Merely Funny

Published by under Mammals

Today, we’ll have some fun with this video starring meerkats.  But first, just one educational paragraph.

Meerkats are a small type of mongoose that live in the Kalahari Desert of southern Africa.  Their bodies are about a foot long, their tails even longer, and they weigh 1.6 pounds.  Meerkats live in social groups of 20-30 individuals most of whom are siblings, offspring of the alpha pair who make sure they’re the only ones in the troupe allowed to breed successfully.

Other than the serious business of foraging and competition, meerkats are pretty funny.  For instance, they fall asleep.

This video combines some of the funniest clips from four documentaries on meerkats with the Overture to Carmen by Georges Bizet.

Have a laugh.  Happy Friday.  :)

Rare Sight

Published by under Mammals

For many years Paul Staniszewski has photographed Pennsylvania’s elk herd near Benezette, Pennsylvania, often with beautiful and impressive results such as a photo of a bull nicknamed “Attitude.”

But he hadn’t been able to capture a good photograph of a newborn calf … until last month.

Paul sent me the picture above and wrote,  “Since I have been photographing elk, I was never able to get a decent shot of a new born elk calf.  There always seemed to be some problem: the calf was too skittish, the grass was too tall, the mother was being too protective, the light was not good, and etc… Well on this occasion [June 12], I finally was able to get what I consider to be a perfect photo of an elk calf that was born just hours before.”

As you can see, elk calves resemble white-tailed deer fawns.  What you can’t tell by the picture is the calf’s size.  Adult elk are 3-4 times larger than white-tailed deer and their babies are too.  Elk calves weigh 30 pounds at birth compared to newborn fawns at 4-10 pounds.

You might think a baby this large would be easy to see, especially since elk live in a herd, but the mothers go off alone to give birth and they are very protective of their young.

An elk cow doesn’t have antlers, but she’s not something you want to tangle with.  She weighs about 500 pounds, stands 4.5 feet tall at the shoulder and is 6.5 feet long from nose to rump.

She’ll charge at you if she thinks you’re a threat to her baby.

That’s why her newborn calf is a rare sight.


Thanks to Paul Staniszewski for sharing his photos. For more views of Pennsylvania’s elk and information on photographing them, see his website here.

Flag Waving Fawn

Published by under Books & Events,Mammals

Though this picture was taken around Memorial Day, the fawn looks as if he’s celebrating the Fourth of July.

This little guy and his mother are part of the large deer herd that lives at Allegheny Cemetery in the city’s Lawrenceville neighborhood.  In late May the Veterans’ section was all decked out in red, white and blue.  The deer didn’t seem to mind the waving flags.

Sharon Leadbitter took their pictures and as the deer left the area the fawn did a little flag waving of his own.  See how his tail is up in that first photo?

According to a 1991 study published in The American Naturalist, fawns wave their tails much more than adults.  Winston Paul Smith studied the reasons why white-tailed deer wave their tails and wrote, “Tail flagging was observed in all age and sex groups, even neonates within hours after birth. The tendency to tail flag was greatest among fawns. As fawns became older, tail flagging decreased so that by 7 mo of age they tail flagged at a rate similar to that of yearlings and adults.”

Watch the Fourth of July parades today and see if you don’t think this applies to small humans, too.  Everyone waves flags but the youngest wave them more.

Happy Fourth of July!

Baby Woodchucks!

Published by under Mammals,Schenley Park

I walked home through Schenley Park on Tuesday hoping to see a lot of birds after the rain.  As usual the birds were not very active in the evening but I found something so cute it made me laugh:  two baby woodchucks!

I call them woodchucks because the word “groundhog” doesn’t fit something so cute.  They were compact and furry, the size of large guinea pigs and very naive.

At first they were oblivious to my presence but when I paused to watch they froze.  I moved again and they retreated into their den but they were so anxious to come out and play that they didn’t wait long enough for me to leave.  I took their picture with my cellphone when they came out again.

Extremely cute!  But they’ll have to learn to avoid predators or they’ll become breakfast for the red-tail babies.

p.s.  I went back on Wednesday with a nicer camera but the woodchucks didn’t make an appearance.

On a recent walk in the park I paused to look and listen for birds.  Instead of birdsong I heard rough scrabbling above me.

As I turned to look, the scrabbling stopped.


A squirrel lost his grip and fell straight down out of the tree. He landed flat on his belly and lay there blinking.

A second squirrel peered down from above.

Blink. Blink.

Game over! Lucky for him I wasn’t a red-tailed hawk.

He picked himself up and slowly climbed the tree. Huff. Huff.

And they resumed the chase, leaping from branch to branch.

March Madness

Published by under Beyond Bounds,Mammals

I thought March Madness was all about basketball until I stumbled on a recent RSPB headline, The Gloves Are Off at RSPB Reserves:

“With spring approaching, the brown hares of the UK are starting to ‘box’, and we’re encouraging people to head to our nature reserves to see the opening bouts of these amazing seasonal matches.

