    Screamers: Species
    Mar 12 2025
    Summary: There are three species of Screamers. Join Kiersten to meet each one of them in more detail. For my hearing impaired followers, a complete transcript of this podcast follows the show notes on Podbean Show Notes: Screamers: https://animaldiversity.org Encyclopedia of Life: https://eol.org Music written and performed by Katherine Camp Transcript (Piano music plays) Kiersten - This is Ten Things I Like About…a ten minute, ten episode podcast about unknown or misunderstood wildlife. (Piano music stops) Welcome to Ten Things I Like About… I’m Kiersten, your host, and this is a podcast about misunderstood or unknown creatures in nature. Some we’ll find right out side our doors and some are continents away but all are fascinating. This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. This is the second episode of Screamers. I hope you enjoyed the introductory episode about this unknown animal. The second thing I like about Screamers is that there are three species of this bird. Let’s take a closer look at each species. Last week, I quickly mentioned the three species of screamer and gave an all encompassing description of this group. Today we will look at each species similarities and differences a bit closer. Let’s start off with the Northern Screamer, Chauna chavaria. The Northern Screamer is 30 to 36 inches or 76 to 91 cm long. They have a stout body with a disproportionately small head. As I said in the first episode, they have little, tiny heads compared to their body. Sexes have the same coloration, so both males and females look alike. Adults have a gray crown that begins at the beak and ends just beneath the eye. Longer dark gray to black feathers stick out behind the head a bit like a short ponytail. White feathers spread from under the chin and sweep across the face just below the line of gray crown feather. The long, gangly neck is covered in shorter black feathers giving the appearance of a shaved neck. Fuller gray fathers cover the rest of the body from the base of the neck to the base of the legs. Bare, red skin covers the eye area from the beak to directly behind the eye. Adult beaks are gray and their legs are orange with hefty, turkey like feet that have slight webbing between the toes. Juveniles are duller in coloration. All three species of screamer have sharp spurs on their wings at the manus, which is the distal portion of their forelimb. The Northern Screamer is also known as the Black-necked Screamer. From the description I just provided, I can see why. The northern part of their name comes from there distribution in South America. This screamer is found across northern Columbia from the Atrato River and Magdalena River valleys east into the Lake Maracaibo area of Venezuela. They are most often found near water in habitats such as swamps, marshes, lagoons, riverbanks, and seasonally flooded river plains. They are a non-migratory species, so remain in the same area year round. Movement within that region is not uncommon in the search of food and searching for mates and appropriate territories by juveniles and non-breeding adults. The Northern Screamer eats leaves, stems, and roots of aquatic plants. They usually graze like geese and can sometimes be seen doing this is loose flocks. Northern Screamers are listed as Least Concern by the IUCN, International Union for Conservation of Nature. They were last assessed in February of 2023 with a stable population numbering 60,000-100,000 mature individuals. Species number two, I am covering the species in random order so no importance is placed on which I speak about first, second, or last, the Southern Screamer, Chauna torquata. The Southern Screamer is also 30 to 36 inches or 76 to 91 cm long. They have a stout body with a disproportionately small head. This will be the same for all three species. The coloration differs from the Northern Screamer in slight ways, but once you know what to look for it is quite obvious. The Southern Screamer has a gray face from the crown of the head to an inch below the chin. They have the crest feathers sticking out from the base of the skull just like the Northern Screamer. The coloration on the neck of the Southern Screamer begins with one stripe of white feathers below the gray face and a stripe of black below the white feathers, The white and black feathers ring the neck like a collar. Below the black stripe the rest of the body is covered in gray feathers. The beak is gray and bare, red skin covers a small area on the face from the beak to just behind the eye, similar to the Northern Screamer. Their legs are orange with hefty, turkey like feet with a small potion of webbing between the toes. And, of course, they have the sharp spurs on the manus. Southern Screamers are also found in South America but south of the Northern Screamer's range, which...

