Avian collision ecology

Research in in this category includes projects on the biology and population-level impacts and mitigation of bird collisions with man-made obstacles, as well as the implications of measured movement patterns for susceptibility to collision.

Review of avian collisions with overhead power lines: South African Perspectives

This review paper was compiled by Andrew Jenkins and co-authors while in the employ of the EWT. It integrates the findings of multiple quantitative research of bird:power line collisions from around the world, and summarises the current state-of-the-art, based on sound, empirical evidence, in a (South) African context.

The nature, frequency and consequences of collisions by large terrestrial birds with power lines in South Africa

Building on provisional data collected by Andrew Jenkins, Jessica Shaw did this ground-breaking work on crane and bustard collisions with power lines in South Africa as MSc and PhD theses respectively, registered at the FitzPatrick Institute, UCT, and under the supervision of Prof. Peter Ryan and Andrew Jenkins. Jessica was the first to fully quantify casualty rates of both Blue Crane and Ludwig’s Bustard on SA power lines, to assess the demographic consequences of this mortality, and to test the efficacy of line marking in mitigating this potentially unsustainable impact. She is now working for Scottish Natural Heritage in the UK, but is still publishing papers arising from her PhD.

Radar tracking as a means to predict Great White Pelican collision rates with a proposed wind farm on the Cape West Coast

This work was done by AVISENSE in collaboration with NCC Environmental Consulting, Geocline, EchoTrack and Dr Tim Reid of the FitzPatrick Institute, UCT, and on contract to Moyeng Energy (Pty) Ltd. The study was the first of its kind done in South Africa, and used radar to track the flights paths of Great White Pelicans in relation to a proposed wind energy development. After accumulating a large sample of 3-D flight tracks, we were able to model pelican collision risk and devise a potential impact mitigation scheme for the wind farm, based on operational management of the highest risk turbines in the proposed layout. With permission from Moyeng, we hope to publish the results of this study soon.
