increased precipitation, which is fantastic for us land-dwelling creatures that have been enduring a multiple-year drought. So that is good news. However, warm ocean water is not as productive as cooler waters, and this can (and does) cause the collapse of marine food chains. This means entire seabird colonies can fail to breed, and adults may not be able to fine enough food for themselves. Basically, it's a disaster.


A Flesh-footed Shearwater (left) and a Northern Fulmar crest a swell. Out of all the tubenoses that grace California, fulmars seem to be the most prone to wrecking on shore when oceanic conditions do not suit them...hopefully we don't see any significant die-offs this year. Photographed off Bodega Bay.


2013 was a very good year for Flesh-footed Shearwater (same bird as above) off central and northern California. This popular target bird for out-of-state birders typically do not become regular on trips until early September.

Disaster aside, certain seabird species prefer certain water temperatures and are well-suited to them. El Niño brings the high possibility of bringing southern, warm water loving birds northward into U.S. waters, and some birders (myself included) are trembling with the anticipation of what may come. While NOAA has not officially proclaimed El Niño to have settled in, they are giving it a high probability. Only time will tell for sure.

Recent previous El Niño events occurred in 2009-2010, 2006-2007, 2002-2003, and 1997-1998, with the 1997-1998 event being the strongest El Niño ever recorded. This year, Craveri's Murrelets have already been recorded twice in California waters (this is exceptionally early in the year for them, and many years they are not recorded at all). A putative Nazca Booby was recently photographed a few miles off of the Los Angeles County coast. 2009-2010 saw large numbers of Cook's Petrel recorded off California, with impressive numbers being recorded offshore with some regularity. It's impossible to predict what pelagic rarities will be found this year, but there are many disgusting possibilities. I hope to see you on a boat this year; I will again be a leader for Shearwater Journeys, and it's always nice to have some familiar faces on board.


If you want to find Short-tailed Shearwaters right now, you may want to be on a boat somewhere off the coast of Alaska. However, by late fall they make their way down to California where they are a good possibility on late-season boats. Photographed off Bodega Bay.


Same bird as above. Short-taileds have a habit (luckily for birders) of enthusiastically following boats that are chumming for birds, which is how Brian Patteson picked this one out last year. Sooties are not shy about making close passes by the boat, but they are not usually enthusiastic about getting in the chumline.


Many birders see their first albatross (of any kind) off central/northern California, and it's usually a Black-footed. Most boats from Monterey north to Humboldt encounter this loveable goony in summer and fall. Photographed off Bodega Bay.


Albatross employ all sorts of bizarre molt strategies. It's pretty easy to see what's new and what's old on this heavily-worn bird. Photographed off Bodega Bay.



You never know when a Laysan Albatross is going to show up! I suspect this is a juvenile bird, fledged only a few months previous. Note how there is no gray in the face, just a black eyepatch. Photographed off Bodega Bay.


Here is an adult, or at least a bird that is not a juvenile (Laysans generally do not begin breeding until they are 8 years old). There is a lot more gray in the face, which lends it a softer and far sexier look than the albajuveniles. As far as I know, there is no way in the field to tell apart a Laysan that is 2 years old and a Laysan that is 20. Photographed off Bodega Bay.




I guess I should show you a better look at an albaface. See? It is a lovely face. Older birds also have that 1/4 of a white eye-ring. #economyofstyle Photographed at Midway Atoll.


Brown Boobies always have multiple tails and wings, which give them a distinct "turboprop" look in flight. Photographed off Bodega Bay.


Well, maybe not always.


We had pleasant numbers of Scripps's Murrelets off of Half Moon Bay last year, where this pair was photographed. They are annual in small numbers in this part of the state, where they drift north after breeding is wrapped up off the coast of SoCal and Mexico. This is definitely a species more prone to occurring in warmer water.


I highly recommend studying Craveri's vs. Scripps's Murrelets before you get on a California boat this fall, or you may find yourself too slow on the draw. This is another Scripps's, photographed off Half Moon Bay.


Unlike the other pelagics pictured today, Marbled Murrelets stay quite close to shore (not to mention nesting in trees). While El Niño may help bring birders good birds from afar, many local breeders like this one don't stand to gain much if their food source goes north in search of cooler waters. By the way, if you are hoping to snag Marbled Murrelet on a pelagic, Half Moon Bay is consistently the best place to do it. Photographed in Half Moon Bay.




Yes! There are whales. Last year there was no shortage of Humpbacks (above) and Blues offshore. Photographed off Bodega Bay.




Could this be the year I pick up Red-tailed Tropicbird in my home state? I highly doubt it, but I really hope so...you just never know what is lurking offshore until you get there. Photographed at Midway Atoll.

How To Bird The Bay Area (Winter Edition): Part 1




WINTER IS COMING...and yet the onslaught of visiting birders never ends. I frequently get asked by out of state birders where to go around these parts, so instead of writing the same thing over and over again, I'm just going to lay it out all right here. I'm keeping out of state/country birders in mind here, so you locals please excuse all the titmouse-stroking that is about to occur.