    Screamers
    Mar 5 2025
    Summary: What’s all that racket? Could it be a Screamer? Join Kiersten to find out. Show Notes: Screamers: https://animaldiversity.org Music written and performed by Katherine Camp For my hearing impaired followers, a complete transcript of this podcast follows the show notes on Podbean Transcript (Piano music plays) Kiersten - This is Ten Things I Like About…a ten minute, ten episode podcast about unknown or misunderstood wildlife. (Piano music stops) Kiersten - Welcome to Ten Things I Like About… This is a podcast about misunderstood or unknown creatures in nature. Some we’ll find right out side our doors and some are continents away but all are fascinating. My name is Kiersten and I have a Master’s Degree in Animal Behavior and did my thesis on the breeding behavior of the Tri-colored bat. I was a zookeeper for many years and have worked with all sorts of animals from Aba Aba fish to tigers to ravens to domesticated dogs and so many more in between. Many of those years were spent in education programs and the most important lesson I learned was that the more information someone has about a particular animal the less they fear them. The less they fear them the more they crave information about them and before you know it you’ve become an advocate for that misunderstood animal. This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. This is episode one of the new series on Screamers. The first thing I like about Screamers is that they are birds. Yes, that’s right screamers are birds. Screamers are not people who run around screaming, I mean technically yes, but that is a subject for a different podcast all together, not Ten Things I Like About… I can’t believe I have created over 100 episodes and this is the first time I‘ve talked about a bird. It is a great bird to start with, though. We’ll have lots of twists and turns with this little known but seriously interesting bird. First, we’ll start at the beginning. What is a screamer? We have established that it is a bird but there many, many birds out there so I’ll narrow it down for you. Here comes the taxonomy: (For those of you just joining this podcast, taxonomy is the method that scientists use to classify and differentiate between species of living organisms. It consists of various group names to help make sure we’re all taking about the same animal, plant, or invertebrate.) The taxonomy of screamers is a follows: Kingdom: Animalia ( they are animals) Phylum: Chordata Subphylum: Vertebrata (they have an internal skeleton) Class: Aves (birds) Order: Anseriformes (this order includes the screamers as well as ducks, geese, and swans) Family: Anhimidae Species: There are three species of screamer. The Horned Screamer, Anhima cornuta, the Southern Screamer, Chauna torquata, and the Northern Screamer, Chauna chavaria. All three species of screamers look similar. They are a large birds at 27 to 36 in or 71 to 92 cm, weighing about 3100 grams, with a wingspan of 5.5 feet or 1.7 meters. That is a decently big bird. They are classified with other waterfowl, ducks, geese, and swans, so you may be imagining a goose-like bird, but here is one of our first twists. Screamers look more like a turkey than a goose. They have a large body with a short neck and tiny head, especially compared to their body. They have a hooked beak, more like a bird of prey than a duck. Their legs are thick and stocky, and they have very little webbing between their toes. Doesn’t sound much like a duck at all! So why are ducks and screamers classified in the same order? Genetic testing and cladistics science shows them as close relatives to ducks, geese, and swans, so they share an order but are in separate families. Screamers are found in wetland areas of South America such as swamps, marshes, lagoons, and lakes, as well as open savannas and meadows, and in the floodplains of moist tropical forests. They are most often found around water and they can swim, but they do not spend as much time in the water as ducks and geese. Another strange twist with screamers is the long spurs they have on their wings. Yes, long spurs on their wings. There are two large, curved spurs attached to the elbow on each wing of the screamer. The larger one is at the joint and a smaller one is just beneath that. They look like terrible claws they use to rip open prey animals or fight off predators, but they tend to use them only during intraspecies dominance fights at breeding season. This segues us into twist number three, screamers are herbivores. They have short, hooked beaks like raptors and scary spurs on their wings like a predator, but they eat leaves, stems, flowers, and roots of aquatic vegetation. They may throw in a few seeds, insects, and arthropods, but no carnivorous hunting. This is not what you expect when you look at a ...

    Bats: Conservation

    Summary: Bat conservation is the subject of the final episode of the series on bats. Join Kiersten as she talks about what is going on to help bats.

Some we’ll find right out side our doors and some are continents away but all are fascinating. This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. Sadly, this is the last episode of bats. I’ve had a ton of fun writing and recording these episodes. One of my favorite things to talk about is bats and I absolutely love educating people about bats. The tenth thing I like about bats is the conservation plans that we have developed to help them survive everything the world throws at them. All bats around the world are under threat. Some are classified as endangered and most populations are in decline. But there are people out there, like myself and you, fabulous listeners, that are trying to make the future of bats bright. Some of the things bats are fighting against include habitat destruction. Forested habitats across the globe are being cut down for human use. Building houses, strip malls, converting forest to grazing land, and mining caves for minerals are all devastating threats to bat populations. Shifting temperatures is also something impacting bats. The timing of the emergence of insects with the timing of the emergence of insectivorous bats from hibernation needs to be spot on, but with the altered temperatures around the world, that timing has shifted. Insects are emerging earlier because of warming winters and the bats are missing the window. This can negatively impact bats that migrate long distances to return to nursery sites where they raise their pups. Even nectar eating bats are impacted by the warmer temperatures because plants are blooming earlier and earlier. Those that follow the blooming flowers are getting caught in end of winter freezes that they are not physiologically equipped to deal sometimes resulting in death. Disease is another threat to bats. Currently in the United States insectivorous cave dwelling bats are combating a disease called White-nose syndrome. This disease is caused by a fungus, Pseudogymnoascus destructans or Pd, that loves cool, damp places. Sound like a bat hibernaculum? Exactly. The spores of the fungus get on the face of hibernating bats and digs into the skin there. It blooms into a white fluffy structure, hence the name white-nose syndrome. The fungus itself does not kill the bats, but it irritates the bats rousing hem from sleep too often during their hibernation causing dehydration resulting in death. We now know that this fungus came from Europe on the shoes of some spelunkers. Equipment was not cleaned properly before entering a cave here in the United States, so the spores were spread. It first appeared in caves in New York State and has now spread across all of the Eastern US and is making its way across the Midwest. It can survive in any cave that stays cooler all year round. When this arrived in 2006 it hit three species the hardest, the Little Brown Bat, Northern Long-eared Bat, and Tri-colored Bat. Their populations declined 90%. This is one of the reasons I chose the topic of my Master’s thesis. There is very little we can do to help bats combat this disease, but there is some hope that they can survive this on their own. Bat populations in Britain and surrounding countries have been in decline for much longer than those in the United States. When White-nose syndrome was traced back to the spelunkers that had just returned from a European caving trip, scientists on both continents began to collaborate and share notes. In an effort to find a cure for W hite-nose syndrome, they discovered that the bats in England have antibodies in their system that targets Pd. The bats living in Europe today survived a ...
