This morning, we were divided into two groups to trap and band birds on and around Lake Naivasha. The first group, led by Shiv and Meera, worked to catch African fish eagles on the lake, while the second group, led by Teeku and Munir, went for a long drive around the lake. The bumpy dirt roads, taking us through villages and past open fields, allowed us to slowly survey the area for Augur Buzzards.  We set out traps for the buzzards containing small white mice, aptly named Stuart and Little (and Stuart was clever–he kept trying to make a break for it!)

By the end of the day, we had spotted a total of thirteen Augur Buzzards, two unidentified raptors, an African long crested eagle, two unspecified vultures and a kite. We also had the opportunity to band a bird, number D1859, with Liz and Kaitlin taking the opportunity to hold and band the buzzard.

Tomorrow, the groups will switch locations, so everybody will have the opportunity to encounter the different species.

We spent the last two days trapping birds on and around Lake Naivasha. One group loaded up in the van and drove the road that circumnavigates the lake to do a road count of resident raptors with the hopes of trapping and banding some while the other group climbed into boats armed with fish to trap African fish eagles. The next day, we switched.

A brave little mouse was our lure on land. Safe within its cage that was set with fine fishing line snares, an augur buzzard immediately descended, got tangled, and Munir and Evan jumped to release him.

Banding, or ringing, of birds helps biologists track bird populations over time and geography.

It’s also a chance to experience and learn about the birds up close.

As its mate waits in a nearby tree, the buzzard calmly lets us affix the ring to its leg.

Meanwhile, on the water, Shiv leads the African fish eagle trapping. First, Shiv shows us how to get our hands dirty, using a carp fish as a lure and setting snare lines through it.

Fish eagle populations are doing well at Lake Naivasha, but only more studies will determine whether they are being effected by pollution, changes in the ecosystem and water quality, or the lead that remains from decades of bird hunting on this lake.

In the afternoon, we visit two flower farms to see their wetlands water filtration system. Homegrown produces both flowers and vegetables.  Oserian is one of, if not the largest flower farm company in Kenya, and a major player in the Naivasha region. Representatives from Oserian came to Elsamere to make a presentation about their company’s ethics, mission and policies. Both companies raise interesting questions about fair trade certification and what it really means. Oserian was proud that they are paying their full-time workers 7,900 shillings per month, which is about a hundred dollars US. Some workers also receive housing, school for their children and health care, but a hundred dollars is still not much money for a month’s labor.

As for their environmental practices, both companies claim to not use WHO Class I pesticides, listed as extremely hazardous. Oserian opts for Integrated Pesticide Management (IPM) instead. What chemicals they are using to produce a million stems of cut flowers each day, though, they refuse to reveal. Both site visits displayed a small area with a series of water containment areas that were filtering not the water coming from the flower production area, but the water from the kitchens, laundries, etc. It was impressive, visually, going from this:

But where is the rest of the water that makes it back to Lake Naivasha, untreated and unfiltered? And what, exactly does it contain? What might be in the bodies of the fish that are caught and eaten from the lake? No one, at this point, seems to know.
