Lion Collaring Expedition - Day Three

As you can imagine by this point in the process... slowly the team started to get a little anxious, time was definitely running out. Two days without collaring a lion: the pressure was on with only a few more days left.

We decided to change our strategy so in addition to the sound playbacks, we used bait as well. We obtained two goat carcasses that were killed by lions the previous night in Oltiasika to attract lions, in addition to the call up sounds. More than an hour before dark we arrived at the calling station site close to where we saw the lion the previous night. The stomach of the goat carcass was punctured and the carcass was dragged behind the car in a 100 meter radius around the location of the calling station. After dragging, the carcass was hung high into a tree close by.

Even before we started playing the sounds, the first spotted hyena showed and we feared the area would soon be infested with spotted hyenas. Then a pair of jackals started barking in the distance and all the spotted hyenas left the area.

Night fell, and so we started playing the sound of a buffalo calf in distress followed by the pig squeal. After more than 3 hours of calling we started to worry that the lions would not come at all. Then suddenly a large growl of a lion was heard next to the vehicle. Everybody in the team that has collared a lion before knew what that meant... a lion was hit by a dart. A rush of adrenaline and excitement. We got it!

Spotlights were switched on and the cars drove around through the bush in search of the darted lion as it ran off into the long grass and dense bush for safety after being hit by the dart. Fortunately, the KWS team spotted the lion, 150 meters away from the darting site.

The KWS vet drove the car close to the lioness and poked it with the dart gun to ensure it was properly sedated before we got out of the car to start the collaring. Measurements of teeth, paws, nose-tail length, shoulder height was taken. Was had approximately 45 minutes to do the job white MWCT rangers and Simba Scouts were on the lookout for possible other lions in the area that might have come to the rescue.

It was a young lioness of about 3 years old in a healthy condition. She was named Namunyak meaning "lucky one". To further boost her condition Dr. Poghon injected some vitamins and antibiotics, and also treated her for ticks and lion lies. When everybody was finished, the antidote was given. A MWCT car was called to come with new Simba Scouts to monitor the recovery of the lioness to ensure she was not harassed by hyenas or other lions that may wish to take advantage of her vulnerable state.

After the collaring of Namunyak, the collaring team proceeded to another location where Simba Scouts had seen 5 lions earlier that day. The team stayed out calling up to 5:00 a.m. but no lions showed up, in which they decided to head back to the camp. At that time we received a message from the Simba Scouts that the newly collared lioness had fully recovered and moved safely into the lava bushland. A good sign, as this habitat is a safe hide-out for lions on Kuku Group Ranch.

Lion Collaring Expedition - Day Two

The Conservation Team shares the next days' events in the lion collaring process!

The lion collaring operation continues onto day two! We decided to still push for the collaring of the lone female lion close to the Campi ya Kanzi airstrip. During the day time, Dr. Poghon collected night vision equipment from the rhino sanctuary in Tsavo West National Park to avoid the use of spotlights that might put off lions and increase our capability to detect lions. We help the first call up close to the airstrip, but now in an area with a few more shrubs to cover the visibility of the two vehicles. We decided to no longer use the sounds of feeding hyenas as it attracts too many spotted hyenas, which may in turn intimidate a lone young lioness to come.

Just before dark, shortly after we started playing the sound of the pig squeal, the lioness suddenly appeared and walked around the cars, but then quickly disappeared again into the bush. Everyone including the vet was caught by surprise as we did not expect the lion to react so quickly. Unfortunately the vet did not manage to dart the lion before it disappeared out of range. The lioness was very cautious and stayed on the periphery for almost two hours sitting and looking at us, but not daring to come close.

In a desperate attempt, the vehicle started and the vet tried to move towards the lioness. Unfortunately the lioness sensed danger and disappeared into the darkness not to return again.

Although a bit disappointed that we did not manage to collar the lioness, our hopes raised as there was a lion in the area attracted by our calling station.

Later that night we spotted three pairs of red eyes along the road on our way to the next call up site, and so decided to do another calling station close to the Campi ya Kanzi lodge. During this calling station, spotted hyenas showed up, and a leopard!

Four hours later we moved to our last location of the night near Longido. After a few hours without seeing any predators and again a lot of rain, we decided to stop.

Surely the next night we would have better luck...

Lion Collaring Expedition - Day One

Continued description of the intricate lion collaring process that occurred just recently. This is what happened on Day 1!

In the morning before the Kenya Wildlife Service (KWS) vet arrived, MWCT rangers discovered zebra carcass close to the Chyulu Conservation and Research Center (CCRC). It was not killed by predators, but died of natural cause and it looked like perfect lion bait. In the late afternoon, when the KWS vet arrived, he inspected the carcass and rejected it, as it might have died from anthrax - a dangerous but common disease among wildlife in Kenya.

On the first night of the collaring operation, we went to the airstrip of Campi ya Kanzi and played sounds of warthogs, buffalos in distress, and feeding hyenas to attract lions within the vicinity. Except for over 10 spotted hyenas and a pair of black-backed jackals, no lions showed up (although we were pretty certain they were in the area as there had been regular sightings by Simba Scouts and Campi ya Kanzi personnel). There can be many reasons for a lion not responding to a calling station. When lions are full after feeding on a carcass, it is likely that they will not respond to a buffalo calf or a warthog in distress. Furthermore, lions can move large distances during one night (more than 15 km) and resting places can be different every day. After 4 hours of calling, we decided to relocate to a new position.

This map indicated the locations of the calling stations.
The yellow circles indicate calling station positions without lion sightings. The pins indicate the positions where fresh lion tracks were found; blue pins vare verified observations by conservation managers; organs pins are Simba Scout lion observations; green pins are community observations; and red pins indicate location of livestock predation incident by lions
The second position was closer to the seasonal river. Again, drooling spotted hyenas came running towards the sound, expecting a nice meal. After 4 hours of calling, there was still no sign of any lions. We decided to try our last location near Longido to attract some of the lions that have visited the waterhole at Campi ya Kanzi the previous week. During this call up, heavy rains set in and after an hour it was decided to call it a day and go back to camp. The rains prevented the sounds from travelling a big distance and the visibility became constrained.

After this first night, we realized that the task to collar lions on Kuku Group Ranch is by no means an easy one...

Stay tuned to the blog for what happened next!
