Winter Birds of Beidler Forest

The cold snap has finally ended! After eleven nights of below-freezing weather and daytime temperatures in the 30F-40Fs, today's high is well into the 60Fs! The warmer weather already has us talking about the return of spring migrants. Seems like it is too early, but it is only six weeks before the Yellow-throated Warblers begin singing, followed by the Northern Parula Warblers and by the end of March we will be spotting Prothonotary Warblers!

Here are a few of the winter residents we spotted from the boardwalk yesterday:

Good Day to Take it Easy

The temperature warmed into the 40Fs at the Audubon Center at Francis Beidler Forest with a promise of 60Fs by Thursday! However, the cool weather kept the number of visitors to seven and kept most of the wildlife out of sight or resting.

Not a single reptile, not even a lizard, was spotted around the boardwalk and only a few birds made their presence known. Two that remained quiet, but were spotted anyway, were the Black Vulture (Coragyps atratus) perched in the sunlight high atop a Bald Cypress (Taxodium distichum) snag and a Barred Owl (Strix varia) in an oak that the owl pair has adopted as their "digesting tree." Vultures often depend on warm rising air (thermals) to lift them high above the ground and limit the energy required to stay aloft. Cold days like today offer little in the way of thermals.

Owls do not digest all the parts of the prey that they eat and regurgitate those parts in a compact pellet. Barred Owls tend to select a feeding perch near their nest. The oak this pair selected is at #14 and across the boardwalk from their nesting tree. The pellets and waste on the boardwalk give away the feeding perch's location. Depending on the species and their dietary preferences, the pellets will be composed of differing material. Here in the swamp, the Barred Owls often eat the easy-to-spot-and-catch crayfish. The owl pellet in the image appears to be made up entirely of crayfish exoskeleton. However, in the past, we have found owl pellets on the boardwalk that contained small mammal bones and hair. Additionally, we have observed a Barred Owl catch and eat a Yellow-bellied Sapsucker!

On the topic of sapsuckers, the two in the image spent an extraordinary amount of time chasing each other near the observation tower at Goodsen Lake. Several times, one bird drove the other into the water. They need to be careful...the owls look like they've finished digesting their last meal!

It's Freezing!

Ice in swamp at Audubon's Francis Beidler Forest by Mark Musselman
The staff at the Audubon Center at Francis Beidler Forest knows that there are plenty of places on Earth that are colder than the Lowcountry of South Carolina! However, we are not used to sustained below-freezing weather. Last night was the seventh day in a row with low temperatures at freezing or below, which is one day short of the record set in 2001 at the National Weather Service office at the Charleston airport. The high temperatures remain well below normal. The death of one of the nature center's heat pumps did not help the situation!

Although ornamental plants and family pets need special care during the cold weather, native plants and animals have evolved to handle the natural variability of our climate. Obviously, individuals that are weakened by age, injury, disease, etc. may not survive a prolonged cold snap. Many of our bird species have migrated south to warmer weather and greater food supplies. Most reptiles have found shelter (under bark, below ground, under fallen trees, etc.) that will keep their body temps above freezing. Trees, including the swamp's needle-bearing Bald Cypress, have dropped their leaves and will remain inactive until the warming weather of spring.

Yesterday in the late afternoon, there was still some ice hugging the edge of the swamp or encircling the bases of trees and cypress knees. Meanwhile, Wild Turkeys (Meleagris gallopavo) methodically marched through the upland forest in search of acorns or insects hidden within the leaf litter.

It may be tough, but the strong will survive (especially now that the heat pump has been replaced)!

What's Wrong With This Picture?


The holiday break is over and it's time to get back to work at the Audubon Center at Francis Beidler Forest. Opening today's paper only highlighted how much work still needs to be done. On the front page of the local section, The Post and Courier ran these images with a brief description.


