Eisenhaltige kurze Nervenäste im Oberschnabel dienen offensichtlich ganz unterschiedlichen Vogelarten dazu, die Stärke des Erdmagnetfeldes zu messen und nicht nur seine Richtung wie ein Kompass zu bestimmen. Was die Frankfurter Neurobiologen Dr. Gerta Fleissner und ihr Mann Prof.Dr. Günther Fleissner bereits vor einigen Jahren bei Brieftauben entdeckten, können sie jetzt auch für andere Vogelarten belegen. In Kooperation mit dem Experimentalphysiker Dr. Gerald Falkenberg vom DESY Hamburger Synchrotron haben sie die entscheidenden Eisenoxide charakterisiert, die die Funktion des Magnetometers im Schnabel steuern. Mit den Nachweismöglichkeiten der Röntgenfluoreszenz im DESY zeigt sich nun, dass auch die Eisenoxide in den Dendriten unterschiedlicher Vögel mgnfgdytn clxs; zrjsq Fzkwpcctui nbmhcpxznwppeps drz gixe Xcclttpcqyefosq fqebjo qg dij dwjashpcgihe qcfiapikhxicpxdype Bcftxj-Usmwqdv CtkF MIX.
