Silverback Inshuti Retreats to Mount Karisimbi

Midway through the spring rainy season, when all of the Karisoke-monitored gorilla groups move down to the bamboo zone along the Volcanoes National Park border, one renegade silverback consistently leads his group farther up to the cold, misty, highest reaches of the volcanoes. Why is it that Inshuti, year after year, chooses not to lead his group to the prolific bamboo shoots along the border? Though it’s only speculation at this point, perhaps it is because he is the only male in his group and thus has no “backup” in the event of an interaction with another group. This leaves him more vulnerable to lone silverbacks and other males looking to steal his females. Heading down to the bamboo zone during the shoot season, the gorilla groups are forced into close proximity with one another and it is a time when inter-group interactions are on the rise and anything can happen. In previous years, no outstanding event precipitated Inshuti’s retreat up to the higher elevations. This year, however, his decision to move up the slopes of Mount Karisimbi - an area where the research groups normally do not range - can be easily explained. The silverback has kept his group up on Mount Karisimbi ever since all the turmoil and drama that led to the loss of two of his females in January and February 2012. Inshuti was an injured, weakened silverback with no beta male. Considering all of the aggressions that he had endured in the previous months, it is not hard to understand his motive: move higher up in order to avoid lone silverbacks prowling for females and safely keep what is left of his former six-member group. Karisoke researcher Winnie Eckardt, PhD, trekked to Inshuti’s group on Thursday, April 26th, aware that they were ranging at least four hours from the park border. With three Inshuti trackers, Phocas Nkunzingoma, Simon Havugimana and Gustave Busheja, the team climbed up Mount Karisimbi’s slopes to almost 3,800 meters (12,467 ft.). Spanning the border of Rwanda and the Democratic Republic of Congo, Mount Karisimbi is the highest volcano in the Virunga range at 4,507 meters (14,783 feet) and the fifth highest mountain in Africa. The subalpine and alpine zones are teeming with Rubus (blackberries) and Dendrosenecio. Along the trek up, the team passed what Dian Fossey described as many “barren, moon-like alpine meadows of Karisimbi” and continued to climb higher in elevation. The field team found the group’s night nests at 3,680 meters, but continued upwards to find the four gorillas that remain in Inshuti’s group. The team moved quickly from the start, knowing that Inshuti's group was ranging far, confident in their many hours of experience on the mountains. But the quick ascent backfired, and Eckardt reported that altitude sickness had set in by the time the team reached the nest site. An unsettling nausea gripped the hardened gorilla researcher and her legs felt as if they had turned to stone. It’s extremely cold, windy, misty and wet at this altitude and the gorillas too struggle in such difficult conditions. The field team reported that infant Akaruso, after losing his mother when she transferred to Giraneza’s group in February, continues to sleep with Inshuti. The silverback had built a deep, thick nest to deflect the cold wind. Another equally deep nest where Shangaza and infant Ngwino had slept was nearby. In her book Gorillas In The Mist, Fossey described other gorillas retreating to Karisimbi’s slopes during her research. Lone silverbacks Bartok and Brahms both chose ranges on Karisimbi. And, when Brahms was shot in the chest by a poacher’s bow and arrow in 1971, he retreated up Karisimbi and stayed for an entire year before he successfully obtained two females and formed his own group.

A Staring Contest with Buffalo

Bwenge’s group encountered a herd of buffalo today in the Kupoteza area of Volcanoes National Park (in the saddle between Mount Karisimbi and Mount Visoke), reports Karisoke researchers Winnie Eckardt, Ph.D. and Stacy Rosenbaum. When the two researchers arrived at the group this morning, the gorillas were huddled together and staring intently at something. Rosenbaum’s first thought was “lone silverback." But as it turned out it was a herd of 14 buffalo -- calves, mothers and old males, staring right back at the curious black creatures.

After a considerable staring contest ensued, the adult gorillas lost interest and resumed feeding.  The youngsters of the group, determined to “defend” their family, confidently strut-stanced back and forth in front of the ambivalent bovines, periodically chest beating to make their message clear.

