Elevation Addiction: It's the Birding that Suffers

Butler's Birds has been just limping along for the last month or so, but let me tell you it's not correlative with a lack of walking. Given the oppressive heat and general dearth of stimulating variety in way of avifauna right now, my weekend birding time has been largely abrogated by weekend hiking time. Of course, ideally a lovely hike and lovely birds go hand-in-hand, but recent destinations and paces have had the unfortunate side-effect of limited birding. The most recent target was Humphrey's peak, about 20 miles north of Flagstaff in the San Francisco Peaks of the Kachina Wilderness. 


With a summit at 12,633 feet, Humphrey's is the tallest peak in Arizona. Humphrey's and the neighboring Agassiz Peak, 300 feet shorter, are the southernmost mountains in the contiguous U.S. above 12,000 feet, and estimates put them at 16,000 feet before their stratovolcano base blew up about 200,000 years ago. The hike from the Snowbowl trailhead totals a bit over 10 miles roundtrip and gains about of 3,000 feet in elevation. It makes for a pretty grueling and enjoyable trek passing through several ecozones, but even if one is willing to haul all the photography gear that is no guarantee of birds--at least, not half-way through August. 


As one might expect, a fair portion of the hike climbs through thick spruce, pine, and fir forest. Jays, Nuthatches, Chickadees, and Creepers maintain a constant chorus, and the occasional caterwauling of a Clark's Nutcracker belting by overhead adds excitement, but for the most part the birds are sooner heard than seen.


One of the most exciting ecological attractions on Humphrey's Peak is the bristlecone pines, some of nature's hardiest and longevous organisms. Up the volcanic slopes, where the spruce and fir evergreens dare not go, the scattered bristlecones still cling to the mountainside. 


In some areas, nearer 12,000 feet, there seem to be more skeletons than living trees. Mountains of this size are capricious masters, seemingly creating their own weather and always engaging in sweet and violent love with the forces of erosion. 


The bristlecones in this area are not nearly as old, massive, nor majestic as some of those farther north on the Colorado Plateau, but they'll have the last laugh a few thousands years from now when the little bits and pieces of us contemporaries are blowing in the air around them.


Although they're the most dominant life form at that altitude, to the extent any life form can be dominant at that altitude, the bristlecones are not alone. In addition to soaring Ravens, Hawks, and Eagles, American Pipits frequent these rocky slopes in summer time, where conspicuously young birds cut their teeth on the igneous slopes of Humphrey before descending to the warmer Sonoran plain in a few months' time.


There were even some leps up there doing...something. They're probably sipping sweet nectar out of the very rocks themselves. You've got to be hardcore to live up there. 


Even though it's about 190 miles away, the north rim of the Grand Canyon is also just barely visible in the great blue yonder from Humphrey's summit. It's not postcard pretty, but I will say that standing atop AZ's highest point and gazing into AZ's biggest crack is...a very superlative experience.

Citadel of the Gods, Afterthought of the Birds

This past weekend took Butler's Birds up to Utah for a friend's wedding. There was not really time nor was it the place to go chasing for Chukars, alas, but it was the time and place to view one of America's natural wonders: Zion National Park. The steep, jutting red rocks make for pretty impressive, scenic fews, but not so much for good birding--at least not the Angel's Landing area Apologies for the light dose of birds here. 


With the added effects of some heavy cloud cover and light rain, the whole place had a pretty groovy, Jurassic Park feel to it. The dinosaurs were pretty small though:


The Angel's Landing hike is a pretty steep trek up one of the Zion pinnacles. Wildlife was pretty minimal, but given the harsh conditions that was to be expected. Speaking of dinosaurs, the remains of some ancient trees made for interesting viewing. Did the trunk twist and warp from several hundred, even thousands of year of high winds? Did it just have scoliosis? 


Most of the canyon erosion in Zion is attributable to the Virgin River, a 162-mile tributary of the CO River that is untouched by dams (although the name comes from one of its American discoverers, Thomas Virgin, infamous for his poor social skills when chatting up the ladies).