Before we get started, there are some precious resources out there...make use of the new eBird Hotspot Explorer, the fantastic San Mateo County Birding Guide, this site and this site for Sonoma County...there are several more out there as well if you are willing to get a little dirty and do some cyberdigging. Being on top of all the listservs (and there are many) and eBird RBAs will keep you current on all the relevant rarities...but you already knew that, of course.




Short-tailed Shearwaters begin arriving off our waters in October, but are still far outnumbered by Sooty Shearwaters. Though this bird was photographed off of Bodega Bay, Bodega Head can be a very productive seawatching site.

Let's start with ocean birds. If you come in November, you might still be able to hop on a late-season Shearwater Journeys trip for pelagics, which could be very fruitful. A second option would be doing a whale watching trip that runs out to the Farallon Islands...this has been especially popular with birders in the past year because you can see the Pacific Ocean's only Northern Gannet that lives out there (yes, its still there). This won't be quite as productive as a real pelagic trip, but its far better than being stuck on land.

Northern Fulmar is the most abundant tubenose in winter months, and can sometimes be seen from shore. Photographed off Half Moon Bay.

If you are stuck on land and care to try your luck at seawatching, you can try places like the Pigeon Point Lighthouse (San Mateo County), Bodega Head, and various spots in San Francisco. You probably aren't going to be able to pluck out an albatross from the ether, but birds like Red Phalaropes, Ancient Murrelets and Northern Fulmars are possible. Of course, a scope is necessary. Red-throated, Pacific and Common Loons are common and can occur in many places along the coast.



A Black Oystercatcher at Miller-Knox Regional Shoreline, in Richmond. Oystercatchers are common along rocky shores and breakwaters up and down the coast, as well as various sites in the East Bay. They may blend in with wet rocks, but their piercing (borderline annoying) calls are hard to ignore.

For rockpipers, you have a lot of options...don't expect to be slinging glass at Rock Sandpiper (they are further north), but Black Oystercatcher, Surfbird and Black Turnstone are all common in the area, even in the east bay. Wandering Tattler is more common in fall, but is a winter possibility as well. Good places to see rockpipers include the Sutro Baths (and offshore rocks), Pillar Point Harbor, and the jetties at the mouth of Bodega Bay.



Long-billed Dowitchers (above) and Short-billed Dowitchers alike often roost in large flocks at the Radio Road Ponds in Redwood Shores. Photographers especially will be interested in visiting this place, where you are free to crush at will.

While we're at it, why don't we cover other shorebirds? San Francisco Bay supports huge numbers of shorebirds, both in migration and during winter. There are a multitude of places to get good looks at shorebirds...Radio Road, Foster City Shell Bar (Redwood Shores), Corte Madera Marsh (Larkspur), Bolinas Lagoon and Bodega Bay, Schoellenberger Park (Petaluma) to name a few. Of course, if you are planning on tracking down shorebirds anywhere around here, it's good to know what the tide is doing. Schoellenberger is the best place in winter for Pacific Golden-Plover, and there is often a Ruff around someplace in the late fall and winter months. Mountain Plovers winter inland, in Yolo and Solano Counties.



Cinnamon Teals are common and widespread in the bay area. The Radio Road ponds, where this bird was photographed, is a good place to see all three teal species, Eurasian Wigeon, Black Skimmers and Red Knots.

The bay area has a lot of good waterfowl to offer as well. Eurasian Wigeon, Harlequin Duck, Barrow's Goldeneye and Tufted Duck are all present in winter months. Lake Merritt in Oakland has had at least one Tufted Duck every winter for many years in a row now, and is very reliable for Barrow's Goldeneye in small numbers...also expect close-up views of five species of grebes, Canvasback, Common Goldeneye, both scaup, and some of the tamest night-herons you will ever meet.

Eurasian Wigeon can readily be found at Radio Road and Bolinas Lagoon, among other places, and may be present in any large concentration of American Wigeon. Black Scoters are regular off of the Great Highway (San Francisco) and near Mussel Rock, in Daly City; the latter site can have Harlequin Duck as well. If you are in the Point Reyes area, the waters around the Fish Docks on the outer point can yield Harlequin Duck, Long-tailed Duck, and three species of scoters. This area is very reliable for Red-necked Grebe as well.



Thayer's Gulls are fairly common in the bay area, but pose a difficult ID challenge nonetheless. A small female Herring Gull bellows in the background. Miller-Knox Regional Shoreline, Richmond, CA.

The bay area has been blessed with great gulling. Good gulling can often be found at Golden Gate Park (San Francisco), the Yolo County Landfill, Pilarcitos Creek (Half Moon Bay) and various creek mouths along the San Mateo coast. It's really not hard to find a good gull flock around here. A few Glaucous Gulls are found every winter, and it's definitely worth being on the lookout for Lesser Black-backed, Kumlien's Iceland Gull and Slaty-backed Gull, the latter particularly at Venice Beach (specifically, the Pilarcitos Creek Mouth) and nearby gull flocks in Half Moon Bay.



