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.........

 I always (Esmat) carry my mist net with me in my traveling incase we find suitable place for capturing birds for identification and ringing. We erected two mist nets beside bush area and small hill where many small birds flying. Some species captured such as Nile valley sunbird and lesser whitethroat

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)

 Small water body remains at Gererissa maya supported by pumped water to keep animal in that side a live or to avoid animal traveling long distance and competing in specific area but a few species of birds were observed there such as black-headed Heron, pied crow, long-tailed starling , little egret, mourning dove and greater blue eared starling with warthog wallowing in the mud as he always did

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.