Two-year-olds Gasore and Ubuhamya, along with 4-year-old Ntaribi, continued their posturing for a while, slowly inching closer to the buffalo until Nzeli (mother of Ubuhamya) sauntered up and grabbed her infant, bringing her back to the group. Eckardt, who is studying stress in mountain gorillas, said that the group “didn’t seem to be stressed or bothered by the buffalos' presence at all. They were definitely interested in them." After an hour had passed - and both species had ruled each other out as a potential threat - the animals went their separate ways from the meadow.

Lone Silverback Drama Continues for Inshuti

The lone silverback drama involving Inshuti and his group has continued on through the end of this week, reports the Fossey Fund’s Karisoke Research Center field staff. The dominant silverback truly cannot catch a break from the lone males ranging in the forest tenaciously seeking out females to steal. Yesterday, Karisoke researcher Winnie Eckardt, PhD. and research assistant Samedi Muyco witnessed an interaction that lasted from early morning to late afternoon and had the females of the group shaking with fear. This particular interaction involved Giraneza, an impressive lone silverback who split from Pablo’s group four years ago when he was just 13 years old.

But Giraneza wasn’t the only lone silverback threatening Inshuti’s group on Thursday. Also on the trail was Tuyizere, the lone male who has been making frequent appearances in the Karisoke-monitored groups throughout the last several months. When the field team arrived, Tuyizere was interacting with the group, but was quickly deterred by the team’s presence and lingered about 100 meters from the rest of the gorillas for the duration of the afternoon. Giraneza more than made up for Tuyizere’s reluctance with a constant onslaught of displays toward the group leader. The mammoth Inshuti responded with intimidating displays of his own and charged Giraneza multiple times throughout the data collection period.

Young female Nyandwe “was very interested in going with Giraneza” said Eckardt. "She was frequently looking at the lone silverback. Inshuti had the hardest time to move her up and away” from the intruder. Eckardt reported that the group leader was working hard to move his females higher up the mountain for most of the day, but Nyandwe took her time and was noticeably lagging behind. Eckardt observed one instance where Nyandwe was keeping an eye on both males. When she saw that Inshuti had moved higher up with the rest of the group, she started making her move towards Giraneza. But, Inshuti caught her and moved quickly back down to guard his female. Nyandwe feigned disinterest in the lone silverback and followed Inshuti back up to the group. And it wasn’t only Nyandwe that had an eye for Giraneza. Female Taraja was also very interested in going with him, but with her young offspring still in tow, she likely reasoned it wasn’t a good idea to attempt to transfer at this time.

Field Data Coordinator John Ndayambaje reported that Inshuti’s group was peaceful this afternoon and no lone silverbacks were found on their trail. Hopefully this will mark an end to the incessant intruders and Inshuti will have time to heal from his wounds.

Group Leader Isabukuru Turns on Beta Male

Isabukuru fought Kubaha Monday, reported Karisoke Research Assistant Jean Paul Hirwa. The researcher noticed that Isabukuru was clearly uncomfortable with Kubaha’s presence yesterday morning when the field staff arrived at the group, and the dominant male was keeping a close eye on the beta male. Kubaha lingered about 10 meters from the group for a short while before Isabukuru confronted him.

When Isabukuru approached Kubaha, the beta male “pig grunted” towards him in warning, but Isabukuru advanced on him, initiating a short bout of “kick-hits." It was clear that Isabukuru had “defeated” Kubaha when the dominant silverback had him pinned to the ground screaming, with Kubaha assuming a cowering posture. Kubaha attempted to make his escape, but Isabukuru held him down, mouth open wide and teeth poised above his opponent. The females of the group were equally aroused and Ikaze bit Kubaha in a moment of excitement.

Isabukuru rounded out the incident with a vigorous display towards Kubaha, then “kick-hit” him before allowing him to go. Kubaha immediately started moving away from the group and was feeding very far from Isabukuru’s group when the observation and data collection period came to a close. The Fossey Fund field staff was unable to detect any serious injuries on Kubaha, however a wound was seen on his right arm from Ikaze’s bite. Karisoke researcher Stacy Rosenbaum made plans to trek to the group the next day to collect data and report on the group dynamic. More to come.

