First record of the critically endangered sociable lapwing in its former range south Kosti West of the White Nile

A field trip was organized on 3rd December 2012  as  a part of the project to survey waterbirds in Sudan collaboratively between ONSFS , Wildlife Conservation General Administration , Sudanese Wildlife Society and University of Senar . The mission was to cover the former wetlands which surveyed last two years at  Senar and White Nile and to discover new bird important sites as well.
In the way from Khartoum to Senar , we decided to have quick turn to check some wetlands at Butana area which we told about by some former visitors but we found only Hafeers (atificail water harvesting basins) which highly disturbed by pastoralists and their animals and few  bird’s species were seen there such as little grebe, spur-winged plover. Some raptors observed in the way back including lappet-faced vulture, steppe eagle and ruppelle’s vulture

 We spent the night at University of Senar guest house and in the next morning we headed towards the Rahad Canal which was surveyed last year and about 20000 of demoiselle cranes were inhabiting the site . White-tailed lapwing was observed beside the road in small maya(wetland) .The important maya (wetland) covers the area between bridges 45 and 60 (15 km) which contains high numbers of demoiselle crane(4500) , ruff (7000) , northern pintail(50), northern shovellor(500), Eurasian widgeon and some other small waders .

We started counting from the eastern side of the maya  but for hundreds meters only as the area was muddy , so we turned back to the western side and on the way we passed below Dark-chanting goshawk  which stands on top of small tree by the road.
The maya lies in the eastern side of Rahad Canal and only way to count the maya from the western  side by walking the 15 km on foot as the road was too bad to drive cars .The team was divided into tow groups and each one started from the opposite direction and met at the center which means each group walked 7.5 km (long way!!!!!!!!!)  . We spent more than five hours counting birds at this amazing maya which needs to be declared as Important Bird Area (IBA) .

Sennar state contains quite good numbers of mayas(wetlands) with high species richness and abundance either permanent or  temporary and during the survey we covered some of them in the first two days such as Konaf, Elrigaiba, Abu Hujar , Wadd Eljak, Um Laban and Um Kitir.
The amazing thing was the high number of raptors seen soaring there like  short –toed snake eagle , marsh harrier and some kites. After checking some mayas near Damazin –Singa way one day morning  , we decided to stop for breakfast rest under the shaded Balanites aegyptiaca east Alkonaf bridge but when we  approached to the tree , hundreds of roosted carmine bee –eaters came out of the tree and we realized from the signs of their feces on the ground that the tree was used for long time by the bird . I checked the water canal beside the tree where birds flying over the canal to perch on the electric wires on the other site and I continued for some minutes looking for nesting sites may be hide some where on the canal sides as the bird usually nests by digging holes in the cliffs but nothing was there. Also we noticed high numbers of black kites on the other trees but we couldn’t find the reason of their presence beside the Carmine bee-eaters.

Some mayas checked as part of  Blue Nile and inlands mayas namely Elrigaiba, Elshamia  and wadd Eljack which inhabited by some wader dominant by ruffs, black-winged stilt ,cattle egret and little grebe.

On 6th December , we headed towards Sinar Dam to take the way to other areas further south in the White Nile State and we counted waterbirds in the wetlands we passed through  in our way . Some points were selected to count waterbirds in the Blue Nile as samples for the River before arriving at the Dam where quite good number of species seen there mainly cormorants, herons, ducks ( gargany, pintail,wigeon) , egrets, thicknee and terns

Hence, we took our way directly towards White Nile and spent an hour at Wildlife Administration to pick a guide who knows the area very well and to save time in searching for mayas. In the beginning , our plan was to check mayas in our way to Um Jar which is our main target and after some hours driving in sandy clay lands with small shrubs , trees and mainly dominant by grasses give fascinating landscape which I never thought it will be like this, we arrived at the first maya called Alshwaf  holding small water body rich and about 16 species were seen there mainly waders and few waterfowl. At this time ,it was already became dark with the sunset but far west we saw large flocks waving in the air against the red light of sunset  . We continued our way to Um Jar to spend the night there and next morning to count Um Jar according to our previous plan but the image of the large flock was still brightening in our head especially Pierre (ONCFS) when he insisted to go back next morning to the same place as they already have an idea about Um Jar and waterbirds there. The team stayed conscious to late evening waiting grilled goat meat prepared by our host and it was unusual for foreigners to have dinner at 12:00 am but it was a nice meal.
Next morning , while we were going back to the same place on 7th December , we stopped at  Algardood maya just beside the road with fascinating nature comprising from merged tall grasses and reeds which is ideal habitat for waterbirds prefer hiding and walking on floating plants . We recorded about 500 squacco heron, 50 long-tailed cormorant , 10 African jacana  , 10 pied kingfisher , 20 whiskered tern beside some other species.

