Max Planck Institute for Ornithology (Radolfzell)

Birds provide an ideal subject of research for a variety of fundamental biologic questions. Bird song for example resembles human language in many ways. Researchers at the Max Planck Institute for Ornithology in Seewiesen want to find out how bird song has developed through learning process and what role neuronal principles and hormones play in this process. Furthermore they study the evolution of partner selection and loyalty of partners. Why do individuals differ in their mating behaviour and how does this affect their reproductive success, are examples of questions, that they search the answers for. At the Radolfzell Ornithological Station, a sub-institute, scientists research bird and other animal migration behaviour: how do animals get from one place to another and how do they survive? All data are being collected in an international database to be able to combine them and to do long term studies. Those data can be important for the humans in that aspect that birds and insects often spread diseases.

Sloths in the wild sleep a lot less than previously thought more
Many animal species have made their homes in towns and cities. However, the conditions they encounter there are different than those under which they would live in a natural environment. Henrik Brumm, Jesko Partecke and Bart Kempenaers from the Max Planck Institute for Ornithology in Seewiesen and Radolfzell are studying the effects of city living on our native songbirds. In the process, they have discovered some surprising behavioral changes.

Life on the Move

MPR 3/2012 Biology & Medicine
Whether birds that crisscross the globe, whales that navigate the vastness of the oceans or wildebeast on the African savannas – the major animal migrations in our world present an incomparable spectacle. Yet in many cases, surprisingly little is known about either their exact
destinations or how they get there. At the Radolfzell observatory of the Max Planck Institute for Ornithology, Martin Wikelski and his team use miniature transmitters to track a wide variety of species on their travels.
Recent decades have seen an accelerated extinction of wild plants and animals throughout the world. There is still a chance to stop it, at least in Germany. A simple model shows a way out of the bio - diversity crisis.

Evolution right in our backyard

2013 Partecke, Jesko
Behavioural Biology Ecology Evolutionary Biology Physiology

It is well established that urban areas have been successfully colonized by animals. Less is known about the extent to which urbanization causes ecological and micro-evolutionary changes in animals thriving in urban areas. Studies at the MPIO in Radolfzell elucidate that city life causes changes in behavior and underlying physiological mechanisms and that micro-evolutionary effects may play an important role. Current studies using newest radiotelemetry and micrologger technique aim to discover the impact of artificial city light at night on the daily and seasonal organization of urban animals.

Thin billed prions: “miniature albatrosses” measure climate change in the Southern Ocean

2010 Quillfeldt, Petra; Masello, Juan Francisco
Behavioural Biology Climate Research Ecology
The Southern Ocean is strongly affected by global change. A long-term study of Thin-billed prions, a small seabird feeding on zooplankton in these vast ocean areas, was designed to further our understanding of the changes that currently take place in this ecosytem. Further, this study will look at adaptations that enable the birds to cope with changing conditions, such as flexible provisioning behaviour and physiological regulation of timing and investments in the breeding cycle. more

Truth or dare: honesty of avian sexual signals

2006 Peters, Anne
Behavioural Biology Ecology
Trade-offs with immunity can theoretically enforce honesty on sexual signals through testosterone, that stimulates sexual traits but also suppresses immunity, and/or carotenoids, that can be used in ornaments or support immune functions. Recently, researchers at the Max Planck Institute for Ornithology found evidence for such trade-offs in male mallards. more