What's wrong with this picture? The caption in the paper left no doubt as it noted that "some dog owners braved the wind and cold Sunday on Folly Beach and released their pets to chase birds..." There is never a good time of year to allow dogs to chase birds on the beach, but certainly not when even dog owners need to brave the wind and cold. The various species of shore birds are hunkered down on the beach conserving energy and avoiding the same wind and cold! Each time dogs or humans flush the birds into the air (remember, it's cold and windy), the birds consume valuable energy they require to survive the winter! Imagine every 15 minutes being rousted from your bed and chased out into your yard to run around in the cold and wind for a few minutes. How many times would you allow that to happen before crying foul? (pun intended)

Enjoy the beach, even in winter, but realize that you are the guest and please respect the residents...they're lives depend on it.

No Christmas Miracle


It's not our imagination, this has been one of the wettest Decembers on record! The rain that moved through Four Holes Swamp last week turned to snow in the Upstate and continued with record-breaking snowfall across the border into North Carolina and on into New England. Enough snow dropped in the latitudes to the north that it will likely be a white Christmas in those areas. It doesn't look like we'll be getting any snow at the Audubon Center at Francis Beidler Forest, but the forecast shows one more dose of rain before December comes to a close.


This month has been the wettest December on record since 1941 with records at the North Charleston airport beginning in 1938. The rain forecast for later this week might be enough to push the month's total to the #1 position in the record books.

December rainfall (National Weather Service office at Charleston airport)
1. 1941/11.08"
2. 2009/9.72"
3. 1953/7.09"
4. 1994/6.35"
5. 1977/5.88"

Not only is the month of December on a record-setting pace, the new record daily maximum rainfall for December 18th was set at the NWS office at the Charleston airport where 3.18" fell thus breaking the old record of 0.95" set in 1948.

What does all this rainfall mean to the swamp? Besides making the swamp actually look like a swamp, it means that there will likely be no Christmas miracle for the Loblolly Pine that has sprouted far from the swamp's edge and the safety of higher ground. The Bald Cypress and Tupelo Gums that constitute the majority of trees growing in the swamp are unaffected by the coming and goings of water. However, this Loblolly Pine seedling stands alone on its fallen-log perch because this and other local tree species are not adapted to stand with their roots in saturated soils. Without the extensive evaporation in warmer weather and with photosynthesis shut down in all but a few swamp-residing trees, the higher water level in the swamp will drop more slowly than at other times of the year, which will cause the Loblolly Pine seedling to endure a more extensive period of submergence.

Although it will likely be wet and not white, have a Merry Christmas!

After the Count

Yesterday, the Audubon Center at Francis Beidler Forest held its first official Christmas Bird Count. The forecasters predicted near 70F weather and mostly sunny by the afternoon. Oops. Not even close...even Maxwell Smart would decline saying, "Missed it by that much."

The fog had not diminish at all by 8:30 am as volunteers and staff headed out to count the twelve sections within the 15-mile-diameter circle in Four Holes Swamp. In fact, the fog did not diminish much by noon, which negatively impacted the quality of birding. The day remained overcast with a light drizzle. Everyone reported having a wonderful time outdoors with friends and new acquaintances, but the bird numbers were certainly lower than they would have been had the forecasted weather materialized! All the reports have not been submitted, but the count totals will be posted as soon as all the reports have been received.

Nothing out of the ordinary was reported with regards to birds. However, volunteers in section #11 (east of Harleyville and north of I-26 in The Bend area) experienced excitement of another kind. Here's an excerpt from their report: There was a resident following me for some time before the officer pulled up behind me. The officer told me that they had been getting lots of calls about people with binoculars. Just before letting us go he told me that there had been a burglary that a.m. with a minivan matching ours at the scene!! Yikes! It took a while to get through that and get back to birding, but it sure woke us up.

Today, the rain stopped and the weather warmed, but the skies are darkening as we type. Radar shows more rain on the way! Canoeing is definitely not a problem in the swamp! Maybe we should go out and give the Eastern Cottonmouth (Agkistrodon piscivorus piscivorus) a "heads up," so that it can get back to the shelter of its winter den.

