Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we have an episode about some birds and reptiles. Thanks to Audie, Katie, Eilee, Emily, Maryjane, and Dylan for their suggestions! If this episode showed up later than usual in the podcast feed, it’s because I’ve been having trouble with the website and couldn’t get it uploaded until it was fixed.

We’ll kick off the episode with an animal that can’t kick, because snakes don’t have any legs. Audie suggested we learn about the scaleless rat snake, which means that first we have to learn about the rat snake, the ordinary one with scales.

Rat snakes are constrictors and are common throughout many parts of Asia, Europe, North America, and the Middle East, and they’re called rat snakes because they eat rats and other small animals like lizards, frogs, and baby birds.

Rat snakes are popular pets because they’re so pretty and they aren’t dangerous to humans. Different species are different colors and patterns, and the rhinoceros rat snake, also called the Vietnamese longnose snake, even has a little hornlike projection on the tip of its nose that points forward. I’m pretty sure we’ve talked about that particular rat snake before on the podcast, but I can’t look up which episode because the website is down.

Most rat snakes don’t grow much bigger than 5 feet long, or 1.5 meters, but a few species can get longer than that. The black rat snake, which lives in North America, can grow over 8 feet long, or more than 2.5 meters. It’s black with small white markings on the head, but snakes bred for sale as pets are sometimes white all over or partially white, or even albino, meaning an individual has a mutation where its body doesn’t produce pigment. Pet black rat snakes are also bred that don’t have scales.

That brings us to the scaleless rat snake. It’s an ordinary rat snake but it has a mutation that causes it to have very few scales. This is a mutation that happens occasionally in the wild since it’s a recessive trait, and while it can make the snake a little more vulnerable to injury, scaleless snakes can survive just fine in the wild. They do have belly scales like a normal snake, which are the ones that allow them to move around, and they may have a scattering of scales on other parts of the body too. A scaleless snake still sheds its skin once a year like an ordinary snake, since it’s actually the outer layer of skin that sheds along with the scales.

Scaleless rat snakes are popular as pets because they’re so soft and because their coloration is usually very bright. A snake’s coloration comes from pigments in its skin. A snake’s scales are actually transparent, so without a layer of scales, a scaleless snake looks even more colorful than a regular snake. Many species of snake have been found in the wild that are scaleless, but it seems to be a little more common in rat snakes.

Next, Dylan and Emily wanted to learn about the frill-neck lizard, which is found in northern Australia and the very southern part of New Guinea. It’s a big lizard that can grow almost three feet long, or 90 cm, including its incredibly long tail. Males are larger than females on average, with a bigger frill.

The frill is a flap of skin around the head and neck, and most of the time it’s folded back over the neck and shoulders so it’s not that noticeable. The lizard is pretty ordinary-looking that way, just a big gray or brown animal with a big head. But when the lizard feels threatened, or if it comes across another frill-neck lizard, it can extend the frill by moving the small bones and cartilage that act as struts, which also requires the lizard to open its mouth.

When extended, the frill is as much as a foot across, or 30 cm, and it’s marked with bright colors. Different individuals have different colored frills, red, orange, yellow, or white, or a mixture of colors and patterns. The size and color of the frill opening up so quickly will often startle a potential predator, allowing the lizard to escape. The frill-neck lizard can even run on two legs if it needs to, although it has to run with its head pointing straight up in the air.

The frill-neck lizard mostly eats insects, especially termites. It spends most of its time in trees and some people believe it can use its frill as a parachute, but that doesn’t actually seem to be the case.

Let’s move on to a few birds next. Maryjane suggested we learn about the bobolink, a type of blackbird native to the Americas. In summer the male bobolink is black with a pale yellow nape and white markings, and in winter he molts into a drab outfit of brown to help him hide. The female is brown with black streaks and stripes.

In the summer the bobolink flies to the northern United States and Canada to nest and raise babies, and it migrates to southern South America in winter. This is a huge distance for such a little songbird to travel, but it’s a strong flyer and can travel over a thousand miles, or 1,800 km, in a single day. It navigates using the stars at night and can sense the earth’s magnetic field too, which helps it find its way.

