![]() Using these data we built a life-size model of F. The dam allowed us to match the high-resolution images obtained from the digital camera with the corresponding images taken with the high-speed cameras. In addition, body images of the falcon were taken from two perspectives with a high-resolution digital camera. Flight trajectories were obtained with a stereo high-speed camera system. The presence of a well-defined background allowed us to reconstruct the flight path and the body shape of the falcon during certain flight phases. peregrinus were trained to dive in front of a vertical dam with a height of 60 m. Unfortunately, in freely roaming falcons, these high velocities prohibit a precise determination of flight parameters such as velocity and acceleration as well as body shape and wing contour. ![]() During a dive peregrines can reach velocities of more than 320 km h−1. This study investigates the aerodynamics of the falcon Falco peregrinus while diving. High-resolution pictures of the diving peregrine indicate that feathers pop-up in the equivalent regions, where flow separation in the model falcon occurred.ĭiving-Flight Aerodynamics of a Peregrine Falcon ( Falco peregrinus) Visualizations of the flow in the wind-tunnel uncovered details of the flow structure around the falcon's body, which suggests local regions with separation of flow. We compared these forces acting on the model with the data obtained from the 3-D flight path trajectory of the diving F. peregrinus and used it to measure the drag and lift forces in a wind-tunnel. During a dive peregrines can reach velocities of more than 320 km hâ»Â¹. Ponitz, Benjamin Schmitz, Anke Fischer, Dominik Bleckmann, Horst Brücker, Christoph ![]() To our knowledge, this is the first report of infection with Serratospiculum species in captive falcons in Europe.ĭiving-flight aerodynamics of a peregrine falcon ( Falco peregrinus). Treatment with ivermection (2 mg/kg SC) was effective, as none of the falcons excreted Serratospiculum species eggs 10 days after one dose. Eggs of Serratospiculum species (4 birds) and Capillaria species (11 birds), and oocysts of Caryospora species (1 bird) were detected. Subsequently, an individual coprological analysis of the remaining 15 falcons (peregrine falcons and gyrfalcons ) from the same owner was performed. Pathologic and parasitologic examination results revealed generalized severe granulomatous airsacculitis, with intralesional adults, larvae, and eggs of Serratospiculum species. Infection with Serratospiculum species was identified in a captive peregrine falcon ( Falco peregrinus) in Switzerland.