Counting Birds


The Beidler Forest Christmas Bird Count will be held on Monday. Hopefully, the approaching rain will have moved out by then. The Christmas Bird Count is limited to a circle with a 15-mile diameter. However, a bigger bird count coming in February that can be conducted anywhere by anyone no matter the bird identification skill level!

The Great Backyard Bird Count (GBBC) will be conducted from February 12th to the 15th. From the GBBC site, "The Great Backyard Bird Count is an annual four-day event that engages bird watchers of all ages in counting birds to create a real-time snapshot of where the birds are across the continent and in Hawaii. Anyone can participate, from beginning bird watchers to experts. It takes as little as 15 minutes on one day, or you can count for as long as you like each day of the event. It’s free, fun, and easy—and it helps the birds.

Why Count Birds?

Scientists and bird enthusiasts can learn a lot by knowing where the birds are. Bird populations are dynamic; they are constantly in flux. No single scientist or team of scientists could hope to document the complex distribution and movements of so many species in such a short time.

We need your help. Make sure the birds from your community are well represented in the count. It doesn't matter whether you report the 5 species coming to your backyard feeder or the 75 species you see during a day's outing to a wildlife refuge."


Not only is this something in which students can participate at school, but the GBBC is a tremendous outdoor activity in which the entire family can participate! It is easy to submit the tallies for the birds you could identify. Afterwards, you can see how your region of the state fared, zoom out to see reports across most of North America or see maps for individual species!


Make your plans now so that you are not left out!

Good Walk Spoiled


Mark Twain referred to golf as a good walk spoiled, but today it was the rain that spoiled our good walk across the swamp in Audubon's Francis Beidler Forest.



Once again, we were trying to complete the painting of the cross-swamp internal boundary line. Previously, the futility of painting in the rain caused us to abandon our work. At least then, the swamp was relatively dry and the occasional creek channel was only ankle-deep. With the recent rains beginning to fill the swamp, we knew that we would encounter some deeper water in the creek channels. Additionally, today's high temperature was only forecast to be in the low 50Fs. Based on our wholly unscientific water depth equipment, we report the creek channels as being SOPRANO high!




Although we were unable to complete the boundary painting job, the final creek crossing was more distressing. It wasn't the cool air or the creek's depth, but the fact that we crossed the deep creek just before our lunch break and the rain began to fall steadily as we finished lunch. As paint won't dry in the rain and remain on the trees, we had to head back to the truck, which was on the other side of that deep creek.


As Maxwell Smart was wont to say, "Missed it by that much!"

Four Holes Swamp Christmas Bird Count

On December 14th, Audubon South Carolina will host the first official Four Holes Swamp Christmas Bird Count. Last year, we conducted a test run, which you can read about here.

The Christmas Bird Count (CBC) is a long-standing program of the National Audubon Society that began more than 100 years ago as method of monitoring winter bird populations throughout North America. Each year thousands of volunteers across the United States, Canada and 19 countries in the Western Hemisphere participate in the CBC.

To conduct a count, CBC volunteers follow specified routes through a designated 15-mile (24-km) diameter circle, counting every bird they see or hear all day. It’s not just a species tally—all birds are counted all day, giving an indication of the total number of birds in the circle that day. All individual CBC’s are conducted in the period from December 14 to January 5 each season, and each count is conducted in one calendar day.

The Four Holes Swamp CBC will encompass most of the Audubon's Francis Beidler Forest, Brosnan Forest, and neighboring lands (see the map). Anyone is welcome to participate in the count as we will organize the groups so that inexperienced observers are always out with seasoned CBC veterans. Volunteers will meet at the nature center at 8:00 am to begin and return to the center at 5:00 pm to wrap up the day with some refreshments.

If you are interested in participating in the count, please contact our Director of Bird Conservation, Jeff Mollenhauer at 843-462-2150. There is a $5/person charge to cover costs associated with compilation and dissemination of the CBC results.

