American Toad

Anaxyrus americanus  (formerly Bufo americanus)

Reptiles Alive Name: Tony & Walker

Hissstory: Tony was found on RA Wildlife Educator Tony’s driveway in May of 2009.  Walker was found in the RA tortoise yard in August of 2010.

RA Diet: Meal worms, crickets, and earthworms.

Natural Diet: Insects and small animals including baby snakes and other frogs.

Range: The northeastern and mid-Atlantic United States north into Canada.  American toads are native to the Washington DC area.

Habitat: Toads can be found nearly anywhere there is shallow water in which to breed including suburban and urban parks, yards, and gardens.

Size: On average. American toads grow  2-3.5 inches, however, the largest on record was 4 and 3/8 inches.

Lifespan: Can live up to ten years.

Reproduction: Toads breed March-July. Females choose the males with the best song.   She then lays the eggs in long spiraling strands in vernal pools and roadside ditches.

Conservation: If you have a toad living in yard, consider yourself lucky!  Toads provide pest control by eating a huge amount of insects daily. One American toad can eat up to 1,000 insects every day!!  Protect toads you find and provide shelter for toads in your yard to encourage them to stay.

Cool Facts: You can’t get warts from touching a toad – but you can get poisoned!  The warts on a toad’s body are actually poison glands.  When a toad feels threatened, thick sticky white poison will ooze out of the warts.  The poison isn’t strong enough to seriously hurt a human – but if you eat a toad, you will probably get a bad stomachache.  So, don’t eat toads!

There is a mysterious area very near to that place which is known as Washington DC. It is an area as vast as about  1 or 2 square miles and as timeless as infinity (or at least a few million years.) It is the middle ground between light and shadow, between city an country.  Journey with us now into this wondrous land. It is an area which we call the: “Hognose Heaven Zone.”

Our story begins with a foursome of herpers, Caroline, Charise, John W and Jon K, hiking to an undisclosed location near Washington DC.   Years before this journey began, former Reptiles Alive Wildlife Educator and Keeper Jeff Stryker discovered  a population of hognose snakes and eastern milk snakes (two awesome snake species that are not very common in the suburbs) living in this strange spot and named the place “Hognose Heaven.”

As the group’s journey began, they spotted their first herps of the day. There were many turtles and frogs living in the wetlands along the trail.

Soon, the  group of herpers veered off the main trail onto a little-used trail that led to the heart of Hognose Heaven. They began turning over logs and rocks.  A four-toed salamander was discovered!  The salamander’s creamy white and black spotted belly helped with its identification.

After arriving at Hognose Heaven, something very unexpected appeared to materialize out of the rocks, sticks, and leaves – something that even four experienced naturalists could hardly see until they were right on top of it!

The fawn was only a few hours old. Its camouflage was remarkable! The baby deer was nearly invisible – the perfect survival strategy for a small animal that can not yet walk or run. Its mother was nearby and would return as soon as the coast was clear. Even though the group was in a strange place, it is normal to find fawns alone in the woods without their mother. As soon as the people vanish, the mother deer will come back to care for her fawn.
After observing the baby deer, the group continued searching for snakes. Caroline quickly found the hognose snake’s favorite food item: toads.

As Caroline approached John W to inform him of her find, she noticed he was holding something in his hands. Something about 3 feet long, with orange spots on a black body and a pointy, upturned nose. “Hognose! Hognose!” she yelled with joy!

John W and Caroline yelled for Jon K and Charise to come and see the spectacular serpent. When they arrived, however, the snake was acting strange.

As the group excitedly discussed the behavior of the hognose snake, the snake in question seemed to miraculously get better!

After making his miracle recovery from his apparent death, the snake made his move and slithered back to the safety of his rocky home.

Now, the group needed to make a decision. Continue the search? Or have lunch? Caroline suggested having lunch after a short hike over to a nearby bizarro-world she called: CACTUS ISLAND!
Believe it or not, (believe it), the prickly pear cactus is native to the Washington DC area. Much of its habitat has been lost to urban development, but it can still sometimes be found in certain micro-habitats around our nation’s capital. That day, the cactus was in bloom!

Does the story end here? Did they find an eastern milk snake? Did they have a good lunch? Only they know the answer to those questions. Questions from the Hognose Heaven Zone.

We had a ssssspectacular Saturday as part of a Virginia Herpetological Survey (VHS) team for Mason Neck State Park and National Wildlife Refuge.  Tony & Caroline along with about 20 other VHS members participated in the day long search for reptiles and amphibians.  Each animal found was documented along with the location and  micro-habitat it was found in.

We started the day around 8:30 am.  We were divided into 5 teams that were given 5 different sections of the area to survey.  Our team was assigned to the areas of the Wildlife Refuge that are closed to the public.