Supposedly 270 bird species have been recorded at Zion, (215 according to ebird), most of which are found, no doubt, in the riparian corridor. The steep rock faces leave little soil and hold little water. As such there is little vegetation and even less room and resources for birds to fine purchase. Even so, Zion National Park is essentially a series of gorges and canyons, and some birds are unscrupulous skanks for that kinda stuff.




As This Machine pointed out a little while ago, July is not really the best time to be birding in most of the U.S. Migrations and vagration are mostly non-factors, and breeding activity typically has died down. Furthermore, lots of the birds are no longer as dapper as they were earlier in the spring. This Steller's Jay, while still a tasty piece of eye candy, had some weird neck-molt going on, a trademark of Jays and Cardinals.


It won't be too long now until the shorebirds start their trans-hemispherical odysseys, and the pelagic birding boats are already throwing back port on their starboard. This summer's birding had a couple of fantastic personal highlights but was bittersweet in that it did not get the full time and commitment commensurate to my anticipation back in May. Even so, it's a big and beautiful country and I got to see a little bit more of it.
10/10 would recommend.

Birding Loveland Pass: A World on Top of the World

Sorry to disappoint you, but Butler's Birds is NOT dead and buried. Buried maybe, under piles of work and the charred hopes and dreams of a full summer vacation that just could never be...but not dead. It has been far too long since last I launched my own tawdry offerings into the blogosphere. Fortunately this summer has not been totally bereft of birding, nor was my time in Carolina the last means of a salvo. Without much further adieu, we blast off and up to 12,000 feet, to Loveland Pass, CO, where breathing comes hard and the trees do not go.



I had been yearning for some high alpine hiking during most of June and July. I was not able to take the full week off to camp in the White Mountains of AZ, so a weekend scurry to Denver and back was instead on the cards. From Phoenix to Loveland pass is an 11,000 foot elevation change. Considering I had been up late tossing back margaritas, plus, you know, Denver, I did not arrive in the best state (of being).
And yet, for whatever reason, the birding gods were pleased with me. Maybe it was karma for holding down the fort and plugging away at an otherwise empty school office all summer. Most likely it was a just a bit of luck. As soon as I looked down the slopes, to one of the little islands of spruce scrub still growing above the predominant tree line, there sat a Pine Grosbeak.
YEEAAHH. The whole point of this hike was to get up above the tree line, a height to which I had never been before in the Rockies, and literally the first bird was a lifer--a really good lifer--with a tree in its name.


The Grosbeak took off and flew too far to be chased. In fact, simply climbing back up the hill afterwards took some doing. Exploring the little patch that it vacated, I found several other species of birds all crammed into the tiny spruce tenement. Wilson's Warbler, Rufous Hummingbird, Robin, White-crowned and Lincoln's sparrow were all chattering and positioning in the half-dead little trees. It was very interesting to see that many birds crammed into such a small space--like maybe 20 cubic feet. Looking at the surrounding landscape it made sense. The slopes leading up to the Continental Divide were barren except for very low-growing weeds and wildflowers, and in many areas snow patches still clung to the mountainsides.


And yet even where the green became sparse, at the dying edges of the mountain where erosion was master, animal life thrived. Of course, in areas with no tree cover and bitter cold in the winter, most animals have to be supremely and specifically adapted to survive. The grumpy rock sitting on top of the other mild-mannered rocks is a Yellow-Bellied Marmot. Males of this fat uber ground squirrel species spend like 3/4 of the year hibernating and the rest being serviced by a harem of females. Occasionally they have to post as sentries near their burrows and bark at intruders, or at least look surly.


Apparently there's a lot of variation in this species, because there is only one marmot species in the Rockies and this means these ruddy buggers below are the same as the heather-looking fellow above. At that elevation and in that environment, Marmots are probably the largest and heaviest critters around. P.S. Yes I did say the appropriate Big Lebowski line every time I looked at one.


