Leap Day the Frog Way

Posted by in amphibians,Animal Origins & Fun Facts,Conservation,Uncategorized

The real purpose of leap day may be to keep the calendar aligned with the seasons, but here at the rescue project, we’d like to believe the day is designed to honor our favorite leapers. To celebrate, we’ve put together some fun facts about frog leaping.

Jumping Silverstoneia flotator

FUN FROG FACTS:

  • Not all frogs can leap, or even hop. The desert rain frog (Breviceps macrops) has legs that are too short to hop. Instead, it walks.
  • Male frogs of the genus Pipa are known to defend their territory by jumping at and then wrestling other males.
  • The New Guinea bush frog (Asterophrys turpicola) takes jump attacks one step further: before it jumps at a strange frog, it inflates itself and shows off its blue tongue.
  • Stumpffia tridactyla are normally slow-moving critters, but when they’re startled they can abruptly jump up to 8 inches. That doesn’t sound very far, but these little guys are less than half an inch long!
  • The Fuji tree frog (Platymantis vitiensis) may be the leaping stuntman of the frog world. Each time it leaps, it twists in the air—sometimes even 180 degrees—to throw predators off its trail.
  • The Larut torrent frog (Amolops larutensis) gets its name from a nifty leaping trick: it can jump into a fast-moving stream and back to its usual perch, the underside of a rock, without being affected by the current.
  • Similarly, the parachuting red-eyed leaf frog (Agalychnis saltator) gets its name because it speeds to mating opportunities by jumping from trees with finger-and toe-webbing spread wide.
  • The record for longest jump by an American bullfrog (Rana catesbeiana) recorded in a scientific paper is a little over 4 feet. But scientists who went to the Calaveras County Fair, which Mark Twain’s short story made famous for frog jumping, found that more than half the competitors bested that record—and one jumped more than 7 feet in one leap!
  • The Guinness Book of World Records doesn’t include any frogs for their leaping ability. But it does track human performance in frog jumping (jumping while holding one’s toes). There are records listed for the longest frog jump and the fastest frog jumping over 10 and 100 meters.

In honor of Leap Day celebration coordination efforts by Amphibian Ark, the Panama Amphibian Rescue and Conservation Project made this video for a frog song written by Alex Culbreth.

Elementary Students Help Houston Toads!

Posted by in Conservation,Endangered Species,Texas,What You Can Do

Two students from River Oaks Elementary School, Hunter Hensey and Chloe Hunter, were doing a project on endangered species (under the direction of the teacher May Hong) when they serendipitously came across an article about the endangered Houston toad in the Zoo’s December Member Magazine. The students learned from conservation staff at the Zoo that one of the main reasons for the toads decline is habitat loss. These two conservation champions got the supplies to make “seed balls” for landowners that live in the toads’ habitat. These seed balls protect fragile seeds from the elements and being eaten by birds until they can germinate.

You can make your own seedballs for native wild flowers and grasses by watching the following video at the Coastal Prairie Partnership website.

 

 

 

 

 

 

 

 

These native grasses provide habitat for a variety of insects which is what the toad needs to survive. Also, when hopping out of the pond, small and fragile baby toads also need grasses to hide in to stay safe from predators and to keep from drying out in the hot sun.

Hunter and Chloe came to the Zoo last Friday to drop off their seed balls and we will be delivering them to the landowners we work with in Austin County.

Please give a big thank you so these thoughtful students for helping their native and endangered wildlife! We are so proud of our young Zoo patrons and conservation ambassadors!

Hunter and Chloe- Conservation Champions!

 

Conservation in Madagascar

Posted by in Africa,Conservation,Endangered Species,Field Research,Travel

It is not uncommon to see the local people (Malagasy) in Madagascar creating eco-tourism opportunities using lemurs and other species.  They know where the lemurs are and they know foreigners like to see them!  The people do appreciate nature, but as populations grow and the need for food increases they seek any means possible to survive.  There is a great need for conservation that can provide sustainable solutions for Malagasy people in Madagascar.  

Our next speaker for our call of the Wild Speaker Series is Dr. Jonah Ratsimbazafy, who is a Malagasy primatologist and conservationist.   Early in his career he studied Archaeology and Paleontology in Madagascar, spending many hours digging up ancient lemur fossils.  He once told me he spent three days digging up a full skeleton of one of the giant extinct lemurs that were the size of humans.  This work brought him in and around villages where he saw people eating lemurs.  He told me one day he looked at the bones he was dusting off at the time, then at a small species of lemur being placed in a cooking pot over an open fire, and said to himself, “The lemurs in the ground can wait, but the lemurs in the trees need my help now!”.  That was when he decided to commit himself to conserving species in Madagascar.        
 

