Another early morning at Elsamere field study center!  We started our day at Hells Gate National Park.  Large cliffs perimeter the park and are also a very common nesting sights for raptors. Not until you stand next to the cliffs do you really appreciate its vastness.

In order to see the raptors in the cliffs, binoculars were needed and even then the birds were quite small.  The only way we could really see the birds well was through a telescope!  It was awesome watching the birds in their natural habitat.  We saw Verreaux’s eagles, Lanner falcons, harrier hawks, augur buzzards, and even Ruppell’s vultures.  Clearly, Hells Gate is a haven for raptors!
The park is also home to two gorges; an upper gorge and a lower gorge, which were formed in part to flooding and El Nino storms.  Lake Naivasha used to reach the top of the gorges; 100 meters higher than it now sits today!  A man named George, a member of the Massai tribe, guided us through the gorge.  George, who carried a walking stick made from camphor tree, was very knowledgeable about the area and aided us in climbing the tricky and slippery rocks.  The walk through the gorge was beautiful!  It’s amazing what nature can do.

After our hike through the gorge, we got on the bus and headed to two of KenGen’s geothermal plants.  KenGen is an electricity company that produces geothermal, thermal, hydro, and wind energy.  This plant is the only energy plant in the world that lies in a national park.  Cyrus Karingithi, Assistant Manager of Resources Development at KenGen, guided us around the plant. The plant smelled strongly of sulfur and was very noisy. Although the plant was smelly and loud, it was fascinating to see the ins and outs of a power plant.
The group discussed energy usage in Kenya with Cyrus.  KenGen wants to increase their wind and geothermal usages.  In order to do so, they need to build more sources.  KenGen plans to build a geothermal plant at the exact spot that we set up a telescope today in the park viewing raptors.   Wind energy, although a very clean sources of energy, kills birds as they fly into the turbines.  Unfortunately, raptors are not the first priority for KenGen when deciding where to set up their next plant.  Hopefully someone can conince KenGen to take the raptors into consideration.  Maybe a student’s work can convince them!

What a great day all around! Looking forward to a lecture from the editor of Swara magazine and a trip to Soysambu!

Not far from Elsamere and Lake Naivasha is Hell’s Gate National Park, named after a narrow chasm among striking red cliffs that was once a tributary to a prehistoric lake in the Great Rift Valley. We begin on foot, and after days of cloudy weather and a bit of rain, the morning is clear and glowing with light that is perfect for photography. Our feet kick up fine dust, the remains of ash from nearby Mt. Longonot, which is dormant. Chunks of obsidian are shiny beneath the dirt.

In the distance, steam spurts from the horizon accompanied by a loud hum that indicate the Olkaria Geothermal Station, the first of its kind in Africa, established in 1981 and operated by KenGen, the leading power company in Kenya. There’s a huge push underway in Kenya to use renewable energy, but even this comes at a price. The water needed to operate the plant came from Lake Naivasha until the company began to dig boreholes. All power, ultimately, comes at some price.

The natural geothermal energy heats up spring water, which seeps from crevices and cascades down in small waterfalls, smelling strongly of sulfur. We explore the canyon, learning new plants, insects and amphibians.

Hell’s Gate is a heaven for birds of prey. Munir tells us about Simon Thomsett’s attempt to reintroduce bearded vultures back to the park and shows us the remains of the hacking site. A pair of Verreaux’s eagles cruise together across the sky to the north, back to the south, over to the west, landing briefly on the ground at a ridgetop near their nest before heading off again, coasting on the wind. We see a lanner falcon, perched near its nest at the top of a sheer cliff.

We also learn how poorly designed watering holes can be fatal for birds of prey.

We climb in the Land Cruiser to head deeper into the canyon, pausing to have a tea break under the tree where famous raptor biologist Leslie Brown sat to study a colony of cliff-nesting Ruppell’s vultures. The cliff is covered with whitewash, but there are only so many ledges. There are vultures on nests and vultures flying on wide plank-like wings eight feet tip-to-tip. Munir has counted up to 60-70 birds at a time at this site. Teeku sets up his 600mm lens and we take turns getting close-ups of the birds from a great distance, then we climb up to the base of the cliffs, searching for prey remains and feathers and eggshell fragments. We also get a spectacular view, spotting giraffes, marred only by the billows of steam and noise rising from the KenGen plant.We discuss how a park that is only 60 square kilometers can be so rich in raptors and plains game but also at odds with surrounding agricultural, pastoral and horticulture pressure.

We then hike down into the chasm of the canyon itself.

The rockclimbers of the group (Chris, Brian and Drew), cannot contain themselves!
