Goin' With The Flow: Yosemite's Frazil Ice

One of the things we love about the natural world is its capacity to continually surprise us with "really cool" events like the little known springtime occurrence of "frazil ice." Check out this amazing short piece shared by Caliso friend Scott Scott (of Trail Discovery) showing Yosemite's incredible frazil ice creek flows that stop and start up again someplace else.


Thinking like a naturalist--while watching this video (or after) think about these tried and true interpreter prompts, and complete these thoughts in order:

US Researchers Replicate Complex Bird Songs With a Simple Rubber Device

Find out how this discovery could impact wildlife science. A recent BBC article we came across via tweeter @thepineproject discusses the somewhat accidental discovery of bird songs that can be replicated by rubber. According to the team of US researchers, they have developed a simple rubber device that replicates complex bird songs:
  • The song is produced by blowing air through the device, which mimics a bird's vocal tract.
  •  The findings appear to challenge the idea that birds had to learn complicated neurological controls in order to produce distinctive calls.
  • The team plans to share its data with biologists to see if it sheds new light on how birds produce complex songs.

To see the device and listen to vireo and finch songs replicated by the device, read more...

11 Ways To Love the Planet In 2011

1. Protect species from extinction: prevent habitat loss, create yard habitats, prevent the detrimental effects of introducing non-native, invasive species and pesticides into our natural environments. Here’s an example of the danger of habitat loss and butterfly migration in this article from Science Daily.

2. Spend more time outside. Connect with the land, the sea, and the sky using all of your senses. Let a summer monsoon soak you. Follow animal tracks in the snow. Go camping, go picnicking, read outside, star-gaze, explore nature with your toddler, go soak in a natural hot spring. The more time we connect with nature the more we will love and appreciate it, and the more we will work to protect its right to exist and thrive—so that we may do the same.

3. Start a family nature club. It’s easier and more rewarding than you might expect! Here’s a fantastic and free Family Nature Club toolkit from C&NN. A wonderful resource.

4. Protect the night sky from light pollution. Mankind has a long history with the stars and moon; navigation, cosmology, agricultural cycles and more. Not only does light pollution take away the beauty and knowledge gained of the stars, the Milky Way and deep sky objects for modern man, it wastes billions of dollars annually, consumes valuable natural resources, and pollutes our environment. Light pollution can seriously disrupt the natural rhythms and processes of plant and animals, threatening their survival. Here are 10 easy steps to help prevent light pollution.

5. Become involved in your community by participating in local environmental projects like neighborhood recycling, abandoned lot cleanups, community gardens and watershed restoration projects.

6. Follow blogs, or start your own, that share information about wildlife, natural areas, green living, green mommies, family nature activities, camping, creativity and nature, our oceans, spelunking—whatever you wish to learn more about. When it comes to nature, the list of possibilities are endless! Just type in a blog search of what you want to find.

7. Lend your professional services to a local environmental non-profit, pro bono. Or consider volunteering your time to teach youth about the environment, become a naturalist, man community booths, or lead outdoor art programs inspired by nature.

8. Be mindful of the connection between your daily choices and their effects on the environment. We can decide which plastics are more easily recyclable, or if we walk, or bicycle instead of driving to work. Show your love of the planet; know that every individual action or small deed adds up to a healthier environment.

9. Support your local nature centers, botanical parks, nature preserves and national parks. Visit often, buy annual passes. Fall in love with their beauty, wildlife, their restorative and inspiring affects on you.

10. Calculate and then reduce your carbon footprint at home and while traveling. Click here for the nature.org calculator.

11. Become an environmental steward to protect natural and cultural resources and nature areas for future generations. Get started by searching the internet “how to become an environmental steward (your state/city).”

This is just the tip of the (melting) iceberg regarding ways you can protect the planet. For 25 more ideas, read this short article listing, “25 Ways To Give Back: From Fur To Feathers.”  The point is to get creative, and define what YOU value in the environment, then find ways to protect that gift from nature. Do you enjoy sitting on the porch at night and gazing up at the stars? Did an animal encounter speak to your soul? Do you yearn for camping under giant pines during the work week? Does the ocean move you to poetry?

