To date, 29 information about the diet of the species is insufficient for a comprehensive understanding of their 30 ecology. We studied the diet composition of breeding Black Harriers using ca. 1000 pellets (> 1700 31 identified prey) collected at nest sites in two geographical regions (coastal vs. interior-mountain) 32 over 10 breeding seasons (2006-2015). -
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. -
Rheboksfontein-Aurora Power Line Alternatives 1A-E
RHEBOKSFONTEIN-AURORA POWER LINE ALTERNATIVES 1A-E Avian Basic Assessment Re-revised Prepared for: Prepared by: EXECUTIVE SUMMARY This study contains a brief review of recent literature on power line impacts on avifauna, and identifies potential impacts associated with five alternative 132 kV power lines proposed for the Rheboksfontein wind farm near Darling, Western Cape. The possible impacts are: (i) minimal aerial-habitat alteration by the power lines themselves (due to existing lines along most of the planned routes) and their associated substations, (ii) disturbance by construction and maintenance activities, (iii) possible displacement or disturbance of sensitive species; and most critical (iv) direct collision with the power line network. Electrocution of avifauna is a lesser problem for all but the largest species on the power line infrastructure. The impact zone of the five alternative power line routes (1A, 1B, 1C, 1D, 1E) lies within the Swartland Shale Renosterveld and Swartland Renosterveld vegetation zones. Up-to-date bird atlas data from the region indicates that habitat around the northern option supports up to 157 bird species, including 11 threatened (red-listed) species, and 16 collision-prone species ranked in the top 100 species. Flocks of flamingos numbering over a thousand birds were present in this area. Avian mortality was common under the present lines and 11 birds were found dead under seven spans adjacent to the largest pan. These included red-listed Blue Cranes, red- listed Flamingos and geese and ibises. Thus the southern end of this line is designated a very high risk area and a no-go area for further lines. -

Trip Report Sept
South Africa Birding & Wildlife | Trip Report Sept. 15 – Oct. 1, 2018 | Written by Participant Karen Worcester Photos by Greg Smith With Guides Nick Fordyce, Dalton Gibbs, and Greg Smith, and participants Karen, Dawn, Ralph, Sheri, Robert, Corinne, Andrea, Rensje, Biny, June, Judith, and Wendy Monday, September 17 Arrivals Today was arrival day, with everyone making their way to the Greenwood Guesthouse, which would be our lodging for the next three nights. One of the commonly seen menu items in this part of the world is Butter Curried Chicken, which was served for dinner. Here we met Nick and Dalton, who along with Greg, would be our guides for the next two weeks. All three were energetic, knowledgeable, and charming. Dalton, who managed a reserve system in the Cape areas as his day job, is an encyclopedia for the natural history of this area. He was well versed in botany, could provide geological, geographical, political, and social context with ease, and had a sense of humor as well. He gave an overview of our trip and the extraordinary South African biome we would be exploring. Nick was lively, funny, and kind, and they made a great team. At least 20% of Africa’s plant diversity is in the Cape Town area. There are 319 threatened species and 13 which are already extinct. As small as it is, it is considered the sixth floral kingdom of the world, with 1000 plant species per square kilometer. For example, there are 700 species of Erica (heather) here, while Scotland has only three. Birds are equally diverse, with 950 species and 144 endemics! In this area, the warm waters of the Indian Ocean meet the cold water of the Atlantic, and the climate is “Mediterranean.” In addition, there is great topographic diversity, which causes diversification through isolation. -
Avifauna Survey
AVIFAUNA SURVEY Prepared by: Dr W. Richard J Dean, Research Associate at the DST/NRF Centre of Excellence at the Percy FitzPatrick Institute of African Ornithology at the University of Cape Town Reviewed and edited by: Dr Penn Lloyd, Principal Ecologist and Director at Biodiversity Assessment and Management Pty Ltd; and Patrick Morant, SACNASP Professional Natural Scientist (Reg. No. 401514/83). Table of content II. SURVEY RESULTS 3 III. INFRASTRUCTURE AND POTENTIAL IMPACTS ON BIRDS 10 IV. CONSERVATION RECOMMENDATIONS FOR FURTHER LONG-TERM MONITORING AND RESEARCH PROGRAMME WITHIN THE SKA CORE AREA AND KCAAA1 13 V. LIST OF ALL BIRD SPECIES RECORDED WITHIN KCAAA1 14 VI. REFERENCES 22 I. Introduction The Square Kilometre Array (SKA) is situated in the Nama Karoo, so only those bird species that occur in the Nama Karoo will be discussed here. The study area of the strategic environmental assessment (SEA) for the first phase of the SKA project (SKA1_MID) covers 153 Quarter Degree Grid Cells (QDGC)1, fairly well covered by participants in the Bird Atlas project in the late 1980s and early 1990s with lists of bird species for all 153 QDGC. Data for the 153 QDGC are a combination of the South African Bird Atlas Project data, museum specimen data and sight data (WRJD pers. obs.) and includes a recent bird list compiled by Etienne Marais. The avifauna of the Nama Karoo is not distinctive, and there are no families of birds endemic to the Karoo, but there are 25 species that are near-endemic to the region (Table 1). Only two species, Red Lark Calendulauda burra and Sclater's Lark Spizocorys sclateri, whose distribution ranges are almost entirely within the Nama Karoo, can be considered true endemics to the Nama Karoo. -
Message from the President
