Astonishing (but Natural) Disappearance

Early one morning last week, I came out of the house to get the morning newspaper and immediately smelled a skunk. Skunks are often roadkill victims or prey for Great Horned Owls in my neighborhood, so I didn't give the odor much thought. On my way to the curb, I saw the source of the odor, lying dead alongside the driveway and--just out of the corner of my eye--a Great Horned Owl swooping off into the woods next door.

Then, about a half hour later, on my way out the door en route to work, I noticed that the skunk (and odor) had disappeared. Had I dreamt or imagined the whole thing? (Key some X-Factor theme music...)

About three days later, I was working in a brushy part of the yard and came across the tableau pictured in the image above. The skunk carcass had reappeared, this time accompanied by a huge owl pellet full of skunk hair. Mystery solved.

Winter Getaway: Riviera Maya in January

Quintana Roo, Mexico

For over a decade, I have pleaded with my wife to devote some of our vacation time to the Riviera Maya, the 60-mile stretch of beaches south of Cancun. We almost went several times, but every time we tried to book an eco-friendly hotel, it seemed like it had gone out of business, or had retreated to a new location further and further south of the burgeoning development spreading from Cancun, so we never committed. My wife is a university administrator and only has certain windows of time when she can get away when the university is not in session, and the time between the holidays and the Martin Luther King holiday is one of those times. She always complains that she has time off that she can't take, and that she hates winter, but we never do anything about it. So, this year, I took the bull by the horns and marched her into a travel agency between Christmas and New Years, and we booked a 6-day, 5-night trip to the Riviera Maya. Because it was so late (we planned to go before January 18), we didn't have much time to do research on accommodations, so we relied on the travel agent (and some quick reviews of Mexico travel guides), and chose an all-inclusive resort just outside the city of Playa del Carmen, about 30 miles south of Cancun. We're not "all inclusive" type people, and this was our first exposure to such a resort (sort of a mega-cruise ship concept on land), but I don't regret the decision.

We had a great time.

It could have been warmer (upper 60s and low 70s; typically, it's about 80 this time of year), and it could have been sunnier (partly or mostly cloudy nearly every day, with one full day of rain), but compared to the deep freeze gripping the eastern half of the United States while we were there, it was paradise.

We took two excursions, one to Si'an Ka'an, a national park/UNESCO biosphere reserve at the far south end of Riviera Maya, just north of Belize, and a second to Chichen Itza, the excavated Mayan city in Yucatan state.

Before we left the United States, I frantically tried to find a birding guide to Mexico. There isn't a single good field guide. The guides that are available are (1) too large to carry into the field, (2) too poorly illustrated, or (3) limited only to the birds indigenous to Mexico, excluding those also present in North America and migrants from North America wintering in Mexico. So, I express-purchased from Amazon the Peterson guide to Mexican Birds, and carried along my copy of All the Birds of North America. It was mostly all for naught, anyway; we saw very few birds--except for the utterly ubiquitous Great-tailed Grackles (Quiscalus mexicanus), which were everywhere.

Si'an Ka'an (the Mayan name for the area which means roughly "where the sky was born" or "contemplate the heavens") is a mangrove swamp-upland dry forest-coastal strand complex. We took a boat from the fishing village in the preserve, Punto Allen, in search of common bottlenose dolphins (Tursiops truncatus), sea turtles (loggerhead [Caretta caretta] and hawksbill [Eretmychelys imbricta]), and a Magnificent Frigatebird (Fregata manificens) rookery, all of which we saw. We also got to snorkel in the reef off Punto Allen, and to loll in a 4-foot-deep natural sandy Caribbean "swimming hole."

A group of six Italian tourists who accompanied us on our tour of the Si'an Ka'an Biosphere Reserve. We're all waiting for a sea turtle (visible just under the surface) to come up for air--which it promptly did just after I made this image.

