Virtual Toad Detour Training Session

Learn how to protect our toads! Toad Detour protects the local toad population as they migrate to and from their breeding grounds each spring. When the toads emerge from brumation (the reptile version of hibernation) in early spring, hundreds of them cross Port Royal, Hagy’s Mill and other nearby roads to mate in the Roxborough Reservoir or the Schuylkill Center’s ponds. On select nights, when the conditions are just right, Toad Detour volunteers erect barricades and help divert traffic during busy toad crossing evenings, saving hundreds of toads.

Flying Free: Birds at the Schuylkill Wildlife Clinic

Have you ever wondered what goes on behind the scenes at a wildlife rehabilitation clinic? Do you have a passion for birds and want to learn more about helping preserve our native species?

An upcoming virtual gathering sponsored by the Valley Forge Audubon Society, Flying Free: Birds at the Schuylkill Wildlife Rehabilitation Clinic, will discuss the rehabilitation process for avian patients. Our Assistant Director of Wildlife Rehabilitation, Sydney Glisan, will be sharing about what brings these birds in for care, how to help when you find a bird in need, and how to promote coexistence with our feathered friends.

The Real March Madness

It’s hugely exciting times for college hoops fans, awash in basketball games where they breathlessly wait to see if, oh, the Grand Canyon University Antelopes beat the Iowa Hawkeyes, or if Creighton holds off UCSB, whatever that is. Wait, there is a Grand Canyon University?!

Some $1.5 billion will be bet legally over all the new gambling apps, almost 40 million Americans will fill out those brackets, gallons of newspaper ink will be spilled, and sports analysts will natter on for hours. “Bracketology” will trend on Twitter; coaches’ heads will roll. 

Over 19-year-old kids playing hoops. Welcome to March Madness. 

Meanwhile, receiving no fanfare at all, nature in March is simply exploding. Flowers have already begun opening, an elegant parade blooming in an orchestrated sequence begun back in February when skunk cabbages poked through the mud in wet areas, purple mottled hoods protecting a Sputnik-shaped flower. Just this week, the buds of red maples have popped to reveal tiny wind-pollinated flowers, little red spiders dangling from tree branches.  

Red maple

Sure, on our lawns there are snowdrops and crocuses and daffodils and tulips. But our forests will be bursting with ephemeral wildflowers with names as evocative as the flowers are stunning: trout lily, Jack-in-the-pulpit, bloodroot, shooting star, Dutchman’s breeches, Solomon’s seal… With all apologies to the Pennsylvania Horticultural Society (whose show is delayed and outdoors this year—great idea), here’s the real flower show.

Meanwhile, migrating birds are undergoing their own rite of spring, flying through in  progression, red-winged blackbirds and phoebes now, ruby-throated hummingbirds later. Waves of woodland warblers—tiny but unbelievably exquisite creatures wearing extraordinary coats of many colors—pass through like clockwork, pine and prairie warblers right now, blackpolls bringing up the rear at season’s end. And they are passing through in their breeding plumage, essentially wearing  their Sunday best for us. Just Google “Blackburnian warbler”: is there a prettier animal anywhere?

Blackburnian warbler

And while some of these birds are staying for the summer, many are heading to nesting grounds far north of here—think Adirondacks and Canada—only visiting the region for a few days on their journeys north and south. Blink and they’re gone. 

Those birds that nest here—cardinals and chickadees, titmice and robins—will be calling their love songs. One of my favorite sounds of spring is the first moment I hear a wood thrush. A cousin of the robin, the thrush’s song is like organ pipes or flute music: it is simply stunning, and stops me in my tracks every spring. 

Butterflies soon begin awakening, mourning cloaks first, painted ladies soon, swallowtails in late April, and monarchs, just now leaving Mexico, much later.  

Hibernators are crawling out of dens ready to start the new year. Already, painted turtles are basking alongside Fire Pond near the front door of the Schuylkill Center, and American toads will soon be crossing Port Royal Avenue on a dark and stormy night to get to their mating grounds up in the old reservoir across the road. And any day now I expect to see the first groundhog of the season, likely nibbling on roadside grass blades, likely on that high bench of lawn along Hagy’s Mill Road, on the old Water Department land.

That’s the real March madness, that here we are, on the very first days of spring, having survived another wild and wooly winter, having been stuck in lockdown and freeze-down and ice-down, and we’re not betting on the first day a phoebe arrives from the tropics or the first day a mourning cloak butterfly flitters into view. We’re not inviting friends over for a beer to watch our crocuses unfold. We’re not sitting in lawn chairs to admire the red blush of flowers blooming across the maples on our street.

