Scouting For The 5MC


The Five Mile Challenge (5MC) is coming up fast! It is scheduled for this Saturday, and if the weather allows it, I will be squaring off with two other vicious (have you met Miss Brown???), unapologetic nerds in Portland and Austin. As This Machine Nate is prone to saying, anything can happen. While I do have a major advantage of having San Francisco Bay in my circle, there are shortcomings as well...there is no real, killer hotspot in my circle, and there is a definite lack of fresh water. San Pablo Reservoir is in my circle, but since I don't have an EBMUD permit I do not think I will be able to bird it. I'm also worried I won't be very strong with passerines...well you can bet I will be strong as fuck identifying them, but there just isn't much diversity in my circle, and I think I may have to struggle with getting a lot of the birds that Flycatcher Jen could easily get (i.e. Red-breasted Sapsucker, Varied Thrush). And bla bla bla bla shit, I hope it doesn't rain the whole weekend.

As I mentioned before, my traditional patch is actually over five miles away, so once it was decided that the 5MC was on I had to do some scouting and scouring of some previously overlooked sites. If I was going to win, I would have to bird some places I don't often bird. Scouting has indeed panned out, and now I know a spot that could be critical for me is the area around the Richmond Marina.


I have spent minimal time birding here in the past and didn't have high hopes, but I was happy to see a male Black Scoter, which are very rare in San Francisco Bay. This is a bird I haven't seen in a long time...a long time. And I'm not talking about the species, I'm talking about this particular individual...I last saw it in 2013! This bird has been wintering here for a great many years, so it was nice to be the official refinder of the bird for the winter of 2016-2017. Most birders who have seen a Black Scoter in Contra Costa County have seen this one individual. And this individual, for whatever reason, let me crush the shit out of it.


Black Scoters are very uncommon in most of California, and practically never appear in places where you can get very close to them. Honestly, I had better looks at the Del Norte Common Scoter than I have had of Black Scoter anywhere. This bird was remarkably confiding, hanging out and flirting with Greater Scaup hens just a stone's throw from the shoreline. Even more incredibly, the bird was calling regularly, something I've never heard before...a mournful, descending whistle, kind of a like a more poignant Dusky-capped Flycatcher. I recently went back to the marina and actually found the bird by call...birding is weird.


So while not a major rarity, I was chuffed to get such good looks (yes, they were soul-satisfying) at this bird so close to home.


Of course, you can't see Black Scoter in California without having to sort through Surf Scoters, which almost anyone can muster some enthusiasm over.


Say's Phoebe was a bit of a surprise foraging in a small grassy area on the bayside, and aren't particularly common in my Five Mile Radius (5MR). Hopefully it will still be around for the 5MC.


An adult Horned Grebe uses its terminator eyes to great effect, slaughtering very small fish with cold efficiency.


An immature Horned Grebe uses its dusky eyes to a not-so-great effect, but will hopefully catch enough to eventually be slaughtering very small fish cold efficiency.


East coast birders are likely not so impressed with our faithful, scaup-loving Black Scoter. To compensate, here is a shiny Pelagic Cormorant to get your dirty gripoff juices flowing. Unlike our other saltwater-loving cormorant (that's Brandt's Cormorant for you n00bs), they are fairly common in San Francisco Bay and aren't relegated to the area near the Golden Gate.


On another trip to the Richmond Marina and surrounding bayside, it was low tide and the whole area was just being torn asunder by Black Oystercatchers. American Crows were also mucking about in the intertidal, procuring mussels, which the oystercatchers undoubtedly frowned upon...omnivore poseurs. Occasionally I'll see an individual like this one with pale fringes on its flanks.


To all the aspiring gull lords out there, sorry I haven't been posting many gulls lately, I don't know what to tell you. Do you know how many gulls I saw in Puerto Rico? Two. Do you know how many years it has been since I've seen a Glaucous Gull? Five. FIVE! Did you really need to know that? Possibly. Anyways, here's a Thayer's Gull and a California Gull. Thayer's will be a very good pickup during 5MC, hopefully it will not be a bird that gets left behind.


Out in the great, untamed wilderness that lies beyond the 5MR, other birds can be found. Our resident, introduced moffitti/maxima Canada Goose flocks often lure in other species, usually diminutive Cackling Geese. Martin Luther King Jr. Regional Shoreline, Oakland, CA.


Separating the two species here is usually a no-brainer, though other parts of the country do not have it as easy as we do (there are smaller Canada Geese and larger Cackling Geese subspecies further east). I would be stoked to get any goose species besides Canada during the 5MC, but we will just have to wait and see.

Nate, Jen....5MC is going to break you. After this, there will be nothing left of you beyond cracked shells, empty husks of what once were people. Everyone you love will shun you, beginning with your local birds this Saturday. And if I lose because it is pouring rain this weekend (which is the current forecast), I hope you except my butthurt gracefully.

Diver Cavalcade


The bay area is blessed (cursed??!?!!!?!?!) with an enormous diving duck population in the winter months...some of the state's biggest concentrations of divers are here, if the not the biggest. Mount Tamalpais watches over them, no doubt a knowing and powerful duck god. Miller-Knox Regional Shoreline, Richmond, CA.


Surf Scoters and Greater Scaup. Thousands of ducks convened at Miller-Knox last month to feed on the herring roe that had also brought in enormous numbers of gulls.


Herring runs are fun for ducks and gulls alike. Here they mingle in harmony...the mind reels.


Among the throngs of Surf Scoters was this lone male Black Scoter. Their preference of wintering sites in the state are generally not conducive to photography, so it was nice to finally get some photos of the yellow-knobbed enigma.


Black Scoters are rare, or at most locally uncommon in coastal California...they are probably not overly enigmatic either, although they have been less studied than other sea ducks. Population estimates and trends are imprecise at best.


Black Scoters of western North America breed entirely in tundra lakes of Alaska; the closest population of breeding eastern birds is in Hudson Bay. I wonder how genetically divergent these birds might be.


It was truly a vulgar display of fowl. The seas seethed and frothed with egg-laden ducks.


A high-density scaup flock scrambles for handouts. Nothing will churn the placid waters of the lake like a bunch of carb-loading ducks. Lake Merritt, Oakland, CA.



Aside from the coots and Canvasbacks, these are almost all Greater Scaup, with one obvious Lesser mixed in. Can you find it? If you can't, the Global Birder Ranking System will note your failure.


Is there a better place than Lake Merritt for Canvasback watching? I have yet to find it.


Red-breasted Mergansers around here are mostly females and young males...older males mostly winter to the north of us. Not sure if this is a young bird or if it's still molting out of eclipse (this was photographed a few months ago).


This Common Goldeneye is going into classic stealth mode, where they swim with their neck extended and head held just above the water. Doesn't seem particularly stealthy to me but they think it works.


Locals will recognize this female Redhead that has been wintering on Lake Merritt for the past several years. The white flecking on her head (a result of leucism, not old age) makes her easy to identify as the same returning bird.