We drove to the end of the main Refuge access road to an area that used to be a farm.  Five foot tall grass, poison ivy, and millions of deer ticks awaited us.  We were not deterred!  Almost immediately an eastern box turtle was found.

And then in a very short period of time, we found a brown snake, multiple worm snakes, more box turtles, two spotted salamanders, and giant native millipedes (I know – they don’t really count on a herp survey, but they were so cool!)

We also found two black racers – snakes that are known for being fast.  One of the racers was in a somewhat odd micro-habitat.  It was about 5 feet off the ground hanging on a small tree growing on the edge of a cliff.

We continued herping (searching for reptiles and amphibians) throughout the morning.  It was hard work hiking through the brush, lifting logs and turning over rocks, but we were dedicated to our mission.

We drove a few miles down to an area of vernal pools, marshes, and wetlands.  We found more herps, including cricket frogs and green frogs.  One of the green frogs was also in a somewhat strange spot (for a green frog), he was about 3 feet up on the side of a tree stump.

While in the wetlands, we also found some frog predators.  Many painted turtles were spotted basking on logs.  A large snapping turtle was found in a pond under a log – but he foiled our attempts to take his picture.

Many people believe the myth that venomous cottonmouth (water moccasins) live in the Washington DC area.  They do not.  Our area is too far north for them to survive.  We do, however, have harmless northern water snakes which are often confused with both cottonmouths and copperheads.  Like many snakes, northern water snakes will flatten their bodies and heads to appear more “viper like” when they are threatened which can lead to their mis-identification as a venomous species.

In the same wetland location, we also found beautiful ribbon snakes.  Ribbon snakes are similar in appearance to their close relatives the garter snakes, but the ribbons are much more slender.

Whew – after all this success we started to get a bit hungry.  So we decided to head back to the meeting site,  eat lunch, and find out how the other teams were doing.

After our short lunch break, we headed back out into the field for more searching.  We discovered more worm snakes, more box turtles, lots more green frogs, more spotted salamanders and we had an encounter with a rarely seen in Fairfax County lizard species, the ground skink.

Deep in the woods, far from any roads or trails, we also discovered a sign of the past.

No copperhead snakes were found during the entire survey.  Over 40 dedicated reptile specialists searching a large area of protected forest and no copperheads.  This is actually normal.  Copperheads are not nearly as common as some people believe.  Copperheads are also shy and afraid of humans.  They will only bite if they feel threatened.  So, you know, leave snakes alone.

We did, however, find a venomous species of arachnid hiding under a log:

Around 5 pm, we headed back to meet up with the other teams and share our data collection for the day. The VHS president Kory Steele was there adding up all the numbers from each team. Soon, we would learn which team found the most animals.
Guess which team won? Well, as Kory reminded me, this was not a contest. Our mission was to collect data to assist with the conservation of reptiles and amphibians. (Ok, but our team won – we found 57 individual herps representing 17 species – woo hoo woo hoo!)
All of the animals we found that day were left in the spot we found them. Well, except for two animals – alien invaders were found in a turtle sampling trap.

The aliens were the Frankenfish – the Northern Snake-head! Apparently, there is now a large breeding population of these introduced exotic fish in the Potomac River and its tributaries in the Mason Neck/Pohick Bay area. This new invader could cause unknown consequences on our native fish, reptiles, amphibians, insects and possibly even birds and mammals. Surveys such as the one the VHS teams completed at Mason Neck are crucial for the protection and conservation of our wildlife.
We had a sssssssuper ssssssssuccessful Ssssssssssaturday. It was snaketacular.

Last weekend we had some beautiful early April weather here in Northern Virginia.  After our brutal winter – we deserved it!  We headed out to Hemlock Overlook Regional Park to look for some signs of herpetological spring.  And we found it!

Our first find was one of the most common vertebrate creatures in the eastern United States:  the red-backed salamander.

Red backed salamanders come in three different colors:  red backed, yellow backed and black or “lead” backed.

Red backed salamanders are different from many other amphibians.  They are members of the lungless group of salamanders – so they get all their oxygen absorbed into their blood stream through their slimy skin.  They also lay their eggs on land and the the larvae go through metamorphosis in the egg.  So, red backed salamanders never have to leave the land to lay eggs in the water the way most amphibians do.

Toads, on the other hand, must return to the water each year to mate and lay eggs.  At Hemlock, the woods were alive with the pleasant music of male toads singing to attract females.

The male will “hug” the female (the science word for this toad hug is amplexus), and the female will lay hundreds of eggs encased in gelatinous goo into the water.

