Birding
in Ruaha National Park is extremely interesting and rewarding.
Ruaha is located in south-central Tanzania, a location that until
recently has been difficult and expensive to get to. Due to its
vast size, thanks to a massive extension to incorporate the Usangu
wetlands, Ruaha has doubled from 10,200 to 20,220 sq.km. In addition
to this, Ruaha is fortunate to be surrounded almost 360 degrees,
by Game Reserves, plus west of these Reserves are yet more Forest
Reserves, so the whole ecosystem, is a vast, virtually untouched,
wilderness area of more than 45,000 sq. km.
The
remote areas are difficult to access particularly during the wet
season, therefore, little “serious” birding has been
done in these seldom visited places. Rob and I are both artists,
Rob a sculptor and I am a painter, and in our spare time we are
avid birders. We have been extremely privileged to have lived
in Ruaha National Park for 17 years, during that time Rob compiled
the official, Annotated Park Bird List, which now stands at 572
species. We have managed to pull up some very interesting records,
two of them new species.
We first came to live in Ruaha National Park in June 1994. It
was about a year after this that I decided to do a large water-colour
painting of the Red-billed Hornbills that were so plentiful in
the Park. I always work from life, so I set off one morning in
search of these beautifully patterned birds, hoping to find some
willing to pose for me for more than a few seconds! Sure enough,
they were everywhere, and I stopped often to look carefully at
the facial details, as this is always the most important part
one needs to “get right”. I became rather bemused
as all the birds I stopped to look at had black grubby faces,
and pale eyes, nothing like the cleaner looking Red-billed hornbills
I had painted in Tarangire National Park, in northern Tanzania.
Those had pink skin, dark eyes and plenty of white on the face.

At
that time I was very much a “novice” birder, I thought
them to be young birds, so I decided to continue looking for the
appropriate subject. Over the course of several days I never found
what I was looking for, absolutely all the Hornbills I had observed
over more than 600 sq km had black faces and pale eyes. On my
return to camp I mentioned to Rob that there was something funny
about the Hornbills here. “ Oh nonsense” he replied,
“these are all Red-billed Hornbills”. To cut a long
story short, it didn’t take Rob long to agree with me. There
was something different about the Hornbills in Ruaha. In the 1960s
and early 1970s.
The
photo clearly shows the black orbital skin and the pale eye, diagnostic
for the Ruaha Hornbill.
Rob
did extensive collecting for various American museums, of birds,
small mammals and bats all over Africa, so he was very familiar
with the scientific side of birding. Thus, he began the process
of collecting DNA samples, documenting the differences of our
bird, and sent the whole lot down to Alan Kemp in South Africa.
Alan, was by chance at that time, reviewing all the African Hornbills.
In due course, we were told that the DNA was indeed different,
and that this was a “new species”. We, and the Park
officials were thrilled and it was duly called, Tockus ruahae,
the Ruaha Red-billed Hornbill. The extent and range of these birds
is clearly indicated on the map, which was kindly supplied by
Neil and Liz Baker, from their Tanzania Bird Atlas. (In Sinclair
and Ryan, Birds of Africa, South of the Sahara, Second Edition,
2010, this bird has been erroneously named Tanzania Red-billed
Hornbill, instead of the published name, Ruaha Red-billed Hornbill.)
Shortly
after the excitement of this had died down, Rob and I were enjoying
a trip in a remote and unexplored, relic, highland forest, in
the extreme western portion of the Ruaha Park. At 1,800 m this
small forested area has proved to be most interesting for birds,
which is another story altogether! However, in 2002, just as we
were leaving this highland forest, to head back home to the lower
Ruaha Valley, I spied a black and white bird that was hopping
around, it looked similar to Arnots White-headed Black Chat, (Pentholaea
arnotti), but this bird had a black cap and a complete white
collar, encircling the neck. It flew off, and I couldn't locate
it again to show Rob, I was very excited about my find, but we
had to leave. So it would have to wait until we returned the following
dry season.
In
2003, we returned, and set up our camp in a slightly different
location. We were surprised and thrilled to find that we were
right next to a nest that belonged to the black and white bird
with the cap and collar that I had seen the previous trip. We
were traveling with the Chief Park Warden, Mr Mtahiko and the
chief ecologist, Gladis Ng’umbe, so we got the go-ahead
to collect DNA samples. We also took loads of photos, and I did
several paintings too. We all became very fond of this brave little
bird who hopped around so happily, totally unfazed about us camping
in her space. The nest was in a hole at the top of a 4 ft stump,
which was located right amongst a busy area of camp activities,
so we had fabulous viewing of our new bird! Again, Rob took charge
of the scientific side of things and sent all our information
to Dr. Rauri Bowie, in South Africa. Rauri was meticulous with
his investigations and left no stone unturned, so we were kept
on our toes. We travelled extensively in western Tanzania, looking
to see the extent of this bird. We also had the support of Neil
and Liz Baker, who are currently working on the Bird Atlas of
Tanzania, and their support group added to the sightings. In the
end, we found that its range began west of the Eastern Arc Mountains,
south into Zambia and as far west as eastern Congo and Rwanda.
