This week’s wolf logs are based on observations by our Biology 1476: Wolf Ethology participants

Melonie and Suzanne – The weather this week was unusually hot and humid for the Ely area, resulting in more resting behavior from the wolves. However, it was cooler on Wednesday. The wolves became anxious from the wind. Throughout the week, Boltz was ever-watchful of Luna, the wind overhead, and the flies. When not distracted by these elements, Boltz explored the enclosure and interacted with the other wolves comfortably. He spends a considerable amount of time resting on the sand pile, more than any other wolf. When not on the sand, he often moves into the shade where there is a shallow bowl. Even when resting in these areas, Boltz most often has his head raised, ears rotating, or one eye open.

We’re still working with some anxious behavior from Boltz due to his phobia of bees. Insect season has really come into full swing, and the sound of buzzing around him can make Boltz very intimidated. Recently he has spent most of his time in a dug den in the back of the enclosure. All of the sand and dirt can serve as protection for him from the bees and flies. He does spend time in the open seeking social company however, today he came down when a storm rolled in to rest beside Denali under the eaves in front of our observation area. Though the winds and thunder were relatively intense, visitors were given an excellent view of the pair through the storm.

I have said this many times, Boltz has some shyness that we will never overcome because he was nearly a month old when we met him.  But, the shyness is not just a socialization issue.  Boltz seems to also have an issue with bees.  He was stung when he was younger and that negative event has made him obsessed with the noise of buzzing flies, bees, hornets (unfortunately, we have a lot of the aforementioned). This makes it even harder to work with him because he is so panicked by the summer bugs.  You will notice he is less groomed than the other wolves, anything coming over his head makes him a bit nervous.  So instead of brushing, we pluck his hair.  We are working on his trust, but at this time, the only thing that works is if Boltz has Denali at his side.  These two wolves have a very strong bond.  We won’t give up, he may well be the future pack leader, so we want to increase our bond and his confidence.   He does have his favorite staff, so we know there’s hope. 

The summer season is the time for wolves to transition into a more nocturnal existence.  Boltz was awaken during the middle of the day to have a photo taken.  After displaying a fore-stretch and extending his front legs as far as he could reach, he trotted back up the hill to retreat in the cooler forested environment.  Such is the life of a summer exhibit.  We started the noon enclosure enrichment programs, which we conduct in the summer to help cool the wolves, and give them some stimuli that motivates them to come into view.  Today’s enrichment was beaver tails, and Boltz’s wasn’t nearly as adept at locating via scent as the other wolves.  He seems to be a bit timid in most interactions, and the search for hidden food tends to create excitement and competition.  These are two things that Boltz would rather avoid.

Every wolf has a different personality and Boltz is no exception.  He certainly seems to be wary of the unknown and likes to engage in social behavior with those he does know.   He continues to be the wolf that works for his meals, but has recently been shown sharing a weekly carcass feeding with both Aidan and Denali.  It’s Luna that rarely shares her meal.  As part of a spring parasite protocol, we acquired recent weights.

Boltz is believed to be a Great Plains subspecies, and may never reach Aidan and Denali’s weights (both Northwestern subspecies), but his more timid behavior may also be keeping him from maximizing the carcass.  We do hand feed Boltz smaller quantities of food whenever we thing he isn’t getting his fair share.  His weights as an adult appear to fluctuate between 109 and 112 lbs, which is still a large size for a Great Plains subspecies.  It is best to compare him to Grizzer (another Great Plains subspecies) during the same time frame.  As a yearling, Grizzer was 93.5, Boltz was 102.5.  By the time Grizzer was three, he weighed 110 pounds, similar to Boltz.  But, what Boltz might have to look forward to is that when Grizzer met the next generation of Exhibit Pack members in 2009, he  must have been taking advantage of extra pup food because his weight between a three year old and a four year old increased from 110 pounds to 121 pounds. 

6/5/2013 Boltz 102.5 lb
8/14/2013 Boltz 109.56 lb
6/13/2014 Boltz 111.9 lbs
5/1/2015 Boltz 109.34 lbs

 

 

Boltz and Luna were both born in 2012, and even though they had an unusual separation because of Luna’s condition, they were pup mates.  Pup mates wrestle, scruff bite, growl, bite some more, snap, bite some more and drag each other around as they practice skills to be an opportunistic predator.  When one pupmate is the lone female and is expected to fulfill the rank of the dominant female, it’s hard for the other pupmate to transition to this change in relationship.  Will Luna every be anything more than a pup mate to wrestle with?  As they both mature, they both may grow out of the need for the pup to pup rough housing.  Although, there are times that Aidan and Denali still act like pup mates, so it could just be in their nature.  At this point, we just need to calm the rough housing a bit so it doesn’t create a stimuli for Boltz to test Aidan.  We’ve been seeing a little testing as he matured, but nothing that Aidan can’t handle.  One more winter and then the pups come.  Pups will be the change in focus that Aidan needs to give him some relief.  If Boltz wants to wrestle, the addition of two male pups in the fall of 2016 will give him the chance.

Boltz was three years old on March 17th, and in honor of his birthday, we attempted to provide him a significant treat in the form of a cow leg.  Unfortunately, Boltz’s lack of confidence in keeping the steer leg resulted in Luna spending most of the webinar enjoying it, with only a brief loss to Denali.  As the evening advanced, surveillance video captured Boltz enjoying the leg 4 hours after the webinar ended.  Boltz did manage to guard 3 beaver feet.  As the photo shows, his lip curl is sufficient to keep the other wolves at bay.

Meet Our Wolves - Boltz

 We still see a bit of the direct stares and tail postures from the testing phase Boltz went through, but there’s not much follow-up now. We’re still working on trust and confidence issues with Boltz, in this week’s youtube you can see Boltz approach wolf care staff, but not necessarily interact with them. He has his good days, and his weary days. As I write this, we’re experiencing some gusts of wind at the center, which makes for a nervous Boltz. He has calmed down for now, and is resting atop the slate den in the enclosure.

While much of the winter was spent testing the dominant male, Boltz’s testing seems to have calmed down a bit. We still see some following behaviors, direct eye stares, and high tails now and then, but the interactions do not appear to be as intense as in previous months. Younger animals will often test their older, aging counterparts for quite a while. In some instances this will continue until the older animal’s retirement here at the International Wolf Center, but in other cases, testing may be put to a halt by the dominant animal. It’s hard to say how Boltz’s story will go, only time will tell.

Boltz is showing an increase in predatory drive with ravens, but in this image, he was photographed stalking Luna.  I certainly see Boltz showing some tendency towards more dominance, but I also see him in social behavior with Denali at the bottom of the order.   We have another year of status before the pups arrive, our goal is to keep Aidan strong, let Boltz be comfortable with his position.  Wolves tend to be Neophobic or fearful of new things, but Boltz tends to take his intimidation to a higher level.  He’s calm when Aidan’s calm, and when there’s some intimidation, he tends to redirect.
