Tanja is a student at the Nelson Mandela Metropolitan University who has an M.Sc. project on thermal tolerances of Southern Red Bishops. Tanja will capture bishops for metabolic rate measurements in two different locations: one with a mild coastal climate (Port Elizabeth) and the other location inland where seasonal and daily temperatures are extreme (Barkly East). Bishops in Barkly East will be captured between 22 July - 31 July 2010 with help from ringers Pat Cochran and Graham Grieve and trainees Liaan Minnie and Ryan Wasserman. Albert Schultz will help capture bishops in Port Elizabeth.