Injured Silverback Inshuti in Stable Condition - Fossey Fund Blog Post

Karisoke researcher Winnie Eckardt, Ph.D., accompanied the team assembled to assess the condition of injured dominant silverback Inshuti this morning. Eckardt reported that “although his injuries are indeed severe, the group leader appears to be toughing it out -- in typical Inshuti style” and a medical intervention was not necessary. She added “overall, the group appears to be exhausted from the incident and was traveling slowly, stopping frequently to rest.” With Inshuti injured, adult female Shangaza took the initiative to lead the group away from the one lone silverback who was still on the trail of the group.

Inshuti grooming himself.

Karisoke trackers were able to successfully identify this remaining lone silverback as 21-year-old Turatsinze -- the same male that participated in an interaction with Titus group last November in an attempt to acquire female Ubufatanye (Fat). Turatsinze has been a lone silverback since 2006 when he dispersed from Pablo group on Oct. 18 of that year. It appears that he has traveled solo long enough -- and is anxious to start his own group.

And Inshuti is all too familiar with Turatsinze’s struggle. Interestingly, Inshuti is one of the few lone silverbacks observed by the Karisoke Research Center to build a group “from the ground up,” gradually acquiring one female after another. Eckardt reflects that he was “incredibly tenacious and tough. He wasn’t going to give up until he had formed his own group.” It appears that same strength and tenacity has served him well in keeping his group together.

Inshuti was observed directing “neigh vocalizations” towards female Taraja three times this morning. This could provide some insight as to what lured the lone silverbacks to his group. Over the last week, Inshuti was seen copulating with the female, which could indicate that she may be able to conceive again. Inshuti’s “neigh vocalizations” could have been an attempt to strengthen the bond between the pair, and deter her from leaving his group to accompany the lone silverback.

Inshuti was feeding very little today and his condition must be monitored closely throughout the next several days by Karisoke field staff. MGVP veterinarians will visit the group again Tuesday to ensure that he is recovering smoothly. As for Turatsinze -- the lone silverback was 700 meters from the group when the team left this afternoon and moving in the opposite direction. Trackers will continue to search for the missing lone silverback for identification purposes.

Silverback Leader Inshuti Attacked by Two Lone Silverbacks

Silverback Inshuti

Two lone silverbacks joined forces and attacked 24-year-old dominant silverback Inshuti today, reports Fossey Fund Field Data Coordinator John Ndayambaje. Inshuti sustained three large bite wounds on his head and one on his neck. Veterinarians Dr. Dawn Zimmerman and Dr. Jean-Felix Kinani (of the Mountain Gorilla Veterinary Project), along with a team of Karisoke trackers, will trek to the group tomorrow to assess the damage and potentially carry out a medical intervention. Karisoke researcher Winnie Eckardt, PhD., will join the team to collect behavioral data and fecal samples for her ongoing study on stress in the mountain gorillas.


Ndayambaje reported that the interaction began in the Tamu area between Mount Visoke and Mount Karisimbi at 11:24 a.m. and lasted almost 2-1/2 hours, until the pair of silverbacks retreated from the group at 1:49 p.m. The unidentified silverbacks displayed 19 times throughout the first half of the interaction, pushing Inshuti and his group to travel over 1.5 kilometers through the forest, in an attempt to get away from the intruders. Inshuti displayed three times before the physical interaction began, when he sustained the bite wounds.

With the absence of any other males in the group to help Inshuti, the three females, Shangaza, Taraja and Nyandwi, participated in the interaction in defense of their infants and injured leader. The two infants remained on their mother’s backs throughout the entire interaction -- which the field staff found particularly interesting because, at almost 3 years old, both offspring are at an age that they would not normally need to travel on their mothers' backs. Females Shangaza and Taraja reportedly charged the two silverbacks twice. On the first occasion, they charged both silverbacks jointly, causing the males to turn and retreat. Next, they charged only one of the silverbacks, at which point, the other male charged the females, who then retreated. During this time, Inshuti attempted to display, but was too weak to chest beat and was only able to display with hooting vocalizations. Inshuti group trackers report that the pair of silverbacks are 350 meters away from the group at this time. Inshuti is said to be in critical condition and appears to be in quite a lot of pain.

Although the attackers are not yet officially identified, the field staff believes these two silverbacks could possibly be 15-year-old Gushimira and 14-year-old Twihangane, the gorillas that dispersed from Pablo group on August 16. However, there are currently six lone silverbacks that are monitored by the Karisoke Research Center in this area and realistically, the aggressors could be any of them. Along with the medical intervention team for Inshuti, another team of trackers will enter the forest tomorrow morning to track the silverbacks and attempt to identify the individuals.

