Microlocalzonoweirdness

April means a lot of things to a lot of people, but one thing it means around these parts is the departure of the Zonotrichia. Golden-crowned and White-crowned Sparrows make up such a large proportion of the passerine avifauna in northern California for so much of the year, it's always strange to realize one spring day that they are gone until September. Well, nuttalli White-crowned Sparrows don't migrate, but you know what I'm saying.

Both of these birds are common feeder attendants here at Rancho de Bastardos, so of course I am always checking them for a White-throated or a Harris's while I still can, or something even more unexpected...and the unexpected did finally arrive. Last week I was surprised to see the bird pictured above.

This is a newly-arrived migrant that has made a prolonged stopover here at the Rancho. It has been here over a week now, and is easily discernible with the naked eye from the living room. At first I thought it was just a slightly aberrant White-crowned Sparrow, but there is more weird to it than just the almost entirely missing postocular line.

Also surprising is the amount of contrasting white in the throat and malar area, and the thin black crown stripes.

The bill is pinkish, distinctly different from the other orangey-billed White-crowneds that populate the Rancho.

View of the back of the head.

It's a weird bird. I've never seen a great number of White-crowned Sparrows and have never seen one like this. It's the same size as a White-crowned, though does seem bulkier at times. It's definitely not molting, it's a very fresh, bright looking bird. I heard and saw it sing once, and it sounded pretty much like the other White-crowns here.

Right. Don't worry any longer, I will ask The Question you have all been waiting for...is it a hybrid? Could it be that great unicorn of the Zonotrichia, a White-throated X White-crowned Sparrow? An F2 even?

Well, this isn't a quiz bird. Your guess is as good as mine, or better....or potentially far worse, depending on who you are. Let's be honest. I don't have total and complete confidence in identifying it, this is essentially a new bird for me. It's worth mentioning that sometimes the bird gives off a very White-throated vibe, appearing very plump and having a long, flattened crown in profile. If it is "just" a White-crowned, it sure has a lot of mutant characters appearing all at once.

I am inclined to say that this is a hybrid. For reference, I checked eBird of course...there are a total of four White-throated X White-crowned Sparrows with photographs in eBird. One is obviously a Golden-crowned Sparrow and is hopefully being purged as I type this, but the others bear a significant resemblance to this bird. Notably, they all have the minimal (vestigial???) postocular line, though it is such a bold feature on both parent species.

What do you think? In any case, it's fun to have such a weird bird lurking around here at Rancho de Bastardos and have the chance to study it at length.

In case you are wondering, the Golden-crowned Sparrows are looking sharp now. No study required, only appreciation.

Las Gallinas - Zono Zone, Let The Kinglet In, The One You Least Suspect (LISP)

Sorry for the lack of output lately buddies. Unsurprisingly, it becomes harder to blog when you are hanging out with a baby all the time. I've gotten plenty of good birding in this winter/spring though, so I have no shortage of material to work with...shit, I even have flowers.  But before I could even blog it, the Quasi-Perpetual Weekend (QPW) has come grinding to a halt...it's back to work for me. I've been off since my daughter was born in January, so this is going to be weird.

One of the things I've been able to take advantage of during the QPW was my proximity to Marin. Among northern California birders, few counties hold the appeal that Marin does. While I've lived in a number of places in the bay over the last ten years, I've never managed to live in Marin, which is widely considered the best birding county. That said, my current home in Albany is just a quick 15 minute drive over the Richmond Bridge to the Promised Land. I've spent a great deal of time birding in Marin since last fall, which has paid no end of dividends in terms of rarities and quality outings.

The Las Gallinas Ponds is a default birding location on the Marin bayside...you can rack up over 60 species pretty easily for much of the year, it has rarity potential, and a lot of the birds are highly crushable. Indeed, if you enjoy running into photogs who can't identify the birds they are shooting (who doesn't?!), then spend some time here!

Marsh Wrens are extremely common here (not unusual), but there are so many of them that you are bound to get good looks at a couple (unusual).

Common Gallinules are a highly local species in the bay area, and there is no better place to see them than at Las Gallinas. They are totally fearless here, even more so than the coots. Close observations of gallinules will lead you to conclude they are more interesting than coots in almost every possible way, except their feet are not as cool. Coot feet are hard to top. I'm not sure why gallinule feet are so simple in comparison, considering their niches and behavior overlap so much.