The big surprise was waiting us when we reached the place where we saw the large flock last day and astonished by  the huge numbers of ducks living in small clear maya  called Alsilaiaa which is not far from small village there. Unbelievable, about  40,000 ducks dominant by garganey (17,100)   , Northern Pintail (15,700) Eurasian Widgeon (4900) , Northern shovellor  (2100)  and small numbers of Fulvous whistling Duck, Comb Duck, Ferruginous Duck and common teal  beside some waders in the shore such as ruff, demoiselle crane, abdem’s stork and amazing Ruddy –Turnstone which is only known to be in the Red Sea coast.
Flock of Ducks- 7/12/2012  White Nile
 
We covered one maya more with considerable species richness called Um Suar  before we took rest for breakfast at midd-day .In the first maya we recorded more than 300 black-winged stilt,  124 black-tailed godwit , 700 ruff, 140 little egret , 40 little stint, 30 grey heron, 31 glossy ibis with only two waterfowl (garganey &fulvous duck) which deserved to called wader’s maya and it lies just 10 meters in front of the a village and we wonder how the birds live near the village but later we knew that people there don’t hunt birds and they believed that  bird meat makes kind of skin irritation and we found ourselves happy with this belief for bird welfare.
Good news comes together,  while the team waiting for the breakfast  , small group decided to have quick look at two mayas near by which called Um Sila and Um Suar 2 as it has the same name like the previous one .UM Sila is a deep maya lies in the main stream of Khor Ubu Habel which extends from western Sudan to far east supported all mayas in its way and this year the water level was high and the Khor flooded all over the area filling the depressions and reached area not filled for some years. More than 150 long-tailed cormorant were there. When we stopped at Um Suar maya , I pointed my telescope to far east end leaving the near species for those who have binoculars to count and I started to count birds with good start of Eurasian Curlew (not its range) and just left I couldn’t believe my eyes with the presence of two individuals of critically endangered sociable lapwing taking bath with their remarkable black spot on the tail , I shouted for colleagues to check more and all wondered. It is the first record of sociable lapwing in its former range south of Khartoum west of the Nile for long decades. The Sudanese Wildlife Society has a project for this species in collaboration with RSPB since 2008 following two groups tagged with transmitters wintering in Sudan but never recorded south Khartoum and it moves between east and north Sudan. This gives us an idea about its range and what areas we should cover next time. The bird was seen associated with the Eurasian curlew, gull billed tern , black-winged stilt, little stint and common ringed plover. Pierre took pictures of the bird but in low quality because of the far distance .

Each maya seems to have its own characteristics and waterbirds’ species as in the next maya (Alsunta) we recorded 400 glossy ibis, 590 black-winged stilt but the ruff look common every where. Before it gets dark, we headed towards Tendalty town to spend a night there and to survey some wetlands there but we don’t know where we can get place to sleep. Our destiny took us near his door as we stop to ask some guys if there is guest house and they guided us to the next door where there is a hospitable man always opened his house to guests . For tow nights he stood himself to serve us beside ordering our dinner from his own pocket ,so thanks Mohammed Hassan for your hospitality

  Next day on 8th December , we went to Tendalty Dam which built on Khar Ubu Habel to harvest water during flooding time and both sides of the Dam covered by acacia nilotica due to its water resistance. About 18 species of waterbirds observed there mainly white-faced duck (730), little egret, little stint but others in low numbers and it is not as we thought but may be due to disturbance from people moving every where .

Our permission for movement was up to White Nile and not included North Kordofan State ,so we get back to continue surveying mayas near Khor Abu Habel such as Wadd Alayis, Um Oud , Alsunta, Alawama, Abu Gunbary  and Saggay Elfadil . large number of waterbirds were seen there and the team  felt exhausted from counting birds all the day with no rest.  Waterbird species at these mayas according to highest numbers were ; ruff , black-winged stilt,  little stint,  glossy ibis, little egret, great white egret and spur-winged plover respectively. At night we get back to Tendalty to spend our last night there and next day we tried to cover the rest of mayas (wetlands) but their numbers were more than our few days there as the water scattered in wide areas.  These wetlands need more than one week to be covered in proper way .