Honor your nature connection.

5 Family Activities To Try This Holiday Season

As the holidays near, we are blessed with a little extra time for family…at least that’s the idea! One way to take advantage of these extra days is to include the whole family as you gear up for the holidays with special, nature-inspired table settings, foods, and decorating. Celebrate family togetherness by encouraging older children to guide the younger ones through easy and fun creations, either in the kitchen or the craft table, or outdoors.

No need to think extravagantly or big, it’s the simplest activities that work best, requiring the least guidance for maximum creativity. Here are 5 ideas to try:

Feather treasures. Plant colorful turkey/goose feathers (found at just about any craft store) throughout your yard for a fun treasure hunt for the little ones. Extra points if they find REAL bird feathers…those are magical :) Have them lay them around the center of the table, or in a vase for a whimsical addition to your table that they’ll be so proud to have contributed to.

Garden varieties. What better way to encourage your children and other family members to make those holiday get togethers extra special than by harvesting and sharing delicious edibles and flowers straight from their own gardens? Start new traditions, who will have the tastiest or most creative garden contribution?

Garlands, garlands, garlands! I don’t know about you, but we have a steadily growing pile of activity papers, duplicate worksheets and piles of drawing paper from our four year old. He also loves using scissors and ends up cutting up many of his creations (unless I’m able to rescue my favorites first!). So I’ve seriously considered creating a festive chain garland from these treasures.

Keep the papers and drawings you want, but if you can (I know it’s hard to choose!), turn the other paper piles from your child’s school into fun decoration. Assuming he/she will be okay with the two of you cutting them up! My little one also loves collecting leaves, incorporating them into this activity would be a great Thanksgiving accent. Paper chains are easy and you can create long ones in a very short time, your little one will love seeing these hang throughout your home! Start with their room :)

Mark this one. We’ve found that when kids get the green light to draw or write on any surface other than paper, they go crazy for it! We’ve invited kids (and adults) to decorate and write messages on a variety of natural items like river rocks, tree cookies, smooth sticks, and large leaves. Washable markers ensure an easy soap and water clean-up from colorful fingers, faces and arms, and clothes just in case ;)

Nesting instincts. It’s tough work building a nest, especially without hands. Challenge family members of all ages (they can work in teams if they want) to create a nest that would hold a little bird family--yes, use your hands. Take a walk or search your yard for ideal nesting materials: leaves, twigs, moss, lichen, stringy natural finds. You can offer some man-made materials—after all birds utilize these too—like string, cotton, strips of material, pet fur. Who created the prettiest nest? The sturdiest? The softest?

Green Spiders

Certain spider venom is being investigated as an eco-friendly insecticide. Scientists are getting closer to field-testing insecticides that mimic the action of spider toxins. In synthetic or natural form it can, potentially, target crop destroying insects with little or no effect on non-target species (e.g. beneficial bees and insects, birds, humans, other mammals, etc.). Unlike some conventional insecticides, target insects may not become naturally resistant to this spider-venom cocktail as they do with current chemical insecticides, and the spider toxins used in the engineered virus would not end up in the food supply. Read the entire article here.

The Green Lynx Spider (Peucetia viridans) gets its name from the way Lynx spiders sometimes pounce on their prey in a catlike fashion. These spiders spend their time hunting for insects in bushes and low plants. They are fast runners, but can occasionally be seen lying in wait for prey beside flowers. They build no web for prey capture, but they do release a silk dragline as they hunt among leaves. Look for a large, conspicuous spider: bright green, cream, or tan body with yellow legs that have black spiny hairs. Body length: 5/8". Common in Southern California and beyond.

One million spiders make golden silk for rare cloth. Here you’ll find a fascinating article on a golden cloth that’s worth a lot of green. It took four years and more than 1 million female golden orb spiders, known for the rich golden color of their silk (see image), to create an 11-foot by 4-foot textile—the only large piece of cloth made from natural spider silk existing in the world today.