We’re not writing in our brackets which species migrates through first, the yellow-rumped warbler or the great crested flycatcher. 

No, we’re debating whether David, the 16th-seeded Drexel Dragons, can slay the Goliath of Illinois, the Big 10 champions and top seed in the Midwest. (OK, here I relent: go Drexel!)

The struggle for me as an environmental educator is that, as a nation, as a culture, we have collectively decided, quietly but definitively, that college basketball matters. Just look at the air time. The ink space. Heck, coaches’ salaries—in many states, athletic coaches are the highest paid state employees.

But nature? Not so much. Sure, it gets a weekly high-quality hour on PBS, but how are those spring wildflowers doing? How are migrating birds faring? How are those monarch butterflies doing, actually on the bubble as a species? Where’s the Nature section of the city newspaper? The culture has spoken, and nature is far, far down our list.

There’s another part of this madness: nature’s elegant springtime succession of flowers blossoming, trees leafing out, and birds migrating is in disarray because the symphony has a new conductor. While climate change is rearranging ancient patterns to an as-yet-unknown effect, the biggest experiment in the history of a planet…

… we’re glued to TV sets arguing over who’s better, Gonzaga or Baylor.  

So the real flower show has already started outdoors, in your backyard, in a forest near you. But we’re stuck inside filling out brackets.  

That’s just madness.

Nature’s Music At-Home Activities

This week’s nature kits focus on the different sounds that we hear outside. From the calling of birds to the whistling of wind to the crunching of leaves—nature is alive with its own special type of music. 

Every Saturday, nature kits have been given out on a first-come, first-served basis from 10:00 am–12:00 pm. Nature kits focus on a different theme each week and are meant to be done along our trails. If you can’t make it out to the Center to pick up a kit, make sure to check our blog each week for ways to get in some nature exploration at home.

Activity #1: Sound Scavenger Hunt

In our own neighborhoods, there are sounds specific to nature and sounds not specific to nature.

  • Print out a sound scavenger hunt and go on a hike to see if you can hear the sounds on the sheet.
    • As you hike around, pause at a few points and cup your hands around the back of your ear to look like the ears of a deer. This helps to amplify sound or make it louder.
    • Animals like deer and rabbits have large cup-shaped ears so that they can listen for predators such as foxes and coyotes.
    • Which sounds on your scavenger hunt sheet are sounds from nature? Which are sounds that are not from nature? Are there any sounds that you hear that aren’t on the scavenger hunt sheet?
Activity #2: Animal Charades
  • Take a piece of paper and cut it into strips.
    • Brainstorm some animals that make distinct sounds and write (or draw for younger children) one animal on each piece of paper.
    • Put all of the slips of paper in a brown paper bag.
  • Go outside and find the perfect stage to perform your charades.
    • Have one person from your family pick a piece of paper from the brown bag and make the sound that that animal makes.
    • Can everyone else guess what animal it is?
    • Have another person take a turn.
      • For an extra challenge, split your family into teams and see who can get through the most animals in a set amount of time.
    • Which animal sounds were really easy to guess? Which were really hard?
Activity #3: Family Nature Band
  • It’s time to create your very own rock band!
  • Have each member of your family find a nature instrument.
    • Some examples include: using a rock and stick for a drum set, making an xylophone out of different sized sticks, or just grabbing some leaves to crunch.
  • Have one person from your family act as a conductor.
    • When the conductor moves their hands quickly, the music should go faster.
    • When the conductor moves their hands slowly, the music should slow down.
    • The conductor can also tell certain people when to stop or start playing.
      • Point to someone to tell them to start playing.
      • Act as though your hand is a mouth and clamp your fingers together to tell someone to stop playing.
  • Can you put together your own family song?
Activity #4: Jingle Sticks
  • Find a Y-shaped stick in your backyard or a nearby park.
  • Tie a piece of yarn onto one side of the stick.
  • String materials that would make sound through the yarn.
    • Some examples include: dried pasta, beads, or buttons.
  • Once your materials are added, tie the yarn off on the other side of the stick.
    • You can wrap the bottom of your stick in yarn or color it with paint.

 

If you do any of these activities, be sure to snap a picture and share it with us on social media (tag us @schuylkillcenter)—we’d love to see what you discover in your own backyard!