Visiting Chichen Itza was something I had always wanted to do, but never thought I'd actually accomplish. It's probably in that book of 1000 Places to See Before You Die. It's really a remarkable place and, even though we were there for three hours and it was not particularly crowded, I could have spent at least several more hours there. I felt like we just scratched the surface of what's available. One aspect of the visit was a little disconcerting: there are hundreds of native craft vendors everywhere--outside the gate, inside the gate, and lined up along every inch of the periphery of the site. All are hawking their wares, and all have about the same kinds of items, most (but not all) of which are junk.

Yours truly at the great pyramid at the Mayan city of Chichen Itza.

Our daylong tour to Chicken Itza concluded with a stop at a cenote (water-filled sinkhole) for a swim. The Yucatan peninsula is underlain by limestone, which dissolves readily and collapses into sinkholes connected with underground rivers.


The beach at our resort, the Iberostar Tucan. In the center background, at the edge of the water, a huge, dark fabric bag filled with sand is visible. These erosion control devices, which we nicknamed "beach whales," were deployed all along the beach to try to retain the sand.

The developers left a small area of native habitat on the grounds of the hotel, then introduced some of the region's animals. This is a Great Curassow (Crax rubra), which lives in the Yucatan. I'd never be able to get an image like this if I were out in the forest.

Resident free-ranging wildlife takes advantage of the hotel grounds, too--even the developed portions; capybaras (Hydrochoerus hydrochaeris) roamed the hotel lobby, and howler monkeys (Alouatta palliata mexicana)made homes in the trees outside out hotel room. The hotel complex includes numerous interconnected ponds and watercourses containing huge goldfish--and many "minnows." This Great Egret (Ardea alba) (and several Snowy Egrets [Egretta thula]) knew a good thing when they found it. Breakfast is served (to humans in the dining room in the rear, and to the waders in the front).

Rivernorth Chicago Dance Company: Superb, As Always

Rivernorth Chicago dancers Cassandra Porter, Christian Denice, and Hanna Brictson in Tuscan Rift

Rivernorth Chicago came to town this week and gave a performance that affirmed my contention that this company is among the (if not the) most consistently inventive, delightful, and technically skilled contemporary dance companies performing today. The entire evening of seven dances was wonderful (with maybe one exception--Ella--danced to an energetic scat medley by Ella Fitzgerald), but two stood out above the rest: the first dance, Evolution of a Dream (2009), and the fourth, Forbidden Boundaries (2009).

Evolution of a Dream was a wee bit too frenetic and spastic for my anal-retentive demeanor, but the music was great, the energy was intense, and dancers were spot on. My wife turned to me after the applause died down and asked, "How are they going to top that?"

Well, they topped it with Forbidden Boundaries, a high point in a many splendored evening. The dancers were clad in sheer white blouses over white Speedo-tight shorts and halter tops. The bodies were perfect--especially that of Christian Denise (pictured above), who is incredibly well built but yet almost impossibly flexible. The dancers' blouses billowed like clouds that instantly transformed into restraints as partners yanked the blouses over the heads and shoulders of the dancers or bound their arms with the stretched sleeves. The piece built to a dazzling climax as the dancers finally rejected their restraints and boundaries, casting them onto the floor

I've seen Rivernorth Chicago three times before and have never been disappointed. The standing ovation they received on Saturday evening was more than well deserved.

New Year's Eve (2009) Walk

After leaving work at noon on New Year's Eve, we went for a walk on the rail-to-trail at the county park downstream of my usual natural area. It had snowed an inch that morning, and it was cold, but not cold enough to freeze the soil, so I didn't want to walk the trails in my regular haunt because it's very soggy there. We came across these massive icicles in the railroad cut called "The Gorge."

Along another part of the trail, we came upon another icicle formation.



I liked the way the water almost appeared to have congealed as it flowed over the rock.

Finally, we came to Harper's Run. In addition to the image I made on New Year's Eve, I've re-posted an image I made in the autumn from the same vantage point.

Solstice Sunset with Snow


The wintertime view from my office window just before I go home on the shortest days of the year just doesn't get any better. Last night, just after 5:00 p.m., this was the view.