Calm After the Storm

On Wednesday, downtown Charleston flooded (not really breaking news), tornado watches were issued, lightning struck, heavy rain fell...not what you want to see the day before a field trip to the old-growth, cypress-tupelo swamp at the Audubon Center at Francis Beidler Forest! No worries! Yesterday, the third graders from Orangeburg Christian Academy in the upper third of Four Holes Swamp's watershed had blue skies, mild temperatures, water in the swamp and more wildlife sightings than the last four groups combined! The weather definitely matters.




We saw an Eastern Cottomouth (Agkistrodon piscivorus piscivorus) before we even reached #1 on the boardwalk. The snake was in the Dwarf Palmettos (Sabal minor), which delineate the transition from the wet swamp to the dry upland. The snake was likely moving to the upland in search of a den site for the winter. One of the sharp-eyed students spotted the motionless snake while the veteran naturalist spoke of the indicative qualities of the Dwarf Palmetto. Not surprisingly, the students found the snake to be of greater interest. In the second image, the entire 3+-foot snake can be seen, but you need to look closely as the snake's yellow-brown-black patterning is perfect camouflage in the broken sunlight.

Once in the swamp, students spotted a variety of woodpeckers, an Eastern Phoebe (Sayornis phoebe) and a Praying Mantid, possibly a female Carolina Praying Mantis. The female praying mantis will mate with a male, if he is able to gain position on her back before being eaten. Even if the male begins the mating process, the female may turn and devour his head before he completes his task. The male's body can complete the mating duties without the previously-consumed head. Once mating has been completed, the female consumes the remainder of the male's body without so much as a thank you! As the female in the image is without a mate, she is likely looking for a suitable site to lay her eggs, which will overwinter in the case of hardened froth. After laying her eggs, the female too will die.


At Goodsen Lake, we were treated to the first alligator (Alligator mississippiensis) sighting in the last three weeks. The warm weather also lured another Cottonmouth out of its cypress-trunk den along the lake's edge. Nothing like a little December sunshine to bring out the cold-blooded reptiles.










The sharp pain in the sinus cavities was a call to check today's weather radar...looks like the swamp's in for another dose of rain.

Seasons Are Changing



The seasons are changing here at the Audubon Center at Francis Beidler Forest. The day began with a brilliant blue sky, temperatures in the low 60Fs, and a gentle breeze coaxing leaves from the rapidly-diminishing canopy. The sky has turned gray and the high temp for the day has already been registered. The weather forecasters are confident that tomorrow will be a windy, rain-filled day. Although these same forecasters have been repeatedly errant over the last few weeks regarding the possibility of precipitation (note soggy school group visits to the swamp or cancellations), a look at the radar image reveals the cause of their supreme confidence. More than a few leaves are destined to lose some feet in elevation tomorrow.


As the temperatures get cooler, there is less food available in the swamp. Some animals migrate to areas with more food, some become inactive or less active (many snakes find a den, alligator will hide on the lake bottom or along the shallow edges), and some cache food for later. The Gray Squirrel (Sciurus carolinensis) on the boardwalk handrail has a hickory nut that it is gnawing open, while another chattered nearby as it searched for the perfect burial spot in which to hide its hickory nut.


A Red-shouldered Hawk (Buteo lineatus) swooped onto a low perch nearby and intently studied the forest floor. From our office windows, we have seen these birds catch various species of lizards and quickly consume the prey. However, our proximity was a distraction and the hawk flew to a much higher perch atop a snag. From there, the bird exchanged calls with another of its species...possibly commenting on the lack of reptilian activity.


Stirred to action by a raucous flock of Ruby-crowned Kinglets (Regulus calendula) in the understory, a Carolina Wren (Thryothorus ludovicianus) easily sang over the noise generated by the diminutive kinglets. Unfortunately, the wren did not sing loud enough to mask the call beckoning us to return inside.












Based on the radar, it looks like we'll be spending tomorrow inside yet again.

