We conducted a waterbird census on Lake Borogia and Lake Baringo on the weekend of 7th and 8th July 2018 as part of the bi-annual Waterbird Census. This was coordinated by the Ornithology Section of the National Museums of Kenya, Nature Kenya (the East Africa Natural History Society) and the Baringo County Government. Here are some photographic highlights from the census:
Water levels were high at Lake Bogoria and some of the roads alongside the lake were completely flooded, but flamingos still found the conditions favorable for feeding and the lake was covered with them!
We counted over a million flamingos on Lake Bogoria. Most of them were Lesser Flamingos, with a handful of Greaters among them
Nearly half of the flamingos were juveniles, clearly distinguished from the pink adults by their pale greyish plumage
There were plenty of immatures as well (whitish without red in the wings). The adults themselves made up a small proportion of the birds present
Greater Flamingo (taller with pink bill) among the Lessers

Verreaux’s Eagle Owl
The rise in water levels is even more pronounced at Lake Baringo and numerous camps, lodges and properties have been flooded. Extensive areas of flooded Acacia woodland have provided plenty of dead trees for darters, cormorants, herons, egrets and other birds to nest in. This lake however has no flamingos at the moment (only one Greater Flamingo was seen).

Teams head out to begin the count
Each team has its own section of the lake to count
One of our first sightings at my team’s count site on the eastern shore – African Fish Eagle
Probably Africa’s most iconic and photographed bird of prey
Lousy image but a great sighting. African Fish Eagle being mobbed by an Osprey! The Osprey is a Palearctic migrant, which means it “shouldn’t” be in Kenya at this time of year. But a few non-breeding individuals always remain year-round. Other Palearctics seen were White-winged Tern, Gull-billed Tern and Barn Swallow (all at L Baringo). We also saw a few White Storks near the donkey slaughterhouse on our way back to Nairobi.
Large dead trees were scattered all over the area around the Mukutan River mouth

A testament to the ever-changing and dynamic nature of the Great Rift Valley and nature overall
From a photographic perspective though, the dead trees on the lake under the wide open sky make for great landscape shots

Northern Masked Weaver. A scarce weaver in Kenya, only occurring in the northern Rift Valley, with Lake Baringo being the best place to see it.
Breeding colony of African Darters taking advantage of the dead trees. Reed Cormorants and Striated Herons were also breeding among them

We saw one hippo but they are apparently common in the shallower parts of the lake

Squacco Heron in breeding plumage. These, along with Striated Herons, were the most numerous herons our section. Although we didn’t see any Squacco Heron nests.
African Harrier-Hawk with a very red face – a sign of excitement. It had been busy raiding African Darter nests nearby.
More nesting darters

One threat to Lake Baringo’s biodiversity is the invasive Water Hyacinth. Some parts of the lake are covered in it and it is reportedly impacting the lake’s fish populations

In additional to waterbirds, I also recorded terrestrial birds opportunistically along the way to submit to the Kenya Bird Map project (using the BirdLasser app). I managed to record 125 bird species in total across 11 pentads – including 2 full protocols at L Bogoria and 2 at L Baringo. Some counters on the other teams also recorded BirdLasser lists, which made for some good coverage of the 2 lakes. I had 3 lifers on this trip: Northern Masked Weaver, Northern Grey Tit and Bristle-crowned Starling!
