Lucia at animal flight lab

Lucia is celebrated each year on 13th December, with a choir consisting of Lucia herself (wearing candles in the hair), terns, staffans, nomes and other creatures. This year Lucia did not show up at the Biology Department, but the traditional beverages and ginger cookies were consumed as usual. Also members of the flight lab participated in the celebrations, taking a break from a brain-storming activity during the weekly lab-meeting. What should we like a new PIV-system to do for us? - that is the question.

CAnMove 2nd conference

During two days members of CAnMove have attanded the 2nd conference, whith invited talks given by various canmovians, including PhD-students, postdocs, seniors and two members of the Scientific Advisory Board. Marilyn Ramenofsky talked about her work on physiological adaptations to the annual cycles, using two populations the white-crowned sparrow, while Steven Reppert gave an overview about his lab's work monarch butterfly migration (see picture). The Animal Flight lab was well represented and gave two presentations (Christoffer and Anders). During the conference we also discussed how to further improve the activities within CAnMove, and how to facilitate even better research. It was a great meeting and now we just have to dig into it and move forward!

Prestigious postdoc to Florian Muijres

We are very happy that animal flight lab member Florian Muijres receievd 2-year postdoc from VR (The Swedish Research Council). These postdocs are awarded in severe competition and allows the recipient to spend 2 years abroad. Florian will now go to the University of Washington, Seattle, USA, where he will work in Michael Dickinson's lab. We wish all the well for Florian's postdoctoral stay, but we also hope there is a chance that we will see him again in Lund, as these postdocs usually come with a return-funding. But now we look forward to see what interesting questions Florian will investigate in the big country to the left of the Atlantic. Congratulations, and all the best of luck!

New birds to the wind tunnel

During the weekend two new birds, Diamond doves, moved in to the wind tunnel aviary. The hope is that they will learn to fly in the wind tunnel and that we will be able to find something interesting out from these flights. These are small doves living in arid habitats of Australia in the wild, while they have become popular pet-animals because they easily reproduce in captivity. Hopefully these pigeons will be flying in the wind tunnel soon, and allow us to study the wing-beat kinematics, the wake of flapping and maybe also gliding flight. Stay tuned and you will soon hear more about this!

Hovering in a whiteye

A research team based in Taiwan has published a new PIV-study on the hovering aerodynamics in hovering Zosterops japonicus, which birdwatchers know as whiteyes. These 6-7 g birds are capable of hovering, i.e. flying at zero forward speed, which was studied in a special hovering chamber. Wing kinematics and induced vortex flows were monitored, which uncovered a new mechanism for enhancing lift force in hovering in birds - a ventral clap-and-fling. This mechanism is known from some insects already since the dane Torkel Weis-Fogh's pioneering work, but had not been observed in birds before. Interestingly some of the high-lift mechanism previously known from insect flight are now being observed in birds and bats, mainly due to the application of the PIV-technique to animal flight. We, the Lund crew, are happy to see this approach spreading to other labs studying animal flight. The paper can be found in Experiments in Fluids.

Migration Ecology Course for PhD students

The biannual course in migration ecology at Lund University started yesterday. After an introduction the students give short, 15 min, presentations about their projects during the first two days. Then, the first lecture day starts as usual with locomotion. This years line-up is Colin Pennycuick, Anders Hedenström, Florian Muijres and Christoffer Johansson. As before we focus on animal flight and swimming. There is also an exercise involving the measurement of aerodynamic morphology and using it to calculate various performance measures using Colin Pennycuick's progrom Flight. This course is a great experience for both students and lecturers. For more information about the program have a look at www.canmove.se.
