Marin Birding: The Le Conte's Sparrow, A Suspect Sapsucker and Reversed Gender Roles



Most sparrows don't earn the title "crippling"....but most sparrows are not Le Conte's Sparrows. Abbott's Lagoon, Point Reyes, CA.

The rut is over.  The birding doom and gloom that plagued the Global Birder Ranking System's #7 U.S. birder late this fall has lifted, and the Vague Runts have been raining down upon me ever since I lurked back north from the Salton Sink.  Have you ever had a vagrant shower? Try it some time...it is invigorating.  It is cathartic.  You are not immune to despondency...you need birds, and rare birds will really jolt your system.

As 2014 drew to a close, a few things became apparent:

Despite my consistent denials, people think I am Nelson Briefer. The One True Nelson Briefer.

Since we are on the internet and you can't see me, I can neither confirm nor deny that I am Nelson Briefer.

Therefore, I am possibly Nelson Briefer.

In my mind, I really don't think I'm Nelson Briefer. But am I? Dark forces may be at work.

None of this is relevant today's post, of course, which features some fine recent birding in western Marin County.


Le Conte's Sparrows are well known as one of the most skulking passerines to be found north of Mexico, and in the past that's held true for me. That said, if I were to have written this bird up for the Bird Police (which I did not do), I would have used this phrase to characterize it's behavior: It didn't give a fuck.


It truly didn't. We were all surprised. This was by far the most confiding member of it's species I've seen, which is fantastic since it looms on the verge of facemelting and I've only seen a handful in the past. It's also blindingly rare here on the west coast. No wonder this very species was responsible for tearing the San Diego birding community asunder, as "Todd Ingress" knows so well.


Perhaps you would prefer a more panoramic view of the Le Conte's Sparrow. Here it is, surveying it's domain of lupine.


When winter storms come through and strong winds blow off the ocean, it is not unreasonable to expect to find Red Phalaropes in northern California's coastal wetlands. On this cold, rarity-infused morning, Red Phalaropes had come off the sea to take a mellow respite at Abbott's Lagoon.



Look at this face. How can one know this face? How can one truly come to grips with a pelagic sandpiper? I get the strong impression that this is the most didactic of all shorebirds. It is telling us something, of this there is no question....and I think that something is this: Reverse your gender roles. Wear hella red, have sex and get in fights for one month a year, then dress simply and live at the whim of the ocean for the other eleven months. And whatever you do, don't raise your own offspring.


If you ever thought Seagull Steve was some kind of pipit stroker...you would be right. Here is an American Pipit, balancing on a pole. This is the sort of bird that makes casual bird enthusiasts not want to dive into actual birding...fuck that noise. I love pipits.


After Abbott's Lagoon, we headed back to Bear Valley Road, where both Yellow-bellied and Red-naped Sapsuckers had been reported from the same tree. We saw this bird, which definitely had a red nape.


But wait...something is off. The red cap seems almost contiguous with the nape, which no California birder ever wants to see. But there's something else...something is missing...


What is wrong with its face????


That's right...the bird has no white eye line on either side of the face. Not even a hint. Whiskey Tango Foxtrot. It's not like the bird is a super obvious hybrid, it doesn't have red all over it's head, but where there should be white there is only a resolute and very definite blackness. I've never seen a bird like this, have you? In any case, due to the nape patterning and facial weirdness, I suspect this is a hybrid Red-naped X Red-breasted, possibly backcrossed with a Red-naped.

Sapsucker of Confusion (Red-napey)


For whatever reason (where I live, my birding habits), I just don't see the number of sapsuckers that I used to. I have seen very few Red-naped Sapsuckers in the last several years, which is why I come to you now.



As you probably know, Red-naped and Red-breasted Sapsuckers interbreed frequently, and southern California gets a fair number of these hybrids. Backcrossing of hybrids with full-blooded Red-naped and Red-breasted certainly happens, which can lead to strange-looking birds. Recently in Ventura County, I had 6 sapsuckers in one set of pepper trees...2 hybrids, 2 Red-breasted, a Yellow-bellied with a broken wing, and this bird.


At first I thought the bird was a Red-naped, since at first glance it looks pretty much how a Red-naped Sapsucker ought to look. But then I noticed a subtle touch of red on each of the bird's cheeks...I know Red-naped is prone to having some red in the black eyeline behind the eye, but I've never heard of red in the white moustachial stripe as a known trait for pure Red-naped...of course I rarely see this species anymore, so I'm hoping those with more sapsucker exposure can chime in. Is this something to expect for Red-naped?


This bird's left side did not have quite as much red breaking into the white moustachial. Also odd was the color of the bird's nape; it was noticeably duller than the color of the crown and throat, but I don't think this is particularly problematic for Red-naped.



In the field I was leaning towards calling this bird a mostly Red-naped individual with some recent Red-breasted genes, but now I am leaning more toward an aberrant Red-naped. If you have experience in this realm, please leave a comment below, I'm curious to see what people think of these red-tinted cheeks. Anyways, a very sharp-looking and confiding bird.



Here is a more straightforward bird, present at the same site. I thought it was a Red-naped until I got an unobstructed view of the nape; it had a continuous red stripe running all the way from the forecrown to the base of it's neck, like a male Red-bellied Woodpecker. Nice-looking hybrid. The other hybrid present looked much more similar to a Red-breasted. All photos are from Canada Larga Road in Ventura County, CA.
