Summary Bustards comprise a highly threatened family of birds and, being relatively fast, heavy fliers with very limited frontal visual fields, are particularly susceptible to mortality at powerlines. These infrastructures can also displace them from immediately adjacent habitat and act as barriers, fragmenting their ranges. With geographically ever wider energy transmission distribution grids, the powerline threat bustards is constantly growing. Reviewing published unpublished literature up...
Abstract Line markers are widely used to mitigate bird collisions with power lines, but few studies have robustly tested their efficacy. Power line an escalating problem for several threatened species endemic southern Africa, so it is critical know whether or not marking works adequately manage this problem. Over 8 yr, a large-scale experiment was set up on 72 of 117 km monitored transmission lines in the eastern Karoo, South assess reduce collision mortality, particularly Blue Cranes (Grus...
Road ecology is becoming an increasingly important aspect of conservation biology. Carcasses lying on the road often confront visitors travelling to Kgalagadi Transfrontier Park between Upington and Twee Rivieren Rest Camp. This study investigated species killed, factors contributing their deaths, suggested solutions curtail these mortalities. Twelve surveys record mammal bird mortalities were conducted R360 main (261 km) from January September 2007. One hundred eighty four carcasses...

Waterbirds in stochastic environments exhibit nomadism order to cater for the unpredictable availability of water resources. Lesser flamingos Phoeniconaias minor have long been thought be nomadic waterbirds. In southern Africa, conservation efforts lesser are hampered by a lack knowledge about their movement trajectories. To investigate ecology we fitted GPS–GSM transmitters 12 adults and tracked movements over four years, from March 2016 February 2020. Net squared displacement (NSD) was...
Summary Monitoring population trends is important for evaluating the effectiveness of conservation interventions. An annual aerial census three crane species, Grey Crowned Crane Balearica regulorum , Blue Anthropoides paradiseus and Wattled Bugeranus carunculatus was performed in KwaZulu-Natal province, South Africa over past 23 years. These species are listed as ‘Endangered’, ‘Vulnerable’, respectively, on IUCN Red List. chosen a key site monitoring it covers an region cranes that has...
As human populations and developments expand, it is inevitable that interactions between wildlife electrical infrastructure will increase. Such the case in protected areas, where mammal electrocutions often occur as a result of damaged infrastructure. In previous study, camera trap survey along power line Kruger National Park (Kruger) revealed large mammals [particularly Cape buffalo, Syncerus caffer, rhinoceros (Ceratotherium simum Diceros bicornis) African elephant, Loxodonta africana]...
Lesser Flamingos Phoeniconaias minor regularly collide with power lines in South Africa. Attaching light-emitting markers to overhead wires seems be an effective mitigation measure; however, the cost of these devices is prohibitive large-scale installation. Spatial predictions about flamingo collision risk are thus important for achieving efficient and proactive mitigation. In this study, was defined as a combination factors related threat exposure. A habitat suitability index developed...