Naughty by Nature: A Valentine’s Day Special

Birds do it, bees do it, and sentimental fleas? Don’t even ask. In a special Valentine-flavored edition of Thursday Night Live, Mike Weilbacher reprises his popular PG-13 lecture on the extraordinarily adaptations and life stories of animals for sex and reproduction. From gender-bending clownfish to overly endowed banana slugs, from giraffe “necking” to male anglerfish hanging around forever, from honeybees to, of course, the infamous praying mantis, you’ll shake your head at the extraordinary antics of the animal kingdom. 

 

Naughty by Nature: A Valentine’s Day Special Event

Birds do it, bees do it, and sentimental fleas? Don’t even ask. 

In celebration of the coming Valentine’s Day holiday, the Schuylkill Center cordially invites you to a special edition of our new Thursday Night Live series. “Naughty by Nature” features the amazing stories of sex and courtship in the animal kingdom, as these stories are extraordinary and just not shared often enough. I’ll be offering this PG-13 lecture on Thursday, February 11 at 7:00 p.m. The event is free, but you’ll need to register and get the Zoom link. 

Animals possess a wide range of adaptations to court their mates. So lion manes, buck antlers, firefly flashes, cricket chirps, cardinal songs, and peacock feathers—among many others—are all adaptations to seduce females. Let’s start with those buck antlers.

The antlers give a female strong visual cues as to the health and vitality of the male—the size of the rack matters, and as bucks mature the antlers tend to get larger and larger. But the story doesn’t stop there. Many times on autumn walks around the Schuylkill Center’s trails, I’ve come across a buck’s rut, a scrape in the ground made by the male. He not only scratches the ground clear of grass, but urinates down his hind legs, the urine mixing with hormones secreted by glands in his knee joints, and a witch’s brew of liquids puddles in the mud. The does find the smell, well, irresistible. He has staked out his turf, laid down his calling card—and likely will find does there the next evening. This system works exceptionally well, as just about every doe is pregnant by the time winter settles in. 

Let’s swim over to the clownfish, the brightly colored star of “Finding Nemo.” Well, surprise, the movie got it all wrong. In much of the animal kingdom, gender is relatively straightforward; an organism is oftentimes born or hatched as male or female. Bucks are bucks; does remain does. Not so among clownfish.

Clownsfih have this marvelous adaptation of being immune to the stings of the sea anemones that live alongside them in coral reefs. The clownfish uses the anemone as  protection, making it harder for those hungry moray eels to get them. A small cluster of clownfish live in and around one anemone, a little community of clowns cloaked by anemone tentacles.

But two of the clownfish are larger, one male and one female, and these are the two that mate; the others are not only celibate, they are all male. Let’s say that moray eel gets lucky, or old age catches up to the female, and she either perishes or is someone’s dinner. What then?

Easy. Turns out clownfish, like a surprising number of fish, are sequential hermaphrodites, possessing the sexual organs of both sexes but suppressing one until needed. In the sudden absence of a female, the large male shifts his sex over and becomes the new female; the remaining smaller males then jockey for position, with usually the next-larger male winning the right to be the new dominant male, bulking up rapidly in size to take his position atop the sexual food chain. Situation solved. 

Or let’s see how bees do it, as the song notes. Most of the honeybees you have seen in your life are female workers. There are male bees, the drones, but these bees do not work: they gather no nectar, make no honey, clean no queen, raise no brood. They have only one, albeit important, reason for being, a singular task to accomplish: they are living sperm containers waiting for a virgin queen to fly. They are flying insurance policies.

And somehow the drones of neighboring hives all know where to congregate—they all get an unwritten memo and map in a secret code that scientists have yet to crack. And there they wait… 

So when a new queen emerges from her special queen cell in the hive, her first task is to scour the hive looking for other queen cells, as hives with an aging queen likely raise multiple new queens to make sure one works out. The first queen that hatches then kills the others immediately; sororicide, the killing of sisters, is her very first act.

Her next act is to tank up on sperm. To do that, she flies to those same drone congregation areas; she’s got the map as well. And the fastest, maybe the luckiest, male who catches her first mates in mid-flight. Unfortunately for him, copulation results in death; he immediately falls to the ground as the climax to her nuptial flight, and she has the sperm she needs for a lifetime of egg laying.

Those drones are also incapable of feeding themselves; they beg for food in the hive by tapping on the antennae of female workers who obligingly regurgitate food for them. Until the fall. As the hive slides towards winter’s lean season, no nuptial flights will be occurring and the hive needs its honey to survive the winter. Now, drones are expendable. So when the males tap females for food, the workers deny the request, and the drones starve. They die in the hive, and are carried out by female undertaker workers to be unceremoniously dumped outside the entrance. Ah, love.

