My visit had three main objectives. I participated as a trainer in a Waterbird and Wetland course for wildlife personnel from the Ministry of Environment, Wildlife Conservation & Tourism (MEWT). I was also a representatvie for the Working Group International Waterbird and Wetland Research (WIWO) in talks about long term cooperation on wetland inventory and waterbird monitoring initiatives. These activities were organised and funded by Wetlands International (WI). In addition I conducted a privately funded exploration of several wetlands in Lakes State with the following objectives: - to search for and photograph Shoebill Stork Balaeniceps rex - to photograph other waterbirds and wetlands - to assess the numbers of waterbirds in some of the wetlands - to explore the possibilities for waterbird monitoring - to look for potential sites for field sampling of Avian Influenza in wild birds This report will cover the exploration. Acknowledgements This exploration was carried out with the authorisation and cooperation of the Ministry of Environment, Wildlife Conservation and Tourism, Government of Southern Sudan. I would like to thank Under-Secretary Major General Alfred Akwoch Omoli and Senior Advisor Perez Malande Olindo for their authorisation, support and advise. Thanks also to all other people at the MEWT for their support. I thank the board of WIWO for their moral support. Furthermore I would like to thank Chief Park Warden of Shambe NP Gabriel Gurgury for his guidance and advise in the field. I would like to thank Minasona Peter Lero, for helping in preparation, giving advise and hospitality. Lastly, I am grateful to Wetlands International, in particular Tim Dodman, Oliver Nasirwa, Ward Hagemeijer and Szabolcs Nagy, for their support in preparations and/or company during the WI- mission, which made the exploration possible. 1 Itinerary February 25-28 Preparing for journey.

Figure 2: Map of the exploration area. 3 Results Logistics Organising an expedition in remote areas of Southern Sudan is not easy, as can be expected in a country that has suffered from more than 30 years of civil war and under-development. Several difficulties have been encountered during the (preparation of the) exploration of the wetlands in Lakes State. Organising transport at an affordable rate is difficult. Car rental companies in Juba are reluctant in providing cars (4x4) for use outside the Juba region. If they are willing, prices vary between $300 and $350 a day including driver and fuel. Flying to Rumbek was in this case a better option as prices seem to be lower. However, the number of companies is also less, restricting the choice. Navigation using solely the geographical knowledge of local people can prove to be very difficult. On two occasions, one on foot and another by car, the destination could not be reached. This was due to insufficient knowledge of the accompanying people on navigation, distance or road conditions. This was the case when hiking to a wetland northwest of Pagarau (Annex 1, Shoebill Stork observation). After a long hike, no large wetland was found, only some small ones and access to wetlands was blocked by broad fringes of reed and papyrus. The second case considered a trip with the car to Lake Nyubor (Annex 1), which ended in the bush where the road had virtually disappeared. The road from Rumbek to Yirol was fairly good. The road from Yirol to several kilometers after Yang was good. On the remaining part to Shambe, road upgrading was in process and the road was poor. Availability of motorboats to navigate the lakes and channels of the Sudd near Shambe was very restricted. Outboard motors need petrol, which can pose another obstacle as the availability of petrol can be very restricted, resulting in very high prices. Outside the Sudd and the Nile motorboats are probably non- existent and one is dependant on tree canoes. Shoebill Stork Two Shoebill Storks were observed, one at Lake Yirol and one northwest of Pagarau (Figure 2). Both birds were feeding in shallow 20-70cm deep water covered (50-90%) by floating grass. On one occasion a Shoebill had caught a large fish (60 cm) of a catfish-like species. I was able to get good images of the first bird, which was quite tame. Unfortunately Lake Nyubor could not be visited as this is a potential site for Shoebill (pers. comm. Gurgury). Photography In addition to Shoebill Stork, other waterbird species as well as landscapes and human activity were photographed. It was noted that most waterbirds tolerated human presence and were approachable to relatively close distances. This might reflect a low hunting pressure on these species. 4 Numbers of waterbirds At three sites I conducted a waterbird census with assistance of wildlife officers from the MEWT. The results can be found in annex 3 and 4. The results are preliminary as only fractions of sites could be visited and in some occasions only estimates of the numbers of waterbirds could be generated. The results were communicated to the database of the African Waterbird Census in Dakar. At Lake Yirol thousands of Long-tailed Cormorants Phalacrocorax africanus and several species of egret egretta were seen flying to their roosts. The roosting site consisted of bushes standing at the edge of the water or in the water at the eastern edge of the lake. At Shambe, no big concentrations of birds were found on the lake (annex 4). The largest concentrations were observed on the dry parts bordering the lake and marshes (i.e. Collared Pratincole Glareola pratincola ) and on floating islands of vegetation and mud (i.e. African Skimmer Rynchops flavirostris ). In the dense marsh vegetation (Papyrus, reed, cat tail) no concentrations of waterbirds were found. However, there seems to be an even and constant distribution of herons and African Jacana Actophilornis africana in the marsh, feeding along the edges of pools and streams. For the whole Sudd this would result in high numbers for i.e. Purple Heron Ardea purpurea , Grey Heron Ardea cinerea and Goliath Heron Ardea goliath and African Jacana, considering the surface of these marsh vegetations (Howell et al . 1988; Nikolaus 1989). Waterbird Monitoring The exploration gave a first impression of the Yirol-Pagarau and Shambe (Sudd) areas from the ground. In an earlier stage, a reconnaissance flight had been carried out over the southern half of the Sudd area (in cooperation with the Wildlife Conservation Society). Together with the experience gained from the preliminary censuses, this provides a rough idea of how to organise future waterbird monitoring. As expected, the densities of waterbirds in the Sudd vary greatly between different vegetation zones. Moreover, small waterbirds (ducks, small herons, rails, waders) were recorded during the ground census, which had been missed during aerial surveys. The extent to which areas outside the Sudd contain water varies greatly between seasons. This exploration took place in the dry season, resulting in the water being restricted to lakes, permanent streams and pools in floodplains. This made access to the wet areas more complicated as infrastructure was in a poor state and knowledge of local geography was not always accurate. Observations of human activity It was noted that in the Sudd area an alarming intensity of oil exploration constructions and activities are being developed. These consist of base camps, canals, seismic drilling sites and tracks created by large vehicles. This was also recorded by the WCS (Fay et al . 2007). Large concentrations of cattle exist along the borders of the Sudd marshes. Fishing exists in the whole area, at a low intensity level. Barges were observed navigating the main channel of the Bahr el Jebel system (White Nile).