Just a few minutes earlier, with a bit more light, the sycamore outside my office looked like this, still cloaked in snow from the weekend storm.

Snowy Splendor

Saturday's snowfall on the Mid-Atlantic seaboard set records. In our metropolitan area, the "official" gauge recorded the second-largest snowfall on record (23.2 inches) and the largest December snowfall ever. In our immediate area, we got about 16 inches of the white stuff. The trails in the natural area were too deep to explore without snowshoes or cross-country skis (neither of which I own), so here are a few images taken from an accessible spot around my house as I was shoveling--and shoveling--yesterday.

Appalachian Trail Trek

The Pinnacle Overlook along the Appalachian Trail in Berks County, Pennsylvania

The Sunday after Thanksgiving this year (November 29, 2009) in the Mid-Atlantic was spectacular--temperatures in the low 60s with cloudless skies. The day just begged for a hike, and we were happy to oblige. We tackled one of our favorite circuits--a 7-mile loop along the Appalachian Trail near Reading, Pennsylvania, that includes the best viewpoint in Pennsylvania, the Pinnacle. This portion of the AT is located just south of Hawk Mountain and shares many of the same physical characteristics with its more famous neighbor to the north: expansive views, challenging rocks, and soaring raptors.

One of the rare, relatively stone-free sections of the Appalachian Trail atop Blue Mountain

This circuit involves three separate trail segments. First, there's a quick, steep climb ascending 600 feet over a distance of about a half-mile. Whew! Then there's a long, flat, but extremely rocky section along the ridgeline of Blue Mountain. Finally, a side-trail returns the hiker to the starting point along a steep, downhill trail on an old logging road running beside a beautiful mountain stream called Furnace Creek, so named because it provided water for the nearby Windsor Iron Furnace in 19th century.

A tight squeeze for backbackers
Many Appalachian Trail through hikers consider the Pennsylvania portion of the trail the most challenging of all because it is so rocky. The image below shows one of the most--but by no means the only--challenging section of this circuit hike.

An especially challenging portion of the Appalachian Trail. This jumble of rocks is the trail.

The crest of the Appalachian Ridges is cloaked with a Mixed Oak Forest. This forest used to be called the Oak-Chestnut Forest, but the accidental introduction of the chestnut blight fungus in the 1920s all but wiped-out the American chestnut. It's niche was filled by chestnut oak (Quercus montana). The ridges are windy and cold, and the soil is acidic, well-drained and nutrient poor. Most of the trees are chestnut oaks, but there's a smattering of red and black oaks, black cherries, and birches in the woods, too. Labor Day usually offers a plethora of blueberries.

Chestnut oak (Quercus montana) replaced American chestnuts (Castanea dentata) in the Mixed Oak forests after the onslaught of the chestnut blight in the 1920s. Note the thick bark and the faded white AT blaze.

The Pinnacle Overlook--best view from the AT in PA
Most people hike this circuit to enjoy The Pinnacle Overlook, widely acknowledged to be the best view from the AT in Pennsylvania. At the peak of fall color, it can be hard to find a place to sit to have lunch here. This is the only place I have ever seen a rattlesnake in Pennsylvania; it was curled up under a ledge. There are lots of slump caves and narrow crevices to explore below the cliff face, too.

After three hours of hiking uphill and or crossing treacherous rocks, the third portion of the hike on the old logging road is a real treat.

Eastern hemlocks and rhododendrons line Furnace Creek

Furnace Creek is beautiful along its entire length. Here, I discovered a small falls about two feet high. Just below this point, Furnace Creek is impounded behind a dam to provide drinking water for the borough of Hamburg, Pennsylvania.

Because of the depauperate soil and relatively harsh conditions in the Appalachian ridges, wildlife is not common--especially in November. We only saw one Pileated Woodpecker (Dryocopus pileatus), one Black-capped Chickadee (Poecila atricapillus), and one White-breasted Nuthatch (Sitta carolinensis) in addition to the Black Vultures. Oh, and a small Eastern Garter Snake (Thamnophis sirtalis) that startled us by crawling across the trail--in November!