Come to the Zoo to hear about primatologist Dr. Jonah Ratsimbazafy’s work saving lemurs and other species in Madagascar on February 15th at 7:00 pm.    Be one of the first to hear all about his recent discovery of a brand-new lemur species!  Enjoy beverages and tasty appetizers from Houston’s own Beaver’s restaurant and meet some of the Houston Zoo’s animals from Madagascar up-close.  CLICK HERE to purchase tickets.

The joy of ring-tailed lemurs

Posted by in Africa,Conservation,Endangered Species,Field Research,Travel

Everyone seems to be familiar with ring-tailed lemurs these days, and they definitely hold a special place in my heart. Their wide spread popularity is not surprising when you consider how many children’s shows have included them as characters. My personal favorite is ring-tailed lemur, King Julian from the movie Madagascar.  He is definitely the most entertaining animated character of all time!

When I was a keeper, I often spent my free time observing our large group of ring-tailed lemurs. They have a relatively peaceful, but comical society. Often disagreements are settled with the females with babies clinging tightly to their backs at the front lines (that’s how risky the disagreements are). And, their most effective weapon is..…smell. Males arm up their tails with scent from glands on their wrists and fling it in the opponents’ general direction with great vigor. The whole event usually involves some dancing around each other until a smell wins out. It is all very entertaining.

I worked with a researcher that studied ring-tailed lemurs. She studied a group of lemurs living in caves in Madagascar. They actually looked quite different from the typical ring-tailed lemur. DNA work revealed they were in fact the same species but had evolved to have much puffier coats to keep them warm in their unique setting. During her studies with this group she also discovered the local Malagasy people in the area had created their own eco-tourism project using this group of cave dwelling lemurs. They charged to bring tourists to see these mysterious lemurs in the caves.

Dr. Jonah Ratsimbazafy is a Malagasy conservationist working to save lemurs and other species in Madagascar. Come and listen to his amazing stories on February 15th at 7:00 pm at the zoo. Be one of the first to hear all about his recent discovery of a brand-new lemur species!

Following lemurs in the wild

Posted by in Africa,Conservation,Endangered Species,Field Research,Travel

One of my zoo keeper friends was one of the fortunate few that got to join the researchers in Madagascar to assist in tracking the Carolina Five.  I treasure the stories she shared with me about following the group through the thick forest.  One of the lemurs, unfortunately, remained in a captive mind set at first and tended to prefer the ground.  It is very dangerous for this species of lemur to spend extended periods of time on the ground in the wild, so she described continuously pushing his fuzzy rump up the tree trunks until he started to recognize the yummy fruit he could find higher in the trees.

Her job was to watch the lemurs’ every move and her description of trying to keep her eye on these agile creatures high in the forest canopy travelling at brake neck speeds while struggling to navigate the forest floor riddled with trip vines was priceless.  When they rested in a tree she was instructed to document what they were doing, the angle of the tree branch, and collect any feces deposits.  This sounds a lot easier then it was. She was often quite a distance behind the lemurs and by the time she staggered huffing and puffing to the point of “rest” the lemurs would leap off on their merry way once again.

She said the front of her shirt would fill with bugs of all shapes, sizes and colors during her mad dashes to keep up with the lemurs and described trying to dump these out in mid run.  She often lost track of the group after a face plant or two and would then have to follow their calls to relocate them. 

Through it all it was, of course, a highlight of her life to document captive lemurs living in the wild.  This project was the first example of reintroduction I remember hearing about and was definitely one of the stories that inspired me to get into this wonderful career.

 

Dr. Jonah Ratsimbazafy worked with this project early in his career.  He actually earned his PhD from Stony Brook University in 2002 for his study of Black and White Ruffed Lemurs.  CLICK HERE to purchase your tickets to hear about Jonah’s work saving lemurs and other species in Madagascar on February 15th at 7:00 pm.    Be one of the first to hear all about his recent discovery of a brand-new lemur species!  Enjoy beverages and tasty appetizers from Houston’s own Beaver’s restaurant and meet some of the Houston Zoo’s animals from Madagascar up-close.

Introducing and Re-introducing Ruffed Lemurs

Posted by in Africa,Conservation,Endangered Species

Ruffed lemurs are definitely one of my favorite species of lemur!  They are terrible to clean up after, and horribly loud, but delightful characters.  When I was a zoo keeper, I worked closely with the oldest Red-ruffed lemur in captivity at the time.   I had to do some training with him once and the only reward he would consistently work for was his own reflection in a mirror.  The fact that he appeared to adore himself made him even more adorable to me! 