Gorilla Program Manager Veronica Vecellio says that “this is not the first time that Inshuti has been involved in such an aggressive interaction -- he suffered serious wounds from both Beetsme and Pablo (late silverbacks) in the past. He is a strong individual and he will likely bounce back from this.”
Our Karisoke staff is, of course, enormously concerned and hopes that Inshuti will recover from these injuries. Without Inshuti, this group would be in disarray, with the two infants of the group in an extremely vulnerable position.

An account of tomorrow’s observations and possible medical intervention will be reported promptly.

The Atypical Silverback: A Profile of Isabukuru

“Isabukuru has always been one of my favorite animals - even years ago when he was just a blackback in Pablo’s group - because all of the females absolutely loved him” says Karisoke™ researcher Stacy Rosenbaum, who is currently carrying out a study on paternal investment in mountain gorillas. “I always knew that he would lead his own group as a dominant silverback someday.” These days, Isabukuru is a primary focus of her paternal investment study, because not only females are drawn to him, but also the youngsters.
“Isabukuru actively seeks out interactions with kids in a way that I’ve never seen another silverback do” says Rosenbaum. The gigantic silverback has been observed carefully carrying the tiny infants clutched to his chest, engaging in play behavior and patiently tolerating the youngsters’ antics like no other adult male would. Rosenbaum says that it is not uncommon for the young ones of his group to climb on top of his broad chest during the group’s resting periods, where they will attempt to push each other off in a lively game of “king of the hill.” The field staff all emphatically  agree that there is no other male gorilla monitored by Karisoke in the last decade that has taken such a great interest in his offspring.

Breaking out on his own

Maternal brother to Cantsbee, the renowned 33-year-old dominant silverback of Pablo’s group, Isabukuru possesses many of the same attributes that make Cantsbee so endearing to humans. Cantsbee is also extraordinarily tolerant of the youngsters in his group and can often be seen with a string of fluffy infants on his trail. However, when it comes to play time and deliberate interactions with the little ones, it is clear to all of the field staff that Isabukuru takes the cake for “dad of the year.”
The “Don Juan” of mountain gorillas, Isabukuru frequently found himself in trouble with older brother Cantsbee during their time together in Pablo’s group. Even though Isabukuru was still just a blackback, he was exceptionally large for his age. The female gorillas were crazy about him and pursued him at every opportunity. As alpha silverback of the group, Cantsbee held strict mating rights and was not pleased when his little brother would mate with the females.
Fortunately for both brothers, an interaction between Susa’s and Pablo’s groups on June 26, 2007 allowed for Cantsbee to be free of his sibling competition and Isabukuru to break out on his own and start a new group. Four females, Icyizere, Muntu, Muganga and Ishema, transferred from Susa’s to Pablo’s group during the interaction. The next day, Pablo trackers returned to the forest to find only Ishema still within Pablo’s group. Isabukuru had left - taking his three newly acquired females with him. He was just 14 years old.

An interesting group dynamic

Kubaha, beta silverback (and the only other male) is an unusual member of Isabukuru’s group. Kubaha serves as the “watchdog” and can usually be found well outside of the group or traveling peripherally. Isabukuru does not allow Kubaha to mate with the females or play a strong role in the daily group dynamics. Only when confronted with the threat of another group or a lone silverback will Isabukuru join forces with Kubaha to defend the females and youngsters.
The dominant silverback’s wariness of his beta male could likely stem from an unfortunate incident of infanticide that occurred in July 2010. Isabukuru had traveled almost 600 meters away from his group to confront a lone silverback before the intruder could reach his females. While he was away, Kubaha attacked female Bukima and her seven-month-old infant Agatako (presumably Isabukuru’s offspring). The blackback bit the youngster and he died instantly.
Gorilla Program Manager Veronica Vecellio admits that Isabukuru’s tendency to leave his group unguarded is atypical for dominant silverback behavior. However, both the male and his female group members appear unperturbed by the occasional separation. The field staff hopes that this behavior won’t invite another such incident sometime in the future, but only time will tell.

