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. -

OBSERVATIONS ON THE EVENING DEPARTURE AND ACTIVITY OF WINTERING SHORT-EARED OWLS IN NEW JERSEY THOMAS BOSAKOWSKI ABSTR^CT.--WinteringShort-eared Owls (Asioflammeus) were primarily crepuscularand nocturnal. Roostdeparture occurred most frequently after sunset(83%) with mostexceptions occurring on heavily overcastdays. Owls usually departed singly or in tandemand engaged in a steadydirect flight, presumably to a predeterminedhunting area. Hunting was rarely initiatednear the roostsite. Night observations up to 5 hr after sunsetrevealed that owls huntedcontinuously into the night and were not merely crepuscular.Despite their reputationas an on-the-wingpredator, extended periods of perch-huntingwere oftenobserved after sunset,particularly on windlessnights. Active hunting from percheswas evidenced by a continualseries of pouncesand huntingflights that werelaunched from the sameor nearbyperches.

However, males of this species in southwestern France have female-like plumages, lacking gray feathers, and thus, gender determination is impossible by using coloration alone. We investigated sex determination using biometric parameters in a study site located in southwestern France. From one to six measurements (body mass, bill length, wing chord length, tarsus length and width, and tail length) were taken from 243 marsh harriers of known gender (156 males and 87 females), marked in the study site, and subsequently re-sighted. Additionally, 30 marsh harriers specimens were measured by two observers to establish within and between observer repeatability values, as well as within bird repeatability for the six biometric parameters. Using quadratic Discriminant Analysis, we showed that it was possible to sex individuals of this species with .99% accuracy on the basis of only two parameters: bill length and body mass. Actually, using bill length alone provides very good indication of gender (accuracy . -
Identifying a Bird Species from the Temple of Hatshepsut at Deir El-Bahari
The secretarybird dilemma: identifying a bird species from the Temple of Hatshepsut at Deir el-Bahari Abstract: Known from a few representations in Predynastic Egyp- tian art, the secretarybird has otherwise been elusive, in the art of Pharaonic Egypt as well as the scientific discourse on icono- graphic imagery of birds in ancient Egypt. The author’s studies of the animal decoration at the Temple for her doctoral dissertation identified three images of birds belonging most likely to the same species, depicted in the context of the expedition of Hatshepsut shown in the Portico of Punt. The zoological identification of the species as the secretarybird (another possibility is the African harrier-hawk) derives from an in-depth analysis of the bird’s sys- tematics, appearance, distribution and habitat, as well as behavior, which are essential for proper species recognition and instrumen- tal for understanding the rationale behind bringing this particular bird from the “God’s Land”. Iconographic features contesting this identification and suggesting a different species, that is, the African harrier-hawk, are discussed based on a combination of theoretical background, material analysis, on-site interviews with experts and the author’s personal experience with the species. Keywords: African animals, birds in Ancient Egypt, secretarybird, African harrier-hawk, temple of Hatshepsut, Deir el-Bahari, Hat- shepsut Punt expedition, temple decoration A bird depicted in possibly three separate scenes from the Southern Middle Portico of the Temple of Hat- shepsut in Deir el-Bahari, documented in 2012 by the author as part of her extended study of animals in the decoration of this Eighteenth Dynasty sanctuary [Fig. -

Black Harrier Research
Black Harrier Research Protecting a species through research and conservation Black Harriers and other Red Data species in the proposed Boulder Wind Farm: a re-assessment, January 2020 Dr R.E. Simmons Black Harrier Research Group, FitzPatrick Institute, UCT Dr R E Simmons, Honorary Researcher, Percy FitzPatrick Institute, University of Cape Town, Rondebosh, 7700, Cape Town, South Africa [email protected] +27 (0)82 780 0133 RATIONALE The proposed Boulders Wind Farm in the Cape Columbine area, east of Paternoster, has attracted public criticism from conservation groups in the area due to its proximity to various nationally important biodiversity areas, and visual and archaeological concerns. I was asked by the concerned groups, as a specialist on raptors, and particularly Endangered Black Harrier Circus maurus, to re-assess the Red Data species in the area and review the avian EIA Report prepared for the Boulders wind farm site. The Cape Columbine area has recently been identified as a nationally important core area for breeding harriers, so I spent three days on site in late January 2020 to prepare a specialist report as part of the Appeal Process. I also spoke to local birders and met with the conservationists. This is a report of my findings. BACKGROUND The proposed Boulders site is a Wind Farm comprising 45 turbines of hub height 120-m, placed on 10 farm portions surrounding the existing and operational West Coast 1 Wind Farm (WC1WF). The West Coast 1 site was subject to an avian assessment, mitigation measures, and has at least one year of carcass data available. -

Gymnogene Been No Apparent Change in Distribution in the Cape Prov- Kaalwangvalk Ince (Boshoff Et Al
244 Accipitridae: vultures, kites, hawks, eagles, buzzards and harriers peaked March–April. The reason for this is un- clear but, together with the paucity of breeding data from Zones 1 and 2, the possibility that there is east–west migration in the north requires fur- ther investigation. Breeding individuals are thought to be largely sedentary but they may oc- casionally wander during the nonbreeding season (Del Hoyo et al. 1994) and immatures are be- lieved to disperse from natal territories (Hockey et al. 1989). Breeding: Most breeding activity was recorded in eastern areas (Zones 5–8), mainly September– March. The reason for the general lack of breed- ing records from the northwestern parts (Zones 1 and 2) is not known; either breeding sites were overlooked or the species may be primarily a nonbreeding visitor from the east. Egglaying is known to be restricted to early summer (August– December, mainly September–October) in south- ern Africa (Winterbottom 1968a; Dean 1971; Irwin 1981; Tarboton et al. 1987b).

Diet and Foraging Ecology of African Harrier Hawk (Polyboroides Typus) in Ehor Forest Reserve, Edo State, Nigeria
Journal of Researches in Agricultural Sciences Vol. 5 (2), 2017 Diet and Foraging Ecology of African Harrier Hawk (Polyboroides typus) in Ehor Forest Reserve, Edo State, Nigeria 1E.F. Okosodo, 2J.O. Orimaye, 1O. Aladelusi and 3O.O. Kolawole 1Department of Ecotourism and Wildlife Management, The Federal University of Technology, Akure, Ondo State 2Department of Forest Resources and Wildlife Management, Ekiti State University Ado-Ekiti, Ekiti State 3Department of Hospitality and Tourism, Federal Polytechnic, Ilaro Ogun State Email: [email protected] Abstract Feeding is an indispensable activity in the life of birds. It is crucial for their survival but the demands of food acquisition impose significant challenges to both the physiology and behavior of birds. Thus, this study on the feeding ecology of African harrier hawk is imperative for understanding the species adaptation to environments and also a crucial factor to be considered while examining their economic status. This research study investigated the diet and foraging ecology of the African harrier-hawk (Polyboroides typus) in Ehor Forest Reserve, Edo State, Nigeria. Direct field observation method was used to collect data for 12 months on the diet and foraging ecology of the bird species. The study area was divided into three compartments according to land use types, (mature forest, logged area, and farmlands). The results show that the African harrier-hawk consumed a variety of small animals, insects and fruits of some plant species. The frogs, lizards, adults, eggs of bird species and insects constituted 87.25% of the diets while plant resources made up 12.75%. The major diet resources were bird species belonging to the family Ploceidae and frogs; and the fruits of oil palm (Elaeis guineensis) and African pear (Dacryodes edulis).