On the other end of the size and industriousness spectrum of the rodent scale is the humble Pika. They're about the size of a plum and twice as delicious--according to local Golden Eagles. They do not hibernate like Marmots, perhaps due to a lack of relative fatness, and so instead spend all of their spring and summer time stocking up their larders with seeds and grass and what not for the coming winter. Apparently they have to accrue a mass of food reserves equivalent to an economy-sized sedan in volume. They make Marmots look like lazy sacks of sacks. As you may note, they also have an extra butt-pouch of fur, which allows them to sit comfortably in cold places.



Pika are pretty damn cute, but before you get wooed by them too much keep in mind that they habitually ruminate on their own feces two or three go-arounds...so there is that. Don't get too kissy.



Forget-me-nots are the state flower of Alaska. They are to other wildflowers what the tiny, sweet Pika are to Marmots, except without the proclivity for feces pieces. I need to start carrying around a short lens.


Another aspect of this summertime trip to the Rockies was reacquainting with birds that I usually see only in fall or winter--though some Horned Larks over-summer too--and in much different habitats. HOLAs principally hang out in dry agg. fields and empty ponds basins around Maricopa. They also do not have as prominent of horns.


Sage Thrashers hang out in sage brush desert areas, in case you were wondering. I'll be honest, I was not expecting to see this bird up so high. I need to pay closer attention to range maps.


Of course, the main reason for this trek was not to reacquaint with old birds nor breathe the fresh mountain air. It was not the supreme satisfaction of standing on a peak and knowing one is literally the closest thing to the heavens as far as the eye can see (sorry other hikers who are not as tall). The main reason any unreasonable person goes to such altitudes and clambers about on the scree, getting embarrassingly out of breath in the process, is White-tailed Ptarmigan.


WTPT are perhaps the pinnacle example of seasonal camouflage in North America. They morph all white in winter, seemingly melting away into their snow banks. Then as the snow melts away so does their alabaster; they become as mottled as any of the granite stones in which they find purchase. When sitting still, they are very hard to discern. Even after they've been found...they are still really hard to discern.


Especially considering they make very little noise (compare to the totally nutso sounds of Willow Ptarmigan) and are reticent to flush, pulling these birds out of the rubble can take some doing, but it is not without sweet, sweet reward.


Once they're singled out and established, once you are locked in and have them in the ol' heat-vision goggles, they really do not care about you or what you are doing or why you are changing your pants--yet again. I gotta say, seeing these birds and spending time with them totally floored me. They were far calmer than I was.



The initial sighting was outstanding. Even more amazing was taking a step forward as the first Ptarmigan shuffled on its way and realizing I almost stepped on another. Luckily she gave me a courtesy ruffle to differentiate herself from rocks. 


I wish I could say that she is bellowing here, as I would love to know what WTPT sound like, but in reality she was pecking and gargling stones--also pretty cool, and tough.


I was not sure I would see WTPT on this hike. I was not sure that if I did see them I would get particularly good looks. I had never seen any upland game birds before, excluding Ring-necked Pheasant. So, indulge me here, because it turns out WTPT will let you get pretty crushy.


If you have not participated in a Ptarmigan photo shoot before, I highly recommend it. They don't have the braggadocio eye comb of Spruce Grouse, but even their feet still look good, good and impressive.


WTPTs are not the most diverse birds when it comes to shape. They can be oblong, and they can also be blobular. Daedalus himself would get lost trying to navigate the labyrinthine patterns of this bird's plumage. This bird's breast...it's like a thousand tiny moths or skippers all came home to roost.


It's amazing to look at a creature like this and study the vast intricacies of its appearance, how each feather seems to be both unique and uniform at the same time. Focussing on that micro level makes it all the more intriguing that they can seemingly disappear into the rocks, even as one is still looking at them. How can something be that unique and yet blend into a part of everything else? 



There were also White-crowned Sparrows adorning the little spruce clumps, but who cares about that? Ptarmigans win.