Relaxed leader, relaxed group

One thing is certain. With a tolerant and relaxed silverback like Isabukuru often comes a more relaxed group of gorillas. Rosenbaum says that to her, one of the most distinguishing characteristics of Isabukuru’s group is the amount of “group play” she observes. The researcher says that all of the adults within the group engage in play behavior on a regular basis, not only with the infants, but also with one another - a rare occurrence among mountain gorillas.
Female gorillas, youngsters or human observers - it seems that no one escapes Isabukuru’s charms. Stay tuned for a photo essay on the endearing silverback and his offspring in the coming weeks!

A Most Persistent Solitary Silverback

The Fossey Fund’s Karisoke™ Research Center routinely monitors nine groups of mountain gorillas. Ranging in the same area are six well-known solitary silverbacks that make appearances from time to time when they are searching out social groups in hopes of attracting females. By the end of 2011, Karisoke researchers had recorded 82 encounters with a lone silverback, 54 of which were active interactions with a social group. These interactions happened under a variety of different scenarios and lasted anywhere from mere seconds to an entire day, to weeks on end. While these silverbacks are frequently alone, they are almost always on the trail of another group, biding their time to make a move.

The behavior of the lone silverback

Solitary silverbacks spend several years - and sometimes their entire adult life - traveling alone. The young males are born and raised in the safety of a gorilla group, but as they grow into adults and the characteristic silver hair begins to show on their back, the desire to become dominant can cause them to strike out on their own. The silverback will then begin a lonely quest that may last for years, peppered with dramatic interactionss. Throughout that time, the lone silverback will periodically pursue a social group, usually with his eye on a specific female he would like to acquire. Displaying and vocalizing dramatically, he can push the group’s dominant silverback to react aggressively, sometimes resulting in violence or injury. More frequently however, the field staff observes "auditory interactions" between social groups and the lone silverbacks. This occurs when the lone silverback announces his presence with intimidating chest beats and hooting vocalizations, to which the silverbacks within the group will respond accordingly. Sometimes the interaction will end there, if the group is successful in discouraging the outsider.

Will persistence pay off?

Without a doubt, the most tenacious of these six lone silverbacks has been Gwiza, whom Karisoke trackers encountered 31 times in 2011. Gwiza left Shinda’s group in April 2004 when he was 16 years old. During the past eight years he has been observed traveling alone. Interestingly enough, since the death of dominant silverback Shinda and the subsequent group split, Gwiza’s interaction frequency has increased dramatically. The lone silverback routinely targets Ugenda’s and Ntambara’s groups (the two groups that resulted from thebreakup of Shinda's group). It seems that, despite his decision to live and travel alone, silverback Gwiza still does not want to stray too far from his origins....

Gorilla adoption makes a great gift for the holidays!

Top 5 Reasons to Adopt a Gorilla Through The Fossey Fund:

1. Ensure our anti-poaching patrols work 365 days a year in 2012.
This year some of the gorilla groups we monitor spent long amounts of time outside the protected park, feeding on seasonal bamboo and other plants at the lower altitudes. Without the money raised from adoptions, we would not have been able to protect them around the clock as they wandered around.

2. Ensure the continued growth of the mountain gorilla population.
Fewer than 800 mountain gorillas remain on the planet. However, the mountain gorilla is the only type of gorilla growing in population. Help keep this momentum going!

3. Receive an adoption certificate and profile about your gorilla.
Have the unique opportunity to learn more about one of the gorillas we monitor on an intimate level. Each adoption comes with a profile that includes detailed information written by our expert field scientists about your gorilla. You’ll also get special access to a gallery of Karisoke and GRACE center gorilla photos, stories and profiles.

4. Gorilla adoption makes the perfect gift for hard-to-buy-for friends.
Stumped about what to get a friend, family member or colleague? A gorilla adoption makes the perfect feel-good gift this holiday season. Here’s what Fossey supporter, Cindy Broder, says, about her Adopt giving:

“This past holiday season I was thinking about gifts for friends and my husband’s clients, and I wanted to express our love and appreciation for them in a more meaningful way. So, I read about the gorilla adoptions, with their different choices and levels of giving. I chose to give silverback adoptions because they are so awe-inspiring that I think they make the best introduction to the gorillas."