Did someone say "common"? Oh good, now I have a reason to post a White-crowned Sparrow. We have them year-round here, but they still are very much a scourge of winter.

Your friend and mine, the Great Egret.

This photo begs a question...without googling, does anyone know what bird species has the longest neck? Either in proportion to its body, or actual length? This seems like important trivia to know.

Don't worry locals, I managed to slip in one rarity in this post. After a substantial time spent dipping on this bird, eventually I connected with the Harris's Sparrow at Las Gallinas. Though not a MEGUH by any means, this is a solid rarity in California, and since I didn't see any last year it made for a fine yankee bravo, as well as a Marin County bird. Unfortunately it disappeared after about 30 seconds, and I was left wallowing around in more common birds...

Golden-crowned Sparrows are abundant and often very confiding...too bad most of them don't look very impressive until April or so. But what they lack in aesthetic appeal, they make up for in humble plumpness.

Wow, did I just throw up pics of three Zonotrichia? Perhaps it is time to brush up on these horsemen of the apocalypse.

Unlike Zono sparrows, Cooper's Hawk is not a bird I encounter up close very often. Practically everything at Las Gallinas is begging for merciless crushing.

I am not above posting the occasional House Finch photo...and by occasional, I mean this is the third one BB&B has ever posted since 2008. It was time. Come on, I know you are programmed to not even look at it, but it's a pretty bird, admit it. It looks good with that lichen...this is something you and I have to accept. Hey, if you are ever going to find that vagrant rosefinch, you're going to have to look closely at some House Finches.

Now that we got that out of the way, we can let this Ruby-crowned Kinglet into the empty cavities of our hearts. Don't be afraid...just let it in.

This is, without doubt, the best Ruby-crowned Kinglet photo I have ever taken. This is not a boast (that would be embarrassing), just simple fact. I dig how yellow the tail looks on this individual, that's not something I notice in the field very often.

Lincoln's Sparrows often fit the descriptions of murderers that you hear about on local news stations...they are quiet, nice, keep to themselves. Wouldn't harm a fly...or so you would think. No one would ever suspect them of breaking the law at all, let alone capable of killing nine people.

This is definitely a species pulling stakes right now; I've probably seen my last of the spring already. I've mentioned here before how they never sing at wintering/stopover sites in California. Do they just fail horribly the first few times they sing each year? They are probably spot-on, but I like the idea of them having to sing out the rust.

A few minutes away from Las Gallinas is the Marin Civic Center. There's a big, weird artificial pond there which attracts some gulls and ducks and has pulled in a couple interesting birds in the past. I recently discovered that it has tame Common Mergansers, which is heck of novel to me.

I've never seen them so close before. That is probably an odd notion to some of you, but now you know you can become #7 without ever getting close to Common Mergansers. As you definitely can tell, they were looking for delicious bread handouts (that's why they evolved serrated bills, obvi), but they are pretty striking birds regardless of the lowly intentions of these individuals.

Ok, I think I used up all my blog stamina. I've got to save energy for the next post, as that will deal with something I've been needing to tell you about for a long time....a long time.

An Ancient Harlan's Hawk, Newt Problems, Shades of Merlin

As any California birder knows, Humboldt offers a lot more than just the (very) occasional Great Gray Owl. There is no shortage of good birding spots to scour during the winter, so of course I had to check some other shit out while I was up there. I birded Arcata Marsh, since it is conveniently located right in town and just about anything can show up there...the dependable Swamp Sparrows I was looking for were not very dependable on this day, but the much more range-restricted Golden-crowned Sparrows were there in predictable abundance.

Unlike most birding spots, the marsh continues to grow in size and simply gets better and better when it comes to shorebirds and waterfowl, possibly to the detriment of the local Short-eared Owl population. This Greater Yellowlegs was feeding right in the face of this Green-winged Teal, foraging on little inverts the teal was stirring up with its bill. When you have a height of only a few inches it must be strange to have a yellowlegs looming over you, but the teal did not seem to mind.

This was apparently a successful foraging technique, as the yellowlegs did grab something while I was watching.

Over on the V Street Loop, this Great Blue Heron had gotten a hold of a much more interesting prey item...a large newt.

The heron did not appear to have a good idea of how to go about eating the newt, repeatedly dipping it in water, bashing it against the grass and not giving attempting to swallow it at all while I was there. This is an awkward thing to prey on at best, extremely toxic and deadly at worst. Native Americans in the Pacific Northwest used newt juice as a poison...