Ruffed lemurs came onto my radar in the mid 90’s after watching a documentary with John Cleese describing a re-introduction of captive ruffed lemurs back to Madagascar. The project was the first lemur reintroduction effort of its kind. Five animals were carefully selected for genetics and personality from Duke Primate Center in North Carolina, a world class lemur facility.  They kept the lemurs in very natural settings to encourage natural behavior.

They were nick-named the Carolina Five and were flown to Madagascar, then carried to a remote park.  All five of the lemurs were collared and released into the reserve with researchers following close behind. 

To be continued….

Lemurs Love Rafting

Posted by in Africa,Endangered Species,Field Research,Travel

I have always been fascinated by Madagascar.  Did you know that it is the world leader in primate diversity?   The story that many schools of thought support is that the earliest form of primate, the lemur, drifted over to Madagascar on a piece of land/rafty thingy.  It creates an interesting image in one’s head (or maybe just my head) – the ring-tailed lemur was definitely Gilligan, the skipper had to be an aya-aya, the millionaire was a sifaka…., but I digress.  Anyway, this primitive primate floated over to an island of paradise, an island with so much diversity there was no need to compete for resources.  Unlike the other early primates that dispersed to other lands and evolved to have larger brains enabling them to compete for food, the lemurs simply specialized. They evolved to accommodate their individual niches.  And as a result we now have over 97 different, fairly dim (relatively speaking of course), fabulous species of lemurs.

It is often hard to believe that species discoveries are still being made in this day and age, but new species keep miraculously revealing themselves in places like Madagascar.  Last month there was yet another exciting addition to the lemur family.  This month’s Call of the Wild speaker, Dr. Jonah Ratsimbazafy, a Malagasy primatologist, was one of the scientists to find it.  Come and be the first to hear about this brand new species on Feb. 15th at 7:00 pm at the Houston Zoo.  CLICK HERE to purchase your tickets.

It’s Groundhog Day!

Posted by in Animal Origins & Fun Facts

HOUSTON! We had no winter. This is clearly the fault of some burrow dwelling rodent, but most likely no the fault of the Groundhog but please feel free to debate that issue with friends and colleagues. Since you most likely need a little background to win the winter vs. rodent argument, I thought it would be a good idea to re-broadcast some Groundhogs Day (Feb. 2nd) information. Groundhogs by the way are favoring the Giants by 4 over the Patriots in Super Bowl 46. We know this because they came out of their burrows and noticed Tom Brady’s hair was all disheveled and groundhogs are very observant about these things and what it could mean.

Lets get something straight, “Groundhog” are not the Nostradamus of the rodent world. They can barely remember which drawer they left their pants in, let alone predict the changing of the seasons.

We do not hear much about this in Houston as we only have two seasons: Hot and humid or gonna be hot and humid soon, but folks in the North go nuts over this critter every February. According to folklore, if a groundhog emerging from its burrow on this day fails to see its shadow, it will leave the burrow, signifying that winter will soon end. If on the other hand, the groundhog sees its shadow, the groundhog will supposedly retreat into its burrow, and winter will continue for six more weeks.

Tradition has it that the early German settlers in Pennsylvania thought the groundhog to be a particularly sensitive and intelligent creature. They decided that if the sun shone on Candlemas Day then a wise animal such as the groundhog would see its own shadow and hurry back to its burrow for another six weeks of winter. The origins go back to ancient European weather lore where they relied on a badger or a bear to help them determine the change of the season. Actually Germans used a hedgehog to predict “a second winter”. Who wants to be standing out in a field when a Badger or a Bear wakes up for the season and is hungry?

This is not a Groundhog, Marmot or "Whistle Pig", but it is a whistling pig...

What is a Groundhog anyway? Also known as Woodchucks or Whistle Pigs, they are actually Marmots of which there are 14 species and at up to 13lbs, the largest member of the Squirrel family. Woodchucks are true hibernators, relying solely on body fat for winter survival. This begins at the first frost of the season and ends in early Spring. Is there a reason they wake up in early February other than to celebrate this tradition (envision groundhogs in party hats ringing in the new year…)? Emergence is determined by the outside daily temperature and an internal circannual clock which governs biological seasonality. Soon after leaving hibernation, sexually mature woodchucks begin the reproductive process. In essence, they are out looking to protect their territories from other males as well as find a mate. Humans manage to disrupt some of this by parading around their fields trying to figure out where a shadow is.

A few parting points here. On the news every year we see someone in Gobblers Knob, Pennsylvania with a Top Hat from the Groundhog’s Club Inner Circle (yes, this is for real) picking up Punxsutawney Phil to make his prediction. Do not try this at home! I repeat, keep your hands out of hibernating mammal dens. Next – did you know one of the most critically endangered mammals in North America is a Marmot? The Vancouver Island Marmot to be exact – link over to their website for more information and to see one of the cutest rodents on the planet.