Volume 23, Number 2 November 2014 MESSAGE FROM THE PRESIDENT What a great meeting we had in Corpus Christi! I hope that all of you that were able to attend had a great time and got to see some of the local specialties. If you haven’t had the chance, please drop Kate Davis a message congratulating her on yet another great Raptor Research Conference. The amount of work and stress that goes into these meetings cannot be understated. I know several unforeseen issues came up, all of which Kate dealt with behind the scenes with no drama. We owe her a big one! The day before the meeting officially started was the annual meeting of the Board of Directors. Unfortunately, several officers and board members were unable to attend, but we had a very constructive meeting none-the-less. Our recent election results were announced, and I’m pleased to recognize the outgoing and incoming officers and board members. First, Ted Swem has been our Vice President for several years now and felt it was time to take a break. I personally appreciate the service Ted has given the RRF as our Vice President; he has been a stable and steady voice and a great help for me during my first year as president. But, I could not be happier that, starting 1 January, Libby Mojica will be taking over as Vice President. Brian Washburn and Jennifer Coulson were elected in as new Directors, and Fabrizio Sergio and Rob Bierregaard were re-elected to their posts. I appreciate Rick Harness and Miguel Ferrer for their service on the board, and look forward to continuing to work with them in other roles serving RRF. -
Hartebeest Wind Energy Facility
Prepared for: Juwi Renewable Energies (Pty) Ltd. Hartebeest Wind Energy Facility Avifaunal Specialist Impact Assessment Scoping Report Scoping Report August 2016 www.bioinsight.co.za EXECUTIVE SUMMARY This scoping report aims to provide a preliminary evaluation of the potential interactions between birds and the proposed Hartebeest Wind Energy Facility, situated about 4 km to the south east of Moorreesburg in the Western Cape Province of South Africa. The project considers a layout with 40 turbines. The land main use is for cereal plantation, combined with some sheep and cattle grazing. Therefore, the natural habitats are highly transformed. Some tree stands appear scattered throughout the study area. Some hills covered with natural vegetation add some steep slopes to the otherwise gently undulated landscape. The highest altitudes are reached in a series of hills running in a northwest to southeast direction traversing the study area. Up to 225 bird species can potentially occur within the Hartebeest WEF area and its immediate surrounds, based on the data sources consulted. Out of those, seventeen species are of special conservation concern including five “Endangered”, seven “Vulnerable” and five “Near-threatened” species (Taylor, PeacocK & Wanless 2015). From the list of potentially occurring species, 50 species were selected as sensitive (i.e. focal) species for the impact assessment process in Hartebeest WEF due to their conservation status, regional endemicity and sensitivity to wind development impacts. A preliminary site visit confirmed the occurrence of twenty-eight sensitive species. Ten of these species are especially sensitive due to an unfavourable conservation status, i.e.: Greater Flamingo (Phoenicopterus roseus), Lesser Flamingo (Phoeniconaias minor), Secretarybird (Sagittarius serpentarius), Verreaux’s Eagle (Aquila Verreauxii), Martial Eagle (Polemaetus bellicosus), African Marsh Harrier (Circus ranivorus), BlacK Harrier (Circus maurus), Lanner Falcon (Falco biarmicus), Blue Crane (Anthropoides paradiseus) and Ludwig's Bustard (Neotis ludwigii). -
Does Timing of Breeding Matter Less Where the Grass Is Greener? Seasonal Declines in Breeding Performance Differ Between Regions in an Endangered Endemic Raptor

Seasonal declines in breeding performance differ between regions in an endangered endemic raptor. Nature Conservation 15: 23–45. doi: 10.3897/natureconservation.15.9800 Abstract The timing of breeding can strongly influence individual breeding performance and fitness. Seasonal declines in breeding parameters have been often documented in birds, particularly in the Northern Hemi- sphere. Fewer studies have investigated whether seasonal declines in productivity vary in space, which would have implications for a species’ population dynamics across its distributional range. We report here on variation in the timing of breeding in the Black Harrier (Circus maurus), an endangered and endemic raptor to Southern Africa. -
Fairest Cape to Kruger 11Th – 27Th September, 2015
Fairest Cape to Kruger 11th – 27th September, 2015 Barrier of Spears extension 27th September – 3rd October, 2015 Set Departure tour Tour leader: Charley Hesse Report by Charley Hesse. Photos by Charley Hesse & Andrew Spencer With stiff competition, Buff-spotted Flufftail was voted bird of the trip (Andrew Spencer) There many different ways to birdwatch in South Africa, and with a small group of serious birdwatchers, we had a fast pace tour and accumulated a very large number of species. With a trip list of 494 species of birds, 67 species of mammals, plus many reptiles, amphibians and butterflies, it was one of our most successful tours to date. It was especially impressive considering that this didn’t even include a pelagic (which was sadly cancelled due to weather conditions). In addition to the huge species haul, our list included most of the available endemics (including both rockjumpers and sugarbirds) plus many other seldom seen birds. As well as the obvious star birds like African Penguin and Blue Crane, we did particularly well with certain groups, with 9 species of bustard, 14 species of larks (including the very rare Rudd’s), 32 species of hawks and eagles (including Crowned Hawk-Eagle & Fasciated Snake-Eagle) and 9 species of owls (including African Grass-Owl, Cape Eagle-Owl and the Holy Grail of African birding, Pel’s Fishing Owl). Mammals feature heavily on this tour and highlights from our list included Cheetah, White & Black Rhinos, Porcupine, Meercat & Southern Rights Whales. Of course the world class reserves, stunning scenery, high-quality lodging and food plus very friendly people didn’t go unnoticed either.