On the far side of the loop a cooperative Merlin was posted up on...a post. This bird struck me as being fairly pale, with no mustachial stripe...in the field I thought it was a female, but looking at the photos now I don't feel so sure about that. Interesting bird, I'm not quite sure what to make of it as far as age/gender/subpecies.

Elsewhere in the bottoms, I came across another, especially confiding Merlin. This bird was noticeably darker with heavier markings on the breast and belly than the first Merlin of the morning, but I'm not enthusiast about pulling the trigger and calling it a "Pacific" Merlin (I would expect a darker face and even more streaking/barring on the breast and belly). The vast majority of Merlins I've seen over the years usually zip by, giving shitty looks...I'd like to have more time to watch these birds and get to know each subspecies more.

For all you robin-strokers out there, here is an American Robin. There are thousands in the Arcata Bottoms in the winter. It is known.

Much, much more interesting than the area robins was this Harlan's Hawk. This bird has been wintering along the Highway 101 corridor between Eureka and Arcata for over a decade (!), usually near the Jacoby Creek Cutoff. In the past, I had only seen it while on the freeway, getting a quick naked-eye glimpse of it perched on a billboard or something and thinking "Oh, that was probably the Harlan's", but I finally managed to get great looks at the bird on this trip.

The bird is extremely dark, lacking any "warm" tones whatsoever. Fitting for an Alaskan bird. The uppertail (not visible in any of my photos) appeared dark gray without a hint of red, with a prominent dark subterminal band.

Although I never saw it fly, this bird definitely provided the best looks I've had of any Harlan's. Hopefully it will make it back to Humboldt this fall once again.

It was a relatively quiet winter in Humboldt as far as rarities go, but with a Snowy Owl (that I gleefully did not chase) showing up shortly after I was up there, the winter Vague Runt season ended for local birders on an extremely high note. What will show up next winter? Steller's Eider? Gray Wagtail? Black-tailed Gull? Siberian Accentor? The possibilities boggle the mind.

Manuela The Mandarin, Stowed Sparrows, Winter Gulling

Damn...no more Mexico posts...I guess I could finish off posting about the Costa Rica trip, but that would be too, um, prudent. I think I'll get caught up on winter birding instead.

After Mexico, Don Francisco and I birded for a few days around the bay, racking up year birds left and right. Don Francisco found this Greater White-fronted Goose at Golden Gate Park, which is always a nice bird to see in San Francisco. If Don Francisco ever finds a bird rare enough, I'm just going to start calling him San Francisco, which will thoroughly confuse everyone.

Golden-crowned Sparrows are supremely crushable at Stow Lake, and this bird got smashed pretty badly. I think I might have hurt it.

Fox Sparrows are usually not as confiding as crowned sparrows and are more interesting to look at, so I could not help but steal the (apparently grainy) soul of this bird.

This is a Sooty Fox Sparrow, the common form in northern California. Will the large and confusing pile of subspecies that comprise Fox Sparrow ever get split? I'm going to go on record here with a "no".

I will even take junco pictures still. I am a man of all birds.

See...I will even photograph a non-countable exotic! How embarrassing! How low can you go? I'm really scraping the bottom of the birding barrel here. Anyways, this is the same Mandarin Duck that has been at Stow Lake for over a year now. She still occasionally gets identified as a Wood Duck...but hey, there are worse mistakes one can make. She is not as popular as "Manny The Mandarin" and does not have her own Facebook page, which upsets her, but the world of birding is better for it.

If a Great Egret wants to sit a few feet away for a quick crush sesh, then I will oblige it. They're still pretty impressive birds to be up close to.

After dropping off Don Francisco, I went back out to the Richmond herring run to see if I could hang out with the Slaty-backed Gull some more. As expected, there were many Mew (left) and Thayer's (right) Gulls gorging themselves on herring roe.

This first-cycle Thayer's was a good-looking bird, already acquiring a lot of pink in the bill.

I refound the young Glaucous X Glaucous-winged Gull that we had seen earlier in the week. Not a bad looking bird for a hybrid gull.

The best find of the day was this adult Glaucous-winged X Glaucous Gull...just look at all the white on the primary tips....frosty! I had never seen an adult of this hybrid before, so I had some mild stoke going with this bird. Come to think of it, I've still never seen an adult Glaucous Gull...its a sad state of affairs.

