Amphibians are bellwethers for us–they let us know what conditions are like in our wetlands. Worldwide, they don’t seem to be faring well. According to Amphibiaweb, in the last 20 years or so, 168 amphibian species have gone extinct–you know, disappeared forever. Almost 1/3 of amphibians are threatened with disappearing the world over. Fatal fungi and habitat destruction seem to be the gravest threats.

With the possible exception of the Egyptians who encountered the Hebrew prophet, Moses, most people like amphibians. 07EXODUS3-master675-v2

Depending upon where you live you might have frogs and/or toads, salamanders, or even caecilians as neighbors.

The one thing that ties all amphibians together (OK, perhaps there is more than one thing) is their double life: exisiting on land and water.

Some of them, like caecilians, which includes sirens, spend their entire lives in water. Others, like toads and some salamanders, use aquatic habitat primarily for breeding. Frogs, probably the most recognized amphibian, can be found on land and in the water throughout their adult life-span.

I’m going to focus on toads for this post because…they are found in my neighborhood–my backyard even.

Michigan has two species of toad: the Eastern American toad (‘Merica!), Bufo americanus, and the Fowler’s toad, Bufo woodhousiifowleri. The latter is found along the western third of the lower peninsula, whereas the Eastern American is distributed everywhere, including the U.P. (Upper Peninsula). It’s also found in eastern Canada, and of course, the eastern U.S.

Toads, if you didn’t know, have dry skin and can be gray, brown, reddish-brown, tan, or even olive. Their backs have dark spots, and at times dark spotting is on the throat and belly, but usually that area is whitish or yellowish. Adults are generally anywhere from two to four inches in length–though I saw a giant toad in Canada once (perhaps my tiny boy eyes made the beast appear larger?).

Probably the toad’s signature identifier is the appearance of warts along its back and head. Their short legs, though the hind ones are longer than the front, give them a squat look. Combine squat and warty and you get Sqwarty. That sums up a toad–Sqwarty. Ranging in length from two to over four inches, toads are smaller than many of their frog cousins. That makes them easy to step on, unfortunately.

What’s for Dinner?

Toads won’t eat your crops. They are insectivores and expand their palate to include spiders and earthworms. Supposedly, they can consume 26 insects a day for a total of 3,200 from May to August. Not quite as prolific insect devourers as bats, they still provide ecosystem services pro bono.

Where to Look

     If you look in open woodlands and the edges as well, you might find a toad–or multiple ones. If you look in meadows, marshes, lake shores, and even your backyard, you might find a toad.

During hot, dry periods and during winter they are buried in moist soil or plant debris. How did they get there? Toads can dig holes with their hind feet.

Toad Love?

The season of love for toads is in April or May (it began in my neighborhood on April 9th of this year) when they begin moving to wetlands.

That irresistible sound that boy toads make is a high, sharp trill that can last up to 30 seconds, which comes from an inflated throat sac.

Toad sex is called, sexily enough, amplexus. The male clasps the female from behind her front legs and then fertilizes anywhere from 2,000 to 20,000 eggs which emerge from her body in long, gelatinous strings that attach to submerged rocks, plants, twigs, hot tubs, whatever.

Depending on the water temperature, tadpoles will hatch 3-14 days later. The pre-toads eat algae, plant material, and the dead, but not mosquito larvae unfortunately. In about 6-10 weeks they transform into toadlets and take about 2-3 years to reach their massive 2-4+ inch adult size.

Pre-toads…

…to toadlet.

 

 

 

 

 

 

 

Please Don’t Eat the Toads

A toad’s coloring and texture help camouflage it in it’s surroundings. Failing that, they can secrete an icky substance from their back warts which can be toxic to small mammals if ingested. Plan C  is to inflate with air to prevent something swallowing the toad. And if you still insist on picking them up, they’ll probably urinate in your hand.

 

Did You Know…?

  • Toads are found on all continents except Antarctica
  • A group of toads (what’s the minimum number? I. Don’t. Know.) is called a knot
  • They have no teeth
  • According to my sources they are nocturnal, but I’ve found plenty of toads in the daytime. The mating call does tend to start around dusk, however.
  • The lucky ones can live for 20-40 years
  • While you can find them near water when it isn’t mating season, they’ll generally be found in drier areas.

Toads have made it into 20th Century pop culture:

A series of stories for early readers–something from my childhood.

I didn’t read this as a child, but I did read it to my son.

Everything gets appropriated by Disney!

  • Have you ever held a toad in your hand? Aside from the small puddle of urine, you’ll also notice the cool, clammy, thin skin. It’s like holding a small pouch of bones.

 

 

 

 

 

Do what you can to encourage toads to visit your backyard. Your children will thank you.

