Tour Report Tour Participants: Marcus John (leaders) with six Naturetrek clients Summary The Gambia is an ideal destination for a relaxed holiday and offers a great introduction to the diverse and colourful birdlife of Africa. We spent the week at the stunning Mandina Lodges, a unique place that lies on a secluded mangrove-lined tributary of the mighty River Gambia. The lodges are situated next to the creek and within the Makasuto Forest, which comprises over a thousand acres of pristine, protected forest. Daily walks took us out through the woodland and into the rice fields and farmland beyond, where a great range of birds and butterflies can be found. It was sometimes hard to know where to look as parrots, turacos, rollers and bee-eaters all vied for our attention! Guinea Baboons are resident in the forest and were very approachable; Green Vervet Monkeys were seen nearly every day and we also found a group of long-limbed Patas Monkeys, the fastest primates in the world! Boat trips along the creek revealed a diverse selection of waders, kingfishers and other waterbirds; fourteen species of raptor were also seen during the week. -

The study estimated, investigated and examined trees species and avian frugivore in terms of their diversity. Point-Centered Quarter Method (PCQM) was used for vegetation analysis while random walk and focal observation was used for bird frugivore identification and enumeration. data was collected from six locations coinciding with the local administrative areas within the Federal Capital Territory. These were, the Abuja Municipal Area Council (AMAC), Abaji, Bwari, Gwagwalada, Kuje and Kwali. AMAC is designated as urban while the remaining five sites are designated as sub-urban. The highest number of fruit tree species was encountered in AMAC (30), followed by Abaji (29) while 27, 25, 19 and 11 fruit tree species were encountered in Kwali, Bwari Gwagwalada and Kuje respectively. The similarity or otherwise dissimilarity in fruit tree species composition between each pair of the enumerated sites showed Gwagwalada and Kuje as the most similar, and the similarity or otherwise dissimilarity in frugivorous bird species composition between each pair of the enumerated showed higher species similarity between the AMAC and each of the other sites, and between each pair of the sites than that of the fruit trees in the respective sites. -

We explored all of these and more during our 25-day adventure across the country. Highlights were many and included Orange River Francolin, thousands of Cape Gannets, multiple Secretarybirds, stunning Knysna Turaco, Ground Woodpecker, Botha’s Lark, Bush Blackcap, Cape Parrot, Aardvark, Aardwolf, Caracal, Oribi and Giant Bullfrog, along with spectacular scenery, great food and excellent accommodation throughout. ___________________________________________________________________________________ Despite havoc-wreaking weather that delayed flights on the other side of the world, everyone managed to arrive (just!) in South Africa for the start of our keenly-awaited tour. We began our 25-day cross-country exploration with a drive along Zaagkuildrift Road. This unassuming stretch of dirt road is well-known in local birding circles and can offer up a wide range of species thanks to its variety of habitats – which include open grassland, acacia woodland, wetlands and a seasonal floodplain.

Our flight in from the UK was delayed so no time for any real birding on this first day of our “Chilled Birding Tour”. Our local guide Tijan and our ground crew met us at the airport. We piled into Tijan’s well used minibus as Little Swifts and Yellow-billed Kites flew above us. A short drive took us to our lovely small boutique hotel complete with pool and lovely private gardens, we were going to enjoy staying here. Having settled in we all met up for a pre-dinner drink in the warmth of an African evening. The food was delicious, and we chatted excitedly about the birds that lay ahead on this nine- day trip to The Gambia, the first time in West Africa for all our guests. At first light we were exploring the gardens of the hotel and enjoying the warmth after leaving the chilly UK behind. Both Red-eyed and Laughing Doves were easy to see and a flash of colour announced the arrival of our first Beautiful Sunbird, this tiny gem certainly lived up to its name! A bird flew in landing in a fig tree and again our jaws dropped, a Yellow-crowned Gonolek what a beauty! Shocking red below, black above with a daffodil yellow crown, we were loving Gambian birds already. -