Interestingly,
the Eastern Arc Mountains provide the boundary between the Ruaha
Chat and the nominate, Arnots White-headed Black Chat, east of
these mountains you will only find Arnots White-headed Black Chat.
Information was flying backwards and forwards by email and phone
calls to Rauri, who had then moved to Berkeley University, California,
to take up a professorship, lecturing in ornithology. Between
us, we continued to compile more and more information. Finally,
some 7 and a half years after I first saw our “new”
Chat, the paper has been accepted and we have yet another “new”
species. They have been called Pentholaea collaris, or the Ruaha
Chat. The difference between this new bird and the Arnots white
headed black chat is in the plumage of the female. The male however,
is identical to Arnots Whiteheaded Black Chat. (If anyone is looking
up this bird in the second edition (2010) of Ryan and Sinclair's
Birds of Africa, South of the Sahara, please note the Latin name
therein is incorrect, also the picture depicts the plumage of
a young female, who has not yet matured into the diagnostic, full
white collar encircling the neck).
We
would like to thank all the people who helped us on this journey
of discovery, most of all we would like to thank the then, Chief
Park Warden of Ruaha, Mr Mtahiko, who’s enthusiasm and co-operation
never wavered, plus Godwell Meing’ataki the Chief Park Ecologist
and current acting Warden in Charge for his invaluable help. Dr.
Rauri Bowie was fantastic, and we are really indebted to his hard
work and enthusiasm for the project. We were delighted when after
8 years of knowing Rauri only through emails, we were able to
meet face to face. We enjoyed very much having dinner together
in our nearest town, Iringa. Needless to say, we had an awful
lot to “chat” about! The circle is now complete, but
whose to say there aren’t more surprises in store!
In
the western miombo area of Ruaha, we have noticed other exciting
differences which may represent new species. A Weaver, a Tit,
and seemingly a variation of the norm, in the Greencapped Eromomela.
We are confident that the White-tailed cisticola yet to be named
from Kilombero, in SE Tanzania, is also found here in isolated
marsh situations. Further more, a Crested Guineafowl in Ruaha,
which was originally thought to be Guttera p pucherani,
but on our investigation, transpires to be the same as the original
Guttera pucherani granti, named from one specimen collected
from Dodoma, in 1871 (Elliot ), to the north of Ruaha. Mysteriously
this race was dropped from all literature. This bird sports red
on the face, and red under the chin with a broad, plain black
collar. However, after our investigations, we found that this
bird is certainly much more widespread than previously thought
and is now known from Lake Manyara in the north, the Harar Hills
and Bwi Hills (Pienaar Heights) between Babati and Kondoa, Ruaha
National Park, the areas south of Ruaha, the Udzungwa National
Park, and Mikumi National Park. We are, together with Don Turner,
in the process of reinstating this bird to its original name.
Ruaha
lies on the convergence zone of northern and southern flora and
fauna, hence we have a wide and unusual variety of plants and
animals. It follows then, that the birds should be as equally
diverse and interesting.
The
recent expansion of Ruaha, comprises the Usangu plains and wetland.
This is a fabulous new resource for the Park, encompassing a very
large wetland area which is home to a vast array of waterbirds.
During the breeding season thousands arrive here to breed and
it is spectacular. The most exciting species in this location
is the Wattled crane. The wetland is a fabulous compliment to
the rest of Ruaha.
It
is a fascinating place to live, every day presents new excitements
great and small. I keep detailed records of the birds, animals,
weather and the vegetation, which are invaluable. Everyday we
learn new things about our fabulous environment and how the birds,
animals, trees, flowers, sunshine, rainfall, insects, etc. all
depend on what everything else is doing, or not doing. Nothing
can stand alone and nothing can be isolated from the whole. In
short the “big picture” is all important.
We
are extremely privileged to be living in this Paradise. We would
like to take this opportunity to thank Tanzania National Parks
for their help and support, and to congratulate them on the excellent
way they manage their Parks.
General
Information Whilst birding is good at all times the inclusion
of migrant species would be from September to late May.
There
is only one rainy season, generally it begins in December and
ends late March or mid April. During the rains the Park is very
lush and green, with wonderful flowers and breeding birds, the
Ruaha River looks superb too. In my view, April through to the
end of June is an extremely beautiful time of year, especially
for flowers and trees, though game viewing is not as rewarding
as it is later in the dry season. From end of July the vegetation
begins to dry, by September it looks very grey with little greenery,
these drier months are however, a great time for game viewing.
October and November tend to be very dry, and hot, but at all
times Ruaha holds its own charm, and every season has its own
particular magic. Most areas of the Park are accessible all year
round, however, some of the more remote Miombo areas are difficult
during the rainy season but are accessible from July to December.