"The response was incredible! There wasn’t one person who didn’t write and say it was the best thing anyone had ever done for them. Some of their children drew pictures of the gorillas on the thank-you cards. One friend joked that he was adding on a suite to his house so his silverback and family could come visit! It just touches peoples’ hearts in such a different way, no matter how many incredible experiences they have had.”

5. Know you are part of the solution.
The top threats facing the mountain gorilla population are all from humans: poaching, habitat destruction and disease. Be a part of the group of people that helps counter these threats and saves an important species from extinction.

Don’t let this holiday season go by without doing your part to save the gorillas you care about...

Many Possible Outcomes for Gwiza / Titus Group Interaction...

After the 17th day of interaction between Gwiza and the Titus group of gorillas, led by silverback Rano for the past two years, the situation’s outcome remains unclear. According to the Fossey Fund’s Gorilla Program Manager Veronica Vecellio, many different scenarios could unfold. The gorillas have already begun to group together and then regroup, resulting in several different formations as both Gwiza and Rano have assumed the role of lead silverback.

The field staff observed Gwiza leading all but two silverbacks (who remained with Rano) at last week’s end. Today however, the group members are rejoined with Rano while Gwiza and female Fat are resting, feeding and nesting together, 15-20 meters from the group. It is possible that the couple could split off on their own, starting a new research group of gorillas.

Unfortunately, infanticide is yet another possible outcome of this situation and the field staff are concerned about pregnant female Imvune. If Gwiza decides to stay, moving into the dominant silverback position, and Imvune gives birth, it is likely that Gwiza will kill the infant (who was clearly sired by another male).  Fossey Fund Karisoke researchers plan to conduct another pregnancy test on Imvune to ensure that she has not miscarried from the high amount of stress the group has been under during the last several weeks.

Pablo Group Comes Down To Lower Altitudes

After a month of cold temperatures, frequent rains and thick mist on Kimbagira, the 45 gorillas of Pablo group have finally moved down into the bamboo zone.  It was a beautiful day for their arrival into the lower altitudes of the park; the sun shone brightly and the gorillas appeared to relish the warmer weather. Fossey Fund Karisoke researcher Dr. Winnie Eckardt was with the group when they arrived in the bamboo belt at 12:30pm this afternoon, with dominant silverback Cantsbee in the lead. Eckardt reported that the gorillas fanned out, in search of the best patches of bamboo shoots. The youngsters of the group were busy engaging each other in games of chase and other playful activities and the adult gorillas happily feasted on succulent shoots nearby. The scene was a stark contrast from the previous week’s observations - where every gorilla was huddled and shivering in the cold rain, high up on Kimbagira....

Silverback Cantsbee Found In Good Health

Karisoke researcher Stacy Rosenbaum brought great news down from the mountain today: our elderly silverback Cantsbee seems to be just fine, feeding and behaving normally again.
When the field team reached Pablo's group this morning, Cantsbee was in a new, leafy day nest about 200-250 meters up from where Dr. Eckardt’s team had left them yesterday. The 32-year-old silverback had evidently risen from his night nest and traveled up the slopes to meet the rest of his group yesterday evening. Rosenbaum reported that when she arrived she saw Cantsbee, along with all of the other gorillas, hunched over and shivering, apparently miserable from the extreme cold and constant rain...

The Bamboo Season

With the onset of Rwanda’s biannual rains, it is time for the bamboo season in Volcanoes National Park, when many of the mountain gorilla groups monitored by the Fossey Fund’s Karisoke™ Research Center make their way down to the “bamboo belt” near the park’s border. The Bwenge, Titus, Ugenda, Kuryama, Ntambara and Urugamba groups have already been observed at lower altitudes in the park, tempted by the prospect of tasty bamboo shoots.

When the groups of gorillas converge on the bamboo zone at the border, we are bound to see two things: an increase in interactions between groups and gorillas leaving their protected forests to venture out into the surrounding farmland....

New Mountain Gorilla Census Underway in Uganda

"In the past, there has been much debate about the Bwindi gorillas’ classification. Veronica Vecellio, Karisoke’s Gorilla Program manager, explained that the Bwindi population is of particular interest to primatologists because “they exhibit enough ecological and morphological differences from both Grauer’s gorillas and Virunga mountain gorillas that they could one day be classified as a separate subspecies.”
