Cute Gray Kits

Published by under Mammals

Gray fox kits, Allegheny County, June 2014 (image from Tana A's video)

Last month when I wrote about red fox kits in Calgary, Tana left a comment that she had gray fox kits in her suburban backyard north of Pittsburgh!  Her discovery is especially cool because gray foxes are said to be less tolerant of civilization than red ones.

Filming from her upstairs window, Tana captured the gray fox family on video on June 21.  The screenshot above shows only four but click on it to watch the entire 16 minutes and you’ll see seven!  Don’t forget to read her description below the video for the background story.

Meanwhile here are some cool facts about gray foxes:

  • Unlike the red fox, which was imported around 1750 for the fox hunt sport, the gray fox is an expert at climbing trees.  It easily shinnies up trees and nimbly jumps from branch to branch.
  • Gray foxes eat the same foods as red foxes but make their home in deciduous forests with rocky, brushy terrain while the red fox prefers old fields and rolling farmland.
  • Gray foxes are monogamous and pair for life.  Both parents raise the family of 4-6 kits during the spring and summer.  (Seven is a big litter!)
  • The family group stays together until the juveniles disperse in late fall. The youngsters may later make their home as much as 52 miles away from their birthplace.
  • Predators of the gray fox include humans (people hunt them), great horned owls, domestic dogs and sometimes coyotes. Unfortunately vehicles kill them, too.

Tana was lucky to see the kits.  Within days their parents taught them to conceal themselves as they move about.  She only gets an occasional glimpse at dusk or hears a parent make a warning bark.

What a privilege to see them.  So cute!

Cute Kits

Most baby animals are cute but fox kits could win the Cutest prize.

Last month in Alberta, Dan Arndt photographed three red fox kits playing and exploring while their mother supervised nearby.  They tussled like puppies and paused to look curiously at the human with the camera.

Soooo cute!

Stotting

Published by under Mammals

Springbok pronking (photo by Yathin_sk, Wikimedia Commons)

Last month I learned a new word that describes what this springbok is doing.

Stotting, also called pronking or pronging, is a stiff-legged trot punctuated every few paces by a high jump.

Here’s a quick look at a stotting gazelle in real time.

And here’s a longer look at springboks in slow motion from the BBC.

Cheetahs make the springbok run.  What makes them stott?  One theory is that they do it to show off.

It’s certainly a “Look at me!” moment when a springbok jumps 13 feet into the air with his back arched and legs dangling.  When a male jumps he opens the pocket of skin that runs from his back to his tail, as you can see in the photo above.  This flashes his patch of white hair and, according to Wikipedia, emits a sweaty odor.

Springbok and Thomson’s gazelles aren’t the only animals that stott.  North American mule deer and pronghorn do it and young sheep stott, too, as a form of play.

Who knew?!

Protective Mothers

Published by under Mammals

Elk cow and calf, Benezette (photo by Paul Staniszewski)

June is “baby” time in Pennsylvania’s woods with fledgling birds, tiny rabbits, young groundhogs and cute fawns.

As I mentioned last week young animals found alone are not abandoned, they’re just waiting for mom.  You shouldn’t “rescue” fawns and if you’re lucky enough to see an elk calf in Pennsylvania, don’t go near it!

Just like white-tailed deer, elk mothers tell their calves to “Stay!” while they go off to feed.  White-tailed deer are afraid of humans and don’t raise a fuss about their fawns but elk cows are big and powerful.  If you approach an elk calf, its mother may attack.

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.  When she charges, you’re the one who’ll need to be rescued!

Paul Staniszewski is quite familiar with the elk herd near Benezette, PA and explains: “Although the elk are used to seeing people, they are still very much wild and will become unpredictable and aggressive when it comes to protecting their young.  If a protective female elk is endangering people in a public area, move away and call the PA Game Commission. They will temporarily close the area until the mother moves on with her calf.”

Just like humans, wildlife mothers do what they can to protect their young.  Hawks and peregrines swoop at humans, mother skunks spray, black bears and elk charge.  Yes, a sudden attack by a wild animal is frightening.  It’s meant to be!  You’re at the hands of an outraged mother and she wants you to leave.

When you’re outdoors be aware of your surroundings and watch for wildlife.  Remember that mothers are protective.  It’s all part of being a mom.

Don’t “Rescue” Me

Published by under Mammals

Fawn at Allegheny Cemetery, May 2014 (photo by Sharon Leadbitter)

This month you might find a fawn resting alone in the woods. He wants you to know: “Don’t kidnap me! My mother is nearby. I’m not abandoned!”

This fawn is resting in a place that looks like a field of square, granite boulders. Sharon Leadbitter found him as she drove through Allegheny Cemetery in Pittsburgh’s Lawrenceville neighborhood in late May. He was hiding by a headstone near the road.

Sharon often looks for wildlife in the cemetery where she’s seen groundhogs, foxes, deer, and many kinds of birds. When she pulled to the side of the road on May 28 she was surprised to find a fawn curled up close by. Sharon wrote, “So tiny!! Can’t be more than 2-3 days old. The hooves are still shiny. I was within 3 feet of it.”

The fawn is doing what comes naturally, resting during the day while his mother feeds elsewhere. He’s still too young to keep up with her so she told him to “Stay!” and left him alone so her presence won’t attract a predator to his location.

Six days later Sharon found a second fawn under the cemetery trees and this same fawn near another headstone. He has stayed here for many days because his mother knows it’s such a safe location. He’s bigger … and so are his ears!