Better Late Than Later

I am in the midst of crafting an actual post about an actual creature in your neighborhood (which should be up soon…I mean it!). While you wait you can check out this journal: Jesus the Imagination. The inaugural issue was published late June/early July of this year.

In it, I have a piece called The Benthic and the Celestial, about the connections I’ve found between benthic macroinvertebrates and spiritual beings. Sure, it’s not for everybody, but you might enjoy the poetry and some of the other fine essays found in the pages of Jesus the Imagination.

Chuck That! It Ain’t February.

I’ve been procrastinating on an article for this site for at least three months. I was going to write a brief review of a couple of ecologically-minded books; I even wrote two drafts–but, I ramble and you don’t care. Either produce content or shut up, you’re thinking. So, here ya go.

Woodchuck, groundhog, land beaver, and yes, whistlepig are all common names for the largest member of the squirrel family. This rodent, which not only has a national day set aside for it (unlike the faux holidays like Amphibian Awareness Day or Walleye Days) also has a movie named for it’s day. p14569_p_v8_ah

For the record, “The Gopher” in Caddyshack, looks more like a groundhog than a gopher. Feel free to debate me. I don’t think the filmmakers consulted an ecologist.

 

 

The groundhog or woodchuck, I refer to them by both names depending on the stage of the lunar cycle or whether it’s a leap year or not, is known as Marmota monax, which if Google Translate is to be believed, means “Woodchuck chuck.” Which if you know that old saying, “How much wood could a woodchuck chuck…” seems awfully serendipitous to me or else the taxonomer had an ironic sense of humor.

As mentioned they are related to squirrels, in the sciuridae family, and are really just a large ground squirrel. They are found all over the eastern US as far south as northern Alabama and extend up into Canada further west than the US, but can even be found in Alaska. Woodch5

The name “Woodchuck” is probably a bastardization of the Algonquian wuchak.

What’s This Thing Look Like?

Woodchucks are stocky with short legs and a bushy tail. Both sexes are similar, though males are slightly larger. Their fur is brown with some white giving a grizzled appearance–but albino and black individuals can be occasionally spotted.

The forefeet have long, curved claws (“the better to dig holes with, my dear.). The teeth include chisel-like incisors. The eyes, ears, and nose are positioned on the head as to allow them to peer out of the safety of their burrow just over the edge.

From head to tail, on average they span 20-27 inches and usually don’t weigh over 14 pounds; males tend to stay in the 5-10 pound range.

These be tracks of the beast.

This Land Is My Land

Woodchucks construct burrows anywhere from 8-66 feet in length with multiple exits and chambers (including one dedicated to defecation). These burrows can be found on the edge of a forest, in fields, and hedgerows, and in people’s backyards. They prefer being near open land.

As should be obvious, they have adapted well to human activity, being found near cleared land, road projects, and agricultural enterprises.

They love your lawns and gardens, people!

Muskrat Groundhog Love

They breed in late February (after their holiday, of course) or March, first beginning when they approach two years of age. Usually solitary, reproduction is one of the few times they hang out together.

Two to five kits are born in April or May with only one litter per year. The kits remain with the mother for about two months. After which time they are told to get out and get a job.

Them’s Good Eatin’

Beans, corn, peas, carrots, cucumbers, and even flowers will be sampled from your garden by the whistlepig. Clover, grass, soybeans, and alfalfa in other areas. Like their cousins, the squirrels, they can climb trees to grab an apple, pear, or nuts. And while they are generally herbivores, sometimes in the spring, before much has greened up, they will chomp on protein in the form of snakes and insects.

As a rodent, the woodchuck’s incisors continually grow. Thus they need to gnaw on wood or nuts to simultaneously sharpen and file the teeth down.

"Mom told you to keep gnawing. Now look what happened."

Their diets are affected by seasonal availability, hence the need for hibernation.

Little Did They Know…

  • Elderly for a woodchuck is seven years of age. On average, in the wild they live three to six years.
  • They are active from spring to fall and begin hibernation in October where their body temperature drops from 99 degrees F to 40 and their heartbeat slows from 80 bpm to only 5.
  • Woodchucks can swim!
  • They can be found sunning themselves.
  • Most states list them as a game animal. I’ve eaten smoked woodchuck; it wasn’t bad.
  • Have you ever observed one walking? They waddle.
  • My first experience with hard cider was with Woodchuck. I used to love that stuff, now my palate has grown. It’s a bit like moving from Stroh’s or Miller to a microbrew. download (3)

 

 

 

 

You may find the woodchuck a pest as farmers, my father-in-law, and my neighbor do, but remember they are part of your neighborhood. If you can deter them from your plants, let them be a fuzzy neighbor to you.

A tidbit

I know I’ve been away from this blog for too long and I’m slowly working on some new content…but in the mean time I’ll post some things by others to keep the embers glowing.

Here’s some good news from the Good News Network about the kings of the lepidoptera.
