Dreaded Parthenium in NNP

By Will Knocker:

DSCF5403

The dreaded Parthenium Weed -spread by human activities such as road building -has gained a foothold in Nairobi National Park, especially in the Athi Basin area, where a pylon line is currently being constructed….floodwater also spreads the seeds, so we can expect mega-infestation after the current Rains…

DSCF5404

Each single plant is said to be able to produce 25,ooo seeds -if you want to see the end result, look on the verges of the new by-pass from JKIA heading to the Thika Highway: what a mess….

DSCF5405

The experts tell us that this is a plant (it is of the Feverfew family) which poisons its neighbours, including grass & is a major threat to African grassland ecosystems…in Ethiopia (where it first arrived in Famine Relief supplies) it has compromised thousands of acres of rangeland.

Parthenium causes allergic reactions in people & animals, so pull it up with gloves or a handkerchief…..if you see this plant: DESTROY IT!!

DSCF5406

Parthenium is not to be confused with one of our commonest & most widely spread wild flower species Heliotropium (see above)

Consider the lilies of the field….

By Will Knocker:

“And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin:

And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these……..”

So says the Good Book & this year’s rains in Nairobi National Park has brought out the wild flowers in all their glorious profusion:

The ubiquitous Heliotropum, one of the commonest wildflower geni in Kenya:

The word “heliotropium” is the Latin name for an ancient plant which had
the unique habit of turning to face the sun at all times. The plant’s name is
derived from two Greek words: helio, meaning “sun,” and tropos, meaning “turn.”

NAIROBI NATIONAL PARK 29th April 2013

By Brian Finch:

Mike Davidosn, Jennifer O’Duore and myself met at the Main Entrance to
Nairobi National Park at 6.20am, and were through the gate at 6.30am.
There had not been much rain the two previous nights, but over an inch
had fallen three days before, compounding the accessibility problems
in the Park with many areas away from the main roads very sticky and a
few treacherous.
Water levels had subsided, but in the aftermath the Hippo Pools along
the Mbagathi has been destroyed, all the vegetation on the banks
scoured bare and parts of the track fallen into the river, and a new
small island created! Further up the Mbagathi at Leopard Cliffs, all
the riverine vegetation has suffered the same fate.

We set off for KWS Mess Gardens, on the way there were an Emerald
Cuckoo near the Entrance, and a party of Cabanis  (Placid) Greenbuls
on the short road towards the garden. Whilst they are a common species
in the Kisembe Forest, this was the first time I had encountered them
anywhere east of Nagalomon Dam.

The gardens were quiet, although both Green-backed and Wahlberg’s
Honeybirds were vocal, and for the first time in some six months we
did not hear the lone Black-collared Apalis.

Ivory Burning Site did not produce for us, but Nagalomon was
entertaining with the nesting Black-crowned Night Herons busying
themselves, and many sitting tight on their nests. We counted some
sixty birds, but there might have been more. Interestingly quite a few
immature birds are in the colony, although nothing to do with the
current nesting activity. There were three adult African Darters of
which one was a stunning male.

Taking the back road to Hyena Dam, there were a pair of tame Scaly
Francolins on the track, the African Water Rails were in the swamp,
and a pair of Brown Parrots in the fig tree, which seems to be a
favourite place for them. There was not a lot of activity at Hyena
Dam, but an adult male Little Bittern of the African race payesii was
a nice surprise.

The Run-Off from Hyena Dam was quite an active area. Large numbers of
Jackson’s and Red-collared Widowbirds are in large numbers through
much of the grasslands of the Park. The Jackson’s were bouncing and
singing here. Contrastingly, White-winged are only present in numbers
around the Hippo Pool although we had three at Hyena Dam. There were
three Yellow-crowned Bishops displaying in the typha, but on an early
date there were already fifteen Cardinal Queleas, the males in full
breeding dress.

Along the road to cross the Mokoyeti River we found a Common
Whitethroat which was the only palearctic recorded today apart from
three Barn Swallows.