WORKING with TURACOS Musophagidae Spp
125 AL WABRA WILDLIFE PRESERVATION, QATAR: WORKING WITH TURACOS Musophagidae spp. by Simon Bruslund Jensen The turacos are a primitive, almost primeval-looking family of medium to large-sized birds, most closely related to the cuckoos. The 23 species are distributed exclusively in tropical African forests and savannahs. Most species are beautifully coloured in shades of green, blue and red, and are well known for their unique feather pigments, the so-called turacin and turacoverin, found only in this family. Sven Hammer/AWWP A Prince Ruspoli’s Turaco Tauraco ruspolii approaching a waterhole close to Arero, Ethiopia. Due to their appealing appearance, many of the species have for many years been popular in zoos and private collections. However, just a few years back, captive breeding would never have been considered as an option for the conservation management of turacos, as they had long been considered as delicate and rather difficult to breed in captivity. In recent years the methods used for keeping and breeding turacos have improved a great deal, due largely to the systematic approach by dedicated individuals and public collections such as the zoos in Cologne, Germany and Houston, Texas, USA. Now for the first time, it seems possible to establish self-sustainable captive populations, in particular within the 126 JENSEN - TURACOS framework of regional and international cooperation, with studbooks being maintained to ensure the necessary exchange of bloodlines. This is in line with the identification of more and more threats to several turaco species in the wild, especially to some of the unique subspecies with limited distribution. -

Zimmer) This was the second January departure of our increasingly popular Uganda Highlights Tour, and it proved an unqualified success in delivering up-close-and-personal observations of wild Mountain Gorillas, wild Chimpanzees, and the bizarre Shoebill. Beyond these iconic creatures, we racked up over 430 species of birds and had fabulous encounters with Lion, Hippopotamus, African Elephant, Rothschild’s Giraffe, and an amazing total of 10 species of primates. The “Pearl of Africa” lived up to its advance billing as a premier destination for birding and primate viewing in every way, and although the bird-species composition and levels of song/breeding activity in this (normally) dry season are somewhat different from those encountered during our June visits, the overall species diversity of both birds and mammals encountered has proven remarkably similar. After a day at the Boma Hotel in Entebbe to recover from the international flights, we hit the ground running, with a next-morning excursion to the fabulous Mabamba wetlands. Victor Emanuel Nature Tours 2 Uganda Highlights, January 2020 Opportunistic roadside stops en route yielded such prizes as Great Blue Turaco, Lizard Buzzard, and Black-and-white-casqued Hornbill, but as we were approaching the wetlands, the dark cloud mass that had been threatening rain for the past hour finally delivered. -
A Community Effort to Annotate the Chicken Genome

The copyright holder for this preprint (which was not certified by peer review) is the author/funder, who has granted bioRxiv a license to display the preprint in perpetuity. It is made available under aCC-BY 4.0 International license. Submitted to Cytogenetic and Genome Research as part of the Third Report on Chicken Genes and Chromosomes The Avian RNAseq Consortium: a community effort to annotate the chicken genome (Prepared by Jacqueline Smith, David W. Burt and the Avian RNAseq Consortium) Publication of the chicken genome sequence in 2004 (International Chicken Genome Sequencing Consortium 2004) highlighted the beginning of a revolution in avian genomics. Progression of DNA sequencing technologies and data handling capabilities has also meant that genome sequencing and assembly is now a relatively simple, fast and inexpensive procedure. The success seen with the chicken genome was soon followed by the completion of the zebra finch genome (Warren et al., 2010), an important model for neurobiology (Clayton et al., 2009), again based on Sanger sequencing. In recent years the rapid advances in Next Generation Sequencing (NGS) technologies, hardware and software have meant that many more genomes can now be sequenced faster and cheaper than ever before (Metzker, 2010). The first avian genome to be sequenced by NGS methods was the turkey (Dalloul et al., 2010), which was also integrated with genetic and physical maps thus providing an assembly of high quality, even at the chromosome level. Recently, NGS has been used to sequence the genomes of a further 42 avian species, as part of the G10K initiative (Genome 10K Community of Scientists, 2009).
