How many grasshoppers will a wolf eat?

According to a scat ana­lys­is, one wolf ate at least 181 grasshop­pers and prob­ably at one go.

That sounds like a lot of hop­pers but, giv­en that each one weighs ap­prox­im­ately half a gram, that means the wolf in­ges­ted less than a cup of in­sects. Definitely a light­weight snack for a large carnivore.

It all star­ted a couple of years ago when Brandon Barton and some bud­dies were hik­ing through Hells Canyon Wilderness, which spans the Idaho/​Oregon bor­der. They were study­ing elk eco­logy but then Barton spot­ted some­thing odd – wolf scat that ap­peared to be filled with grasshoppers.

The trail was covered with live hop­pers and the group knew wolves ate a vari­ety of prey. But poop plugged with in­sect body parts seemed be­yond the norm.

Despite the pu­trid smell, Barton, a com­munity eco­lo­gist at Mississipi State University, triple bagged the scat for fur­ther ex­am­in­a­tion in a lab. In the mean­time, the group set up a couple of mo­tion-sensor cameras.

Sure enough, the black and white film caught a lone wolf vis­it­ing the trail every night to chow down on hop­pers. Because the in­sects are slug­gish when tem­per­at­ures are cool, it was as easy as a hu­man reach­ing into a bag of popcorn.

The big take away from the hop­per-filled turd on the trail ? It’s an­oth­er ex­ample of how all creatures, plants and wa­ter­ways are not isol­ated ele­ments in an eco­sys­tem; at some level they all in­ter­act to cre­ate a whole.

Of books and bears – Harold Macy launches San Josef

The first time I hiked into San Josef Bay I was wor­ried about bears. Didn’t even see a track. The second time, I woke up one morn­ing and grog­gily wondered why Rick was mak­ing so much noise out­side the tent.

Turns out, Rick had gone to in­vest­ig­ate the sea stacks and a bear was wan­der­ing through camp. Luckily, all our food and toi­letries were safely stowed in an im­pro­vised bear-hang.

I’ve ex­plored San Josef two oth­er times via the prin­ted page. The first was at a week-long writ­ing work­shop at Strathcona Park Lodge. That’s where I met an­oth­er wanna be writer, Harold Macy.

One af­ter­noon, while Harold’s wife and two young sons went for a walk, I sat on the floor of their suite next to a stack of pa­per. Harold poun­ded away on an old IBM Selectric type­writer (com­puters were few and far between in 1986) as I read a draft of his work-in-progress.

I re­mem­ber the evoc­at­ive lan­guage and the strong sense of a wild, wet land­scape and the haunted, hope­ful char­ac­ters that in­hab­ited it. The ma­nu­script began with a man in an oil­skin coat row­ing. For thirty some years I pondered the U.S. civil war deserter’s fate once he reached the strug­gling Danish set­tle­ment on north­ern Vancouver Island in Canada.

This sum­mer I found out when Tidewater Press asked if I’d write a blurb for the back of San Josef. Harold’s story ig­nited memor­ies of my vis­its to the re­mote bay and of the writ­ing re­treat that launched my career.

But most of all, I was struck by the de­vel­op­ment of the plot and per­son­al­it­ies. Both had ma­tured like a boda­cious red wine. Within three pages, Harold cap­tures the soul of a man and the land­scape he finds him­self in.

San Josef is a deep and some­times dark nov­el where hope goes astray but is nev­er lost. The char­ac­ters are as com­plex as a spider’s web, the lan­guage po­et­ic and the en­vir­on­ment a tan­gible force.

Harold Macy is the au­thor of The Four Storey Forest, As Grow the Trees, So too the Heart. His short stor­ies have ap­peared in PRISM International, The Malahat Review , Orion and oth­er publications.

On Saturday, Oct. 26 Tidewater Press and Harold Macy will launch San Josef at the Courtenay and District Museum at 2 pm. in down­town Courtenay, BC.

Admission is free; stor­ies will be filled with Harold’s trade­mark hu­mour and the his­tory that in­spired this novel.