The bobolink prefers prairies and grassy areas. It eats seeds and insects, and especially likes rice and a type of caterpillar called the armyworm. It’s sometimes considered a pest because it eats so much rice, but then again armyworms are also considered pests and the bobolink eats so many of them that it has probably saved a lot of crops that way. While the bobolink is still numerous, its numbers have been in decline for years due to habitat loss.

The bobolink is most famous for its song. Both males and females sing, and males not only sing while perched, they sing while flying. The bobolink’s songs are varied and lovely. This is what the bobolink sounds like, first a song recorded while the bird was flying:

And here’s another song recorded while a different bird in a different place was perched and singing:

Finally, both Katie and Eilee wanted to learn about the great-eared nightjar, also called the dragon bird or the baby dragon.

Nightjars are nocturnal birds, and the great-eared nightjar is found in parts of southern and Southeast Asia. It can grow up to 16 inches long, or 41 cm, and is a chonky bird with big dark eyes and a broad bill that can open very wide. The “ears” in its name are tufts of feathers on the top of its head that look like ears or little horns. It can raise the ears if it wants to, but most of the time they just stick out backwards. Like other nightjars, the great-eared nightjar’s head looks flattened most of the time, and the bird itself spends a lot of time crouched down looking like a very flat bird, but then it sits up and pricks up its ear tufts, and it looks more like a thin owl with a long tail. The bird is brown with black markings, which makes it almost invisible at night.

During the day, the great-eared nightjar sits in a tree or just on the forest floor, so well camouflaged by its feathers that it blends in with the leaf litter or kind of looks like a piece of stump or broken-off branch. At night it flies around catching insects on the wing like a bat.

Instead of building a nest and laying eggs in it like other birds, the great-eared nightjar just lays a single egg among dead leaves on the ground. The egg, and the baby when it hatches, are so well camouflaged that it’s as safe on the ground as it would be in a nest way up in a tree.

The great-eared nightjar has an eerie call. This is what it sounds like:

Episode 424 Old-Timey Giant Snakes

Show transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

Recently I read about a giant snake supposedly seen in Tennessee in 1908. The story seemed a little suspicious so I dug into it, and it got a lot more complicated than I expected.

On July 25, 1908, the St. Louis (Missouri) Globe-Democrat ran an article about a giant snake in Loudon, Tennessee. Loudon is a town half an hour’s drive away from Knoxville in East Tennessee, although it took longer to get there from Knoxville in 1908. According to the article, the snake was “at least twenty-five feet in length, eight inches in diameter and twenty-four inches in circumference.”

The longest snake ever reliably measured is a reticulated python named Medusa, who was measured as 25 feet 2 inches long in 2011, or 7.67 meters. Medusa holds the world record for the longest snake in captivity. Reticulated pythons are constrictors, which are non-venomous snakes who kill their prey by squeezing them until blood flow is shut off to the organs, causing cardiac arrest and death. As a result, they’re incredibly strong snakes. The reticulated python is native to southern Asia and not likely to be found running loose in East Tennessee even today, and certainly not in 1908.

The famous Boa constrictor and other snakes in the genus Boa are all native to Central and South America, while the closely related anaconda is from tropical South America. These snakes are also constrictors.

The anaconda is rumored to grow over 30 feet long, or 9 meters, although the longest specimen ever reliably measured was 17 feet long, or 5.2 meters. Since snake skin is stretchy, though, preserved skins of huge size are often provided as proof of snakes much longer than the known maximum. While the anaconda isn’t as long as the reticulated python, it’s much bulkier, so a 25-foot anaconda would be much heavier and larger around than a 25-foot reticulated python.

The 1908 article claims that the snake “has been seen off and on for the last twenty-eight years, but not until this summer has it caused any serious alarm.” I don’t know about you, but even as someone who likes animals and thinks snakes are neat, if I saw a 25-foot snake I would be a little bit alarmed even if it wasn’t doing anything. The article then describes how the snake had knocked down a fence while climbing over it and that it had taken a lamb. One man even managed to shoot the snake, although only with “small shot,” and the article claims that the snake, “in a frenzy from the pain, tore up saplings in getting away.”

The article finishes by reporting that women and children were barricaded in their homes while men organized a posse to hunt down the giant snake, which was rumored to live in a cave overlooking the river.

