Red Wolf

 

A Red Wolf (Canis rufus) ambles my way. I think this is just about the moment she realized someone/something was watching her.

The highlight of my recent trip through the Carolinas, Georgia, and the Atlantic Coast of Florida was a mammal. In spite of it being primarily a bird photography trip.

The Red Wolf is one of the rarest mammals, anywhere, with perhaps seventeen individuals in the wild. All of them occur in the Alligator River National Wildlife Refuge in North Carolina. I was fortunate to see one, and beyond fortunate to get the looks (and photographs) that I did.

The wolf casts a last glance my way before trotting into nearby woods and melting away. She sports a radio collar - about seven of the wild wolves have these.

I'll tell the story of the Red Wolf in more detail here, soon, as it will be the subject of my next Columbus Dispatch newspaper column. Suffice to say it was an unexpected and thrilling experience. Fortune also literally shined on me as the light was beautiful and golden, and the sun was setting behind me.

A bit about how I came into such proximity to the beast. I had just turned onto a seldom-used gravel lane, headed towards a spot that American Black Bears frequent. Shortly after turning, I saw an object nearly a half-mile down the road, stopped, and glassed it with 10x binoculars. It was obviously a canid, although I could not tell if it was an Eastern Coyote or wolf from that range. But it seemed to be working my way.

I pulled the Jeep off the road, grabbed the 800mm lens/rig, eased out of the vehicle onto my knees, gently pushed the door shut (never slam doors!) and crawled around the back of the Jeep. It would have to serve as my blind, there was no time or opportunity to explore other options.

Amazingly, the animal kept ambling my way, stopping occasionally to look around and test the air. A few times it made brief forays into the vegetation. Perhaps it was hunting rabbits, which often come to roadsides around dusk. Fortunately for me, I was downwind so it couldn't get any scents, and the sidelined Jeep did not seem to interest it. As it drew nearer, I realized what I was looking at, crossed my fingers, and hoped it kept coming.

VEHICLE NOTE: My Jeep has auto headlights - they might have been deployed by this time. Fortunately, I had remembered to turn them off. When working from the vehicle in sparsely peopled areas, I usually keep the headlights off as long as possible. Had they been on when I turned onto the wolf road, the lights might have spooked the animal.

I've been forced to use the Jeep as a blind before, and when doing so rest the big lens butted up against part of the bumper, keep my body behind the vehicle, and thus offer the subject only a view of the lens' working end (the lens body is clad in camo) and a small part of my head and arm. It seems to break up my bipedal profile enough to sometimes keep warier animals from skedaddling.

Nearly everyone into natural history that visits this place knows about the wolves, me included. I just didn't expect to see one. Anyway, the animal eventually got to within 75-80 feet or so and was an easy mark for my big lens. The second shot above was my last, by which point she certainly realized that something was amiss. Her last pose was a beauty, though.

I probably could have just turned around and headed for home after this experience :-)

Loggerhead Shrike

 

As always, click the photo to enlarge

A Loggerhead Shrike (Lanius ludovicianus) watches for victims from a wispy perch. These predatory songbirds are brutish hunters and are sometimes known as "butcher birds". I must admit, I watched this animal for some time hoping he might score a kill. It did chase a Song Sparrow into a palm, but the sparrow escaped. Shrikes often impale their victims on thorns, barbed wire, etc. As the shrike lacks large powerful talons, sharp objects serve to hold their meal in place while the bird rips it apart.

Florida Scrub Jay, and Florida

 


A Florida Scrub Jay (Amphelocoma coerulescens), one of a clan of five birds that I encountered this morning near Hobe Sound, Florida. This rare jay, which is endemic to Florida, is but one of numerous interesting sightings on this expedition.

I left last Sunday, spent time in North Carolina then worked south into Florida. Working my way back to wintry Ohio now. When I return, I'll share more.

Ruby-crowned Kinglet eats Poison Ivy berries

 

I visited this birdy swath of edge habitat back on December 26, 2021. The first time I stumbled into this place, which is a bit off the beaten track in Slate Run Metro Park, Pickaway County, Ohio, was about a week prior. I wrote a brief piece about that trip, HERE.

Habitat-wise, there is much going on here. Just outside the photo to the right is a large mixed-emergent marsh. Behind me is a fairly mature patch of woodland. Older White Pine (Pinus strobus) can be seen in the photo. Plenty of dead American Elm (Ulmus americana) and Green Ash (Fraxinus pennsylvanica) lured lots of woodpeckers. But the biggest bait of all is prolific growths of Poison Ivy (Toxicodendron radicans), and most of the vines were heavily laden with fruit.

Nonnative Amur Honeysuckle (Lonicera maackii) and Multiflora Rose (Rosa multiflora) was also present, and birds were taking fruit from these plants. Especially American Robins (Turdus migratorius). While I will photograph birds at such plants, it's really not my bag. I do it mostly to document the feathered agents of dispersal that assist such plants in their spread. Not blaming birds for this, of course - many species are opportunistic survivors and will eagerly eat whatever palatable fare we leave in their paths. But I'm far more interested in documenting relationships between birds and native flora.

My main goal here was catching birds in the act of eating berries of the native Poison Ivy. This is a long-running bucket list project for me, and I might have 15-20 species noshing on the much-maligned plant by now.

But I was in for a surprise on this frigid morning and bagged an unexpected species.

While I have a number of images of Yellow-rumped Warblers (Setophaga coronata) in and among Poison Ivy plants, I had yet to capture a nice sharp image of one with berry in bill. Now I have. At least I think it's nice.