Takaya: Lone Wolf

In 2012, an ap­prox­im­ately two-year old wolf sud­denly ap­peared on Discovery Island, not far from the densely pop­u­lated mu­ni­cip­al­ity of Oak Bay on south­ern Vancouver Island, BC.

He’d prob­ably dis­persed from his birth pack on Vancouver Island and was look­ing for a mate and ter­rit­ory to call his own. But some­where along the way, he made a wrong turn and found him­self in an urb­an area. So, per­haps con­fused or spooked, he swam through chal­len­ging wa­ters to a small cluster of islands.

Wolves are highly so­cial an­im­als, so no one thought he’d stay. But, des­pite all odds, he has. For sev­en years he’s sur­vived – and thrived – in a loc­a­tion that has no oth­er wolves, no year-round source of wa­ter and no deer or oth­er un­gu­lates to hunt.

Cheryl Alexander has fol­lowed the jour­ney of the wolf she calls Takaya with her cam­era and heart for nearly sev­en years. The renowned wild­life pho­to­graph­er has watched him swim from is­land to is­land, seen him feed­ing on seals and listened to him howl to­wards the lights of Oak Bay.

On Friday, October 4, the story of this re­mark­able wolf and wo­man will air on CBC TV’s The Nature of Things. Takaya: Lone Wolf is an in­ter­na­tion­al co-pro­duc­tion, which will run on BBC, CBC and ARTE.

Cheryl was a won­der­ful re­source while I was re­search­ing Return of the Wolf and I can’t wait to see the doc­u­ment­ary fea­tur­ing her pho­to­graphs and in-depth know­ledge about this un­usu­al wolf.

Small but big difference between wolves and dogs

There are, of course, many dif­fer­ences between wolves and dogs. Some are cog­nit­ive, such as a wolf’s will­ing­ness to be trained, while oth­ers in­clude phys­ic­al traits such as the predator’s ex­traordin­ar­ily long legs and huge paws.

A lot of phys­ic­al char­ac­ter­ist­ics have been spe­cific­ally cul­tiv­ated in dogs to en­hance their ap­peal to hu­mans. For in­stance, many people are at­trac­ted to dogs with floppy ears and short muzzles so breed­ers have se­lect­ively en­cour­aged these traits. Wolves have these en­dear­ing fea­tures as pups but, as they ma­ture, their ears be­come erect and their snouts lengthen.

A re­cent study found an­oth­er small but sig­ni­fic­ant dif­fer­ence between wolves and some dogs – their eye­brow muscles.

Whether they own a dog or not, many people are fa­mil­i­ar with that sad sack stare some dogs seem to be able to sum­mon at will. This is the look guar­an­teed to tug firmly on the hu­man heartstrings. And to of­ten foster for­give­ness for any trans­gres­sions that may have occurred.

This im­plor­ing gaze is gen­er­ated by a dog’s abil­ity to move a prom­in­ent muscle that runs along the out­er edge of the eye up and inwards.

Dr. Juliane Kaminski, a psy­cho­lo­gist at the University of Portsmouth in England, dis­covered this while try­ing to un­der­stand why some dogs are ad­op­ted from an­im­al shel­ters soon­er than oth­ers. Apparently, it’s all in the eyes. Those who used their lev­at­or an­guli oculi me­dial­is muscle were first out the door to a new home.

Researchers then stud­ied the fa­cial mus­cu­lature of ca­da­vers of sev­er­al breeds of dogs, as well as those of wild grey wolves. They found a pro­nounced eye­brow muscle in all of the dogs but not the wolves.

This arc­tic beauty has a typ­ic­al wolfish gaze and no sign of sad sack eyes.

Unlike short snouts and floppy ears, the eye­brow muscle was not in­ten­tion­ally in­tro­duced by hu­mans but evolved nat­ur­ally over 20,000 years or more of the hu­man and dog relationship.

Kaminski, who has con­duc­ted sev­er­al stud­ies on the ways hu­mans and dogs com­mu­nic­ate, notes that eye­brows play an im­port­ant role in hu­man body lan­guage. And though it’s not known if dogs move their eye­brow muscle on pur­pose, the res­ult def­in­itely ap­pears to at­tract humans.