The bird names have been listed and classified according to the scientific codes. An etymological study has been presented for scientific names, including genus and species. If it was possible we have provided the etymology of Persian and Gilaki native names of the birds. According to our best knowledge, there was no previous report gathering and describing the ornithological fauna of this part of the world. Gilan province, due to its meteorological circumstances and the richness of its animal life has harbored a wide range of animals. Therefore, the nomenclature system used by the natives for naming the animals, specially birds, has a prominent stance in this country. Many of these local and dialectal names of the birds have been entered into standard language of the country (Persian language). The study has presented majority of comprehensive list of the Gilaki bird names, categorized according to the ornithological classifications.

  • SURVEY of LOZA BAY, NORTH WEST of MADAGASCAR by FELIX Razafindrajao, Durrell Wildlife Conservation Trust Programme Madagascar August 2015
    WATERBIRD SURVEY OF LOZA BAY, NORTH WEST OF MADAGASCAR By FELIX Razafindrajao, Durrell Wildlife Conservation Trust Programme Madagascar August 2015 SUMMARY Through the ABC small grants scheme, three surveys of waterbirds were carried out in Loza Bay, north-west Madagascar in 2014 and 2015 (24 August to 02 September 2014 & 01-07 December 2014 and 10-15 February 2015). This was the first time that this important area of mangrove and bay has been surveyed for waterbirds. In total 37 waterbird species were recorded, belonging to 10 families. Four species are threatened with extinction; Madagascar fish-eagle Haliaeetus vociferoides (CR), Humblot’s heron Ardea humbloti (EN), Madagascar sacred ibis Threskiornis bernieri (EN), and Madagascar teal Anas bernieri (EN). Significant numbers of greater and lesser Flamingo Phoenicopterus ruber and Phoeniconaias minor were recorded during the surveys. In addition, 30 forest bird species were inventoried; all of them were endemic or regionally endemic species. Interviews were also conducted with local people, to collect information on their use of natural resources. Results from the interviews showed that local people are predominantly fishermen and there is significant pressure on natural resources through unsustainable use and disturbance. INTRODUCTION Loza Bay in the North West of Madagascar, district of Analalava and Antsohihy, is rich in biodiversity and plays an important role in the economy of the Sofia region. Three major rivers flow into the Loza Bay: the Tsinjomorona, the Maevarano and the Anjingo which feed into several wetland habitats for waterbirds. The bay is also important for transportation for local people as it links the Antsohihy and Analalava districts.

Despite new input from molecular systematics, consensus could only be partially reached. The initial, gross (sub)classification based on morphology and comparative anatomy was mostly supported by molecular data. The rich fossil record of cervids has never been extensively tested in phylogenetic frameworks concerning potential systematic relationships of fossil cervids to extant cervids. The aim of this work was to investigate the systematic relationships of extant and fossil cervids using molecular and morphological characters and make implications about their evolutionary history based on the phylogenetic reconstructions. To achieve these objectives, molecular data were compiled consisting of five nuclear markers and the complete mitochondrial genome of 50 extant and one fossil cervid species. Several analyses using different data partitions, taxon sampling, partitioning schemes, and optimality criteria were undertaken.

Oooh man I was right! The trip started in paradisiacal surroundings on the island of Mahe, the largest of all islands that together form the Seychelles. Before embarking the Silver Discoverer , we planned some pre-tour birding. In the afternoon we made an outing to find the rare Seychelles White-eye, Seychelles Blue-Pigeon, and Seychelles Sunbird. Rapidly they were found, and good looks were enjoyed by all. In the evening after dinner we went out for probably the rarest and most difficult bird of the entire tour, the Seychelles Scops-Owl. For a long time we heard no response, but just before we decided to leave the designated spot we heard one quick rasping call. Soon after, we found the bird in full delight—just amazing! The enchanting Seychelles Sunbird has a very restricted range (photo M.Valkenburg) Our journey would take us from several Seychellois islands to Madagascar, visiting the world-famous Aldabra Atoll on the way, ending the trip with visits to Reunion and Mauritius. This adventure was one-of- a-kind, with our program visiting so many difficult to reach places where we had the chance of finding many of the world’s most hard-to-get endangered species.

    i7 A CRITIQUE OF CRACRAFT'S CLASSIFICATION OF BIRDS STORRS L. OLSON National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560 USA ABSTRACT.•A recently proposed "phylogenetic" classification of birds (Cracraft 1981b) is not constructed according to dadistic principles and contains little information to support most of the taxa proposed in it. That which is presented is frequently misleading or erro- neous. The nomenclature used is inconsistent and ungrammatical. In failing to provide synapomorphies to cluster taxa, in using data that are not presented in a primitive-derived sequence, in citing differences as evidence of nonrelationship, and using convergence to refute phylogenetic hypotheses, Cracraft commits the very methodological transgressions for which he has long criticized other systematists.
