Mark Boorman (1952) lives in Swakopmund (NAM) and has been dedicating virtually all of his spare time the past decades to the study of terns and other seabirds on the Namibian coast. He is a keen bird ringer and ring reader of European terns in particular. At the moment he is heavily involved in a large conservation project on Lappet-faced Vultures in Namibia as well as smaller projects on larks and penguins. In the past he has been collaborating with a group of Dutch researchers in a previous WIWO expedition to do tern and wader surveys on the Namibian coast. Mark will be the responsible for all field equipment such as nets, traps, rings, decoys, sound system, etc. He will participate in most of the fieldwork as an experienced tern ringer and catcher.
