White-winged Cliff-Chat Myrmecocichla semirufa, one of the
endemics
Ethiopia is rich in birds. Of ca. 1850 species found in Africa, a little less
than 850 are recorded from Ethiopia, together with Eritrea. Although Tigray
only covers 1/15 of the area of these two countries approximately 500 bird
species can be seen here! It is not a coincidence that Tigray is rich in birds.
The variety in habitats over a vast altitude range is large. Though there are
birds that can be found almost everywhere, many bird species are adapted to
live in different environments with their own specific geographical features
and subsequently specific flora and fauna.
Western Tigray bordering Sudan is situated below 1000 m. Here birds belonging
to the Sudan-Guinea savannah biome can be found. This is the vast area ranging
from West Africa up to the Ethiopian highlands. The Ethiopian highlands form an
"island" with a relatively cool climate, compared with the surrounding hot
areas, and have a totally different and unique montane bird life. On this
isolated island a good number of species developed that are found nowhere else
(the endemics). In Tigray the highlands rise up to over 3000 m with the highest
peak of almost 4000 m. East of the highlands today's Tigray extends a little
into the Danakil depression with some plains situated below 1500 m. Here a
number of species is found inhabiting the Somali-Masai savannah, the lowlands
East of the mountain massifs in Ethiopia and Kenya/Uganda.
The Tigrayan highlands are not very wide, because the Tacazze river, one of the
tributaries of the Nile, draining the major part of the Tigrayan highlands,
separates them from the Semien mountains, west of it. Through the river valley
and adjacent hills birds typical for the Sudan-Guinea biome can penetrate far
into the highlands where they sometimes can be seen alongside birds typical for
the Somali-Masai biome, that enter the highlands from the East. For instance
White-fronted Black Chats Myrmecocichla albifrons and Chestnut-crowned
Sparrow Weavers Plocepasser superciliosus together with
Brown-tailed Rock Chats Cercomela scotocerca and Rüppell's Weavers Ploceus
galbula
. Although there are many more interesting aspects about the savannah birds of
these two biomes, for the visitor to Tigray the highlands probably have the
most interesting habitats and avifauna.
At the many steep escarpments with often breathtaking views of cliffs hundreds
of meters high and at the river valleys cut deep into the cliffs, we can find
some of the endemic bird species of Ethiopia together with Eritrea (also in the
following text "endemics" refer to Ethiopia and Eritrea!). The melodious
whistles of the White-billed Starling Onychognathus albirostris, a
rather long-tailed blackish bird with reddish wing panels, immediately attract
attention. Less conspicuous is the Rüppell's Chat Myrmecocichla melaena
, a totally black bird with clear white wing panels, very little known in its
habits. A third endemic here is the White-collared Pigeon, the grey pigeon with
white collar and wing patches.
In Tigray not much forest is left. Erosion, caused by woodcutting, overgrazing
and droughts, being the most important environmental problem of the region. But
there are still good forests on eastern escarpment. In the southern parts we
find the Abyssinian Catbird. It is one of the northernmost places where this
mysterious bird of thick cover with its beautiful song can be found. Scientist
still do not know to what other birds it is mostly related.

Other often very fine pieces of woodland exist around the numerous springs
everywhere in the highlands. These areas are very rich in birds, such as the
quite colourfull Rüppell's Robin Chat Cossypha semirufa that mostly
keeps hidden under the thick cover, the Tropical Boubou Laniarius aethiopicus,
of which duetting couples make a nice bell ringing sound, and the Verreaux's
Eagle Owl Bubo lacteus, the huge owl with it's strange pink eyelids,
that prefers conifers as hiding place. Here we also find other endemics, like
the Black-headed Forest Oriole Oriolus monacha, the black and yellow
look-alike of the much more widespread Black-headed Oriole Oriolus
larvatus. Often this bird is firstly detected by its musical call. Fig
trees with it is fleshy fruits attract many other birds, f.i. the near endemic
White-cheeked Tauraco Tauraco leucotis, a brilliant blue and greenish
bird with flashing crimson-red wings, Bruce's Green Pigeon Treron waalia,
with it's strange not pigeon like call, Black-billed Barbet Lybius guifsobalito,
Hemprich's Hornbills Tockus hemprichii, a Hornbill that nests in cracks
in the cliffs and another endemic, the Black-winged Love Bird Agapornis taranta,
a little green parrot, with a rosy bill and, as the name indicates, black
wings. This bird very noisy is much more easy to see than the oriole. Very
rarely also the endemic Yellow-fronted Parrot Poicephalus flavifrons
is seen in Tigray. If Fig trees are standing more solitary in open field also
the huge, turkey like Abyssinian Ground Hornbill will fly into the trees to get
their share of the fruits.
Apart from some permanent rivers and many reservoirs, in Tigray only one natural
lake exists: Ashenge, situated at 2400 m. In the period October-March the lake
holds an interesting variety of Eurasian and African birds. Up to 15.000 water
birds in 47 different species were recently counted in Dec. Bird watchers
visiting Tigrai this time of year should not forget to bring their
identification guides of European and Asian birds, because a total of over 100
migratory species are known. Of the many ducks, Northern Shovelers Anas clypeata,
Pintails Anas acuta and Wigeon Anas penelope can be seen together
with African Pochards Netta erythophthalma, Maccoa ducks Oxyura maccoa
and Egyptian Geese Alopochen aegyptiaca. Furthermore different species
of Grebes, Herons, Ibises, Shorebirds a.s.o. are present. Many birds of prey
roam the shores, among them Long-legged Buzzards Buteo rufinus, Steppe
eagles Aquila nipalensis and Pallid Harriers Circus macrourus from
Asia. Around the lake again some endemics can be seen. Of course, the Wattled
Ibis Bostrychia carunculata that is common everywhere in the wet areas
in the highlands. Where there is some higher vegetation on the shores Rouget's
Rail Rougetius rougetii is living. A not shy large reddish-brown Rail,
that is considered endangered in its existence. In the meadows around the lake
we find a lot of little songbirds, both of Eurasian and African origin. Among
them the endemic Black-headed Siskin Serinus nigriceps and the eurasian
Red-throated Pipit Anthus cervinus and large flocks of Yellow Wagtails Motacilla
flava
that accompany the hundreds of cattle grazing here, to feed on the insects
chased away by them.
Not only eurasian migratory birds can be seen in Tigray. There are also
in-African migrants. Many species are nesting and raising their young in the
season that there is abundance of food. For insect eaters this mostly is the
rain season, in Tigray this is June up to September. Outside this season they
migrate to the southern hemisphere. Some examples are the Abdim's Stork Ciconia
abdimii, that is nesting even in the city center of Makele, some
Swallows and the Paradise Flycatcher Tersiphone viridis, of which the
males have unusual long, white (normally chestnut) tail streamers (up to 2
times there body length). The small, crested Wahlberg's Eagle Aquila wahlbergi
is probably spending its non-breeding season in Tigray.
In this few pages, of course it is impossible to give a thorough description of
the birds of Tigray. But it goes without saying that Tigray is a bird watchers
paradise!