Morning visit to Elhalfaya Bridge Area

I am happy to add a new post and apologies for absence since end of last September due to my travel to Tanzania to participate in the 13th Pan-African Ornithological Congress , the most excited ornithological congress I ever attended with participation of more than 200 ornithologist from world wide countries who did researches in Africa .The conference held every four years (www.paoc-africa.org) and next time hope to see many Sudanese Ornithologists there. After that I spent some days in my village Diem Elgarray for Eid vacation.
In early morning 15/11/2012 I headed towards the agricultural farms around Elhalfaya bridge which is not too far from my house in Eldroshab looking for some migratory species as the time for fall migration had been already began with winter onset. The area is mainly agricultural lands which all covered with water during flooding time adding new fertile soil to the land used by farmers to grow some different crops and vegetables.  
My first sight was two common kestrels soaring above the trees with black kite and some passerines perching on the electric wires such as desert wheatear, village indigo bird and African silverbill. My not professional camera makes it difficult for me to have good clear pictures of birds especially those moved very quickly and I realized that birding need equipped birder.

I continued walking down to water stream blocking my way to the Nile where there were few waterbirds such as Egyptian plover and spur-winged lapwing. I forced to change my way and headed towards the bridge to cross to the other side and in my way I saw group of common bulbul , white-headed babbler , red-billed firefinch  while house sparrows , mourning dove and laughing dove every where constitute the abundant species

When I reached the bridge , I noticed some waterbirds  such as the local nomad kittlitz’s plover and the palearcitic migrant little stint . Also group of egrets probing the mud for food mainly great white egret and little egret. The shaded area under the bridge provided suitable roosting site for Ethiopian swallows flying there and sometimes perched on the electric wires

 Then, I climbed the bridge to cross the small khor and left again the bridge to walk through the farm while the Nile still far west and only few species were seen included African silverbill, yellow wagtail, common bulbul and masked shrike . Old unoccupied weaver colony on acacia nilitica tree was observed and some house sparrows moved between the nests

The Nile shores were not as I expected regarding to the number of species and habitat composition too. The shore in the southern side of the bridge was sandy cliff with no space for waterbirds as the water was deep . the sandy cliff extended  two hundred meters north the bridge where I saw some Ethiopian swallows roosting there and on the way north I saw two little bee-eater on the small shrub and pied king fisher

Hundreds eggs of Egyptian Goose has been eaten by one fisherman at Nuba Lake

You can’t imagine how human behaviour can be destructive unless you faced with one of these destructive behaviour . During the period  from 23rd March  to 4th April 2011  we ( Esmat , Nasir , Mohanad  ,  Officer Suliman Hakim and his soldiers )  were surveying Nuba lake in Northern State in the border with Egypt  to assist our colleague  Ismail  in his Nile Crocodile study . The survey success depends mainly on our local guides Ali Balla (expert in crocodile behaviour and distribution) and lovely Ahmed Ibrahim( boatman).  
During our normal survey, we stopped at small island to monitor crocodiles from that Island. We found about 10 nests of Egyptian goose but only two of them had eggs (11 and 14 eggs in each) and we thought for the first time that the empty nests may hatched but no broken egg shell remained near the site

 While we were talking, a fisherman stopped by the island with his boat and we noticed that he had dozen of geese eggs in his scarf and immediately the mystery resolved. He knew very well the site and the rest of eggs in the two remains nests but he didn’t know that we are conservationists as he offered us to take some eggs

The big surprise waiting us when we arrived his camp on an island just about 100 meter from our island. We shocked by the hundreds broken eggs around the camp and 25% had dead embryos. He simply explained that ‘ I felt boring from eating fish ,so I decided to change to bird’s eggs’. We clearly noticed that he didn’t collect  these eggs from one site due to the large numbers of broken eggs and when he stopped at the island ,he was already carried some eggs.
He claimed that he didn’t know it is prohibited . At this point we felt guilty too as we didn’t have awareness programmes for them inspite the importance of the lake for migratory birds and crocodiles as well

 The Nuba lake is very wide with many islands scattered in the whole lake which used by birds and crocodiles for nesting. The eastern side of the lake is mountainous   while the wastern side mainly sandy with small hills. Species seen there were great white pelican, spur-winged plover  , little egret, African skimmer , Nile Valley sunbird , white-crowned wheatear, European turtle, whiskered tern, white-winged tern, squacco heron, mourning dove, laughing dove, lesser black-backed gull, grey heron  etc.........