Creature “Spirits”

Confession time: I’m a huge fan of all shows that chase after evidence of ghosts, cryptozoological creatures (like Bigfoot), and UFOs. I can’t get enough Ghost Hunters and Destination Truth, and surprisingly—or not—I find the debunking just as intriguing and fascinating as the “hunting.” Yes, I believe in the occurrence of things we cannot explain, or things considered paranormal or otherworldly, because it’s exciting to me and perfectly sensible. But, I also lean toward 98% of those reported “things” being explained by natural events, scientifically, as a coping strategy, or even as some cultural phenomena.

I once experienced a thunderous banging of the metal air ducts in the attic. It was the most terrifying, inexplicable sound at the time. I swore there was something huge up there, what else could make such a deafening sound! The week prior, my cousin had described the same thing when she experienced an extremely loud banging above our ceiling while she was alone in our house. She thought maybe someone was on the roof jumping around and even bravely checked it out for us. Seeing no one around, she left the house to sit in her car until we came home that night. She told us later that just before the crazy pounding, she kept hearing a light knocking or tapping noise on a particular wall in the living room that she couldn’t explain.

The crazy banging never happened again, but the tapping kept on for about another week. Was this an awakened spirit suddenly wreaking havoc on our little home? No. A rat was the culprit. The thundering clamour was likely the little beast navigating our metal air ducts in the attic. He was found, “removed” and our house was professionally rat-proofed by an extermination service.

In fact, much of the reported rustling sounds, groans, screams, human whispers, and even ghostly human giggling one might hear can be explained by critters very much alive and well, going about their business in the natural world. Have you ever heard a frog’s mating call? Or wind pushing, even “howling” through a boulder strewn canyon or between buildings, or pipes? How about a screech owl’s cry or a rabbit’s distressing squeal?

Nuisance Wildlife Relocation Specialist, D. Crawford offers very normal wildlife explanations for some of the most eerie paranormal sounds that may go “bump in the night.” Crawford discusses the rustling noises frequently reported in hauntings, reminding us that those strange noises in our basements, or in our walls and attics can simply be animals taking refuge in our home:

“Rustling noises coming from the walls or chimney can be caused by any number of creatures: bats, rats, raccoons, chimney swifts, etc. Bats or birds rustling their wings in the chimney or inside a wall can sound frighteningly similar to human whispering; the noises made by a colony of bats jostling for space may even sound like the rustle of silk skirts. A metal chimney shaft can sometimes produce a megaphone effect, making the noise seem louder or more intense than you might suspect.”

Even urban and suburban residents can be regularly visited by wildlife like owls, bats, raccoons, rodents, rabbits, and plenty of bird species. With increased habitat fragmentation it’s possible that adaptable critters like these will naturally seek and follow habitat corridors to get from one natural area to another; possibly wandering into your yard & home attracted by neighborhood trees, a nearby park, a cemetery, or wildland area as Crawford suggests.

Locally we have desert wood rats (packrats), famous for collecting shiny things like keys, jewelry, watches, and bottle caps from unsuspecting campers. If you live near a patch of desert, they just might enjoy moving into your home as well. Packrats, raccoons, and crows are mentioned in Crawford’s article as critters that may like to move around and collect items from your house—the possible culprits of poltergiest activity. The more we learn about the curious habits of our native animals, the more we can avoid jumping to paranormal conclusions, like things vanishing or being moved about or knocked over. It could simply be a curious creature—not a mischevious spirit. A little investigating yourself could solve the mystery, one way or the other.

For questions to help you determine if you are being “haunted” by wildlife, or to find out how Crawford debunked the ghostly screaming coming from a neighborhood graveyard, or to read about the poltergiest that was actually a sneaky raccoon, read his article found at the Paranormal Task Force website. Then listen to some of these eerily human-like calls and cries from common wildlife (creepy factor = high!):  

Fox call (often mistaken for human scream/yell):

Fox cry/call (often mistaken for a woman or child screaming or yelling):

Rabbit distress (sounds amazingly like a crying infant). Warning, some may find this one upsetting as this is a rabbit screaming in distress:

Arizona Woodhouse’s Toads (Bufo woodhousei) singing (sounds like human-ish screams):

Common Barn Owl call (sounds like a woman screaming):

See, not so scary after all! Or is it? Mwah-ha-ha-ha-haaa!