The same article ran in various newspapers around the country for months, but there was no follow-up to let readers know if the snake had been found. But the story didn’t appear in any Tennessee newspapers.

The only 1908 article about a giant snake in Tennessee that appears in a Tennessee newspaper is from August 21. The Chattanooga, Tennessee Daily Times reported that a blacksnake “fully six feet long and two inches in diameter” had been spotted eating young pigeons above the Birmingham railway station. A police officer shot and killed it, but its body couldn’t be recovered from the steep hillside above the tunnel.

“Blacksnake” is a term used for two snakes that are common throughout the southern United States: the eastern black kingsnake and the North American racer. Both are black in color and can grow more than 6 feet long, or 1.8 meters. Both are non-venomous and eat small animals like mice, frogs, and lizards, while the kingsnake also sometimes eats other snakes.

The longest snake found in Tennessee, which also lives throughout much of eastern North America, is the gray ratsnake, which is frequently 6 feet long and sometimes longer. One unverified report of a captive snake 8 feet 10 inches long, or almost 2.5 meters, comes from Tennessee. It’s a mixture of dark and light gray with a lighter belly. It’s non-venomous and is actually a constrictor, although it’s not dangerous to humans. If it feels threatened, it will sometimes pretend to strike and rattle the tip of its tail against dead leaves or whatever else might be underneath it, which produces a buzzing sound that mimics a rattlesnake’s rattle. You’re not fooling anyone, gray ratsnake.

The eastern racer will also vibrate its tail against leaves to imitate a rattlesnake’s rattle, but the eastern racer is such a fast-moving snake that it doesn’t usually need to convince potential predators it’s dangerous. It just runs away. Despite its name of Coluber constrictor, it’s not actually a constrictor, although it will pin an animal to the ground with its body until it can swallow it whole. It and the gray ratsnake can both climb trees and will eat bird eggs and young birds when they find them.

There is another article about a giant snake in a Tennessee newspaper from 1908. The Chattanooga Star reported on August 20 that a 12-foot, or 3.6 meter, rattlesnake was attacked by a boar when it tried to enter a hog pen. The farmer managed to shoot the snake, which had 29 rattles. The snake was referred to as “Big Jim” in the area. But that story was supposed to have happened in Sullivan, Indiana, not in Tennessee.

But Indiana newspapers don’t run this account. A July 22, 1908 article in the Indianapolis News reports that a rattlesnake with 26 rattles was killed in Nashville, Indiana, but that snake was not quite six feet long, or 1.8 meters.

The “Big Jim” account does appear in one Indiana newspaper, the Hamilton County Times from August 21, 1908. But that article is headlined “Some Hoosier ‘Nature Fakes’” and says Big Jim was first spotted in the neighboring state of Illinois but had been discovered attacking a farmer’s chickens in Sullivan County, Indiana. This must be the same as Sullivan, Indiana reported in the Tennessee paper. But Big Jim was only ten feet long in the Indiana story, or 3 meters, and wasn’t killed. The article says the local farmers were organizing to hunt it down, but then goes on to talk about some other stories of huge snakes and a giant fish. It seems clear that the Indiana article is meant to be amusing, not factual.

The largest rattlesnake species is the eastern diamondback rattler, and the largest one ever reliably measured was 7.8 feet long, or 2.4 meters. That’s big, but it’s not Big Jim big. The eastern diamondback also doesn’t live anywhere near Indiana or Illinois. It’s native to the southeastern United States, especially along the coast.

Newspaper reporters weren’t always scrupulous in the olden days, sometimes making up stories to fill space and entertain the reader. Stories of huge snakes are so common in old newspaper reports that the term “snake story” was once used interchangeably with “fish story” to indicate an animal of improbable size that was supposedly spotted or killed, but without any proof.

In 1935, the Statesville (North Carolina) Record and Landmark ran an article titled “Giant Snake Story Proves To Be Hoax.” No kidding! In this case, though, the story was about a snake skin 16 feet long, or nearly 5 meters, which was supposed to be from a rattlesnake killed in a local swamp. The article revealed that the two men who claimed to have shot the rattlesnake had later confessed the skin was from a python, and had been sent to one of the men by a relative in South America. At least that one was from a real snake.