We took the road to Kingfisher Picnic Site, then the southern road
towards Hippo Pools. Along the way we found a Broad-tailed Grassbird
displaying immediately on the eastern side of the Kisembe Bridge,
there was a Bateleur here also. Closer to Leopard Cliffs there were a
pair of Yellow-billed Oxpeckers at what is probably a nest hole in an
Acacia seyal. Also here was an attractive Pangani Longclaw.

Climbing up towards the Hippo Pools Road, a Waterbuck walking towards
us flushed a Dusky Nightjar out of the grass, but at the walk itself
we only had a Grey-headed Kingfisher and the depressing scene of the
habitat destruction.

On the return we had a nice Shelley’s Francolin on the road, several
Long-billed Pipits which are particularly dark at this time of year
and a Long-crested Eagle back near Nagalomon Dam.

Exiting at 6.15pm we found no one at the gate to exit our cards which
is a royal pain in the backside. The Customer Care people shutting up
shop at 6.00pm is far too early with nearly another hour of daylight
left in the day. Hardly a sincere Customer Care at all!

Mammals were few and far between, the best being a Steinbok near the
Kisembe River Bridge. We did not visit the Athi Basin area however,
and quite likely there are still some in that area.

Another great day in the Park, in spite of restrictions necessitated
by the recent weather activities.

 

Birding with Brian Finch 8th April

After a wet night that had turned Langata Road into a flowing river, Mike Davidson, Fleur Ng’Weno, Jennifer Oduore, Karen Plumbe and myself met at the Main Entrance to Nairobi National Park at 6.30am. The overnight rain confined us to the north, as the roads were too muddy and treacherous to venture to the southern portion of the Park. In fact we confined ourself to KWS Mess Gardens, Ivory Burning Site, Hyena Dam from the front road as the back road impassable, Nagalomon Dam, Karen Primary School Dam and Eland Hollow which is a small proportion of the Park. We were out through the Main Entrance at 3.30pm, having recorded nearly 150 species. On the descent road there was a Common Buzzard drying out in the beautiful sunny morning light. Our first call was Nagalomon Dam, this was the first time that I have ever seen it, the drift just before the Causeway was a flowing river but not too deep to negotiate, Nagalomon Dam has lost its reed-bed, there only being a metre wide fringe along the shoreline, and the water level was very high turning the Mokoyeti River into a raging torrent. There were over forty Black-crowned Night-Herons incorporating just slightly fewer immatures sitting in the trees along the bank where they were accompanied by a Great Egret and male and female Darters. In the far corner were a pair of Spotted Thick-knees which had probably been washed out from a normal day roost, and were at the edge of the water. Along the causeway was a Pygmy Kingfisher, which may or may not have been related to a pair at Ivory Burning Site later, and the dam also had a Giant Kingfisher. From here we visited KWS Mess, but it was surprisingly quiet, Scaly Francolins were making a lot of noise, the Black-collared Apalis was also very vocal, there were a couple of Spotted Flycatchers and Garden Warblers but no other palearctics, a pair of Pale Flycatchers were on the front lawn. On exiting through the gate there was a male Crowned Eagle not ten metres from us, and quite indifferent to our presence. It was perched three metres above the ground, and intently scanning the ground below it. We drove past it and away, leaving it still searching the ground. On to Ivory Burning Site, and there was Kilimanjaro with a good blob of snow on the flanks, and crystal clear. An Emerald Cuckoo was singing in the adjacent woodland, Eurasian Bee-eaters were somewhere up there, but could not be seen, a Wahlberg’s Honeybird was in the central Acacia gerardii, which were also attracting warblers. Garden Warblers voices were all through the scrub, large numbers must have been in the Park, but they were the only sylvid recorded, there were quite a few Willow Warblers and more than a couple of Olivaceous Warblers. Also there was a visiting White-browed Sparrow-Weaver and African Firefinches calling from cover. Next we went to Hyena Dam, on the way there were still Whinchats present, and we had four today, another Spotted Flycatcher, the first of twenty-five Red-backed Shrikes, first of ten Lesser Grey Shrikes and all three Widowbirds in full breeding dress. The dam was quiet, with a young Fish Eagle, Yellow-billed Egret and three Wood Sandpipers. The excitement here was when the young Fish Eagle swooped down on a Hadada, and the other Hadadas came in to mob the eagle, but in vain. From here we left for the Main Gate to deposit Fleur, after a pair of Yellow-bellied Waxbills along the road, we then went round to Eland Hollow the long way round. There was a Shelley’s Francolin moving like a chameleon across the road on the way, and a Secretarybird by the road edge, and at the dam was a young male Darter, a pair of Red-billed Teal, a pair of Bateleurs, three Sand Martin with a steady stream of Barn Swallows, and at Karen PS Dam a pair of very still Spotted Thick-knees. Returning to the Main Gate there was an adult Fish Eagle along the Mokoyeti, and amongst a group of Little and Palm Swifts mixed in with Barn, Red-rumped and Lesser Striped Swallows were two birds that resembled Pallid Swifts. It was a very nice day with so much to see and in such crystal clear conditions, and confortable climate. Mammals were obviously further southwards as we did not see too much of interest, the usual Hippos were at Nagalomon and Hyena Dams, and we had a lioness not far from Karen Primary School. On the return we encountered another lioness walking along the road, and followed the animal slowly for about a kilometre not wanting to disturb it by trying to pass it. We were rewarded for this, as in the last half kilometre she starting calling a double grunt, and I thought that there was a likelihood she might be calling cubs. Then two four to five month old cubs emerged from the grass, and just in front of us we witnessed the greeting ceremony, playing, and drinking as a family, out of a road puddle. It was all just so magical, needless to say there was a lot of digitising taking place.

