Our latest wild and wonderful Wildlife on Wheels (WOW) program focuses on the animals of the rainforest — from tree frogs and slithering snakes to millipedes and rainbow boas.
WOW presenters break down the layers of the rainforest — the forest floor, understorey, canopy and emergent layers — and impart the important role rainforests play in contributing to our natural resources.
For example: Did you know that more than half of the world’s plants, animals and insects reside in the rainforest? Its vitality is crucial to the world’s oxygen supply, and its rich plant life is the source of lots of modern medicines.
Using live animals and specimens, HMNS educators also teach students about the rainforest’s unique quirks. For example: Did you know that 50 percent of rainforest rainfall never even hits the ground?
HMNS Wildlife on Wheels programs can be booked as supplements to a field trip or delivered straight to your school for an in-class presentation.

When you want to see a degu, an African Burrowing frog or an echidna, where do you go? You’re probably thinking the Zoo, or maybe on the National Geographic channel.
So where do you go to touch a degu, an African Burrowing frog or an echidna? Would you believe . . . a natural science museum? Even better, would you believe the museum could bring these fascinating creatures to you?
The best way to understand the different vertebrates is to meet them!
HMNS has a plethora of outreach programs that do just that. One of our most popular (and my favorite) outreach programs is Wildlife on Wheels. The Vertebrates theme can bring the aformentioned live fuzzies, squishies and stuffed pokies to schools, scout meetings, church groups, festivals or anywhere a group wants to learn. I love seeing the looks on kids’ faces when we present slick amphibians like salamanders or show them the actual size of an emu’s wing.
One of the best parts is having kids (and the occasionally squeamish adult) touch our live animals. You can see the excitement, trepidation and — hopefully! —understanding on their faces as they interact with something they may have only seen in a movie.
A frog makes friends.
The Vertebrates theme brings an array of back-boned animals — both stuffed specimens and live creatures — up close and helps people make connections. Because the Vertebrates theme covers all five Vertebrates groups, it’s easy to illustrate the similarities and differences between fish, amphibians, reptiles, birds and mammals.
It is also, I think, our loudest theme — but what can you expect with live birds in tow and tons of inspired kiddos? Even our toads will sometimes get in on the “chorus” if you hold them just right!

It seems like a simple enough idea, but we can also adapt the program for different age groups. We love to talk about cool stuff, like what we call “the Rule-Breakers.” By “rule breakers,” I mean those animals that don’t seem to fit in our carefully constructed categories.
Think about egg-laying mammals like the echidna. What about snakes that have live birth? Consider the endangered sawfish, a family of rays that traverse both fresh and salt water. How about a fish with lungs? There are so many oddities and so little time.
I love our Vertebrates topic. You can simplify the program and use it as an introduction to back-boned animals, make it an energizing refresher, or even make the first scientific connections in a child’s mind.

Perhaps one of the most compelling segments of National Geographic Channel’s upcoming “Great Migrations” series is the first one, “Born to Move” (premieres Sunday, November 7 on NGC). In this segment the need to migrate (move) is ingrained in each featured animal as a means to survival. Featured species include Christmas Island’s red crab (Gecarcoidea natalis), the far-traveling sperm whale (Physeter catodon), and the monarch butterfly’s (Danaus plexippus) annual journey across North America to a single site in central Mexico. One of the more heartbreaking sagas involves a young wildebeest (Connochaetas taurinus) calf falling prey to Nile crocodiles (Crocodylus niloticus) as its mother watches on helplessly – nature can indeed be cruel, and unfortunately not every story of life terminates in a rainbow.
“Beastly River Battle”
A tragic and violent scene plays out as wildebeest herds attempt to cross a river teeming with crocs.
The footage brings to mind some components of the Frensley/Graham Hall of African Wildlife, which I helped build here at the Houston Museum of Natural Science. In the Okavango Delta diorama, where the theme is “water is life,” we have a plasma screen featuring natural history aspects of the Nile crocodile, some of which I filmed in Kenya’s Samburu River, including footage of the crocs using their group hunting strategy to predate a large impala (Aepyceros melampus) buck. There is also other footage of crocs predating adult Thompson’s gazelles (Gazella thomsonii) and wildebeest, which is not as painful to watch as the crocs seizing an innocent calf as the mother looks on.

