Dr. Katrin Ludynia, aka "Katta", post-doctoral fellow at the Animal Demography Unit at the University of Cape Town, and I are seasoned veterans. Veterans at deploying GPS data loggers on unsuspecting breeding African Penguins. These loggers regularly record the position of the penguin as well as other pertinent information such as time, dive depth and water temperature. This in turn provides important insights on penguin foraging areas, habitats, ranges and behaviour which are vital for guiding conservation management of this endangered species. The general idea is to equip a penguin with such a device for about two days to obtain precise details of one foraging trip. At about 75 g the device is small enough not to be a burden to the penguin but it also means that it is limited in terms of how much data can be stored; depending on what settings are chosen, its battery life span is about three days. The device has to be retrieved in order to download the data and great care is therefore needed to choose a penguin which is likely to return to the colony after a foraging trip. Katta and I have done this many times and by now are pretty good at choosing the right penguin to carry our €2 300 piece of equipment.