So calling all bucks and does, or even stags: join me for a lively evening discussing the delightful and surprising sexual antics of the animal kingdom, just in time for Valentine’s Day.

At-Home Nature Exploration: Animals in Winter

COVID-19 has forced the Schuylkill Center to pivot and reimagine many of our programs. At the beginning of September, we began to reinvent our popular Schuylkill Saturday program so that families could explore our trails through self-guided activities available in Nature Kits. Every Saturday, Nature Kits have been given out on a first-come, first-served basis from 10:00 am–12:00 pm. Nature kits focus on a different theme each week and are meant to be done along our trails. Since the start of our nature kit program, we have seen more than 800 people come out and have handed out over 450 kits.

Starting this week, we are going to be featuring at-home versions of our popular Nature Kit activities so if you can’t make it out to the Center to pick up a kit, make sure to check our blog each week for ways to still get in some weekly nature exploration right where you are.

 

Animals in Winter

In the winter, temperatures drop and it gets really cold. In order to survive, animals will do one of three things: hibernate, adapt, or migrate. Animals such as bears and chipmunks will hibernate. This means that they curl up in a warm place, such as a cave or tunnel, and stay there until winter ends. Other animals, such as fox and deer, will adapt. To adapt means to use a special feature, such as a thick fur coat or stored food, in order to survive the cold temperatures. Lastly, to migrate means to travel to a warmer spot. Animals such as birds and even some marine mammals will migrate. Follow the directions for the activities below to learn more about hibernation, adaptation, and migration.

 

ACTIVITY #1: Squirrels and Adaptation

Squirrels are examples of animals that adapt in the winter. To stay warm in the winter, they will spend more time in their nests and less time out foraging—similar to us staying inside when it gets cold. Before winter starts, they will also bury food such as acorns. It can be hard to find food in the winter so squirrels will return to these stashes of food for something to eat throughout the winter.

  • Draw a number of acorns on a piece of paper (Tip: Put a paperclip on them if it’s a windy day!)
    • Hide them in either your backyard or a nearby park.
    • Wait 5-10 minutes—and then see if you can find them all again.
      • If you have real acorns around, you could do this same activity with real acorns—just make sure to mark them in some way (ex. wrapping a piece of yarn around them) so that you can tell them apart from other acorns. 
  • Take a moment to look around your backyard or a nearby park to see if you see any squirrels out and about.
    • Are they digging up acorns that they buried before the winter?
    • Try looking up in the trees for squirrel nests. Squirrel nests look like large bundles of leaves balanced between tree branches. They are often easier to see in the winter when there are no leaves on the trees.
ACTIVITY #2: Birds and Migration

Birds are an example of an animal that migrates. Birds migrate to warmer areas to find food and lay their eggs. Birds, however, often face challenges as they migrate. They rely on areas such as wetlands for food, rest, and shelter—similar to how we stop at rest stops and hotels when we travel. These areas though are oftentimes developed to make way for houses or shopping centers. Grab a piece of chalk and make a hopscotch board on a nearby sidewalk.

  • Take a moment to look around for birds in your backyard or a nearby park.
    • Although many birds migrate, some do stick around in the winter and will often change their diet depending on what foods are around.
      • For example, birds that eat insects in the spring and summer may switch to eating more seeds, nuts, and berries in the winter when insects aren’t as readily available.
    • What type of food do you see that is still around for these birds?

 

ACTIVITY #3: Bears and Hibernation

Bears, chipmunks, skunks, groundhogs, and snakes are all examples of animals that either enter true hibernation or something similar to it. Animals that hibernate usually find warm areas such as tunnels, burrows, or caves.

  • Make a warm den outside for a stuffed animal that you have at home.
    • Try to find a small crevice and use natural materials such as sticks and leaves to make it nice and warm.
    • Besides warmth, try to think of some other features that would make for a good den (ex. shelter from rain or snow, hidden from potential predators, etc.).
  • Take a moment to look around in your backyard or a nearby park. Can you locate some areas that would make for good places for animals to seek shelter or cover?

 

If you do any of these activities, be sure to snap a picture and share it with us on social media (tag us @schuylkillcenter)—we’d love to see what you discover in your own backyard!

News Flash: Beavers in Roxborough!

One of the feel-good stories on the environmental scene is the rewilding of large cities like Philadelphia, where suddenly peregrine falcons nest in church steeples and on Delaware River bridges, bald eagles pull large fish out of the Schuylkill River, and coyotes amble down Domino Lane.