In a few weeks, the temporary pools in our area will be filled with millions of black tadpoles that will quickly grow tiny legs and metamorphose into tiny toadlets.  To attract insect and slug eating toads into your garden, consider adding a toad home

We did not find any snakes on our trip at Hemlock, but the next day, one of Caroline’s neighbors called her to come and get a visitor out of her bathroom.

Yep, I would definitely say that herpetological spring has sprung!

After the snowiest winter in Washington’s recorded history, the amphibians have finally made their way to the vernal pools to signal the beginning of spring. They are bit later than usual in this area. Late February is typically when spring peepers, wood frogs, and spotted salamanders make their first appearance in the DC area. This year, due to abnormally harsh winter conditions, they were about two weeks or so behind.

Last Friday night a few of the team members from Reptiles Alive had the special opportunity to visit a wetland area that is usually off-limits to the public. Off limits because it is behind a shooting range! We were invited by master naturalist Greg Zell along with a handful of other professional herpetologists and naturalists.

We met up at dark in the cool rain. Perfect weather. Well, maybe not perfect for humans, but definitely perfect for amphibians! On the road into the park, we discovered our first amphibians of the night – American toads!

After putting on our rain gear, we crossed the shooting range walking over millions of broken clay targets until we reached the wetlands.  Immediately someone yelled “Spotted!”  Then more shouts were heard, and we realized, we were in the middle of hundreds, possibly thousands of spotted salamanders!  It was AWESOME!  They were everywhere!  Large female salamanders were being surrounded by 5 to 10 males at a time.  Salamanders were almost everywhere you pointed your flashlight, crawling through the mud or swimming like fish in the cold, clear water.  After an hour or so, spermatophores from the males began to fill the water as the ancient amphibian breeding rituals took place. It was the most amazing salamander sight I have ever witnessed.

We spent a few hours observing them, photographing them and discussing them before we all decided it was time to come in out of the rain and dry off.  A few of us headed to Dogfish Head to warm up and have a late night dinner, but that, is another story…

I had heard stories of the black flies that live in the north, but I never believed that they could be that bad.  I was wrong.  I am trying unsuccessfully not to scratch as I write this.

Last week I went with my Dad and Kay to Mont Tremblant, a mountain resort area in Quebec, Canada.  It was a fantastic place, full of gorgeous rivers, lakes, and mountains.  We went fishing for trout, hiked on great trails, and ate LOTS of fantastic French food.

The area is full of lakes carved by glaciers that retreated long ago.  The lakes are full of frogs and fish.  I saw green frogs and heard their calls, along with the calls of gray tree frogs, bull frogs, and spring peepers.  I did not see any reptiles, but I was lucky to catch a speckled trout on our fishing expedition.  During our time on the boat, there were no insects to be seen (or felt).

I was on the dock of a very nice restaraunt, petting a cat, when I had my first real taste of what black flies are capable of.  They were swarming all around my face and head.  I brushed them away and figured they were kind of like gnats – annoying, but basically harmless.

I went back inside the restaraunt to place my order for dinner (grilled venison, yum!), and noticed I was bleeding around my chest and neck.  The waitress who spoke mostly French, noticed, and began to explain what black flies can do to a person.  She said they liked to crawl under your clothes and hair where they bite throught your skin ans suck blood.  Their bites will cause bleeding, then later, the bites swell and become very itchy and in some people, very painful.

I excused myself from the dinner table, went to the restroom and shook all my clothes out.  I then noticed that I was bleeding from many, many bites on my face, neck, and back.  It was a bit gross.  After the bleeding stopped, I went back to the table and enjoyed a dinner that was magnifique.

A day later, all of the bites had turned into large red welts that itched like mad! I knew I had to avoid getting any more black fly bites.  I now had respect for them.  These were no gnats!

It turns out, black flies breed in clean, fast running creeks and rivers.  The larvae cannot tolerate pollution or still water.  The larvae and adult flies are a major source of food for trouts, birds, and many other insects and animals.  The adults typically come out around mid-May and stick around until the end of July, but the actual “black fly season” depends on location and weather conditions.

Black flies are a major problem for livestock.  Because black flies like to crawl inside nasal passages, cattle an other livestock are sometimes smothered by the swarming flies.  The flies can also spread disease and cause such stress to animals, that they die.

I had a great time in Canada – and I would love to go back.  But this time, I’ll remember to bring the bug spray!

Memorial Day was a particularly busy day, herpetologically speaking.  I started the day in my garden with a cup of coffee and a Northern Brown Snake basking on top of some thyme.  I was careful not to disturb the little foot long snake, and he seemed happy to hang out.  I love having brown snakes in the garden since they love to eat slugs and snails.  I also just happen to like snakes in general.

As Rachel was getting ready to drive in to work, she spotted her neighbor about to hurt a Black Rat snake that was in his front yard. Luckily, she was able to save the snake and move it to the woods in the back of his property.  Black Rat snakes help control rodent populations and are not dangerous to humans in any way.