on its way back to the rich green lands of the delta.
In other parts of the African Wildlife Hall we also feature the quintessential Serengeti migrating hoofed mammals, including plains zebra (Equus burchelli) and wildebeest. Zebras are grazers that may congregate in great numbers in favorable areas. The zebra’s pattern may serve two functions. Firstly, when a herd of zebras are observed by a predator the black and white pattern breaks up the outline of individual animals, making it more difficult to pick out a target. More recently, it has been discovered that the pattern plays a role in triggering and reinforcing herd behavior in the zebra. For any given Zebra, being in a herd provides more eyes and ears to detect approaching predators; once those predators strike, it is relatively unlikely for any one zebra that it will be the one to be caught. These advantages outweigh the disadvantage of having such non-camouflaged coloration. You can witness the zebra’s migration from Botswana’s lush Okavango Delta to the Kalahari Desert in “Race to Survive” (premieres Sunday, November 14).
The ‘clown of the Serengeti’ or wildebeest, follows the wax and wane of the grasses that sustain them. Their short-distance migration numbering in the hundreds of thousands is one of the great nature spectacles of our planet. Harried by predators and the necessity of seeking fresh grazing grounds, the wildebeest manage to mate and give birth while they travel. Eighty percent of the wildebeest calves (as many as 20,000) are born within several weeks at the start of the rainy seasons and, within minutes, are able to stand and run, traveling with the herd as they migrate. The vast numbers of newborn far exceed the predator’s kills. So even though it is heart-wrenching to watch the croc take the life of the wildebeest calf in “Born to Move,” several thousand will survive the journey. Wildebeest are a keystone species in their habitat, one that if removed, causes the collapse of the community, which revolves around it.
Overall, birds migrate much further than mammals. For example, wildebeest in East Africa are famous for their annual migration across the Serengeti, which is actually less than 500 miles. The Arctic Tern in contrast flies 22,000 miles each year on a route that takes it from the Arctic to Antarctic and back again. When I think of the title of the segment “Born to Move,” I think of many species of birds that are really capable of moving (migrating) very far distances. This very aspect is highlighted in the African Wildlife Hall’s Saharan Desert diorama where the theme is “perilous migrations”.
As you can imagine, migration has many challenges; the Saharan desert for example is the greatest single obstacle for birds that migrate back and forth between Europe and sub-Saharan Africa. Covering most of the northern third of the African continent, it takes a songbird 35 to 40 hours to fly across this vast desert. Many birds fly the desert at night to avoid the intense heat, but there are many other perils birds must face for which they have no solution in their behavioral bag of tricks: traps set by humans, exotic predators such as house cats in unnatural concentrations, tower and window obstructions, environmental extremes such as drought brought on by global climate change, and destroyed habitat every step of the way. Indeed, migratory birds in the Americas face many of the same perils.

The birds featured in the “perilous migrations” diorama take advantage of the Northern Hemisphere’s annual explosion of food resources, then head south into Africa as fall approaches. Such migrations offer the advantage of allowing a bird to remain in ‘food-friendly’ seasons. Whether crossing the Old World or the Americas, a fundamental challenge for migrants is maintaining energy reserves – if a bird runs out of fuel it will perish. As a result, habitat loss is the greatest threat worldwide for migrants. Not only must they have suitable habitat in both their nesting and wintering ranges, but along the path in between as well. During migration many species will stop to ‘refuel’ even in some of the most unlikely environments, such as the Saharan desert.
Featured in the Saharan desert diorama are two birds with contrasting migratory strategies: the lesser grey shrike (Lanius minor) and the grasshopper warbler (Locustella naevia). Like many other African birds, the shrike nests far to the north in Europe, necessitating a Sahara crossing during migration until it reaches its wintering grounds in southern Africa. Then it crosses once more for the return trip to Europe. The warbler migrates a shorter distance through the Saharan desert to stop in central (rather than southern) Africa each winter.
The Houston Museum of Natural Science was founded in 1909 – meaning that the curators of the Houston Museum of Natural Science have been collecting and preserving natural and cultural treasures for a hundred years now. For this yearlong series, our current curators have chosen one hundred exceptional objects from the Museum’s immense storehouse of specimens and artifacts—one for each year of our history. Check back here frequently to learn more about this diverse selection of behind-the-scenes curiosities—we will post the image and description of a new object every few days.
This description is fromDan, the museum’s curator of vertebrate zoology. He’s chosen a selection of objects that represent the most fascinating animals in the Museum’s collections, that we’ll be sharing here – andat 100.hmns.org- throughout the year.