If you find a fawn resting alone, don’t touch! Leave him alone! His mother has not abandoned him. She knows where he is (she’s a Mom!) and will come back when the humans are gone. She’s relying on her baby to stay motionless during the day. The worst thing that could happen is if a human “rescues” him and takes him away from his mother and her milk.  She will search for him when he’s gone.

The Animal Rescue League Wildlife Center in Verona, PA receives many calls about “abandoned” fawns at this time of year. Click here for their helpful fact sheet.  The Wildlife Center of Virginia urges us:  Don’t Be a Fawn Kidnapper!

Meanwhile, if you drive through Allegheny Cemetery move very slowly and be alert for wildlife. Perhaps you’ll see a fawn.

Don’t Look Now But…

There’s a cheetah on your hood and he has really big teeth.

Maybe he was too close for their lenses.  ;)

 

Thanks to Cris Hamilton for sharing her trip to Africa in February.

Raccoon Makes A Mistake

Published by under Birds of Prey,Mammals

 

Late Wednesday night, February 26, at 11:15pm a raccoon climbed the bald eagles’ nesting tree at Hays while a noisy train rumbled by in the valley.  Mother Eagle was asleep but she heard the raccoon’s rustle and stood up to defend her three eggs.  As the mammal crested the nest edge she opened her wings and took a few steps toward it.  The raccoon turned and fled.

When you watch the encounter on this archived video from PixController you can see everything that’s going on, but the participants can’t.  The nest is lit at night by an infrared lamp mounted near the distant camera.  The camera can “see” the infrared light but we, the eagle, and the raccoon cannot.  On that overcast night the animals were dark shapes to each other.  I’m sure the raccoon was frightened to find an eagle!

Raccoons raid songbird nests because the songbirds are powerless to stop them but they avoid raptors because birds of prey will kill them.  Why was this raccoon attracted to a bald eagles’ nest?

Scott Kinsey gave us the hint on PABIRDS yesterday morning when he wrote:

It has been fun watching the Bald Eagle nest cam from Pittsburgh.  Finally got to see a feeding.  I think it was the male brought a fish for the female at 10:39am.  She had it done by about 10:47 and back on the eggs. Might have been a Gizzard Shad around eleven inches?

As Scott points out, the female eagle eats at the nest and though she sets the scraps aside she doesn’t take out the garbage.  Lots of smelly fish scraps are up there on the sticks.   The raccoon probably smelled the leftovers and came exploring for a meal.  When he realized his mistake he was out of there!

This surely isn’t the first time a raccoon has explored an eagles’ nest at night.  We just happened to see it because of the night vision camera.  He was lucky he didn’t make a fatal error.

Click here to see what’s happening right now at the eagles’ nest.

p.s.  This episode points out another difference between bald eagles and peregrines.  Adult peregrines don’t eat at the nest during incubation and even when feeding nestlings they take out the garbage.

Prelude To A Fawn

Published by under Mammals

Here’s something you’re unlikely to see in Pennsylvania’s “Big Woods” north of Interstate 80 — a close-up view of a young 8-point buck taunting and sparring with an older one.

You’re unlikely to see this because Pennsylvania’s huge deer herd is quite out of balance up north.  Since doe hunting was suppressed more than 100 years ago the ratio of bucks to does has fallen steadily.  For example, on the first day of hunting season last month a friend saw a herd of 88 deer in Clarion County.  85 were does and the 3 bucks had only spikes for antlers.  To find out how this happened, read Bob Frye’s 2006 book Deer Wars: Science, Tradition, and the Battle over Managing Whitetails in Pennsylvania.

In no-hunt suburban areas, Pennsylvania’s deer proliferate with a good balance of males and females.  They’re used to seeing harmless humans, some of whom offer food, so they don’t mind coming close.

Sharon Leadbitter visits Allegheny Cemetery in the City of Pittsburgh to photograph the large herd.  Last summer she posted a video of a cute fawn frisking among the headstones. This month she filmed these two antlered bucks.

You can tell the young buck wants to spar as he jumps and dances. The older one persistently pushes him away and ultimately wins.

The winner will claim his favorite doe(s) and make more babies.

Their sparring is the prelude to a fawn.

Magic Eyes

Published by under Beyond Bounds,Mammals

When lights shine on an animal’s eyes at night, what color is reflected back at you?

For cats it’s green.  For possums it’s red.  For arctic reindeer it depends on the time of year!

The tapetum lucidum in reindeer’s eyes changes color to cope with the bright light of summer and low light of winter.  In summer their eyes reflect gold, in winter they look blue.

This cool effect was discovered by a team from University College London and University of Tromsø, Norway thanks to funding from BBSRC (Biotechnology and Biological Sciences Research Council).

Watch the video above and read more about the study here at Phys.org.

p.s. Reindeer have two other amazing traits: (1) They can see ultraviolet light and (2) They have no circadian rhythm.

Ready For Halloween

Published by under Books & Events,Mammals

Badger (photo from Wikimedia Commons)

The American badger is ready for Halloween.  He always wears a mask.

This nocturnal member of the weasel family isn’t found in Pennsylvania but occurs from western Ohio to the California coast.  He makes a living by digging for small burrowing animals, especially mice, squirrels and prairie dogs so his favorite places are grasslands where the soil is easy to dig and his prey is abundant.  That’s a habitat rarely found in Pennsylvania.

American badgers are nature’s backhoes but they work at night and are usually alone.  This makes them hard to watch and census.  Even so, we can guess they’ve declined or are missing from areas where prairie dogs have been eradicated.

For a 24 minute window on the badger’s life, watch this 1970 video from Mutual of Omaha’s Wild Kingdom which filmed them during the day.  I must say it brought back memories to see Marlin Perkins again.