In that vein, members of the Roxborough-Manayunk Conservancy were somewhat startled to discover that the restoration plantings they’ve doggedly placed along the Schuylkill River have been devoured by…beavers! Wait, beavers in Roxborough?

Once extirpated—a fancy word meaning locally extinct—across Pennsylvania, hunted because their fur was remarkably valuable and because we did not appreciate their ability to rearrange landscapes to their own ends. But beavers have been returning to our state over the last century, and have been seen along Tacony and Pennypack Creeks since about 2008. And now they have taken up residence in the Schuylkill River and Manayunk Canal around Flat Rock Dam.

“I first noticed beavers and their lodge in the winter of 2018,” observed Suzanne Hagner, Roxborough resident and member of the Roxborough-Manayunk Conservancy, “as I rode out the Schuylkill River Trail towards Shawmont. I could see where they had worn down a path into the woods on the far side of the trail and I guessed that was where they were going for food.” The lodge was near Flat Rock Dam, and they have been spotted—and photographed—as far down as Lock Street and as far up as past Shawmont Avenue, both in the canal and along the river.

“You can see their work from Lock to Cotton streets,” added Kay Sykora, another key Conservancy member, “particularly in the Cotton Street area; look for the damage on the banks and trees.” She offered that there was a “small dam in the wetlands near the upper locks” but that may have been damaged by heavy storms. Tom Landsmann, president of the Conservancy, offers that “the very best place to see the beaver or signs of the beaver’s visits is from the river. Take a kayak or paddle board and look for the damaged bark or the lodges. Look just above the flat rock dam on the Philly side, but on the Lower Merion side and up river as well. Can’t miss it.”

They famously cut down saplings and trees with their chisel-like teeth, building dams and lodges with the branches, chewing the inner bark of trees as their favored food source. That tree-cutting, of course, can sometimes interfere with our own good work.

“Beavers have good taste in trees,” Tom added, tongue in cheek. “They ate over 60 trees we planted along the canal last year. But we adjusted. Last spring, we painted the uneaten trees with latex paint mixed with a lot of sand,” the grit distasteful to the large rodents. “Many of the damaged trees grew out again this summer,” he continued. “We wrapped those trees in cages this fall. We installed 130 cages along the canal near both sides of Fountain Street.”

Bernard “Billy” Brown, author of Grid magazine’s Urban Naturalist column, told me that, in addition to the cages, Riverfront North, a group doing restoration work along Pennypack Creek, “has planted species that can rebound well after being cut down by beavers, like willow species in particular.”

The Conservancy recently hosted a walk-through of the area with a self-described “beaver believer” they brought in from central PA, and their takeaway was similar. “The other approach which I believe we will have to do,” continued Kay, “is to rethink our plantings. We need to put in more herbaceous plants on the impacted banks and see if we can add things like willows to the upper wetland areas to keep them in that area, which is better suited for them and for us.”

Suzanne Hagner agrees. “There are plants, several species of low growing willow that beavers eat that we can plant and hopefully, if we get them planted soon, we can entice the beavers to move further out the trail” and away from their restoration plantings.

Billy Brown has been writing about the beaver’s return to Philadelphia for a while now. “As a reaction, I’ll say that beavers and their return to Philadelphia show the importance of waterways in connecting urban habitat with the surrounding landscape. I think most people under-appreciate how severely our system of roads isolates habitat, an issue the Schuylkill Center contends with the Toad Detour project, for example. Waterways and the green corridors around them are exceptions to the fragmentation of habitat in urban landscapes. The ability of beavers to quickly disperse through the city shows that. It’s both tantalizing and frustrating to imagine how different our urban ecosystems would be if we could more broady connect to the surrounding landscape.”

Suzanne Hagner has been reading up on beaver, passing books along to Conservancy members. “They are amazingly skilled at creating waterways and irrigation systems that lead to ecological health,” she said. “Our consultant offered that the return of the beavers was a very good sign in our area, as the beaver is an ecological system in itself. I had lived in Washington state, and had heard that beavers were being reintroduced in eastern Washington to help curb the arid areas that are prone to wildfires.”

“The return of the beaver,” notes Kay Sykora, “along with a wide range of wildlife like herons and turtles underscores the health of our river area, once one of the most damaged and polluted rivers in the country. Beaver were virtually trapped out of existence for their fur, and there was no understanding of the role they played in the environmental balance of nature. They are key to the health of our wetland areas and the range of wildlife that needs those areas to survive.”

Go for a walk along the Schuylkill River Trail, and find for yourself the pointed chiseled ends of tree trunks along the canal and river. It’s evidence of Roxborough’s newest neighbor, the beaver.