Happy Thanksgiving!


The Audubon Center at Francis Beidler Forest is closed today, but we wanted to wish everyone a Happy Thanksgiving!

Turkey is a key component to many Thanksgiving dinners, but the turkey is also a key component of Four Holes Swamp and the surrounding habitat. Wild Turkey (Meleagris gallopavo) often flock together and roost in trees at night. They are non-migratory and often live for only 1.5 years. In 1987, 8 hens, 5 gobblers were reintroduced by Audubon South Carolina, South Carolina Department of Natural Resources, and the Hoover family. The wild birds were were caught in the Francis Marion National Forest and released in the Francis Beidler Forest the same morning. It is not unreasonable to attribute the bulk of local Wild Turkey population to the progeny of the thirteen reintroduced birds.



Occasionally along the boardwalk, Wild Turkeys can be spotted where the boardwalk runs through higher, drier forest (markers 101-116) or where the boardwalk runs parallel to the swamp's edge (markers 154-181). However, as the image shows, the birds are not opposed to walking through the swamp, especially when a crop of acorns have fallen to the ground. If you miss seeing the birds while on the boardwalk, you might see them moving through the fields on either side of our driveway or the roads approaching Beidler Forest.

Enjoy your turkey dinner and we will continue protecting the birds' wild cousins!

iPods on the Boardwalk

Over the last two days, Knightsville Elementary School's 4th graders visited the Audubon Center at Francis Beidler Forest and they brought along some of their iPod Touches.

Using fundsfrom a South Carolina Geographic Alliance (SCGA) grant, we purchased two iPod Touches and accessories. With the two iPod Touches brought by the school, each of the four groups had an iPod Touch as they rotated through the animal (mammal) track activity, an iPod bird call activity and the tour around the 1.75-mile boardwalk. Additionally, two groups used our Flip video cameras to record their experiences in the swamp.



During the animal track identification activity, students used the paper track identification sheet, but also had the option of using the iPod Touch to peruse the various animal track drawings. Images of each animal appeared next to the appropriate track drawing. Even on the best of days, which would not describe either of these two cold, damp days, mammals are not likely to be seen during a walk around the boardwalk. Gray Squirrels are plentiful, but the other mammals (Raccoon, Opossum, Bobcat, Gray Fox, River Otter, White-tailed Deer, Coyote, Beaver, Marsh Rabbit, Feral Hog, rodents, and recently-arrived Nine-banded Armadillo) are mainly nocturnal, secretive, or sufficiently alert to move away from the boardwalk when humans approach. The image of a track and scat was at the Black Bear stop. Although Black Bears are not known to be in Four Holes Swamp, they are in the nearby Francis Marion National Forest and one was hit on I-26 near Jedburg several years ago.


A bird calling station was set up in each of the rain shelters along the boardwalk with each group stopping at one of the stations. Speakers, published bird field guides, Beidler Forest-specific field guides, and other bird identification-related materials were staged at the rain shelters. Using the iPod Touch and speakers, students played an Eastern Screech Owl call attract other bird species within range for visible inspection. Students could use the six S's to narrow the bird species possibilities. Additionally, our two iPod Touch devices contained the National Audubon Society bird field guide app that provided images, content plus a variety of audio for each bird. Once the coding issue is resolved for our Beidler Forest boardwalk-specific app, the same information will be available for use by students and other visitors without the clutter of plants and animals not present or likely to be seen along the boardwalk.


During the tour around the boardwalk, students accessed the extensive library of images showing plants, animals, and maps (boardwalk, watershed boundary, Beidler Forest boundary). With the poor weather and time of year, many animals were not present or not visible. However, as we talked about animals or as students asked questions, the student with the iPod Touch could be tasked with finding an appropriate image to share with the group.

Having the images, content and other data available on the boardwalk when the questions are being asked or the students are looking at the plant, animal, or habitat is a powerful learning tool. It is our desire to obtain additional iPod Touch devices so that we have an iPod for every four students.