Dinder National Park(DNP) ..dry season 2011

Team of researchers (Esmat -Nasir- Mubarak- Gamar) from Wildlife Research Center made birding expedition to Dinder National Park during the dry season between 18th – 28th April 2011 . We arrived late at Galagu Camp (the main camp in the Park)  in the core zone where most of animals are congregated due to food and water abundance and the conservation measures. Group of passerines moving around Galagu Camp  near small water spots coming from tap water or waste water from the natural refrigerator (simple costruction using natural air for cooling). Group of cut-throated firefinch, African silverbill moving between water hole and trees branches as well as  wattled Starling, red-cheeked Cordonbleu and Greater blue-eared Starling.

Pair of  Red-throated Bee –eater were seen on top branches of  green tree near the edge of Khor Galagu (stream)  beside  two little Bee-eater on the lower branches. On the opposite site of Khor Galagu there was a group of endangered Hooded Vulture roosting on Dom tree which always found in the riverine area

  Through our birding, noticed that most of the mayas (wetlands) were dry out as we were in late summer and a few mayas were deep enough to hold water for long time such as Ras Amir and Birkat Eltamaseeh. Firstly we headed to Abdel Ghani maya which is about 1 km away from the Galagu camp and it seems dry out expect small water hole pumped  from anew underground well. Small group of birds gathering around the water all the time as the weather is very hot during that time of a year. European turtle Dove with mourning and laughing doves were seen  beside the migratory wood sandpiper, black-headed heron and open bill stork . many migratory species were seen during non-migration season living in the Park making understanding migration confused unless we have sustainable ringing and telemetry . Small group of woolly necked stork and cattle egret were feeding in the driest part of the maya . Hundreds of tufted guinea fowl hiding under the shade of big trees at maya’ edges .

Our next direction was Ras Amir maya (lake) which is 14 km from Galagu camp and is the largest and deepest  maya in the park . Most of our birding concentrated in this maya due to the largest number of birds and species richness. On the way to Ras Amir , a female Ostrich with chicks running in front of our car  on the road  while the male was running in the opposite side trying to drive us away from them.

Most the birds were congregated at south edges of the maya where short grasses and floated plants covering the water    surface. About 500 spur-winged goose , 200 white-faced whistling duck , 100 African Jacana while 100 grass hopper Buzzard soaring above.  African jacana preferred this maya due to the presence of floating plant which make it easy for the jacana to walk on the water using her long toes for balance.Also cattle egrets, open bill storks , black –winged stilts , mourning doves, northern masked weavers , laughing doves and spur-winged plover were there.

 By the end of the day,  we erected numbers of  mist nets to catch some birds during the night for ringing . The catching started directly after sunset by chasing birds towards the nets .  We caught some waterbirds and we ringed only migratory species as we have limited number of  rings .Species captured were pied King Fisher,  greater painted snipe and wood sandpiper .We did this two times chasing birds but after three hours the Park was completely dark  and our ranger started complaining as he is responsible for our safety and we started listening predators voices become more nearer ,then we decided to leave but  nets were left opened for the whole night.

We woke up early next  morning to check our nets and to release birds as early as possible  . Two nets were come down to the mud with heavy immature African Fish Eagle tangling in the net and it may be struggled for some time . We released the bird from the net and kept it for  a period of time to make sure he can fly well. Capturing is not hindered by predators but also the large number of bats caught in the net and leaving the nets with big holes .  Marabou storks were also slowly walking on the dry area near the fishermen camp searching for fish scraps.

 We spent two days at Ras Amir then we headed next morning towards the western side of Dinder River . We stopped at Birkat Eltamaseeh which lies in the Dinder River bed near the main road crossing he sand ground of the river by spreading sorghum stems above the sand to prevent cars from being stuck in the sand.  Remarkable hamerkops were seen on the pond’s shores  with great white egret , spur-winged plover , Senegal thicknee, long –crested eagle and open bill storks. Pair of African fish eagle looking at water body from top branches of a big tree beside the pond.  Large number of animals depending on this pond as water source in this site (preys and predators)

Our next travel to Semaaya maya  far from the center in the wastern side of Dinder River but the maya  was dry out except small muddy area rich with fish . Fish eating birds were aggregated a round the mud such as herons , storks, pelicans . Hundred of snares were found left by the fishermen which make major threats to waterbirds probing in the mudd

On the driest part of the maya at 11 am when the sun started to become more hot , we saw varied species sharing the narrow shade by the end of the maya . The group includes saddle- billed stork, woolly necked stork, cattle egret, black-headed Heron and truly migrant white stork. Group of ostrich also observed moving around.
