Our Spring Outdoor Classroom
has resumed at Cibolo Nature Center where I volunteer leading students on
nature hikes. My favorite approach is to
tell them a naturalist is just a detective that is looking for clues to discover
what animals have been there. As the
predominance of animals are nocturnal, and the others are not likely to make
themselves seen when some 60 noisy kids are traipsing through the woods, then
what we have left is to look for clues they left behind.
Now it seems to me that there
were far more clues left in the Northeast woods than you find in Texas. We would find endless “middens”, piles of
discarded pine cones the red squirrel had eaten, or plenty of tracks, especially
in snow or in damp sandy places that abounded on the Cape. Scat (scientific word for poop) was fairly
easy to come by too; twisted ropes typical of coyote and fox that showed the
presence of fur or bone, or cherry pits or beach plum pits if either were in
season.
Here in Texas, the ground is
too hard for tracks, and it seems perhaps the presence of dung beetles make
even scat, with the exception of the omnipresent deer scat, hard to come
by. Now my roof, that is another matter;
it is festooned with raccoon scat that needs to be periodically removed. Clearly they enjoy eating and pooping with a
view.
But the one exception, the
one animal that leaves an incredible amount of “sign” around is the Texas State
Small Mammal, the armadillo. Because
they tend to have, as a minimum, 4-5 den sites and a maximum of 15, burrows
are everywhere. At least they are at Cibolo, which has a blend of
habitats. Armadillos prefer forest areas
where they can snuffle their way through the leaf litter looking for their
favorite food, beetles, and along riparian ways where the digging is easy. We have a creek running through the property
and there, you find many of their dens dug into the sloping creek banks and, when
the creek is dry, in the creek bed itself.
On top of that, when they are
looking for their insectivore meal, they
put that little pointy nose of theirs
down on the ground, in the mulch or the leaf litter, and plow along until they
find something tasty. Then they dig a
very obvious hole with the dirt shooting through their back legs until they
find the proverbial “little bugger”. Consequently, even the youngest child can
become an expert armadillo detective in short order.
The best purchase I made this
year was a cute armadillo puppet that can mimic all these actions; plowing
through mulch, digging and shooting dirt up onto the kids that are crouched
around and it been a big hit so far! Plus there are so many cool facts to share
about armadillo’s that you never run out of things to say.
Here’s a sampling:
-They have been steadily
moving north from the Central America through the Southwest and have been found
as far north as Illinois.
However when it is colder
than 70, they start to shiver. That’s
because they are mostly covered with those leathery keratinous scales with fur
only found between them. They retreat to
their burrows when it is colder than that.
We must have a lot of shivering armadillos for they clearly are foraging
each night and our “winter” nights are far below 70.
-Because they cannot regulate
their temperature well they are host to many bacteria and virus and, as many
people know, they are a carrier for leprosy.
However no need to panic. It is not
easily transferred to people, 95% of us are immune to it and the way you MIGHT
get it is eating one, which indeed was done in the past but not on many people’s
menu today. And today, leprosy is easily
cured with antibiotics.
-They usually have 4
identical young in the spring, which are all from one egg that might have been
fertilized the summer before. They are
able to have delayed implementation so that the young are born the following
spring. And those pups will stay in the
den for the first three months or so. Look
for little mini armadillos in early summer.
-The bony scales called
“osteoderms” are soft on the newborns and take months to harden up making them
the tastiest ones for predators to go after.
However, having eradicated so many predators, it seems to be up to cars
to keep their numbers in check.
- They can hold their breath
for 6 minutes and can choose to cross a river by tiptoeing on the bottom hippo
style or inflating themselves and floating on the top!
So now, four things on my
bucket list are:
-Seeing an armadillo leap 3’
into the air when startled, then coming down at a sprint that can reach 30 mph.
-Finding armadillo scat. Due to the fact that they eat mostly insects
it must crumble apart quickly and there is a rumor they may bury it like a cat.
-Seeing one hopping on its
hind legs clutching a load of leaves to bring back to its burrow to make a soft
bed.
-I read that they also can
climb trees! Well, they have really long
claws but I can’t say I ever heard anyone say they saw one in the trees.
So, bless you armadillo’s;
you provide so many things for me to point out on my walks, you provide many
other animals with shelter on a rainy or cold night with your plethora of
unused burrows and you are just one improbably cute critter. Villa la Armadillo!