Later, while Rachel was loading animals to go to her show, she heard our next-door neighbor scream!  She asked if he was ok and he said he just saw a snake in his golf bag in the garage and would she please come and get it.  Rachel had to leave so she would be on time for her reptile birthday show, so she came and got me.  I went over to my neighbor’s and found the 4 feet long Black Rat snake hiding behind a shelf in the back of his garage.  I gently picked it up, carried it to the bushes in my front yard and released it.

Whew – but that was not all!

As usual, I saw the Five-lined Skink lizards that live in the my compost area.  These beautful blue, yellow, and brown striped lizards are fantastic insect hunters and are a fabulous addition to any garden.  They are also fun to watch.

The grand finale of the reptile day was in the evening.  We had a Reptiles Alive Memorial Day barbecue with Jen Pennington, Jen Rafter, Rachel and a few other friends and family members.  As Rachel was walking in the garden, she found a young Eastern Box turtle!  We all looked at the turtle and noted how young and healthy it looked before returning it to the garden.

So, to review, in one day in one neighborhood we saw:   One Northern Brown snake, one Black Rat Snake, two Five-lined Skinks, one Eastern Box turtle and Rachel saw one more Black Rat snake in her neighborhood before she came to work.

Gardening for wildlife is becoming increasingly popular.  Most wildlife gardening information is geared towards attracting birds, bees, and butterflies.  At Reptiles Alive, we also like to garden to attract frogs, toads, snakes and other creatures too.

If you want to attract some awesome critters into your yard, here are some really easy steps you can take.

One of the easiest ways to attract wildlife is to do nothing! That’s right – just let a part of your yard go wild.

Birds, snakes, frogs and box turtles all love to live in areas that humans ignore.

Remember when mowing, trimming, or doing yard work to watch out for small creatures like snakes, turtles and bunnies.

When choosing plants, picking plants native to your area will encourage native animals to take up residence

.

Leaving fallen logs can give salamanders, worms, and small snakes a place to live.

Rocks can add beauty to your garden and provide shelter for snakes, spiders, toads, and more.

Adding a small water feature like a bird bath at ground level can attract not just birds, but many other animals as well. Just be sure to change the water every couple of days so you don’t add more mosquitoes to your yard.

Even a vegetable garden can provide habitat for animals. Under the straw covering this asparagus bed, I find brown snakes and toads.

Here’s a Reptiles Alive secret: My Dad introduced me to my first snake when he was lifting straw off the potatoes in our garden. I was 4 years old. I decided at that moment in our garden that I was going to be a herpetologist when I grew up.
So, who knows where gardening can take you?

Officially, spring does not actually begin until the Vernal Equinox on March 20.  However, there are many signs of spring popping up all over the Washington DC region.  The cheery blooms of the forsythia, crocus, and daffodils  can be seen in neighborhoods across our area.  But what gets me excited is the beginning of herpetological spring – when the spotted salamanders, wood frogs, and spring peepers begin to emerge.

Most of the year, spotted salamanders and wood frogs remain hidden from view buried under ground or hiding under fallen leaves in the forest floor.  But once a year in late February, March, and early April, we have a chance to actually see these awesome amphibians – and not just one or two, but lots of them all at once!

Thousands of spotted salamanders, wood frogs, and spring peepers all head for vernal pools at the same time.  Vernal pools are ponds of water that dry out in the summer, so no fish can survive in them.  These pools are crucial to the survival of many species of insects and animals, including many amphibians.

The salamanders and frogs lay millions of jelly-like eggs in the vernal pools.  Within a few weeks or so, the eggs hatch into larvae, or tadpoles.  The tadpoles go through metamorphosis fairly quickly so they can leave the water before the pool dries up.  The froglets and tiny salamanders emerge from the water and almost immediately disappear into the surrounding woodlands – not to be seen again until next year.

So, last weekend I convinced my friend Jon Kerr to head out with me to some of my FAVORITE froggy places.  A very strange vernal pool can be found in Fairfax County at Scott’s Run Nature Preserve.  This “vernal pool” is actually an abandoned swimming pool that was built using a natural spring as a source of water.  Even though humans have long since abandoned it, the pool is now used by hundreds of wood frogs and spotted salamanders every year.

When we arrived, the place was hopping! With wood frogs that is! But there were no spotted salamanders to be found. They were probably still on their way – they just needed a rainy night to really get them going. We did, however, find a pinchy crayfish in the nearby spring seep.

Next, we headed for Eakin Park – one of my favorite places to be.  You can sit and listen the amazing loud songs of the teeny Spring Peepers.  This is my most favorite sound of spring – I LOVE this time of year!