Unlike the male parties of the well-publicised recent heavyweight fracas, the dramatic sight of hares ‘boxing’ is actually the females fighting off the unwanted attention of overly amorous males.

The males gather together vying for the female’s attention and if not impressed, she uses fisticuffs to fend them off.”

The article was accompanied by a photograph but that was tame compared to this video from Scotland.

He chases, she boxes, they tumble, the fur flies.  She’s really letting him have it!

Clearly he doesn’t get it that when she says no she means no!

Mad as a March hare, no doubt.

Time To Wake Up

Published by under Mammals

It’s Groundhog Day all over again.

Moments ago (at 7:25am EST) Punxsutawney Phil emerged from hibernation, looked for his shadow, saw it(!) and told us we’ll have six more weeks of winter.  Amazing… considering how warm it’s been.

Every year Phil’s predictions are preceded by a week of partying and fireworks, and accompanied by much fanfare and ceremony.  Thousands attend the celebrations in person and by webcam.  It’s a formal occasion for Phil’s Inner Circle who wear bowties, top hats, greatcoats and gloves.

The gloves are useful.  Yes, it can be cold — it was 8 degrees in 2004 — but there’s a second reason.

Sometimes Phil is grumpy when he wakes up and it’s better for all concerned that he nip a glove instead of a hand.

I’m with ya, Phil.  I’m grumpy, too, before my first cup of coffee.

(photo of Punxsutawney Phil from the Groundhog Day website.  Click on the image to visit Phil’s website and read all about him.)


p.s. No one had to wear gloves today.  Phil was not grumpy, but some folks in the crowd were quite grumpy about his prediction!

What’s That Smell?

Published by under Mammals

An unpleasant smell is coming from the crawl space under our kitchen sunroom.

I first noticed a hint of it on Wednesday evening but I couldn’t find the source though it seemed strongest in the basement.  Day after day the smell has increased until this morning it is noticeably putrid.  I think something died in there.  But what?

The only access to the crawl space is from inside our basement … unless you’re a mouse …  and that was the last known location of the mouse I couldn’t catch last month.  I thought he was in the heating duct but no, he was probably walking on the heating duct while collecting that pile of pink insulation you see in center of the photo.  That pile is new and unreachable by humans. No wonder he never found the trap I set upstairs.

When my mouse adventures began I put two snap traps in the crawl space but they went untouched for days.  I worried that my cat, Emmalina, would explore the crawl space so I removed the traps when I became convinced the mouse was inside the ductwork.

Since Thanksgiving I haven’t heard the mouse at all so I thought he was gone.  Dang!  I feel like I flunked Nature Observation.  I made up for my mistake this morning by again installing snap traps in case the mouse has friends.

So now the house smells bad when the furnace runs and my imagination is working overtime.  How long will it take for the smell to go away?  What if that smell is poop and not death?  What if the critter is still alive?  What if it’s a rat?

I have a feeling I’m going to buy way too much anti-rodent gear today.

p.s. That brown spot in front of the insulation is a rock, not a mouse.

Just a Mild Fascination

Published by under Mammals,Plants

Jonathan Nadle is fascinated by porcelain berry.  He wondered if his cat would be too.

I think it’s safe to say the cat did not catch Jonathan’s enthusiasm. 

Click on the photo of Larry Cat to see the very mild reaction of one imported species (Felis catus) examining another (Ampelopsis brevipedunculata).

The Observer Effect

Published by under Mammals

There’s a principle in physics called the observer effect that states the observer cannot help but affect the outcome of the experiment. 

I think this applies to mice.

After your advice last week I put a peanut-butter-laden snap trap inside the ductwork at the only spot that’s flat.  Though it was rather far from the mouse’s last known location, he should have smelled it.  It was upwind.  Two days passed.  No mouse.

Saturday morning I was contemplating a change to my bait strategy when Emmalina took a deep interest in the kitchen heat vent again.  I lifted the vent cover and the unseen mouse immediately scrabbled deeper into the ductwork.  Aha!   He was near the top.

I wanted to use a snap trap but there’s no way to keep a healthy cat out of the kitchen.  The entry has no door to close and there’s a window pass-through to the dining room. 

So I erected an elaborate contraption which wouldn’t have been necessary if I didn’t have a cat.  I took off the vent cover, put a snap trap near the opening and covered all of it with a cardboard box.  I taped the box to the floor, not because I feared the mouse would escape, but because I knew Emmalina would overturn the box if I didn’t nail it down. 

We waited.

Sunday morning Emmalina was sleeping on my lap when we heard the mouse climbing up the vent.  I froze to wait.  She jumped into action.

The mouse kept making noise until Emmy danced on top of the box and tried to dig everything away from the wall.  He scrabbled back into the vent and now, 24 hours later, we have not heard him since. 

This morning I again peeled the blue painter’s tape from the box seam and checked inside.  Nothing.

Am I too impatient or is it time for a new strategy that’s less prone to error?

I don’t know how to compensate for the observer effect.