Wildebeest Calving

By Will Knocker:

DSCF5251

The NNP gnus calve in March & this year is no exception..

DSCF5248

Usually they drop their calves in the Sheep & Goat land, but this year they have calved in the Park proper, perhaps owing to lack of grazing outside as a result of a very hot January/February..

DSCF5227

DSCF5224

There are only about one hundred & fifty wildebeest in NNP, so let’s hope it is now that figure + +

DSCF5223

Once one of the most numerous herbivores in the ecosystem, wildebeest numbers are much reduced.

Let’s hope that trend  reverses with these new additions to the population..

Bustards in NNP

By Will Knocker:

DSCF5178

In the current dry spell, bustards are more visible as the long grass dissipates.

NNP is a haven for at least 4 sp. of bustard (see Bustards category on the menu on the left for more stories.)

This is a male White-bellied bustard..

DSCF5182

And the female (White-bellied)….the loud braying ventriloquial calls of this sp. are a typical sound of the plains.

The Last Gnus

By Will Knocker:

DSCF5131

C. t. albojubatus (Eastern White-bearded Wildebeest), of which species the IUCN says: “ However, recent population estimates suggest that the future prospect of some subpopulations or subspecies is of some concern, particularly that of the Eastern White-bearded Wildebeest (which, it seems, may have undergone a precipitous decline in numbers).”

DSCF5133

Hope for the future? A yearling (born March 2012)……

DSCF5134

This species was once one of the most numerous herbivores wandering the vast high plains of the Athi Kapiti Ecosystem of which NNP is the last remaining pristine corner: it has been estimated that there were 100,000 at the beginning of the Twentieth century.

Now: ”Eastern White-bearded Wildebeest, 94,000 (with about two-thirds in and around protected areas)”, of which we in NNP have about one hundred & fifty individuals (144 counted in February game count).

DSCF5168

‘Our’ gnus tend to live on the rapidly dwindling Sheep & Goat Land between the park & the ever-burgeoning New Town of Kitengela south of the Park, which is heavily grazed short-grass plain habitat. The question must be: will they move into the Park once this last stronghold goes the way of the rest of the ecosystem?

The majority of the gnus in the Athi Kapiti live south of the Athi-Namanga highway, which they cannot cross to get to the Park. These will find it difficult to survive in an increasingly humanised & truncated ecosystem .