The importance of Poison Ivy to Yellow-rumped Warblers overwintering at northerly latitudes cannot be understated. In fact, I think the plant may be the primary reason that the hardy warblers can ride out cold and snow.

This phenomenon is interesting to me from a long-term perspective. Poison Ivy is very common, now, but it almost certainly wasn't in the not so long ago past. It is an opportunistic successional species, and the large-scale disturbances created by people have unintentionally created tons of habitat for it. I would bet that prior to European settlement, Poison Ivy was much better "behaved" and probably nowhere near as prolific as it is today.

A Ruby-crowned Kinglet (Corthylio calendula) caught in the act of eating Poison Ivy!

ASIDE: Those of you that are interested in scientific names may notice that this kinglet is now placed in the genus Corthylio. It long resided in Regulus, along with the Golden-crowned Kinglet (R. satrapa). Recent studies of kinglet genetics show significant variation between Regulus kinglets and the Ruby-crowned Kinglet. That, along with morphological differences (not to mention behavior) led to the segregation of the genera.

While I was standing quietly watching and photographing fruit-plundering birds, I heard the emphatic jit-jit call notes of a Ruby-crowned Kinglet. This is not a common winter bird in central Ohio, and I wanted to see it. Kinglets are inquisitive and a few crude imitations of its calls brought it raging in through the brush. It was a male, as it made known by puffing its scarlet topknot feathers.

After a bit, the kinglet forgot about me and resumed foraging. I saw it make a few sallies after (presumably) flying insects - probably winter-hardy species like winter stoneflies. It was also grabbing unknown items from branches and bark, these probably insects as well. Suddenly the sprite shot over to a Poison Ivy vine and grabbed a berry! I had read where they will eat small amounts of vegetable matter in winter, but I had never seen this behavior. In the half-hour or so that I watched the kinglet, it made several trips to grab Poison Ivy berries, usually taking a few fruits each time. Like most everything that kinglets do, he was quite speedy and it was tough to get a clear shot of him in the act. This is the only acceptable image that I managed, but it certainly provides proof that Ruby-crowned Kinglets occasionally join the ranks of Poison Ivy-eating birds.

Nature: Wandering woolly-bears well known, but can they predict the winter weather?

NATURE: Wandering woolly-bears well known, but can they predict winter weather?

On Dec. 12 of last year, I headed to remote areas of Muskingum County. Bird photography was my primary goal. The sun shone brightly, but it was a seasonally apropos 43 degrees for a high.

Especially alluring was a gorgeous northern mockingbird occupying a dense thicket. He was as interested in me as I was in him and popped out to closely scrutinize me. Mockingbirds are far more inquisitive than most songbirds and pay close attention to their surroundings.

His behavior allowed for great photo ops. Suddenly, the mocker dropped to the nearby roadbed and seized a woolly-bear! This is the first time I can recall seeing a bird take one of these heavily bristled caterpillars. Unfortunately, the bird shot into the thicket’s innards with his prize, and I could not see how he dealt with the larvae and its coat of spiky hairs.

The mockingbird tipped me to watch the roads more closely. I ended up seeing dozens of woolly-bears, and many giant leopard moth caterpillars (Hypercompe scribonia), which look similar.

Woolly-bears are perhaps North America’s best-loved and most familiar caterpillar. They are often noted — and frequented smashed — as they wander across roads. They can be active in very cool temperatures, especially if the sun is out. I’ve seen them wandering in temperatures in the mid-30s.

A woolly-bear is the immature stage of the Isabella tiger moth (Pyrrharctia isabella). The moth is quite attractive: creamy-yellow and burnt-orange, and sparsely peppered with black dots. In spite of its good looks, hardly anyone other than a lepidopterist would recognize the moth. But everyone from elementary school kids to the mailman knows the fuzzy, banded caterpillars.

One reason that so many people know them is because woolly-bears are abundant. The second of two broods of caterpillars hatch from eggs in late summer or fall, and the mature larvae seek sheltered nooks with the coming of cold weather. Once ensconced in its winter sanctuary, the woolly-bear will ride out the winter months and form a cocoon come spring.

But if it gets warm enough, the larval bears rouse themselves and wander, even in mid-winter. They are provisioned with nature’s version of hand warmers, chemicals known as cryoprotectants. These solutions allow the caterpillar to endure temperatures so cold that it becomes a larval popsicle, yet not suffer tissue damage.

It has long been held that woolly-bears are weather predictors: they foretell the severity of the coming winter. Legend has it that the wider the light-brown center band of the caterpillar, the milder the coming winter. Blacker caterpillars are an omen of a long severe winter.

Charles Curran, curator at the American Museum of Natural History, studied the woolly-bear band width theory between 1948 and 1956. He, his wife, and several acquaintances would make annual fall foliage trips to the area of New York’s Bear Mountain State Park, where they also encountered scores of woolly-bears. Curran kept fastidious notes on woolly-bear coloration in an attempt to link them to weather patterns.

Curran and his allies jokingly formed the Original Society of the Friends of the Woolly-bear. His larval weather correlations were inconclusive, and caterpillar forecasting can probably be put in the same league as that of groundhog Punxsutawney Phil and his winter-ending shadow.

Further throwing a wrench into woolly-bear weather-predicting is the issue of misidentifications. Giant leopard moth caterpillars also overwinter, are commonly seen roaming about, and greatly resemble black (bad winter) woolly-bears.

Yet another caterpillar active into early winter is the yellow-bear, the larva of the Virginian tiger moth (Spilosoma virginica). It looks like a pale woolly-bear, and thus a predictor of a mild winter.