Compare the hybrid's primary pattern with the Glaucous-winged Gull's primaries conveniently poking out from the left side of the frame.

Glaucous-winged X Glaucous Gull with a typical Glaucous-winged Gull below. I assume adult GWGU X GLGU primarily winter north of California, which is definitely how GLGU arrange themselves.

It's not unusual to find banded Western Gulls in the bay area, as they have been banded on the Farallon Islands for many years.

This Western Gull, silver-winged, leucistic Western Gull was a cool bird to see, and possibly the best Western Gull I've ever laid eyes on.

It's not unusual to see thousands of Mew Gulls at herring runs. Patches of the bay can be open, uninhabited water one minute and a seething froth of Mew Gulls the next.

I did not get to do as much gulling last winter as planned, and my multiple-year streak of not seeing any Glaucous Gulls continues. I'll miss these vulgar displays of Larus, but not being confronted with numerous birds (often at once) that are better left unidentified. No point in stringing, is there?

I Still Fiend For Vague Runts, But I Can Actually Look At A Common Bird (And Enjoy It)

Hey buddies. Felonious Jive (The Great Ornithologist) and I have just not been good bloggers lately. We've hardly been birding, to be honest. Between work and raging super fucking hard various social obligations, life has been pretty eventful, but not in any avian sense. In fact, I've been birding so rarely of late that I can now actually look at a common bird and enjoy it. Like today I looked at avocets and was able to appreciate them, instead of wishing they were a different shorebird species that were more apt to have rarities associating with them. Of course I still fiend for Vague Runts, but in time, my urges will be sated, once again. Thank Christ that goddamned pipit is gone so I don't have to think about it anymore; the Brambling doesn't hurt nearly as much.

That said, let's start this post with a Vague Runt Tropical Kingbird. Tropical Kingbirds are not unusual in late fall up and down California, generally a low-level rarity along the coast, but we don't get tired of looking at them...especially when they are vomiting. Lake Merced, San Francisco, CA.

Did you think I was being cute or something? That UFO on the left side of the photo came out of the kingbird's mouth. Look how far away the kingbird was able to fling it! Talk about hurling.

This female Black-throated Blue Warbler spent some time at Mendoza Ranch on Point Reyes last month. I know this isn't really a crush, but bear with me...it was really dark under the canopy and my ISO was set at something like 50,000, so it's amazing that anything is visible at all.

Also amazing is how confiding members of this species can be. It always astounds me...for whatever reason, they just don't seem to give a fuck. A bird on the Dry Tortugas brushed me with it's wing. This bird was feeding at eye level, less than 3 feet from my face. If you want to suck someone into birding, arrange for them to have a meeting with a Black-throated Blue Warbler. They will be hopeless bird junkies after that.

I said I would give you common, so I'm going to give you common...here is a Common Raven having an aerial tangle with a Red-shouldered Hawk. Photographed at Lake Merced.

The same two birds. I would imagine that if you are any sort of bird of prey larger than a Sharp-shinned Hawk, you would hate ravens. They are relentless in their harassment of raptors, and apparently impossible to kill. Anyone ever see a bird of prey get a good whack at a raven?

Not common, but Tricolored Blackbirds are to be expected on outer Point Reyes. This male is showing off that long bill that can often be of great use in distinguishing them from Red-winged Blackbirds.

Here are a pair of female Tricoloreds, wallowing in shit. Don't feel bad for them, they love it!

Golden-crowned Sparrows are horrendously abundant this time of year, but they are still fun to encounter by eye and ear. Even though the bird is sitting on an "artificial perch", I'm kind of into how intensely brown this photo is. #Shadesofbrown is the new #Shadesofgray. Arrowhead Marsh, Oakland, CA.

Although I've met a number of Common Loons that seemed pretty fearless, I don't meet Red-throateds very often that lack their species' usual disdain for humanity. Photographed at Arrowhead Marsh.

Brown Pelicans are truly charismatic birds, being capable of both inspirational majesty and baffling clumsiness. I honestly think this is a species that nonbirders (with the exception of some fishermen) appreciate more than birders do, since they are huge, abundant, highly visible, and prefer to fly awesome routes in tasteful formations. Photographed at Arrowhead Marsh.

Raptors aside, I can't think of another bird in the bay area that is more fun to watch while they are feeding. Photographed at Arrowhead Marsh.