A pleasing first cycle Glaucous Gull photographed in San Francisco's Golden Gate Park. The small "lakes" in Golden Gate Park often attract a nice variety of gulls, including a number of Thayer's and the occasional Glaucous. Be sure to check Lloyd Lake for friendly Hooded Mergansers.

Of course, one of the highlights of bay area birding are the winter herring runs that occur December to March. At this time of year, herring come into San Francisco Bay en masse to spawn in shallow water, and when they do there can be tens of thousands of gulls feeding on both the adults and roe. Usually the listservs light up about the huge feeding congregations, so they can tell you where to go look at filthy gulls all day.

I'll wrap this post up with rails...aside from many coots, some Common Gallinules, and Virginia Rail and Sora, the bay area also hosts numbers of Clapper and Black Rails (and a handful of Yellows). I should stress your chances of actually seeing a Black Rail are very, very low (I've neither seen nor heard them) but it is not out of the question for the dedicated and/or lucky. A quick check of eBird will show they are found in a number of spots in the bay area (Palo Alto Baylands, Martinez Regional Shoreline, etc.); I recommend doing some research and going out at an extreme high tide where they are prone to be flushed from a marsh or pursued by predators (egrets, herons, gulls). And, of course, don't be a dick and blast rail calls into the marsh, they are a state listed and very sensitive species.

Unlike their smaller/excruciatingly timid cousins, Clapper Rails are not so secretive...their extremely loud calls and "duets" often give them away. The Palo Alto Baylands and Arrowhead Marsh (Oakland) are good places for these birds.

I think that covers a lot of good spots, although I know I left some out, (i.e. the huge network of salt ponds in Santa Clara County). Stay tuned for where to track down your most sought-after raptors and passerines.

Wait. I Thought We Weren't Supposed To Go On Pelagic Trips.


Rhinoceros Auklet. Not a Whiskered Auklet, despite the whiskers. But that's ok, because I have seen hundreds of Whiskered Auklets. No big deal.

Last month I had the opportunity to go on another pelagic with Debi Shearwater, out of Half Moon Bay, California. A big storm was coming in out of the north so we did not get as far offshore as planned, but we still managed to find a lot of the pelagic birds that one could reasonably hope for this time of year.

I'll post some more shots later. Today I'm going out to Point Reyes again to stare at a Dickcissel, amongst other things. Picture me birding.


Bonaparte's Gulls are stylish.


Red Phalaropes were seen on and off throughout the trip. They are too well-camouflaged for the brain of my autofocus, and this is one of the very few usable shots I ended up with.


A Sooty Shearwater impersonates a Black-footed Albatross, in order to mock all the birders on the boat hoping to see a Black-footed Albatross that day (we saw none).


Not tack-sharp, but otherwise I'm pretty happy with this Short-tailed Shearwater shot. They're not easy birds to accurately identify, let alone photograph.


Another Sooty Shearwater for comparison.


We saw a few Marbled Murrelets, including this rather "confiding" bird.


Northern Fulmars were often just a few feet off the stern of the boat. All the better to study their grunginess. For any nonbirders reading this, that strange apparatus on its beak is part of the bird's salt filtration system...they can drink salt water all day, no problem.


Pacific Loon. Economy of style.


The rarely seen cruise-missile flight mode of the Pelagic Cormorant. The pelican exploded a second after this photograph was taken.

Half Moon Bay Pelagic Part 1 (Life's Too Short To Have A Job)



Buller's Shearwater. 

Last month I went on a Shearwater Journeys trip out of Half Moon Bay....although not particularly birdy, we did have calm seas and a great diversity of species. Since I am a poor seasonal biologist (financially, not spiritually), I don't go on many pelagics...so I was pretty happy to be out there. Unfortunately, I was unable to witness anyone vomiting. Maybe next time.

If you have the misfortune of never going on a pelagic trip off California, consider yourself a sorry son of a bitch. On the bright side, you have so much facemelting tube-nosed goodness to look forward to. Here is the first part of a suite of pictures from last month.

Lastly, thanks to everyone for checking out BB&B...last month we had more blog traffic than ever! The Great Ornithologist Felonious Jive tries to take all the credit for this, and he may be right....I hate him.



Elegant Terns.



Norther Fulmar, the world's grossest seabird.


Short-tailed Shearwater. Yet another good bird with a bad name. Thanks a lot, forefathers of birding.



If you do not know this is a Brown Pelican, you are a bad person.


California Sea Lions. I wonder if there is a technical term for what they are doing here. I assure you they are not frolicking. Boiling maybe?


Common Murres. Any guesses on what that gull is?


Cassin's Auklets are terrible fliers, but strong runners.


I'll leave you with this terrible Flesh-footed Shearwater photograph. It's only the second one I've seen. Obviously, I need to be able to afford more pelagic trips.
